Android 6 Marshmallow to the Galaxy S6, though Telus customers have been left out in the cold. The firmware was supposed to have arrived back in early March, but as is so often the case with Android updates, managed to hit a few bumps on its way out.A number of carriers have already rolled out
The Galaxy Note 5 on T-Mobile is also now seeing some long-awaited Marshmallow loving, and with both Telus' S6 and T-Mo's Note 5, the very latest version 6.0.1 is on the menu.

As ever, it may take a while for your device to receive the update. The wait could be anywhere from a few minutes to a few years days, though you can perhaps take some comfort in knowing that it's actually now on the home straight. If you'd like to be a tad more proactive, you could try to force the update by navigating your way through Settings --> About device --> Software update to see if the bundle is ready for you.
