Default [Q] Phone Problems

Good Evening,

I have a few problems with my Sony Ericsson Xperia Play (R800i) which I have listed below. I hope someone can help me.
  1. When I press the Camera it says "Camera Error" "Cannot connect to Camera".
  2. My phone will only charge while it is turned off. I have tried using different chargers and stuff.

Can I get some help to solve these problems?
