My iPhone 5 is receiving calls and texts but the screen is UNRESPONSIVE

Recently someone lightly bumped into my iPhone and it suddenly started fading to black from the upper right corner. I can still hear everything coming into my phone like messages, alarms, calls, etc but THE SCREEN WON't WORK AND I CAN't PRESS ANYTHING like swiping the bottom to answer calls and even siri doesn't work now.

Please don't tell me to do a hard reset because I've done that a million times and it had 94% battery when it died.

I can't sync anything to iTunes cause they require me to enter my password WHICH I CAN't! I have really important pictures in there that I really need to sync! Also, all i asked apple to do was switch screens for me but then they threatened me that they would void my warranty.oh Apple, i'm no longer impressed.

It seems your screen is broken. Go to apple store or some place they repair phones to replace the screen.
