The HTC 606w, an unannounced Android smartphone with an UltraPixel camera, has been leaked gaining regulatory approval in China. The midrange device is said to be a “spiffed up version of the HTC First” — the first smartphone with Facebook Home.

The HTC 606w, which is unlikely to be its final name, features a 4.3-inch 720p display with 342 pixels-per-inch, and a 1.2GHz dual-core processor. It also packs 2GB of RAM, 16GB of internal storage, and a 1,700 mAh battery. On the front there’s a 1.6-megapixel camera, but things get a little more interesting on the back where you’ll find one of HTC’s new UltraPixel sensors.

This technology made its debut on the impressive HTC One earlier this year, and you can expect it to reach more HTC devices throughout 2013. UltraPixel cameras absorb around three times more light than traditional smartphone cameras, and promise sharper photos and significantly better performance in low-light environments.

The HTC 606w is said to be running Android 4.1.2 Jelly Bean with the new Sense 5 user interface. It’s already been given regulatory approval in China, according to PhoneArena, so it may get its grand unveiling there soon. It’s unclear at this point where the device might be available after that, but we’ll keep our eyes peeled and let you know as soon as we get more information.
