I took my phone to a repair shop and they replaced my screen for 120 and now the screen keeps freezing and the only way that it unlocks is so do a soft reset. It locks up at least 20 times a day. It wasn't doing this before the screen replacement. Do you know if it is the same problem. When it freezes no buttons work. The only way to unfreeze it is to hold both bottens down and do a soft reset. The guy said that the problem is the phone and not the screen replacement.
