A 808 pureview hands-on video has been posted on YouTube by Allnokia.ru. The device seems to be running very recent Nokia Belle FP1 firmware dated 12th of April which should be pretty close to the release Firmware as the device is supposed to be launched as early as 27th April in some regions.
The Menu and Homescreen scrolling, Browser prformance, Camera UI and performance are looking more polished and have smoother feel. Browser is really fast in loading heavy Nokia device pages and panning seems to be good.
