If you're drawn to Android phones, welcome to an embarrassment of riches. There are so many great phones that it's hard to settle on one for long, because another amazing Android phone comes along every 12 minutes.
The new greatest Android handset of all is the Samsung Galaxy S7 Edge. Or maybe it's that phone's sibling, the less-curvy and smaller Galaxy S7. Either way, you're getting a tremendous combination of photographic firepower, in-hand comfort, build quality, water resistance, processing, and pragmatism. They're super-versatile, and that's before you get to the part where they're the cornerstones of an excellent VR platform.
But above all, the new Galaxy flagships make one thing clear: Smartphone cameras have transcended their station as convenient "good enough" replacements for dedicated point-and-shoots. The S7 cameras are better than many point-and-shoot cameras. Like a lot of modern smartphones, their optically stabilized cameras shoot 4K and hyperlapse video, and they have manual exposure controls. But these cameras also rethink how and where we use phones to make pictures. They capture more detail and color in the dark, thanks to a trinity of attributes.
First, the wide-open f/1.7 aperture helps harness light, allowing the camera to use faster shutter speeds in the dark and capture a shallow depth of field. Second, Samsung decreased the pixel density of the sensor, spreading 12 megapixels across an imager that's larger than the last generation's 16-megapixel sensors. A bigger sensor with bigger pixels also helps capture detail in low light.
But the most notable feature is the new autofocus system. Each one of the 12 million or so pixels serves a dual purpose: to collect light and to drive the camera's phase-detection AF. Compared to common contrast-detection autofocus systems, phase detection is faster and more effective in low light. A contrast-detection system searches in and out for focus—a serious challenge for low-light and fast-action shots. A good phase-detection system simply pops into focus.
