Hi guys...i've had my N1 for 2 weeks now and i've been having a problem ever since i got it....when i make a call and the conversation has ended the device takes like 2 minutes for the screen to come back on.....i press every button and it just wont come on...sometimes i have to plug in the charger and plug it out to wake it up and worst case..remove the battery...it just sleeps forever...is anybody else having this problem? is it a known bug? please help....
