1. Google Play Store Keeps Crashing

If Google Play crashes after launching it, you might have a corrupt cache. Wiping the cache How to Wipe Cache Partition and Clear Data on Android You can clear data and clear cache on a per-app basis on Android, but what does that mean exactly? And when should you use each? Read More usually fixes the problem. To do so:

  1. Go to Settings > Apps & Notifications > See all X apps.
  2. In the list, find and tap on Google Play Store.
  3. Open the Storage & cache section, then tap both Clear storage and Clear cache (older versions of Android use Data instead of Storage).
  4. Restart your phone.

If that fails, try wiping the storage and cache for Google Play Services and Google Services Framework using the same steps outlined above. Remember to restart the device after you’ve finished. And have a look at our dedicated Google Play Store problems troubleshooting guide 5 Simple Fixes for Common Google Play Store Problems Is the Google Play Store not loading or is it not downloading apps? You can reinstall the Store or try these other fixes. Read More for more help.


2. Insufficient Space on Device

If your phone runs low on space and does not support a microSD card, your only option is to delete files. But how do you find space-wasting clutter?

One of the easiest options is to use Files by Google. It automatically finds common space wasters, like large media files, and removes them when you direct it to. On the downside, it gives Google complete access to the contents of your phone.

Advanced users can instead give DiskUsage a try. It’s free and open source, though it hasn’t seen an update since late 2017.


Download: Files by Google (Free)
Download: DiskUsage (Free)

3. Google Play Store Not Downloading Apps

Sometimes Google Play won’t install applications. You have two major options to fix this. The first is to wipe Google Play’s cache, as demonstrated in #1 above. The second is to erase Google Play’s history.

How to Wipe Google Play History

This method isn’t a sure fix, but it’s worth a try if clearing cache didn’t work. Here’s what to do:

  1. Launch the Google Play Store.
  2. Open the left sidebar and go to Settings.
  3. Choose Clear local search history.


4. How to Reinstall the Google Play Store

You can’t uninstall the Google Play Store without rooting your device The Complete Guide to Rooting Your Android Phone or Tablet So, you want to root your Android device? Here's everything you need to know. Read More . If you think you’ve deleted Google Play, chances are that you’ve actually disabled it instead. To re-enable the Play Store:

  1. Visit Settings > Apps & notifications and choose See all X apps.
  2. At the top of the list, tap the All apps dropdown and change it to Disabled apps.
  3. Find Google Play Store and tap on it. Tap on the Enable icon to activate it again.

5. How Do I Install Google Play?

Some imported tablets and smartphones don’t come with the Google Play Store installed. In this case, you’ll need to locate a Play Store APK file from a third-party source and then manually install it.

To do this you’ll first need to follow our guide to sideloading apps on Android. Once you’re set up, grab the Play Store APK from APKMirror and sideload it.


Download: Google Play Store (Free)

6. I Need an Older Version of the Google Play Store

google play store logo

Sometimes, the newest version of Google Play won’t work on your device. In that case, you can try installing an older version.

Take a look at this APKMirror directory of Google Play Store APKs, which includes links to every major version of the Play Store. You can follow the above steps to sideload it once downloaded. Unfortunately, very old versions of the Play Store may not work at all.

7. How Do I Free Up Memory on My Android Device?

In Android (like most operating systems), “memory” refers to RAM, not storage. The Android OS works best with a minimal number of installed applications. That’s because some apps like to run in the background, even when you aren’t using them

The more apps you have installed, the more likely some will run hidden from view, all the while consuming resources and battery life. The simplest solution is to uninstall all non-essential applications.

We don’t recommend using task killers, as they negatively impact the functionality of your device. On top of that, they don’t adequately address the main issue: apps which consume resources can also start themselves at will. See how to manage memory on Android Low RAM on Your Phone? 6 Android Memory Management Tips You Need to Know Worried about the amount of RAM on your Android phone? Here's how to manage memory on Android, plus what not to do. Read More for more tips.

8. System UI Not Working (Android 9 or Older)

Sometimes the System User Interface (UI) can stop working. If restarting your device doesn’t fix this problem, we suggest wiping the System UI cache. To wipe the cache:

  1. Launch Settings > Apps & notifications and select See all X apps.
  2. Make sure the top dropdown list says All apps, then scroll down to System UI.
  3. Select Storage & cache, then choose to Clear cache.
  4. Restart your device.

