IPhone 4 front camera is not working
I'm using an iPhone 4 with iOS 6.0.1.
So one day, I was using the camera using the back camera. It is working 100% fine. Now, I want to switch to the front camera. And you know what happened? It froze! It is not responding! What should I do? I tried resetting it, I tried restoring it to factory settings, I tried other camera apps, and the warranty has expired! I'm not rich, so don't tell me to buy another one.
