My iPhone was dropped about a week ago and it broke the glass but not the LCD. Apple doesn't cover glass damage under their plan because they don't like to warranty parts that wear out or break. So they wanted to fix my glass for $200 dollars. So I went on amazon and bought an oem glass panel, sticky tape, and digitizer for 15 bucks. However after it was reassembled (everything worked perfectly then) it has started to act funny, in that the screen will become randomly unresponsive. If I press the top power button to shut the screen off, and then turn it right back on, it will work perfectly. I have no idea what's wrong. And I've tried wiping and restoring the phone and resetting it. Any help?
