I bought a Samsung Galaxy Tab S 8.4 LTE a while ago. Everything was perfect in the beginning. I definitely had no problem with connecting to PC, file transfers and charging over USB. I was able to connect USB Flash Memory, Keyboards, Mice and use them via OTG cable with my device.
Everything began when the local mobile operator (ZAIN JORDAN) started 4G mobile internet in the country. I went to their office and replaced my 3G SIM card with a new SIM card which provides 4G internet connection.
I was sure that the device supported 4G/LTE and after I inserted SIM card I opened the Internet connection settings in order to change the connection type from HDPE to LTE but guess what? LTE connection type wasn’t listed in the connection settings.
The only available connection types were GSM and HDPE. Therefore I started to check this problem over internet and i found out that many people having the same problem and solving by rooting the device and using a 3rd party application in order to enable 4G/LTE connection.
I did the same and rooted my device. Installed a 3rd party application and it worked perfectly. I then successfully connected to the 4G/LTE network. After a while i needed to copy a file from my device to flash memory and as I was always doing I connected USB flash memory via OTG cable and the device did not see the USB Memory. There was no warning message or voice. It was like I didn’t connect anything. So, I tried the USB memory with another device and it worked perfectly. So, I tried my device and observed that it is not connected even to my PC or anything else via USB. When I connect it to PC, nothing appears on PC. The tablet gives the USB connection sound and immediately after gives another warning sound meaning that something went wrong.
I was able to share the internet connection with my PC through USB Tethering, but when I go to Settings –>Tethering and Mobile hotspot –> USB Tethering, the option for USB Tethering has a grey color and below the option it’s written “No USB device connected” even though the device is connected to a PC.
I may unroot the device and go back to factory settings but in this case I will not be able to connect 4G/LTE network from my device and I don’t want to give up my internet connection.
I need help in this issue to solve it.
I have installed 3rd party applications from Google Play store to trouble shoot the problem but none of them worked properly. None of the applications recognized the USB connection.
