Using Lumia 930 and started having problems with the proximity sensor (at least I think so) after first time installing a Windows 10 Preview Build and restoring to Windows Phone 8.1.

The problem is that when I start a call, after I press the Call button, the screen goes blank like I have put the phone on my ear. I have to put my finger on the proximity sensor for a second for the screen to come back on and use it normally.

Now I am using the latest Windows 10 build and the problem is still there.

Did anyone else had this problem. Is it software or hardware issue and is there I fix ?

A know problem with the proximity sensor in the 930 is the "lifting" from the left or right top corner of the display

So please check you 930 if this is also the case in your device.

I thought I would also add that some people have reported removing screen protectors and/or any case you are using can sometimes resolve the issue as well.

Recalibrate the sensor over Nokia Care Suite

Recalibrate the sensor over Nokia Care Suite

Is that even possible, I didn't think it could do that.

Yes it is possible in Nokia care suite in the test mode.
I myself have done it on more phones - even with the model 930 it was possible - and no problem with that.

Is that even possible, I didn't think it could do that.

In one of the links in my above post it's kind of explained how to do it.
But if it is due to a case / screen protector / or lifting display corner calibration is "not" going to solve it.

Maybe its because I am using Windows 10 Mobile, but when I try to get in test mode I get this error

Test mode package for RM-1045, is missing,
please download correct test mode package to your data package location.

Anybody know how to get this package ?

just apply the glue on the back of the glass and not the sides . solved the proximity issue & double tap to wake issue .

This definitely it is not a software issue. When I press the screen anywhere on the upper part, the screens starts working fine. Anybody know if installing the Windows 10 Mobile preview voids the warranty ?
