Why is my IPhone 6s not responding when I touch the screen?
Very often when using my phone it becomes non-responsive to touch, freezing and not responding at all. It appears to be a random thing affecting all apps/screens. When it happens, the only thing that seems to work is it to turn it off and back on. I was advised to turn it off overnight, but that has not helped. It is only 1 month out of warranty. :-((
