personally, i didn't encounter any ground breaking bugs. Don't know why it's not publicly available. Few annoying bugs: 1) some issues with brightness (minimum is just a black screen) 2) if you take a photo in portrait view it is being saved in landscape view oh, and some third party apps from store are note optimized for fullhd Bottom line is that after almost a month of using it i didn't have to restart it once. Everything works fast and fluent.
