Finally, as per some users, Samsung Galaxy Note 4 has started receiving Android 6.0 Marshmallow in some regions. As per the details, Galaxy Note 4 has got firmware build (version N910FXXU1DOL3X) after update.
It looks quite strange that Samsung is rolling out Android 6.0 Marshmallow update to Galaxy Note 4 before the 2015 lineup. Some are saying that Samsung has pushed update mistakenly but maybe Samsung is giving some fantasy to the ill treated Note 4 users who are lurking for Lollipop Update on their devices.
The above screenshot was taken by source, Napidroid Editor in Hungary.
After update, there are many changes that got noticed beside the usual ANdroid 6.0 Marshmallow features. Namely, Samsung Galaxy Note 4 has got Air Command, new icons, faster UI, smoother animations and many more changes are gifted.
We can say may be Smasung just want to test this build and later on  rollout worldwide.
So anyone here have received the update?
