I have an Ipad 4, a couple months ago the screen broke I bought a new one paid around 20.00 dollars on ebay. Replaced it myself worked great for about 1 month then noticed certain parts would not respond would go crazy sometimes opening apps typing by itself. I could turn if off and back on it would be ok. Now the touch screen does not respond at all. Do you think I got a cheap screen and another better screen would fix the problem. I have tried everything I can. I've taken the screen out checked connections restarted nothing works. Do you think another screen would solve the problems?
