If previous leaks had us fairly convinced Samsung's Galaxy S 4 Zoom cameraphone was a real device, this latest one has us certain. A Russian website has published what can only be described as a full review of the Zoom, before it's even been officially announced. The camera is said to pack a 16-megapixel sensor, and is capable of 10x optical zoom, achieved by rotating a ring situated around the lens; this ring is also used to launch the camera mode. A piece of glass sits flush with the end of the lens for dust protection. Inside, the Zoom is similar to the S 4 Mini, running a dual-core 1.5GHz Exynos processor, 1.5GB of RAM and eight gigs of internal storage (naturally, there's a microSD slot for boosting that). Facing you is a 4.3-inch 960 x 540 display showing Android 4.2.2 (with a TouchWiz coating, of course), and powering the whole thing is a huge 2,330mAh removable battery. Other specs include a 1.9-megapixel front-facing camera and IR blaster. Connection options include WiFi, Bluetooth 4.0 and NFC, but it doesn't appear that LTE was present on the Russian model.
