New iPhone 3G digitizer, sometimes unresponsive
recently I have had a small digitizer problem (totally unresponsive bottom, small enough to allow unlocking) which I attempted to solve by bying and installing a new one.
Everything seemed fine at first, but after a couple of hours I noticed that sometimes the whole screen stops responding. Judging by the price, it is not an original Apple digitizer, therefore, I think it may be some software issue since simple pushing the sleep button and then unlocking fixes the screen... untill it freezes again.
The problem seems to occur while using an app, rarely while in springboard or while texting.
I have already tried putting the phone apart again and checking the screen connector. It fits the socket just fine, better than the old one actually.
Any thoughts are welcomed, thank you in advance.
Is this a good question?
