A few weeks ago I dropped my phone and of course the screen cracked. Since it cracked my screen would not let me do much, it was very touchy. If I wanted to send a text message it would all of a sudden go back to the main screen. So I ordered a digitizer and got it installed. It worked okay at first but now its doing the same thing as before I replaced it. Can anyone please tell me whats wrong and if there is anything I can do?
