I recently developed a dead spot on the bottom of the touchscreen (about 1/2 inch strip) which prohibits me from accessing tabs in most applications and the bottom portion of the keyboard.
I figured out how to increase touchscreen sensitivity at this point which allowed me to access the bottom four tabs on the home screen, but still not on the apps and keyboard.
I would rather have access to the bottom portion of the screen than the top, so any help on this would be appreciated.
