Camara Problem Iphone 4S

Hi,

Im new here so, greetings from the Dominican Republic.

I bought my iPhone 4S about a year ago, so that means that i have no warranty.

I have a problem on my camera. Sometimes the camera works but when i shake the iPhone or move it a little bit the screen turn half purple and the other half frozen on the object i was going to shoot the photo. Other times the shutter won't open and other times the screen is all black.

Any help on what i should do?

Many thanks.
