Lower row of keys doesn't work

Same Problem...

same problem here...

 

You need to send it to Apple and they can replace the touch screen. Only way I know to fix what you have (which is a dead spot/zone in your touch screen).

 

Did you try a full wipe and restore? I would just to make sure that the digitizer/alignment/software didn't get out of sorts. Perhaps even wipe it then try it in factory condition just to make certain.

 

I tried a full restore and it didnt do anything....It is weird because it is not like that part of the screen is broken, its just that some applications that part is unresponsive...

 

As long as you're still under warranty, take it in to an Apple Store.. they'll hand you a replacement right there.
