Samsung Devices Which WIll Receive Android 6.0 Marshmallow
The following list of devices will likely be getting an update from the manufacturer to Android 6.0 Marshmallow. This will be the Samsung-modified version of the software, not a "vanilla" version as would be delivered to a Nexus device. To our knowledge this is a fully exhaustive list of Samsung devices set to receive this update FOR NOW - there may be more in the future.
This list does not include the Samsung Galaxy S5 or original Galaxy Note Edge, but we wouldn't rule these very capable devices out just yet. Samsung generally updates devices at least year out from release, especially if they're hero mobile machines like the Galaxy S series.
For more information on the Android 6.0 Marshmallow update, have a peek at our guide on Android 6.0 Marshmallow: What's Hot and What's Not. You'll also find the Android Marshmallow wallpaper gallery helpful if you've got a device that's still several months out from an update.
We should wait and see what Samsung does in next few months.
