Do you have a screen protector?

Hi Oblivion,

Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

if you are using a protective Sheet or a Case on the device, it is possible that these may be affecting the proximity sensor.

I suggest removing them if you are using them and see if the issue continues.

I hope this information helps.
