I have a Samsung S3 and I really like the camera.
Heck, I liked the camera in my Samsung S (the first one).
Most of the good smartphones today take good enough pictures for most people that there is no need for them to ever own a dedicated camera again.
I have a very good 4/3 camera that takes marginally better pictures than any smart phone. I also have many lenses for it, some dating back to the 1950’s thanks to cheap adapters. But my G3 does such a danged good job, and is always there, that about 90% of the photos I take now are with my phone. And it is the first one I’ve had that has such good photo editing software that I use it on every single picture I save.
My hobby is photography and I’ve been into it since I was the high school newspaper photographer in 1970. We have a saying: The best camera to use for a photo is the one you have on you.
