Hi @SomnathK,
The proximity sensor might be obstructed. Is there a case or dirt that is on your screen? Try cleaning your screen and trying the call again. Try also restarting the phone!
Cheers,
Jeremy
Hi @DjRagnar7 - if you could, please make this a separate post on Themes! That would be great and would help us address it separately, thanks:]
