for me it came with a bug. upon charging while device was off I woke up to find that when I unplugged and held the power button nothing happened. when I tapped it, it told me swipe to unlock and turns out my phone was on for 4hrs meaning during 1hr of chrging it booted up. I did the math. Also upon pressing the status bar, it showed USB charging only while not connected at all, long txt msgs don't show up due to a character limit I guess. I never had issues with my n900 but now I got a couple.