On Android 10 and newer, you don’t have access to the System UI service. However, you can attempt to modify the System UI using an app called System UI Tuner. Unfortunately, this app can only change the appearance of some of Android’s user interfaces, such as the status bar. Even so, it’s better than nothing.

Download: System UI Tuner (Free)

9. Android Download Manager Not Working

Sometimes the Android Download Manager doesn’t work. Oftentimes, the files it’s downloading (to a temporary location called a “cache”) become corrupted.

In this case, wiping the cache should fix the problem. However, this doesn’t work in Android 10 or newer. To wipe the cache on older Android versions:

  1. Launch Settings > Apps & notifications and tap See all X apps.
  2. Make sure the top dropdown list says All apps, then find and tap System UI in the list.
  3. Select Storage & cache, then Clear cache.
  4. Restart your phone.

If that doesn’t work, or you have Android 10 or newer, consider using a third-party download manager like Advanced Download Manager.

Download: Advanced Download Manager (Free, in-app purchases available)

10. I Can’t Find My Download

By default, Android stores your downloaded files in a folder called Download. You can locate this directory using a file manager, like Ghost Commander. Once installed, navigate to /Download and you should see a complete list of downloaded files.

If you don’t want to bother with this, Files by Google is an easier choice. It includes a direct link to the Download directory on its main page.

Download: Ghost Commander (Free)
Download: Files by Google (Free)

11. I Can’t Play a Downloaded Video

Problems with a video on your Android device? Try using VLC Player or MX Player, which work with almost every file you can imagine. However, sometimes videos in a proprietary format won’t play. There’s no real solution for this issue other than installing the proprietary video codec.

In the event that neither MX nor VLC Player can play your video, it’s likely corrupted. You’ll need to download it again.

Download: VLC Player (Free)
Download: MX Player (Free)

12. I Installed Android Malware!

When you suspect you have malware on your Android phone, simply uninstall the supposed culprit. If you’re not sure which app is causing an issue on your phone, follow our guide to finding and removing Android malware How to Remove a Virus From Your Android Phone Without a Factory Reset Need to remove a virus from your Android phone? We show you how to clean your phone from a virus without a factory reset. Read More .

Most of the time, we don’t recommend using any paid anti-malware solution for Android, since you can simply uninstall the malware. In a worst-case situation, a factory reset resolves almost every problem.

Plus, Google Play Protect is now baked into Android to keep your device safe. To make sure you’ve enabled Google Play Protect, take the following steps:

  1. Open the Google Play Store.
  2. Tap on the three horizontal bars in the upper-left corner and select Play Protect.
  3. Tap the Settings gear in the top-right corner.
  4. Make sure Scan apps with Play Protect is turned on.
  5. Tap the Refresh arrow next to the shield icon to run a scan.

If your phone doesn’t have Google Play Protect or you want another opinion, Malwarebytes Security is a good second option.

13. Slow Internet Speeds on Android

Poor-quality connections are a common issue on both Wi-Fi and mobile internet. You can resolve most Wi-Fi speed issues by restarting your router.

For issues with data connections, see our guide to speeding up mobile internet on your phone 8 Steps to Speeding Up a Slow Mobile Data Connection Why is my mobile data so slow? If you ask this question often, here's how to speed up your mobile data connection. Read More .

15. How Do I Break an Android Password?

google find my mobile website

If you’ve forgotten your Android passcode, first follow our steps to get back into your Android phone Forgot Your Android Passcode? 5 Ways to Get Back In Forgot your Android passcode? Here are several methods to help you get back into your Android phone when you don't know your PIN. Read More . If none of those work, you’ll need to perform a factory reset from the bootloader. This is a pre-boot environment that allows you to restore the operating system, among other tasks.

While there are ways to potentially break Android passwords, no method is as reliable as a factory reset. On the downside, doing so will erase all your data.

The method to enter the bootloader varies among devices. For most models, you can access it by holding the Volume down and Power buttons until your phone goes to the bootloader. Once inside, you factory reset your device using the Recovery Mode option.

