The rumored Xperia Neo still isn't official -- we think we're probably looking at MWC next week for that -- but there are enough floating around at this point so that they're getting tested pretty thoroughly (or, at least as thoroughly as you can test a pre-production device). The latest tidbit comes via a series of videos and stills that put the phone's 8.1 megapixel sensor through its paces; frankly, they look a little washed out, but it's really common for camera performance to improve by leaps and bounds through firmware updates right up until a phone's commercial release so we don't want to sound the alarm quite yet. My Android Life has also thrown together a quick video walkthrough of the UI, where you see that Sony Ericsson seems to be standardizing on the same experience first seen on the Xperia Arc and later on the Xperia Play -- highly widgetized with a Gingerbread core. All things considered, it seems the Arc's a higher-end device -- but if the price is right, this Neo could win some hearts as well. Follow the break for the UI walkthrough.
