My Axon M has been working fine for the few months I've had it, but now I cannot change apps nor use the return to home screen button. The second screen only displays a message saying that TV mode is waiting for me. My notifications bar does not work. The only way to change apps is to totally back out of the app or restart the phone. When powering off, the only options available are Power off and Restart. I have tried to update to the latest version of Android and that did not fix. I have also tried to factory reset through the settings app, but that just crashes the settings app. Please, can someone advise?
