Let's be honest here: The previous iterations of the Nexus line have been lackluster at best as far as the camera is concerned. This launch, with the marketing approach firmly geared towards the camera, they released the device with yet again a lackluster camera. This time, however, the hardware was more than capable of producing good photos. In fact, it's capable of producing some excellent photos. What happened was sites like the Verge put a very negative stigma on the camera, almost as if drawing on how the Nexus line has been before. The same thing with the battery.
As time has gone on, specifically with the update, there's really no disputing that the camera is pretty good. Is it the best on a smartphone? No, but it's a more than capable shooter that I'm comfortable getting on a phone that's $349 off contract. Actually, it exceeds my expectations for a camera on a phone at this price point. It's unfortunate that they released the camera with some glaring software issues as all it's done has given critics and people who have no idea what the hell they're talking about reason to say the camera "sucks".
So if anyone is reading this, post-update, the camera doesn't suck. Far from it. I don't care what you've read review-wise or what your friend without the update claims; it's good and you should be more than happy with it.
