What’s available at this time is a public beta test that aims to improve the quality of Marshmallow by collecting user feedback. The S6 is one of the first devices eligible to participate in this program. There are a few stipulations though—it’s only available in South Korea and the UK. If you meet those requirements, you can take part in the beta test by creating a Samsung account, downloading the Galaxy Care app, and completing the Galaxy Beta Program registration.

Even if you don’t happen to live in South Korea or in the UK, the Marshmallow update is still right around the corner for the rest of us. Keep in mind that if you have a rooted phone, updates can interfere with the root, or vice versa. It is also possible to experience no issues at all. Additionally, having a rooted phone may enable you to receive the Marshmallow update even faster—check out Method 3 about custom ROMs.

Method 1: Update Over-the-Air

This method requires a little wait time. It does depend on when your carrier releases the Marshmallow update, but the leaked estimate is January. Once they do release it, you will find the following OTA method very easy to complete.

1. Ensure that you have a stable Wi-Fi connection.

  • If your Wi-Fi connection is unreliable, it might be best to use Methods 2 or 3 instead.

There’s a version of Smart Switch available for both mobile devices and PCs, and for both Windows and Macs. You will want to backup your data prior to the update, but luckily Samsung Smart Switch affords you that option as well.

Method 4: Update by Installing CyanogenMod 13 with Marshmallow (For Rooted Devices with a Custom Recovery)

If you can’t stand the suspense, installing CyanogenMod 13 is one way that you can get Marshmallow ahead of the rest. Keep in mind, however, that this is a custom ROM that was only recently released. Therefore, you will be taking on the risk of installing a custom ROM, which can void the warranty or at worst, brick your phone. You could also encounter some bugs until the release of a more stable build.

WARNING: This is an unofficial, third-party build! Currently, the S6 is not supported by CyanogenMod. Users have reported possible issues with the camera, GPS, 3D graphics, and more.

  • Navigate to the Gapps zip file that you transferred to your Samsung in Step 5.

If you go with the CyanogenMod ROM you will have the advantage of built-in battery improvement due to a lack of bloatware; nearly doubled by the battery advantage that Marshmallow brings. However, since there are only a few devices on which CyanogenMod 13 is officially available to use, you might have to deal with some disadvantages as well. It is a trade-off. But, it is currently the only way to get Marshmallow on the Samsung S6.

Waiting on OTA updates is not only the easiest option but is also the safest. It doesn’t provide you with immediate gratification, but January is near. Samsung Smart Switch is also very easy to use and is also capable of transferring, backing up, and restoring data. Odin is your best bet for a rooted phone once an official update is released, especially if you rooted using a custom recovery.
