Be very careful of what you wish for. KitKat 4.4 has completely changed the way it uses external SD cards. Many apps are broken and can't access the external SD cards. I have the Note tablet and now apps can no longer write to the external card. I use my tablet like a PC and need this functionality everyday. Totally sucks. I hope the KitKat update to the Note 3 phone is not the same or at least they will provide an alternative. Beware people! See detailed explaination below. FYI, like most updates, you cannot DOWNGRADE. No going back!!!
