over the weekend my girlfriend dropped her iPhone 5c yet again. awhile ago when she dropped it one of the corners had popped out and we snapped it back in, a click of the screen developed and it was fixed by apple. Now again the same corner (top left) it popped out when dropped but this time much further, and a tiny bit in the corner where you see your signal seems cracked. Its not like a normal crack where the screen will actually crack but in the corner it seemed a less lit up portion like maybe a digitizer and the glass separated. I wasn't sure but the screen still works perfectly. Today, she dropped it again (happens a lot) and it seemed to fix itself to where the screen is back to normal. Does anyone have a clue on what exactly had happened?
