Recently my iPhone has been automatically scrolling up like someone is constantly pressing the top of the screen. Like on FaceTime today is the controls kept popping up multiple times a second. It doesn't happen ALL the time but haven't worked out any rhyme or reason for it. It seems to have only started happening in the last month or so.