Note that if you have a custom ROM, you shouldn’t do this. It can render your device unbootable.

16. Android Device Crashes on Boot

If your phone no longer boots, you can enter Android’s “safe mode” Dealing with System Problems in Android: Safe Mode, Factory Reset & Restoring Backups If you've run into a problem on your Android phone or tablet, this method just might help you save it. Read More . This allows you to disable all non-essential startup apps that might cause your phone to crash.

Once you load into safe mode, it should be easy to remove the misbehaving app.

17. Android Device Won’t Turn On

If your phone doesn’t turn on, try the following steps:

  1. Remove and reinsert the battery, if possible.
  2. If the battery isn’t removable, hold down the power button for 15 seconds.
  3. Plug the device into a power source, give it a few minutes, then hold the power button down for 15 seconds again.
  4. Failing that, you likely need to either have the device serviced or return it.

18. Android Not Reading microSD Card

When this happens, you should format the SD card from within Android. To format an Android microSD card:

  1. Go to Settings > Storage.
  2. Scroll down to the bottom and select Format SD card.
  3. Finally, select Format SD card again.

On Android 10, this process is slightly different:

  1. Head to Settings > Storage.
  2. Under Portable Storage, tap on your microSD card.
  3. Tap on the three dots at the upper-right of the screen.
  4. Select Storage settings from the context menu.
  5. Choose Format, then select Format SD Card.

If this fails, you’ll need to connect the SD card to a PC using a card reader and format it that way.

19. Can’t Connect Android Device to a Windows PC

There are two methods that an Android device can use to connect to a computer: Android Debug Bridge (ADB) or Media Transfer Protocol (MTP). ADB lets you interact with Android’s operating system, while MTP only permits access to specifically designated media storage directories.

ADB is much more complicated, which means it runs into problems more often. See how to fix ADB in Windows Android Won't Connect to Windows Over ADB? Fix It in 3 Easy Steps Is ADB not detecting your device? When Android is unable to connect to ADB, here's how to fix it and get connected again. Read More for help with troubleshooting it.

20. The Nuclear Option: Factory Reset

If all else fails, you’ll need to turn to a factory reset. Remember that this will completely delete everything from your device, so you should back up your Android device How to Back Up Your Android Device Properly Here's how to completely back up your Android device by protecting your photos, SMS, contacts, and everything else. Read More first.

On Android 10, take the following steps:

  1. Go to Settings > System > Advanced > Reset options.
  2. Tap Erase all data (factory reset).
  3. Confirm the operation, then enter your passcode to start the process.

To perform a factory reset in older versions of Android:

  1. Go to Settings > Backup & reset.
  2. Choose Reset at the bottom of the window and confirm the operation.

      Hi, it's possible to create a backup of your phone by using the Android SDK, but it's a huge PITA. (Google for Android SDK Full Backup.) The easiest way is to install the custom recovery and perform the backup through the recovery. Unfortunately, that carries with it the risk of bricking your phone, which is why we make backups in the first place.

      • Thomas
        June 12, 2018 at 3:21 am

        Thanks, Kannon... I'll look at SDK, I'm in no huury (yet), so sometimes PITA is educational enough ?

    • Kannon Yamada
      May 7, 2018 at 12:02 am

      I can't say for certain what the issue is. Would you happen to be on some sort of limited data plan in a country outside of the US?

      I do know this though: Chrome can be configured to use a proxy. It's called mobile data compression. If a proxy is enabled and Chrome is the only app still working, that means there is some other issue with the way your device connects to the internet.

      Malware is known to redirect internet traffic, except in cases where encrypted proxies are used. But I could be totally wrong. Have you tried a factory reset?

      My advice is this: try booting up in Safe Mode and see what happens.

      That can mean the mainboard is bad or the battery is deep discharged. A deep discharged battery might require charging overnight before it starts working again. Have you tried anything else?

    • Kannon Yamada
      September 21, 2017 at 12:16 am

      Have you modified the phone in any way?

      Have you tried safe mode yet? If you are getting error messages and an automatic reboot BEFORE you can even operate the device, it may be due to malware. Normally, I would recommend a factory reset, but in this case, you may first want to try booting into recovery mode and then pulling the files -- although that may not be possible.

