According to a new report from Napdroid, Samsung are due to update a number of its already announced devices to the new Android 6.0 Marshmallow update over the next few months.
According to the site the biggest of these devices will be the Galaxy Note 4, which comes from a claim that one of their editors received a Note 4 device with Marshmallow in Hungary.
Also according to the site, the Note 4 will get a number of changes with this update, with changes to the interface and a range of new features, with an updated Air Command menu and more.
We don\t quite know if this update was a mistake from Samsung, or if the company was officially rolling it out.
However according to rumours devices including the Galaxy Note 5, Galaxy S6, Galaxy S6 Edge and Samsung Galaxy Edge+ will get the Marshmallow update before the Note4, but they do claim the Note 4 will get such an update later this year.
We will let you know more when we hear more.
