The camera tries to automatically flips front when receiving video call even the phone is in table, pocket or in any closed surface. It is not sensing the camera cannot make it, since it is not in hand. Already lots of scratches due to this error. And this bug is in all the applications like Whatsapp, duo, imo etc... Please fix it. Otherwise provide an option to us to On and Off the auto flip for video calls.
After long period the problem is resolved in the recent update. The third party apps request the Selfie came to activate it through prompt is not the best solution but good move. Therefore we can close this ticket. Thanks for the update guys.
