I got my Lumia 830 from AT&T last week, first Windows phone (switched from iOS), and love it so far! I haven't noticed any of the issues mentioned so far, except that the Jedi hand wave on the glance screen doesn't work very well--but then, I didn't know it was supposed to be better! I figured it just wasn't able to respond to a gesture like that. Now I know to keep trying.
One oddity: every time I plug in the charger, it tells me that the phone is charging slowly, and that I should use the charger that came with the phone. The thing is, it IS the charger that came with the phone! Anybody have any insights on this?
GREAT forum by the way. Finding lots of good info from all of you, thanks!
