I have had this phone for about one month and can't say enough good things about it. When I bought my first smartphone 2 years ago, I passed on a Samsung for reasons I no longer remember. But almost immediately I began regretting my decision. So when my plan was up, I promptly went to the store and bought the S7.
The battery life is outstanding in "power save" mode. I barely notice that some features are not running in background. I get through the day with power to spare.
The camera is my favorite application on this phone. The shutter lag is almost zero, so action shots of sports and pets are predictable and blur free (see attached "dog in flight"). The colors are true without adjustment. The built-in photo editing tools contain everything most casual photographers could want.
I operate mostly in a wifi environment indoors, but when I'm outside, the 4G kicks in without a hitch.
The fact that we live on a lake makes the waterproof feature a real plus. I've operated the camera while wading neck deep in the water and during a heavy rain. My wet fingers were no problem for the touch screen.
