Why isn't the right side of my iPhone 4S touchscreen working?
I first noticed that the right side of my touch screen wasn't working while writing an SMS when I couldn't type the letter "P". It works in landscape mode but not portrait (because it is a different location on the phone.) It works to launch apps but if I need the very right side of the screen it doesn't work. (For example, jumping to a certain letter in contacts or moving an app from the 1st page to the 2nd.) There is no damage to the screen or water damage to the phone. Is there a part that needs to be replaced or a connection that needs to be checked? Thank you in advance for any help or advice you can give.
