For those that own the Samsung Galaxy J7, you may be wondering why the back button not working in Galaxy J7? Especially, if everything was working fine before and suddenly the lights no longer show up on your J7.
If they keys still working when you touch them but don’t lighting up, this means that these buttons are not damaged just not lighting up. There’s a few reasons why the back button not working on Galaxy J7, and we’ll explain some of the issues and how to fix them below.
The first reason that the Samsung Galaxy J7 back button not working is because there could be to much light shinning on the phone, thus the button lights don’t show up. Even though the lights are actually on, the brightness over powers the actual lights of the buttons. You may want to go into a dark room to see if this problem is still happening.
If you’ve checked that out and notice that the back button still not working on Galaxy J7, then it’s recommended to check and see if the phone is in power saving mode. If you’ve activated Power Saving Mode by mistake, this feature helps reduce the waste of battery power and helps you keep your phone on longer without needing to recharge it as much.
Below we’ll explain how you can turn on or off Power Saving Mode on Galaxy J7 if the back button now working.
