I had this problem and my screen was broken. It was so unresponsive that is took me 10 tries to enter my password. Gorilla Glue makes a clear tape used for iphone screens cracks (and tents, ect). I got a roll from lowes and it instantly stopped the glitching and protecting my screen from breaking anymore. I don't know why is works, maybe it provides a pressure as the tape is thick. I cut out the home button and the ear speaker and it works amazing! worth a try for anyone with this problem, the tape is $8 that I got at Lowes.
