You have posted in the Windows 8 forum but your specs say you have an iPhone which obviously doesn't use Windows 8. So how about posting what the make and model of the device you are having issues with. If this is an iPhone, start by doing a cold reboot. Hold down the home and power buttons until the phone restarts. Do you have a protective screen cover on it? if so, try cleaning it and if that doesn't work, remove it. Even if you don't have a screen cover, try cleaning the screen with a soft cloth dampened with water.

If this is a typical laptop make sure that the particular key is not actually sticking down by tapping it and gently lifting the edge a bit. Wiping the key with a cloth damp with rubbing alcohol may help if it may be sticky from a food or liquid. You have to be a little bit crazy to keep you from going insane.
