My iPhone 5s is acting all funny?

My camera doesn't work, not even for any apps like snapchat or vine. But it works for FaceTime. And I'll sign into YouTube and Tinder all the time then when I exit out of the app and open it again, it signs me out then I have to sign back in. Wtf. What's wrong? I tried everything already (closing apps, restarting it)

Thats odd, I would just connect to itunes and reset it back to factory to start it over.

  • Where can I find cool and funny iPhone 5 cases? I've actually seen lots of bloggers posting those funny and cute cases… Like shapes of ears, food, nose, a cup etc. But where do they actually buy them? Please give me a link ^^
  • Where can I find cheap funny looking iphone 4 cases? I want like gameboy cases or chocolate bar looking cases or cute little looking cases like makeup kit looking cases or cases that look like realisticly looking real things etc would rather not look on ebay because i hate having to bid unless they have cheap shipping and/or buy now options for someone who sells them in quantities and amazon has cool ones but i would rather not have to spend 20 dollars + on a phone case. Any cheap LEGIT/RELIABLE websites would be a wonderful help!
  • What funny things can I make Siri say? Well I have an iPhone 4S with Siri and I was wondering if anyone knows what funny things I can say to it
  • My iPhone keeps making a funny noise? It's sort of lile a 'ping' sound effect, and it happens about 2-3 times a day but its never at the same times. Some days it doesn't even make the noise (RELIEF! Lol) It's so random, and I'm always terrified when it happens. I think it's trying to tell me it's overheatin or something, so I've sent it to my local Apple expert. I just want to know what other people think of it before I get it back.
