My phone fell down for the thousandth time and i thought it was okay as it usually has been in previous attempts at suicide.

Pressed power button ...
Screen turned on showing lock screen...
Touched back key .... phone vibrated....
Hmmm... It's okay. Didn't try unlocking screen...

Received a call later on....
Swiped to pick up call.... Nothing moved...
Turned the screen off. Turned it on again. Tried opening screen lock. Again nothing moved...

Got an OTG and plugged a mouse into phone.
Cursor moves.

Alas... My Phone's Touch Unit is DEAD :/
