The latest images of the already extensively-leaked Sony Xperia U show a comparison with its big brother, the Xperia S. The Xperia U -- also known by its model number, ST25i, or its codename, 'Kumquat' -- is expected to be Sony's principal mid-range smartphone for 2012. Today's images mostly confirm what we already know -- that the Xperia U will share a number of design cues with the Xperia S, most notably the transparent notification bar at the bottom of the device.
Spec-wise, the Xperia U is rumored to pack a 1GHz dual-core CPU, a 3.5-inch qHD or WVGA display and 512MB of RAM, with a 5MP rear camera. Like the Xperia S, it'll run Android 2.3 Gingerbread with the latest Xperia UI, and we'd expect a bump up to Android 4.0 soon after release.
We're expecting to see the Xperia U unveiled at Sony's Mobile World Congress press conference next Sunday in Barcelona. In the meantime, you can find more photos after the jump.