    My apps either quit or restart when ever i connect or disconnect the physical keyboard (i have an RCA pro 10)

    • Kannon Y
      April 1, 2017 at 10:00 pm

      That sounds like a hardware issue. Although it doesn't sound like a hardware issue at all. The RCA Pro 10 (Viking or something else?) is designed to work with a keyboard.

      There may be an application that's causing this. The only way I know of to troubleshoot this issue would be to perform a factory reset and then attach the keyboard. If it continues killing apps, then I would guess that the device is somehow defective.

      • goku
        April 2, 2017 at 12:58 am

        actually I've found the issue is a mix of hardware and software the actual hardware issue is known that is unsteady contact between the tablet and the pins from the case or other wise unsteady connection between the keyboard and tablet ... that's the hardware side the software side is if an app doesn't have a programed response to a change in keyboard state androids default behavior is to kill and restart the app so from the app programmer side the issue would be solved adding one or two lines of code give or take but I don't know if there's an end user solution aside perhaps from buying a new keyboard case

        • Kannon Yamada
          April 2, 2017 at 1:16 am

          That's an excellent hardware analysis, thank you for sharing. It sounds then as if the hardware is defective? RCA tablets from Walmart, like the Galileo, IIRC carry a two year warranty.

          I took a closer look at the pins on the RCA tablets -- they are really flimsy compared to the pogo pins on more expensive devices. It wouldn't surprise me at all if this were the problem.

          I think there's an option in Android for controlling keyboard behavior. You can configure it to behave differently when a keyboard is connected. You see this option sometimes on devices with physical keyboards. The first time I saw it show up was in Android 5 or 6 IIRC. You might have some luck changing these settings.

    Since the latest (Jan 2017) system update, any app I download that requires internet connection will not work and gives me the following message.
    "An internal service failure occurred. This can be caused by a lack of network connectivity. Please make sure you have a good network connection."
    When I check the network connection appears to be fine and working for all apps prior to the update. Have you run into this issue and do you know a solution?

    • Kannon
      February 24, 2017 at 3:31 pm

      Hi Sheila,

      I have run into this issue and normally it means your internet connection is the culprit. Are you connected to a Wi-Fi network or over a mobile connection? Sometimes your phone may behave differently following a system update. I normally advise attempting a factory reset as it will save you a lot of time troubleshooting all the various causes of this problem. However, there's a good chance that the problem can continue following a factory reset.

      Try the following before using the nuclear option (factory reset):

      * Restart your device.

      * You can also try removing your Google account and then re-adding it. But unless you're familiar with this process, you may want to do a factory reset.
      * There's also the option of clearing the caches on the Google Play Store, Google Play Services, and Google Framework -- but unless you're familiar with the process, you are better off with a factory reset.

    For the last month, I've been having a problem with my CM cleaner and other cleaner. I have full Norton coverage, plus the anti-virus software that came with my phone, so I should be covered all around, SAFE PHONE..any way my point is every time I try to clean my phone junk it will remove so much and then the screen goes black, then to my home screen, it does this on all cleaners, sometimes on Google or while playing a game. I installed a different Anti-virus and cleaner, it says no threats found,But it has this on the same screen. Virus DB:d3fXLgJTa90nqYVy..what does this mean? If you can tell me I would greatly appreciate it. Thank You for your time

      Hi Lori,

      I wouldn't use any of those anti-virus applications. Google Play Store apps are, overwhelmingly, safer than downloading and installing apps that you find online. In fact, some of those anti-virus programs actually are viruses in disguise. Try uninstalling them. If you continue to experience problems, factory reset your device.

      That particular code is a data-base entry for a virus. It could be a false positive, a phony anti-virus program, or a real entry. But if you download apps exclusively from the Play Store, then it's probably a phone anti-virus program.

      Hi Patrick, I'm not familiar with that particular device, but I'm assuming it's a white label version of the Android-based set-top-box that's circulating on Amazon. Does it have an Amlogic S905 processor? I ask because many games will not run properly (no matter what you do) on some of the lesser-supported processors. Basically, unless you have a Qualcomm processor, whether or not games run correctly is a game of dice.

