The S6 is hands down the best camera out there. Samsung has focused on image quality, while taking a break from megapixel inflation. An infrared sensor helps the camera control lighting conditions for better white balance, or neutral color cast. That explains the mostly accurate colors, especially in low-light images. A 30 percent larger aperture over the Galaxy S5’s (f/1.9 vs. f/2.2) also helped produce brighter low-light images at faster shutter speeds. Combined with optical image stabilization, the S6 delivered very sharp photos in dim lighting. The camera’s phase-detection autofocus is nearly as quick as the iPhone 6 Plus’s, and face recognition is dependable. Focus tracking allows the camera to keep your subject sharp while you’re shooting video or a burst of photos. Other upgrades, including a 0.7-second startup time and a 5-MP, f/1.9 front cam, make the Galaxy S6 phone camera the one to beat.
