My front iPhone 5 (iOS 8.4) camera doesn't work?

I open the app and when I try to use the front camera it's very blurry (can't see anything at all) and it freezes. I tried getting a new camera installed and that didn't help at all. The back camera works perfectly fine.

You need to visit either the Apple Store near you or your service provider.

Hopefully you had the foresight to take out insurance on the mobile.
