Samsung’s latest Android 6.0 Marshmallow upgrade for the Galaxy S6 and Galaxy S6 edge is now rolling out globally, just two weeks after making its debut in South Korea. The release brings big improvements to TouchWiz and new features.

Marshmallow is by far the biggest upgrade the Galaxy S6 and S6 edge have received since they launched just under a year ago. User have had to wait a long time for it (it first arrived on Nexus devices last October), but it’s here now.

Samsung has baked lots of TouchWiz improvements into this upgrade, alongside Marshmallow features like Google Now on Tap, Doze, and the new app permissions system. S6 edge users also get enhanced edge capabilities, with more pages and greater customization.

It will take several weeks for this upgrade to reach all Galaxy S6 and S6 edge owners, so don’t worry if you don’t see it today. Those with unlocked devices can expect to get it first, followed by those with locked handsets following carrier approval.

“Samsung will make separate announcements on details of OS updates schedule for each market according to market situation and carriers’ requirements,” the company says. It has also promised Marshmallow upgrades for other smartphones “soon.”
