Samsung has quietly launched its slimmest smartphone ever in China. The Galaxy A8 isn't a spec-monster, but it's certainly a design feat for a company that gets criticized a lot on that front. The all-metal body is just 5.9mm thin, weighs a mere 151 grams (5.3 oz) and has a bezel size that you can basically round down to zero. The internals are still good enough to fight any mid-range device: a 5.7-inch 1080p OLED display, 8-core Snapdragon 615 chip, a 16-megapixel f/2.2 rear/5-megapixel wide-angle f/1.9 front camera and 2GB of RAM. Despite the size, Samsung managed to squeeze in a generous 3,050mAh battery that's larger than the Galaxy S6's.
