Situation is this: I took my phone out of my pocket and dropped it from about pocket height on a sort of tiled floor. The screen then became green and had lines. Then the screen just turned off. When I looked for physical damage, all I can see are tiny cracks at the top right of the screen. Everything else works fine (home button, back button, vibration, led, etc.) How would I fix this or do I need to go to a repair shop. Thanks in advance.
Also I have the T-mobile version. I don't know if that matters.
