Just yesterday we shared a rumor that a Hungarian Samsung Galaxy Note 4 received Android 6.0/Marshmallow already. Despite our skepticism, a new video popped up today showing off Marshmallow on the Galaxy Note 4, suggesting that the previous rumor was for real.
The video shows off a new Air Command menu, new icons, and the screen-off memo feature from the Galaxy Note 5. It's still possible what we see above is a test build and not the final build. We will keep an eye out for any further corroboration. You can check out the video in the thread below.
