With the Samsung Galaxy S6 Android 6.0.1 Marshmallow release pushing ahead, we want to take a look at the most important things to know right now about the Android 6.0.1 Marshmallow release for the Galaxy S6 and Galaxy S6 Edge.
For weeks we've seen Samsung Galaxy S6 Android Marshmallow details tease owners of the regular variant, the Galaxy S6 Edge, and the Galaxy S6 Edge Plus. Until recently, those details didn't include an actual roll out.
Samsung has finally rolled out the red carpet for the Galaxy S6's Marshmallow update and it appears that the update is starting to roll out, in limited fashion, to Galaxy S6 and Galaxy S6 Edge models. It's even rolling out in the United States.
The Android 6.0.1 Marshmallow update takes the Galaxy S6 and Galaxy S6 Edge from Android 5.1.1 Lollipop to Google's most up-to-date OS.
With a Samsung Galaxy S6 Marshmallow release now underway, we want to take a look at the most important things Galaxy S6, Galaxy S6 Edge and Galaxy S6 Edge Plus owners need to know about the release, Android 6.0.1, and more.
We'll continue to update this with new information as we get it. Samsung's Android roll outs are slow and the Galaxy S6 Android Marshmallow release will almost certainly take several months to hit every single device.
Samsung Galaxy S6 Marshmallow Release Date

Other Release Details
Now that Samsung's confirmed plans to release the Galaxy S6 Android 6.0.1 update in Korea and Europe, we are starting to see some other dominoes start to fall.
AT&T will reportedly start rolling out its Galaxy S6 Android 6.0.1 update on March 14th. This hasn't been confirmed.
Canadian carrier Telus has confirmed a trio of dates for its Samsung Galaxy S6 Marshmallow release. Up first is the Galaxy S6 Edge Plus update. It's expected to arrive on April 7th after several days.
After that, it's the Galaxy S6 Edge and Galaxy S6 Marshmallow updates. Both are expected to land on April 14th.
It's important to note that these dates are "approximate and subject to change" so there's a chance we could see further delays.
Canadian carrier Bell has also confirmed plans to roll out a Galaxy S6 Marshmallow update in March. It hasn't outlined a specific date yet but Canadian carriers typically roll their Android updates out around the same time as one another.
Elsewhere in North America, T-Mobile USA is planning Android Marshmallow updates for the Galaxy S6, Galaxy S6 Edge and the Galaxy S6 Edge+.
The carrier confirmed these updates several weeks ago and two of them, Galaxy S6 and Galaxy S6 Edge, have finally moved past the "Manufacturer Development" stage. They're now in for testing at T-Mobile, a sign that their release is close.
As for the Galaxy S6 Edge Plus update, it's still lagging behind in "Manufacturer Development" mode. It's not clear when it will move. 
A report from last year suggests that all five major U.S. carriers (AT&T, Verizon, T-Mobile, Sprint, U.S. Cellular) will be pushing Android Marshmallow out to the Galaxy S6 and Galaxy S6 Edge. Not that this comes as a surprise. The Galaxy S6 is less than a year old.
With Verizon pushing out the Verizon Galaxy Note 5 Marshmallow update, it should only be a matter of time before its Galaxy S6 model, and the others beyond Sprint's, gets a taste of Android 6.0.1.
Galaxy S6 Marshmallow Update: What's New
Thanks to the Galaxy S6 Marshmallow beta, Samsung's announcements, and the company's very own Galaxy S6 and Galaxy S6 Edge Marshmallow consumers guide, we know what to expect from the updates in Korea, Poland and around the world.
The Galaxy S6 Android Marshmallow updates will deliver a number of new features, enhancements and fixes to the two flagship smartphones including changes to the look of app icons and a UI that prominently features the color white.
Samsung's updates come with Google Now on Tap which allows you to quickly bring up information on whatever you're looking at simply by holding down the home button. They also feature better control over app permissions, improved fingerprint support, and the battery saving feature Doze.

The company's also outlined changes to Samsung Internet 4.0 and Cross App boost functionality.
Samsung's new browser comes with improved security and functionality including a new Secret Mode that's very similar to Chrome's Incognito mode in that it doesn't store "browsing history, cookies, passwords, auto-fill data or anything else."
The Samsung Galaxy S6 Marshmallow update's new Internet 4.0 app also brings browsing support for Samsung's Gear VR.

In addition, the Cross App boost functionality "allows users to operate certain apps from within other apps."

Android 6.0.1
Samsung isn't rolling out the old Android 6.0 update. It's rolling out the newest version dubbed Android 6.0.1 Marshmallow.
Android 6.0.1 is a whole lot different than the Android 6.0 update and there are some notable changes Galaxy S6 and Galaxy S6 Edge users will want to be aware of as the roll out grows in size.
Samsung's Android 6.0.1 update for the Galaxy S6 and Galaxy S6 Edge should bring the following along with it:
Additional quick settings toggles for Private Mode in the status bar. New emoji characters (Android 6.0.1 brought more than 200 to Nexus users). Improved visibility of notification panel icons. When a fingerprint isn't recognized, you will only get vibration feedback. A new 'Install overnight' option that will let you install an update at night between the hours of 2 to 5 AM. Changes to the Galaxy S6 Edge panel. The changes to the Galaxy S6 Edge panel can be seen in the video above and on Samsung's website. The company outlines the biggest changes coming to the Edge models with Android 6.0.1 Marshmallow
For more on Android 6.0.1, take a look at our walkthrough. It will take you step-by-step through the differences between Android 6.0 and Android 6.0.1.

It's important to note that not every Galaxy S6 Marshmallow update will be created equal. Carriers typically put their own spin on these updates and we expect to see mostly minor but maybe some big differences between the updates in the United States and around the world.
Most carriers are mum about their plans for Marshmallow so we'll just have to wait and see what those are.
Marshmallow Problems
Google's Android 6.0.1 update (and Android 6.0 update for that matter) has been problematic for Nexus smartphone and tablet users. We expect some of the same problems to plague Samsung's Galaxy S6 and Galaxy S6 Edge Marshmallow upgrades.
Samsung put these updates through a public beta process. And while the beta process likely caught some of the more glaring problems, there's no way it caught them all.
Problems always slip through the cracks and Galaxy S6 and Galaxy S6 Edge owners will want to prepare for Android 6.0.1 issues.

We've been taking a close look at Android 6.0.1 problems in the weeks since the updates release. We encourage you to get familiar with the most common problems (battery life, etc) and get a feel for some potential fixes for those issues.
We'll keep you posted about Galaxy-specific Android 6.0.1 problems once the roll out picks up the pace in Korea, Europe and the United States.
