Try Lgcamera for better front cam video and way better audio,also for 4.1+ roms topic

You can choose your audio bitrate and this improves a lot your audio,also the video quality improves too a lot I choose 20mbits bitrate(don't know if I can choose more with class 10 card)and the result looks almost hd!Unfortunately the picture quality of the front camera remains the same .maybe someone could do a fix? You can try it also with your custom non ICS roms I think it's a great app
