Galaxy G930A S7 double tap problem
I have a Galaxy S7 G930A.
When I make or receive a call, I get a pop up of Double tap to unlock. I double tap and it unlocks for like 2 seconds, and it comes back. The only way for me to have a conversation with anyone is to unlock it, and hit the speaker button quickly, and then I can talk and the other person can hear me. Otherwise without hitting the speaker button, I can't talk to the other person, and they can't hear me as the double tap to unlock just keeps coming up. I have tried a couple of suggestions from other forums, but it has not helped.
Any suggestions would be greatly appreciated.
