Things that don't work, for me, at least: - I could not configure fingerprints to unlock the phone: every time I try that, despite repeatedly pressing my finger on the reader, nothing really happens and the application ends up with a time out message. - The camera works, but it kind of crashed on me in the middle of a photo session (black screen, UI unresponsive). The picture quality overall is a bit underwhelming, but I guess I am spoiled by Android and the cameras available there.
