Samsung will begin rolling out Android 6.0 Marshmallow next month, according to a new update schedule. The Galaxy S6 series and the Galaxy Note 5 will be the first to get the upgrade, followed by the Galaxy Note 4 and Galaxy Note Edge, and the Galaxy S5.

The leaked roadmap, which was obtained by MobiPicker, isn’t the first we’ve seen for Marshmallow — but it is allegedly Samsung’s latest. Unfortunately, it all but confirms the South Korean company won’t be rolling out any Marshmallow upgrades this month.

Samsung is planning to make Google’s latest software available next month, though, and if you have one of its latest devices, you should be first in line to get one. The Galaxy Note 5 and the Galaxy S6 edge+ are first on the list for a February upgrade.

The rest of the handsets in the Galaxy S6 series could also get an update in February, but may have to wait until March. Those with a Galaxy S5, Galaxy Note 4, or Galaxy Note Edge will get theirs in either March or April.

Some Galaxy S5 and Galaxy Note 4 owners have received a Marshmallow upgrade already; Samsung has accidentally made the software available prematurely to a very small number of users. It has also begun beta testing it on the Galaxy S6 and S6 edge.

It should be noted, however, that upgrade schedules like this one pop up all the time, and often turn out to be inaccurate. Take this one with a pinch of salt for now, then.
