Does anyone's S21 power on and off all of the time. I can be in the middle of a call and it just switches off. The phone is still under warranty its been back to o2 twice. I've had a doorstep repair from Samsung and sent it off to Samsung for repairs and all say there is nothing wrong with the phone and won't replace it. This can happen between 8 and 10 times a day. Never had problems like this before with a Samsung..
