This is Acer's new giganta-smartphone, the Liquid S2, and it's sitting on a fairly impressive secret: it's the world's first phone to pack a 4K-capable video camera.
Shout "overkill" or "progress", whichever you prefer, but either way it's an impressive feat squeezing such a sensor into the body of a phone. Not that this is an Android handset without some space inside: its 6-inch screen gave Acer plenty of room to play with.
Lurking within its body is a 13-megapixel rear camera with LED ring flash, a 2MP front camera (itself capable of 1080p video), a Snapdragon 800 chip clocked at 2.2GHz, 2GB of RAM, 3300mAh battery and 4G LTE connectivity.
The handset will initially go on sale in Europe at the end of October, although it's not clear when it will make it to our shores. Pricing details are currently to be confirmed. [Engadget]