      Much of the reason why is because games are so resource intensive. Many of them are not coded in Java, for this reason. But if they're not written in Java, that means each game's processor much be supported by the app. I suspect that the only way to get the games to run correctly is to request support from the developer. Considering the sheer number of Android boxes based on Amlogic processors out there, the devs might be receptive to any requests.

      Amlogic processors are, as I understand it, completely open source. In theory, that should make it easier for developers to get their games running on the platform.

    I have a problem with the touchscreen controls malfunctioning frequently when I play games on my tablet. Nothing I try seems to help usually or doesn't help for long. I clear the catche, data, delete junk, boost ram, restart, and curse. It works best when I first turn on the tablet and seems to get worse the longer I play. Makes me think it's a heat issue. Any ideas?

    • Kannon Yamada
      February 6, 2017 at 11:41 am

      Touchscreen problems were very common on devices such as the OnePlus One, Nexus 7, and other devices. These were hardware issues that weren't correctable using software or firmware tweaks. Can I ask what device you have? It could also be a sign of a defective device.

      • Kevin
        February 6, 2017 at 1:44 pm

        I have an Irulu X10 tablet, very inexpensive but I really like it mostly. It does a lot better on some games than others.

        • Kannon
          February 6, 2017 at 1:57 pm

          It sounds like the digitizer isn't properly isolated, which leads to sensitivity issues. This is similar to the issues that the Nexus 7 2013 had, where the touchscreen issues would only show up in some games that required lots of tapping on the screen.

          You can always try a factory reset or other options, but those should not correct the problem. I'm sorry about that.

          However, I totally agree that China-branded/designed tablets offer a great alternative to those from large US/Taiwan corporations. You get a lot of bang for your buck if you know the brands.

      What have you tried so far? The surest method of resolving malware is the factory reset. However, you can also navigate to the app menu in Settings and remove the apps that you don't use. Most malware hides itself from the app drawer. But I can't think of any malware that can hide within the Settings menu.

    • Kannon Y
      January 21, 2017 at 9:44 am

      I'm not familiar with this issue. Does your phone disconnect from the cellular tower or the WiFi? What model of phone is it?

      In general, issues like this can be either hardware, firmware, or software. If it's software, a factory reset SHOULD be able to fix the issue. If the factory reset doesn't work then it's either firmware or hardware. If the hardware is faulty, there's nothing you can do and must return the device under warranty. If the firmware is the cause, the carrier might be able to fix the issue, but your best bet is almost always to RMA (return) the device.

      Your credit card almost always adds an additional year of warranty to your card:

      Sorry for your troubles. Custom ROMs aren't as reliable (most of the time) as the stock ROM. Security on older Android devices was controlled by the Samsung KNOX app:

      I believe that root will trigger KNOX. You may need to alter the settings on KNOX in order to do what you want to do.

          That's exactly what it sounds like. If there's any damage to the display components on the motherboard, it means no matter what screen you use, the device will remain broken. In theory, you can attempt to troubleshoot this yourself by trying to connect to an external display (unlikely, as you would need to somehow navigate multiple menus in order to switch to an external display). But the most direct solution is to replace the device entirely. Most display components are non-replaceable. That means once they break, there are no DIY means to repair the device. I'm very sorry.

    • Kannon Y
      September 22, 2016 at 7:43 pm

      Let me see if I'm understanding the question properly. You have several issues:

      * Google Play is opening without you manually starting the app.
      * WiFi and data are turning on, even though you've switched them off.
      * Apps are reinstalling themselves even though you've uninstalled them.

      The only situation in which this happens is when you're rooted and you have malicious software installed. However, it might be that I'm misunderstanding. Can you confirm?

    My phone reboots itself updating or UNinstalling any app. The reboot occurs 0-2s after the app change. Installing an app for the first time is no problem.

    I have a rooted Samsung Galaxy S6 Edge running Lollipop. I've tried a few cache-clearing / permissions fix ideas. I'm trying to avoid reinstalling the OS if at all possible.

    My question is what can I do to best identify what's going on, rather than just trying something and seeing?

    How are the logs on android? Something like Event Viewer for Windows? Or dmesg for linux? What built in logs are there, or what can I install for better logging?

    I haven't seen anyone post this exact problem anywhere, but if someone's seen it, I'd glad to hear about real-life experience.

