Why does my Iphone 5c front camera not work?

I recently downloaded the IOS 9 beta onto my phone. It was very glitchy and then the 9.3 version came out. I installed that and my front facing camera doesn't work. I hit the button to switch cameras and it says it flipped but still shows the back camera view. Two days ago i uninstalled IOS 9.3 back to IOS 8.4 hoping it would fix it. It didn't. It also doesn't work while using facetime, or front camera snapchat. My screen isn't cracked and I don't have any clue what the problem could be.

You are running a beta so who knows. Thats the risk you take with that.
