This is in line with a report from last month in which an alleged Marshmallow roadmap for Samsung was leaked. According to the roadmap, it suggested that the Galaxy Note 5 will be receiving its Marshmallow update in February, and it looks like it was right on the money. While Marshmallow has been out for a while now, we suppose better late than never.
As for the other parts of the world, it is possible that you might get your update later. However with the update being rolled out as we speak, we suppose it is only a matter of time before it makes its way to your region. Unfortunately for those who might have bought the carrier versions of the phone, your update could take longer.
This is because carrier-tied phones tend to receive their updates later due to additional checks and approvals. After all should anything go wrong, carriers will probably receive the brunt of the complaints and by checking and approving it, at least they remain in the know. Either way we’ll be keeping our eyes peeled.
