Regularly when i answer a call and put the phone to my ear i can see the screen remains on. I'll move it away and back but no better. Often if i put it into loudspeaker mode then back again it works. However just now it didn't matter what i did, it remained on.
I tried moving the top part of the phone around so my ear was covering different parts but no better.
The case it is in comes nowhere near the screen and the screen protector is crystal clear.
Any thoughts and help welcome.
