got my note2 yesterday.
i think they made the lock screen (number pin) keyboard a bit wide.
Check in the options if you can set it to one handed mode so it isn't as wide.
I think I will sell my s3 once I get a replacement and buy this !
I came from an S3 to this - bigger screen, more ram, higher clocked cpu, monster battery and split screen mode for apps. Good upgrade imo.
