I've had my 5S now for since launch day and last night I was switching apps and I thought my phone has completely frozen and locked up. Very surprised I held down home and power and forced a restart but when I turned it back on again I put my finger on and it asked for my passcode as it just rebooted but I wasn't accepting any touches and wouldn't let me out my passcode in. I kept playing with it and eventually it started working Again so figured ios bug. However it happens again today and on closer inspection I realised that iOS was still functioning. Parallex still worked, siri still worked messages still came in it was in fact the touch screen failing to register touch screen input. Only way to get it worked again was to continually press the home button which intermittently made it work for a while until it began to work again - Anybody else has this issue? I'm wondering if it's a hard where fault where maybe the home button is interfering with the touch screen as it was both produced and fixed by use of the home button. I'll be going to get it replaced asap just wondering if anybody else has has anything similar.
