My title is pretty self explanatory. I came home last night and my phone fell out of my pocket while I was at my computer and hit the floor. Drop height about 2 feet. I've had my phone fall further before and onto concrete so I was like happens. I pick it up, no broken glass, so i was like whew okay. I go to use it the screen stays black. I can use all the buttons, I can even unlock it if i hit the home button. I'm not sure what I should do!!
