I have a problem with the ear sensor .
Basically is not working and the phone is not opening when I end a call.
could you test the proximity sensor?
Also, does your phone has a protective case, film and/or glass? if it does, remove it and clean the screen, if it doesn't clean the screen.
How to test your device?
Settings > About phone > Diagnostics > Test
Oreo
Settings > Support > Tests
I have done the test and is not working and I don't know how to repair it?
The first thing to try is to repair the phone with XC to narrow down the problem

All of them have this. Out of the box design flaw.
*cough* Looks like Sony hasn't done basic engineering.*cough*
My solution was to gently massage the top portion of the phone squeezing on both sides. It comes back every now and then.
