IPhone screen does not work?

I dropped my phone and now nothing shows up on the screen! It still works, I can still unlock it because I memorized where the numbers are placed but I just can't see anything! When I press the lock button to unlock it, the screen lights up but it still shows just black.

You have to replace the digitizer of he phone if you know how you can buy it on amazon for around $60 if you don't then take it to apple they charge around $140

Hold down the home and power button for about 1 minute the leave it for a second and turn it back on. Hope i helped

Alright there's 3 things you can do and this will be your best help:
1. Hold down the home(circle button) and wake/sleep button(up top) for 30 seconds. Your iphone will restart after 1-2 min.
2. Call customer service and they will actually reset your phone from their company.
3. If its under a year of having the phone they give you a (free!) one. All you need to do it contact them and they'll send you another phone. Then all you need to do it send your broken one back to them.
HOPE I HELPED GOOD LUCK
