Sony Ericsson's Xperia Arc successor looks to have made its first appearance on the world stage today, albeit without the company's approval. Leaked shots of a device codenamed LT26i have appeared on iAndroid, showing a magnificent 1280 x 720 resolution and a pixel density of over 340dpi. We're told this is a 4.3-inch panel, much like the newly announced HTC Rezound, and person in possession of the phone reports it feels incredibly responsive and runs very smoothly. He also suggests this is the recently rumored Nozomi and that it runs on a 1.5GHz dual-core processor.

A front-facing camera is apparent to see in the pictures, along with a thin strip of LED lights adorning the bottom of the phone. We can't say we're thrilled about the latter, but we may be able to get over it if the phone's performance lives up to this early intel. Above the glittering lights, you'll see Android 2.3, decorated with the familiar skin that Sony Ericsson has applied to all of its 2011 Xperia handsets. The Arc that this Nozomi smartphone looks set to replace was announced at CES 2011, so it's not unreasonable to expect that the new flagship for the company would also be making its official debut at the Las Vegas convention. CES 2012 is coming up in early January next year, so we shouldn't prejudge what we're seeing here. Sony Ericsson may be able to squeeze Ice Cream Sandwich onto the Nozomi before it makes its way to retail. Then again, there are some (very thin) Android physical keys on this handset, so it's prepared to run with Gingerbread if ICS isn't ready in time.

Finally, a Quadrant score of somewhere around 1,800 is shown in the pictures, which you may consider to be abnormally low for a dual-core device. That's mostly a limitation of Quadrant's own making. The benchmark runs its graphical tests at each phone's native resolution, so these big hulking 720p phones that are now starting to make their way out will appear a lot less powerful than they actually are.