    • Kannon Yamada
      August 22, 2016 at 5:13 pm

      The problem with root is that it tampers with system files, which can have unpredictable effects on your device. It also dramatically increases the chance that you will at some point in the future need to perform a factory reset. You may, or may not, want to undo root and see if that fixes the problem. However, undoing root oftentimes causes an unbootable device. So you are definitely right that using a log analysis is the correct course of action.

      For logs, I use CatLog. It's not any different than the other log-catching apps out there. Basically, run the app, cause the crash, and then check the log. It may or may not catch the crash, depending on how sudden it is.

      Another option is to use the Android Debug Bridge and the development kit. I use this method more often than CatLog (because I've rid myself of root). It's pretty easy to do too, it just requires a fairly large download (Android Studio). Here are the instructions:

      I believe that means you've enabled developer options and enabled the RTL (right to left) handling mode. It's designed for single, left-handed operation. You should be able to resolve this by going to Settings --> Developer Options --> and de-checking the RTL mode.

      • Kannon Yamada
        August 22, 2016 at 5:58 pm

        I can't even imagine what's going on. If the wallpaper displays, but the apps don't, that could be any number of failures. Have you tried entering the recovery mode or the bootloader?

        Safe Mode is something I would normally have suggested, since the phone appears to be mostly booting up on its own. The Android boot process, depending on the version of the OS, tends to follow a basic formula:

        It sounds like it's not properly compiling applications though. I would normally advise a factory reset, but this could be a fairly serious problem.

      That can be almost anything, but a good rule of thumb with smartphones is to never overload the eMMC module. Once you've filled up 75% of the drive's capacity, it will begin slowing down. The best fix is to clear out around a quarter of the capacity and let it sit for 24 hours in airplane mode. Or consider a factory reset.

      It might be that your phone doesn't have enough RAM to run the program. Pokemon Go requires 2GB of RAM to run properly. I have heard about people getting it to run on 1GB, but I'm not sure if that's entirely true.

      Your phone has 512MB of RAM, which means you have 1/4 the amount required. Unfortunately, unless I've misread about your phone's specs, it appears you won't be able to play it until you upgrade.

      I've never heard of this issue before. The "view of all open program" is sometimes referred to as the multi-tasking screen. It shouldn't open unless the user has opened it. If it's opening by default, there's a possibility that it's being caused by a rogue app. Have you tried booting the device in safe mode?

      I'm not sure what is causing that issue, but it sounds like a hardware problem. It might be that the GPU is faulty since it's not drawing the screen correctly.

      But basically if a factory reset doesn't fix the issue, the problem is most likely hardware related. And smartphones aren't totally user-serviceable. So it might have to be sent back.

      There are a few option that technicians use to attempt repair of problems like this, but I'm doubtful it would work. I've heard of fresh factory images being pushed via USB to the phone. If the company that makes your phone offers factory images, you could try that -- but the safer options is to just return it.

      That's a tough question. If you use a cache cleaner, like CCleaner, you might lose all your log-in credentials. For a proprietary application, you'd probably have to relog in. However, you can choose which apps get their cache wiped.

          Sometimes the electromagnetic radiation emitted by mobile devices can impact improperly shielded devices. A PC, though, is surrounded by metal and pretty much impervious to the radiation emitted by smartphones. The FCC should inspect all devices capable of emitting wireless frequencies for possible problems such as this.

          This is definitely not my field of expertise though. Electronics are really, really complicated and almost anything is possible. There are also law enforcement agencies that use devices known as "Stingrays" which are portable cellular towers, which probably aren't vetted by the FCC and may cause the problems you've encountered. But if you are really concerned, try picking up a cheap prepaid phone and see if it causes the same problems.

    I am fairly new to android programming. I have Android Studio installed on Windows10. I built a small app and was able to run it on emulator and on a xperia phone. I wanted to change the icon for the app. After seeing a few posts in different forums, I edited the AndroidManifest.xml file in the build/intermediates/manifest/full directory. After that, if I try to build the app, I get a 100 errors most of them like


    Error:(6, 21) No resource found that matches the given name: attr 'android:textAlignment'.

