Main camera only working in burst mode.

[Spike Spiegel1]

a short while back my AT&T 820 auto updated to Cyan and after it did when i try to take a picture with the main camera in normal mode it just freezes like its about to save the pic stays that way and eventually the app crashes,its the same thing if i try to take video. After a few days I noticed that it will only take a picture is in the low quality burst mode and i also have no issues when using the front camera as it will record videos and take pictures with no problem. I have tried resetting and reinstalling the OS with nokia software updater and it stays the same. Have also looked for ways to roll back the OS with no luck and it seems Denim will never be released for my phone so i will probably end up throwing it out and never buying a Lumia again. Any feed back or suggestions would be greatly appreciated.
