Iphone 4s is going crazy, why?

This is just happening today. My phone will be completely fine and then after 5 minutes a black screen with white lines will appear and then my phone will shut off and then turn back on again. Repeating over and over. What is happening, and does anyone know what this means or how i can fix it?

Well thats the thing about Iphones wen a new one comes out the old one shuts down. For example the iphone 5 just came out so they want every one to spend more money on that so they shut the 4s down. If i were you id get a samsung, or a soney.

hope this helped lol

Restore it through iTunes. That should fix the issue. Don't believe what Megan said. First of all, the iPhone 5S just came out not the 5. Second of all according to Megan, since the 5S just came out, then they would be shutting down the iPhone 5. I have the iPhone 5 and it works fine. Megan doesn't know jack about iPhones. Can't even spell "Sony" right…

The same thing happens to mine
I brought it to the apple store and they fixed it i don't know how though i recommend bring it to the apple store
