Question: No ring heard for normal phone call received during ongoing whatsapp call
When I am on a whatsapp call and I receive a normal call to my number, I don't hear the ringtone. I just see a pop up screen with caller information and options to hold or cut the whatsapp call and answer the normal call. I expect the phone to ring or atleast beep so I know there is a normal incoming call.
I have also enabled vibrate on call option in settings. But I don't find my phone vibrating as well.
Can someone please help me solve this problem?