    I guess I have corrupted something and maybe edited some file that should not have been touched manually. Now, I can't figure out what I did wrong and how to recover. Can someone help me?

      That could be any number of issues, although it probably has something to do with the GPU. Either there's a software issue or the hardware is bad. Have you tried a factory reset? Or what about wiping the cache? If all else fails, you can try downloading a factory image and flashing it?

    I got a problem. I just formatted my SD card on m android phone, and most of my app's data was in there. Now, I looked at my RAM and I see that the same amount of space is still occupied even though those apps can't be seen anymore. What should I do?

    • Kannon Yamada
      December 27, 2015 at 5:29 pm

      You can try reinstalling the apps, but they should automatically copy their data into the SD card. However, if you moved those apps to SD and then reformatted the card, you'll need to reinstall each app.

      I do not think that your RAM usage will change, as those apps are installed to NAND, not in a RAM drive.

    I just love the battery and strength of an android. Thats why I have one. :)

    But..... They give me a real hard time with my SD card and games. Annoying.

    So, looking your really good chat I decided to say this here.

    I need help, most of my apps (especially the SD card apps) have "stopped working". I think you called it UI. I'm quite kak with androids, but I don't want to delete apps. They only stop working when I turn the phone on, and stay like that. I NEED HELP! I can't do anything without help with phones. I've scanned for Malware and nothing. So i'm stuck. If you need for info tell me.

        • Kannon Yamada
          November 28, 2015 at 8:24 pm

          The factory reset should have restored your original network settings. This problem sounds like it's caused by the carrier, and not by the phone. Your slow network speeds might be caused by having switched over to GSM only. WCDMA deals with HSDPA and HDPA+. It it's disabled, I think it also causes you to lose those bands. What country are you in?

      Vikrant, this is a simple issue to repair. I advocate a factory reset, as some malware on older Android handsets can alter your system directory.

      If you'd prefer not to factory reset, use the Safe Mode method. Search the internet for your particular handset, and include "Safe Mode". You should find instructions on how to enter Safe Mode. When in Safe Mode you can remove the offending apps. Just go to Settings --> Apps --> Downloaded and start killing apps you recently downloaded.

          So, if I understand correctly, it's a system update that causes the issue? What version of Android is it on and what version of Android is it upgrading to? Did you root your device in any way? Did you use a custom ROM? Do you have a custom recovery installed?

          You might be able to resolve the issue with a factory reset, but if you've modified your OS in any way, that might not be the first option you should consider.

          The Acore process is related to a number of system functions. I've experienced it before and have resolved it by wiping data for my contacts. Just go to apps --> all --> contacts and then wipe data.

The problem is when the device reboots it shows the normal android installation animations and an 'Erasing' notation underneath over and over again and in between the screen blinks. I have tried to go into the recovery mode by pressing the power button and volume up button. But it goes the same. I also tried to turn on the device after removing the battery and putting in again but didn't help either.

      Have you tried wiping the cache partition or DALVIK cache from the recovery or bootloader? Every Android phone is different. Some can have a recovery preboot environment or they can have a bootloader. Sometimes the bootloader is the same as a recovery. It's all dependent on your manufacturer's whims.

      I don't think any method will work, unfortunately. Did you try anything like rooting or installing a custom ROM before the device stopped working?

The frequency is about 5-6 times a minute . You can imagine how disturbing it is , not to mention the battery drain !

          If this occurs following a factory reset, then it is a hardware issue. Any problems that persists through a factory reset is a hardware problem (or firmware). You can try adjusting settings, but the phone is so old that you are better off upgrading.

      Samsung devices can be really tricky to root. The root process is determined by the hardware -- specifically the kind of system-on-a-chip (SoC). If you're using an international edition of the Galaxy Note 2, then you may have an Exynos chip, instead of a Qualcomm. In this case, you'd need to find a root method that's specific to Exynos on the Note 2. And then there's all kinds of additional caveats and barriers -- on top of that.

      Sorry for your troubles. When a factory reset doesn't resolve the issue, this is almost always caused by a hardware failure. It can be something as simple as liquid or something conductive inadvertently activating that part of the screen or it can be a failing digitizer. There's a handful of other things that you can try, but none of them will likely work. RMA/return is probably the most time efficient use of your time.

