My IPhone screen is not responding?

My mom was trying to take my phone so I was grabbing it and pulling it an away from her and when I got it back the screen was frozen and I couldn't go back to the home screen or even turn it off. After a while the whole screen turned black and now I can't do anything on it.

Visit your local apple store or call apple care.

contact details can be found from apple.com and choose your region.

You should take it to where you got it (verizon, at&t Sprint etc.) and let them know the situation. If you have insurance then you should be able to get another one or send that one in for repairs. It sounds like something happened internally with the hardware.

When that happened to me, I just plugged it into the charger and left it. Eventually it recalibrated itself. Give it a couple hrs.

Try to put it into DFU mode. To do this, hold the power button for 2 seconds, hold the home button WITHOUT releasing the power button for 10 seconds, then release the power button while holding the home button and hold it for 15 more seconds then let go. In the 15 seconds part, the Apple logo will turn on, but finish the 15 seconds. Plug it into the computer and you can try the rest by yourself. If this doesn't work, hold the home button while connecting to the USB cable and open iTunes. This will do something, but I forgot what it did. It doesn't anything bad though.

Stop being a spoiled brat and when your mom trys taking your phone away that she probably bought and pays for let her take it and don't fight back.
