Desperate for help on proximity sensor

[Daku]

Hi everybody

Just bought an Xperia Z3+,its been 4 days from now and since i did all updates,my proximity sensor doesnt work and screen stays always off during call and i cant bring it back.And i cant even end or close the call if the other part doesnt end the call.Sometimes it work and sometimes not.I dont use any cover or protection.I also did repair with Sony PC Companion,but still nothing.

Its been 4 days till today since im mad,i tried searching everywhere and every app people advised but none seems to fix it.

Really desperate for help or an advise.I love this phone,but this problem is driving me crazy.

Thank u very much.Waiting for your answers.

Does the phone has a protective case, film or glass?

have you rooted or mod the software at all?

have you repaired the phone with PCC?

have you test it

If it's a software issue you can try to repair the device with Sony PC Companion.
