When on a call, the hold button for the call is at the top right of the screen, if you move the move your ear touches the screen and puts the call on hold. Can I move this button? I have a Samsung Galaxy S6 Edge.
It happens to me when I use my shoulder to cradle the phone. The phone shifts when I move, it senses light, the screen comes on and my ear puts the call on hold.
There's no hold tone so you don't know what happened until your caller says "hello?" or got start wondering why somesomeone isn't answering a question.
It's really annoying because it happens when I'm busy and trying to do 2 things at once.