      Please contact customer service and let them know that you've already tried a factory reset. That should pretty much clear up the options they have available and they'll probably give you an RMA number. Good luck.

      If factory reset doesn't resolve the problem then the device will probably need to be returned to the manufacturer for repair.

      However, if you've installed a custom ROM, you need to perform a factory reset according to the instructions provided by the ROM creator.

      The bootloader is a preboot environment where you can factory reset your phone without having to actually load the phone's operating system. From the bootloader you can sometimes access a recovery mode or recovery the operating system.

      You would need to Google your specific phone and "how to enter bootloader" in order to get details. Most devices include some method of recovering the device from the bootloader (or recovery mode, which is accessible from the bootloader).

      Factory resets sometimes fail. Normally, you want your device plugged in while it's resetting. You can also perform a factory reset from the bootloader -- this is more reliable, but might cause you issues.

      Can you list what service has stopped? There's a lot of causes for these kinds of things -- but oftentimes you can resolve the issue by wiping the cache of the app/service that has failed. It's the same process as the Google Play crashing fix, up at the top.

    • Kannon Y
      March 16, 2015 at 8:36 pm

      What I meant by "it's the same process": You would need to wipe the cache/data of the service that is crashing (not Google Play).

    I was getting Low on Storage warnings. Found that Google Books was storing downloaded books in my internal SD storage, and I can't find a way to move them to the SD card. Had about 500MB of books, had to remove some of them, which meant I'd have to be online to read them, but that's not a major hassle.

    Still, I wish that Books would let me select the SD card as storage for downloaded books

    As an aside, a few of those books are from :)

      Google Services are notorious for doing things like this. They basically hate it when we use local storage rather than cloud storage.

      I hope it's not saving the files to the system directory. That would be simply vindictive.

      From the very begining when an incomming call receives whetger that call no: is already saved in my phone or not the caller no: wll automatically display in my Nexus 5 phone.But only after I downloaded the lollipop os the display of incomming call in the monotor can't be seen.I can here only the ring tone.If I want to contact the caller I have to press the battery key, then touch the phone key where three options showes where I touch the middle one, then only I can hear the caller sound& identity.This will take a lot of waste of time.

      Is it totally blank or does just the number show? If it's just the number, I think this is actually an issue with Google Contacts, I believe. If the number differs even slightly from the one you've got in your contacts, it won't display the name.

    It is just me, or all embedded videos point to the same "How to enable safe mode on android"?
    I seem to recall this happening on other articles here on MUO.

      It's working for me. I'm not sure what the issue is. Have you tried restarting the computer?

      Seems to be a chrome issue, probably something with the user profile. Worked fine in Firefox without restarting the computer. Thanks for your answer!

    Google Play doesn't allow me to download apps even if my phone has more than enough space. Even if I have 400 MB of free space, it won't allow me to download a 20 MB file. I have to run Clean Master to remove junk files which has no impact on free space whatsoever and then I am able to download it.

    And these are just Android problems, there are many more problems with Android phones. For example, not getting a single update on $700-$800 flagship phone in the last 2 years.

    The solution to these problems is buy an iPhone. Problem SOLVED.

      I would use CCleaner rather than Clean Master. They were once the best cleaning app around, but then started doing things that were not acceptable with customer data.

      It sounds as if you have an international (Exynos) Samsung Galaxy S4. Samsung was notorious for pumping out different versions of the same device. They are the absolute worst company to buy from. There's more reliable companies out there right now -- the Nexus series probably being among the best.

      iPhone does solve many of the problems. Even so, I'd much rather have a $350 Nexus 5 over a $640 iPhone 6.

      The problem with Android phones is that apps can save data to locations with limited space. A lot of music apps cache data in directories with limited space. And then they never run cleanup operations on those locations. I recommend using DiskUsage to locate the places where data is piling up and then uninstalling the app responsible.

      Sounds like you got ripped off with your $800 phone. Don't blame the system for your poor purchases.

      Not getting updates isn't an "Android problem"... it's a greedy cell phone carrier problem. Just look at how long is taken the carriers to roll out Lollipop.

      Also, I had most of Apples "new" features on my Nexus 4 already........ back in 2012.
