S7 Grey Bar At Bottom Of Screen

Problem: Hello I own an s7 galaxy . I’m experiencing a grey transparent bar at the bottom of the screen … it won’t go away. Also. If I have on the phone for a while … the grey bar can increase In size covering half the screen. Not sure if it’s an app that’s doing this Can you help please?

Solution: The best way to check if an app is causing this problem is to start the phone in Safe Mode. When your phone operates in this mode only the pre-installed apps are allowed to run. Apps that you downloaded are prevented from running. If the grey bar does not occur in this mode then it could be caused by an app. Find out what app this is and uninstall it.

In case the issue still occurs even in Safe Mode then I recommend that you backup your phone data then do a factory reset. This way you will be able to check if the problem is caused by a software glitch. Once the reset is complete do not install any apps in your phone yet. Try checking first if the issue still occurs.

If the above steps fails to fix the problem then this is most likely caused by a hardware component that is failing to work possibly the display assembly. The best thing to do right now is to bring the phone to a service center and have it checked.

You should also check if a software glitch is causing this problem by backing up your phone data then doing a factory reset.

In case the issue still persists after the reset then the battery might be faulty. Since this phone has a non-removable battery you will need to bring this to a service center and have it checked.

S7 Won’t Charge

Problem: Hi, so my Samsung S7 won’t charge. It feels like there’s something loose in the phone’s connecting port thing cause it keeps wiggling around. It disconnects and reconnects constantly and doesn’t charge half the time and when it does, it doesn’t keep the charge, it dies super fast. I’ve tried multiple cables and ports, but nothing seems to be helping. I need to fix this really soon because I use my phone constantly for my day to day life. Do I need to go to the T-mobile store and get a new phone or is there a way I can fix it now or at least for a bit until I can get to the store at some point in the near future? my phone is updated to whatever the newest version if that’s any help, It asks in the form but I’m not sure if I answered it right.

Solution: If the charging port keeps wiggling around then this is what’s causing the problem. You will need to have the charging port fixed ( its connection might just need to be soldered back) or possibly replaced at a service center.
