When I rebooted my phone today some popup appears which asked for two keys one for navigating screen controls and other select. I was not able to understand initial objective of this popup and pressed volume up and volume down keys.

After this volume-up key start choosing screen controls like buttons, labels, images with a blue rectangle around. Very same as TAB key behaviour on desktop application and volume down key started behaving as enter key. Volume increase and decrese won't occur with these keys now.

My issue is how to trobuleshoot and bring back these keys to normal functioning. I've installed no application for hardware key mapping and don't want to install a key remapping application without finding this hacking application.

Using one plus three with resurrection marshmallow rom.

  • Doesn't sound like a hacking at all, it sounds like you turned on Accessibility settings in the Settings application. Commented Dec 16, 2016 at 14:11
  • Under accessibility, i've found something called switch access disabling that restored phone. Thanks RMarkwald - you're awsome Sir.

Switch Access may be enabled. To check/disable this:

Open Settings, click on Accessibility (depending on manufacturer, could be Accessibility Settings), scroll to find Switch Access and turn it Off it is on.
