this is my second Razr Maxx. i returned the first one due to it having a faulty battery. Now this one is fine but there is one problem, when i slide my finger left and right, the screen is rough and is not as smooth as my previous Maxx. i really don't know how to explain this but seems no one has the same problem as me. i don't know what to do, i do not have a screen protector on and i starting to regret getting the Maxx also because of the constant hiccups and freezing on it( i already factory reset it 2 times). Can you guys help me?
