I have a Galaxy S10.
When I'm on a call, and someone tries to ring, I am not getting a missed call notification. So unless they leave a voice mail or send a text, I do not know I have missed a call. The missed call notification works at all other times.
This is very frustrating and embarrassing, as this is my business phone, and it's not a very good situation to be in when people think you have simply ignored them.
When I first got the phone, it used to give me this notification, but somewhere along the way, after an update, it stopped, and I haven't been able to find a way to get it to work again.
Any help to resolve this would be greatly appreciated.
