For now we wouldn't get too excited by this rumor, but supposedly the Samsung Galaxy Note 4 is now receiving the Android 6.0 Marshmallow update. The reason we wouldn't read too much into this is that the rumor indicated it's getting the update in Hungary.
While it is not unheard of for Samsung (or any OEM) to start rolling out big updates in smaller countries first, previous intel gave us a solid roadmap for Marshmallow to roll out to various Samsung devices, and this "intel" doesn't fit that roadmap. Still, Samsung has been known to surprise us with plan changes in the past, so we felt the need to share this rumor with you.
If it is rolling out in Hungary, it probably won't be too long before it starts to push out globally.
