I just bought a used unlocked Note 3 a couple of weeks ago. I have just come to realize that it is running 4.4. Is this Kit Kat? How would this get on the phone if it isn't even released? Can it be removed and replaced with Jelly Bean? I am not a phone tweaker and Like my electronics to be stock and follow proper channels for updates. If I can and elect to back peddle the OS could I be opening a whole new can of worms?
