I agree the front camera is pretty bad... I came from the HTC DNA, and I feel it was better too.. my wife's iPhone 5 ffc is way better than my LG G2..
I don't use it that much so isn't really a big deal, but would have liked better quality..
Rear camera I am happy with.. like with any cell phone camera there are times I am impressed and times I am disappointed, but overall I am happy with the G2 rear camera.
