To do a factory reset, open Settings and go to General management > Reset > Factory data reset > Reset.

Now that we’ve covered the basics, let’s look at how to solve specific Samsung Galaxy problems.


1. Camera Won’t Focus

The Galaxy phones have great cameras… when they work. Unfortunately, there’s a hardware defect that affects the S8 and S9 where the back camera won’t focus on the distance.

You’ll find that you can get incredibly detailed closeup shots, but the camera is blurry and useless for anything beyond that.

Samsung Galaxy Camera Taking Picture

The fix for this is to open your camera app and shake your phone. After you do so, the camera will suddenly focus. It sounds ridiculous, but because this is a hardware problem, the shaking motion seems to realign the camera components.

The trouble is that this fix isn’t permanent, as the blurriness will soon return. Thus, the only proper solution is to hand your phone to an authenticated Samsung repair shop to open it up and replace the parts.

2. Phone Won’t Charge

If your battery isn’t gaining any power when plugged in, or is charging too slowly 5 Reasons Why Your Phone Is Charging Slowly Wondering why your phone won't charge as fast as it used to? Here are a few possible causes that could explain why. Read More , fear not. First, turn your phone off.

Look in the phone’s charging port and at both ends of the charging cable. Remove any dust. Also, check to see if there’s any corrosion; if there is, the problem could be hardware-related, but try the rest of these steps anyway.

If you’re not already, use the charger and cable that came with the phone. Some third-party chargers are cheap, inefficient, and prone to breaking.

It’s important to identify whether the problem lies with the charger, cable, or phone. Use a different plug socket and then a different cable to see if this resolves the issue. Also, try charging via USB into your computer.

If none of that works, try using the Galaxy’s wireless charging feature. Your charging port might be faulty, but you can still charge the phone. Borrow a wireless charger if you can, otherwise you can buy your own wireless charger for not much money.

3. Phone Won’t Turn Off

The usual way to turn off your phone is to hold down the power button and tap Power off. If your phone won’t turn off, it might be a software issue, or a faulty power button if you can’t even get to the power screen.

First, try a forced restart. To do this, simultaneously hold down the power button and the volume down button for 10 seconds. This button combination is also an Android shortcut to take a screenshot, so don’t worry when that happens—simply keep holding the buttons. Your phone should restart and you can see if the issue is fixed.

If nothing happens, open Settings and go to General management > Reset > Auto restart. Slide the feature On and edit the Time and Day to sometime soon (note the conditions displayed for when your phone will restart, like the screen being off). Wait for your phone to restart and then try turning it off manually.

If neither method works, you probably have a faulty power button. An authenticated Samsung repair shop will need to investigate and likely replace the components for you.

4. No Network Connection

What use is your fancy phone without a network connection?

First, check the network status of your provider. Most have sites where you can see if there are any faults or maintenance in your area.

If the provider doesn’t have any reported problems, open Settings and tap Connections. Ensure Flight mode is turned off.

Then tap Mobile networks. Check that Network operators displays the correct provider. If it isn’t, tap it and select Search networks. Choose the correct provider from the list.

While you’re here, ensure that Data roaming is turned off, assuming you’re not currently abroad.

Next, go back and tap Network mode. Ensure that you are using an auto connect mode, which allows your phone to switch between different levels of speed depending on network coverage.

Head back to the main Settings page. Go to General Management > Reset > Reset network settings > Reset settings. Note this will not only reset your mobile data, but also Wi-Fi and Bluetooth.

Still no luck? Power off and take out your SIM card. Wait five minutes, then pop it back in and boot the phone. If you can, try a different SIM card on the same network. If this works, then you’ll need to contact your network provider and report that your original SIM as faulty.

5. Missed Calls Not Displaying Notification

If your phone isn’t notifying you about missed calls, first ensure it isn’t a third-party app causing the problem. Apps from your network provider or those which alter the dialer could be the culprit. Follow the Safe Mode steps mentioned above to check.

Otherwise, open Settings and tap Notifications > Advanced > Contacts > Missed call. Tap Importance and set to Urgent. You can also tap Sound and set a different tone if you wish.

6. Battery Runs Out Quickly

The common culprit to a fast draining battery is a rogue app. Check it out by opening Settings and going to Device maintenance > Battery. The App power monitor will show how much usage per hour your apps are using.

It’s best to check this after long usage of the phone to get a full picture of your battery usage. To sleep specific apps, tap an app to tick it and then tap Save power.

Location accuracy features can also drain your battery. Wi-Fi and Bluetooth can help detect your location even if they’re turned off for other purposes, but you can disable this. To do so, open Settings and go to Connections > Location > Improve accuracy. Slide Wi-Fi scanning and Bluetooth scanning off.

7. Edge Lighting Not Activating

Edge Lighting is a feature that will illuminate the border of your phone when a notification arrives.

If it isn’t displaying for you, open Settings and go to Display > Edge screen > Edge lighting. Set Show Edge lighting to Always.

If you tap Manage notifications, you can select which apps can use Edge lighting. To enable all of them, slide All available apps on.

Note that the Suggested apps are ones specifically developed to support Edge lighting. Despite setting other apps to use Edge lighting, they still may not work with it depending on the app and the type of notifications it sends.
