http://forums.androidcentral.com – This is interesting... I got my Note 2 ( GT-N7105 ) from HK and it has and can do multi-screen... This am I was with my cousin and he has a Note 2 from North America and he told me he doesnt have multi-screen function. Strange... so are there variations of Note 2 for specific world regions? or will this be an OS upgrading issue?? Just curious... (HowTos)
