This is the first phone my GF and folks have had that they have not threatened to go back to Apple devices (grandfathered unlimited data which we use extensively with AT&T on android, switched from iphone 3g unlimited data to android unlimited data, so we cant go back to apple grandfathered unlimited data as far as i have been told). GF had an older Android and iPhone 6 for work; folks had an S3; now S7 Active. None of them care about root/ROM/tweaking etc; all they care about is stability, usefulness, camera, and battery life.
I have ALWAYS screwed with my phones (...and cars, computers, cameras, bikes; anything really); this is the first one that out of the box i was happy with. Yeah, i tweaked it, but its been very impressive, even totally stock. We've soaked ours with no issues, repeatedly. GF and folks love theirs; even my dad, and he DESPISES technology.
Technical camera review/synopsis below.
S7, S7 Edge, and S7 Active cameras have comparable OIS (optical stabilization) to lense stabilization found within the venerable $700 Nikon 18-200 VR f3.5-5.6 (Mk-II) and $650 Nikon VR 70-300 f4-5.6 with VR (Vibration Reduction, same thing as OIS). Thing is, with Nikon and Canon DSLR's, you have to buy specific optically stabilized lenses (typically zoom lenses), with the S7 series, its built in and always active. Granted, it has no optical zoom or interchangeable lenses (but its a fixed lens camera... on a PHONE...). Also, in RAW+Jpeg mode (available in Pro mode in Camera app), 12.5 stops of DR at ISO 400 which is comparable to the 2009 Nikon D300 pro/prosumer DSLR i drag around with me daily that was $1700 new, also at 400 ISO. I built a business and a career around that camera as well as ancient Canon XH-A1 tape-based HD footage. And i can now replicate the same results, with a MOBILE PHONE. Thats pretty impressive. AF tracking works JUST as well as the Nikon MultiCAM AF-3500DX in my 'drug-everywhere' Nikon D300 pro/prosumer DSLR with 51 point AF 3D tracking, and with a wider spectrum of available focus and focus tracking points. WORLDS better than the XH-A1 videocams i shot with, equipped with 35mm adapters, SLR lenses, etc etc.
Also, D300 is 12.3mp; S7 series is 12mp... Same difference. In RAW there is no sharpening or added BS; just raw data recorded, and i can view/edit them lightly in Adobe Lightroom on the fly, export as jpeg etc.
For what it is, it works incredibly well. For what it isn't, i can't complain; i have a D300 and D4s and a bag of crazy expensive lenses, as well as Blackmagic Design cameras that shoot RAW video and accept my Nikon lenses and OIS Panasonic Lumix 12-25 f2.8 lens that i use for work or whenever i want.
With such a tiny sensor, the perspective is always way off, i have basically no depth of field to play with, zoom is a total joke as its digital, and creatively i cannot get any distant shots remotely close to how i would like them, but thats a physical limitation. It also allows me to take RAW shots in places and circumstances i would not DARE risk taking $1400-$5000 worth of camera/lens combo's for a quick candid shot, so for that its awesome; lets me take shots i would otherwise have passed up so as not to risk expensive gear, and i have the same fidelity as a pro/prosumer SLR. And its a PHONE, that within its limitations, competes with a flagship DSLR (albeit from years past) with ease.
I would NEVER take any of my DSLR's, m4/3 RAW Blackmagic Design bodies that shoot RAW digital film (no phone shoots RAW video, YET...), or expensive lenses to the places ive already taken the S7 Active.
For me, its been great; dunked it, bonked it, swam with it, flipped my kayak with it, filmed under and over water with it; bitrate in video and fidelity in HDR is close enough to old AVCHD and HDV tapes (analog compressed vs digital compressed), and most of all, i am unafraid to USE it in places i would NEVER risk my precious work gear.
