Let me say that I am not a noob. Although at this moment I am kind of feeling like one. I installed the camera app. It now doesn't work. (as stated in the OP which I should have read thoroughly prior to installing) but now my camera doesn't work at all.
I tried flashing XDABEBB's camera which I use and it still get a FC. In addition I reflashed my cloudy stock rom and still my camera is not working which is really odd. I would think reflashing the rom would definitely fix it. Does anyone have any thoughts about how to fix this.? Also maybe there should be a little more warning in the OP that is perhaps maybe in red or bold stating that the apps do not work and might cause some problems. Again I understand I am at fault and pretty much everything here on XDA is at your own risk but...... Would be helpful when your having a careless moment.
