Answer to "Touch screen problems after screen replacement"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.
