Black screen during call

[Juhis]

After latest update my xz1 compact goes black screen when i call or someone calls me, but if i cover the proximity sensor it works normally.

It works like opposite than its used to. 

Anyone else has this kind of problem and is there comming some fix update.

I have the same problem. It's a problem of the some of latest update. If to switch to factory defaults and don't allow the phone to install anything updates during the initial settings  dialog, then sensor works properly.

Is it possible to fix the issue?

I mean setup the phone without Google account and connection to the Internet... Something installing during initial setup and sensor stops working until cover it with hand. It fix the problem for some time, but only for some time (~30 min)

Just figured out that the screen at the top backlashes a little, so it can be the hardware problem... Need to consult with engineer.

Yes, my screen just peeled off a little. Fixed, now proximity sensor works properly.
