IPhone 5 is acting really weird lately?

I have an iPhone 5. Lately my phone has been acting really weird. I can't send iMessage/texts when I even have good reception and signal, all of my apps crash within 3 seconds of clicking on them, and all my pictures are blurry, even though they we're when I took them. I also can't change my background. Does my phone have a virus, or if not, what's wrong with it & is there a solution?

If you didn't jailbreak it then you don't need to worry about viruses with iphones. Did you drop it? Sounds like you did something to it. Try restoring back to factory (backup first of course).

Sounds like the software is not up to date.

  • Why is my iPhone acting weird after updating it? When I'm using 3G and I search for something on google or try to open a link from my Facebook app, I get a message that says "Response Error. Technical description: 502 Bad Gateway - Response Error, a bad response was received from another proxy server or the destination origin server." What the hell does that mean?

  • Why is my iPhone 4 acting weird with music? So when i go to the gym i listen to music. When i hear a song it fast forwards by itself and skips to the next song and then it pauses, it happens sometimes. Or when i'm listening to a song it presses Voice Control by itself. What is it?
