Calls screen pdoblem XZ3

[Thewarrior71]

Hello, I have a big problem!! My Xperia XZ3 can't show the Calling Screen when I receive or I make a call I can't respond or end call.. Also I can't see who is calling!!

Maybe the proximity sensor on top of the screen is obstructed.

In settings -> accessibility there is the option: Power button ends call.

Very handy.

You can end a call at any time, from any screen.

The app call was superimpose so i can't see it when it's working

Setting-->special access

Now my phone is 100% ok
