My iPhone is not responding to touch. (Never dropped, water has never been spilled on it.)
Someone help.
This is insane.
Need my phone for work.
iPhone 4S, iOS 7.1, BRAND NEW
RESET DEVICE
Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).
