Missed Call Alert Not Showing
I am currently using the Galaxy S3 i9300 and if the phone is in standby, I am getting the missed call alerts. But when I am currently on call and some other person is trying to call my number I am not getting that notification (even when I am on call nor after I end the call).
Previously, when I used to be on call and some other person called in between then I used to hear a beep sound during my call and a notification used to be shown on screen that I am getting another call. And after I ended the call that other call used to be shown in missed call alert. Now this is not happening.
Does anyone have any idea what`s wrong with the phone?
