With curved sides and rounded corners, the Find X phone from Oppo looks a lot like the Galaxy X9 but the defining feature of this new Android device is its motorized pop-up camera. When the camera app is closed there’s no sign of a camera anywhere, but when it’s open, out pops a 25-megapixel front-facing camera, 3D facial scanning system, and 16-megapixel + 20-megapixel dual rear camera.
