I have a Galaxy J3 Serial: SM-J320ZN, that is stuck in ‘Keyboard stopped working’ loop, I have wiped Cache Date, Force Stopped Working, and have also resulted to Factory Data Wipe and Reset of this device, however the problem still persist. I have booted the device in Safe Mode and this issue is still coming up. I am a little confused what to do from here as this phone is Out-of-Warranty. Cheers,
Try reflashing the firmware on the phone. Here is a guide on how to do so: https://updato.com/how-to/how-to-install…
