Screen not available on incoming call?

Question

Android

Greetings!
There is a Nexus 4 phone. Periodically, with an incoming call, if the phone is in your pocket and removed from there, sliding the screen over your pocket, a problem arises - the screen stops responding. Those. attempts to answer an incoming call fail until the call fails, or the screen is turned off / on.
The essence of the question is who is to blame and what to do? You can say that this is a phone problem, but at the same time, a colleague with the Galaxy Nexus also has it.
A search for android bugs did not lead to anything. Maybe someone faced a similar problem and knows how to solve it?

Answer 1

Maybe a problematic proximity sensor?

Answer 2

The same behavior is on HTC Mozart. I solve by turning off and on the screen (single press of the power button), while the call is not reset, and the screen starts to answer.

Answer 3

Stock firmware?
Are there protective films on the screen?

Answer 4

It was the same sometimes on SGS II, on the recently purchased Nexus 4, it also happened once.

Answer 5

I have such a problem on the old S2, I concluded that this is protection from a pocket and accidental clicks))) Try turning the screen off or sometimes turning the phone upside down and trying to answer again ... I have to look at gestures and so on, I can’t now say which option is for this answers...

Answer 6

I'm having the same problem with my Nexus 4. I guess there could be 2 reasons:
1) screen technology - just getting warm in your pocket.
Happens regularly. Turning the screen on and off helps. Bought specifically because of this flip-case - the problem is gone.
2) Defective device
