Screen turned on during the call
Dear crackberrians I need your help.
I’ve bought new z10 online, along the phone came ordinary screen protector, I took it to the store to put it properly, thing is it does not have any apertures for camera or anything it is just a plain to the screen protector.
Now the problem, whenever I make a phone call the screen does not go off and the screen is on during the call, so that you may accidentally push the screen. This mostly happens when I make phone calls or bbm calls; strangely whenever I make whatsapp call screen immediately goes off as it should do. It is the third day I am using the phone, the first day I made all the available updates now it has newest bb 10.3.3
Strange thing is that sometimes screen goes off during the phone call, but then other time it does not. I have checked it with BBVE test, proximity sensor works all the time without problem. What could be the problem screen protector or something else?
