Camera picture quality is somewhat decent in good light conditions, but not so good in low light. Video recording has awful audio quality at least for now, looks like software issue though. There has been some quality issues also (sim-card connection loss when pressing the back, random reboots, jammed vibrator), but for most part they have been sorted out with newer HW-revisions. Screen is nowhere near best HD displays on the market and it's difficult to read in bright sunlight. Spare batteries are practically not available at all.

Otherwise I have no complaints with my device, been using it as my main phone since from the beginning. Device was replaced on warranty after vibrator ceased to work, at the same time reboots and sim-card problems disappeared.
