I don't know what's wrong with my iPhone 5?

I recently got my iPhone 5 fixed as I accidentally dropped it and smashed the screen. It has been working completely fine until just now when a dark purple colour wiped across the screen and turned the whole phone off before restarting itself. It just happened again as I'm typing this.

Any advice?

Added (1). It keeps on happening now whenever I try to use the phone. Also, the battery is constantly jumping up and down.

Solution: don't get an iPhone

  • People that buy iphones don't know anything about technology did you know that? Like my friend just brought iphone and I asked him if it has 4g late he said what's that? Then I asked how fast is the processor like 1.2 dual people buy them because its more mainstream and because their friends have iPhones Samsung is way better based on specs and technology the iPhone 4s and 4 processors are very slow
  • My iphone is broken and I don't know what's wrong with it? First of all the front and back is cracked which I know how but can someone tell me what's wrong with the screen because when I turn it on or go onto an app or something you can see faded black lines in the background which are not suppose to be there. It is an iphone 4s btw. Also it turns off by itself sometimes. Please could someone tell me what's wrong and how much it costs to fix?

  • Is there something wrong with my phone or is there something wrong with my mom's phone? Ok so when I attempt to call my mom, it doesn't ring it just goes straight to voicemail but doesn't show on my mom's phone that she had a missed called. My messages won't go through either, but her calls and messages come through to me. We both have iPhones and they are both on. I can text everyone else, call everyone else but her.
