  • Tilt feature on my new iPhone 5 is not working properly? I just bought a new iPhone 5 today, but the tilt is being really weird. I tried to play doodle jump but the iPhone acts like I'm constantly titling to the right side. But I'm not. And I do have experience with apple products, so I know how to work the iPhone, but I just can't seem to figure out what's wrong. I had also put a Lifeproof case on it, could that be affecting the phone?
  • Sound on my iPhone not working properly? I have an iPhone 4s and the sound will work when I get a call or a message but it won't work when I try to watch snapchats or vine videos? I can listen to them with headphones in but it won't work without headphones, does anyone know how to fix this?

  • IPhone speakers not working properly? I dropped my phone in a bowl of ice cream a few weeks ago therefore getting icecream in my speakers at the bottom of my iPhone, and when I play music, it only comes out of the speaker on the right side; not the left. I just wanted to know if there's any way to fix this? Whether it is at home or taken to a professional? Basically I want to know whether my phone speaker is fixable at all in any way.
