Well good luck with the note.
I never had any issues out of my g3. Battery is great, no overheating, no random reboots, no major lagging as a matter of fact no lag at all mostly a stutter here and there in the app drawer from time to time. Been using the stock lg launcher since I got the phone and everything for me has been fluid.....
Lol then I see you made a post saying the phone was fast and no problems out of it........
TO MANY TO LIST!!! LOL
IF I HELPED YOU WITH ANYTHING HIT THAT THANKS BUTTON.......
