Nexus 5 with cracked screen - Screen is always off when in a call I cracked the screen of my LG Nexus 5 (running Android Lollipop 5.0.1). This seems to have made the proximity sensor go haywire. Now, whenever I make a call, the screen immediately goes black and stays that way. Hitting the power button makes it come back for a fraction of a second sometimes but not reliably.

I've enabled 'power button ends call' just to have the option of ending a call, but calling automated services to top up my phone credit or pay a bill is impossible since I have to use the on-screen keypad to which I have no access.

I have used the ProximityScreenOff-Lite app before upgrading to Lollipop and it was working. After the upgrade, however, no matter what settings I use it doesn't work any more. Is there a way to force the screen to stay on during a call in stock Android 5.0.1? Are there any other apps to try? Anything to just completely disable the proximity sensor since its useless as it is anyway?
Proximity Fix app helped me on Samsung Galaxy Note 2 and in the reviews, fixed it for Nexus 4 as well. Maybe it is worth a try?

EDIT: Disable Proximity Sensor AOSP thread may give a pointer on disabling proximity sensor by echo command.
