Owners of the international version of Samsung's Galaxy Note 4 can now upgrade to the latest version of Google's mobile OS, Android 6.0.1 Marshmallow.

The international Galaxy Note 4, model N910C, is the Exynos-powered version of Samsung's phablet of 2014. The Snapdragon variant, popular in North America, is just starting to receive the update to Marshmallow, as well.

Sprint, for example, recently released the Android 6.0.1 updates to its subscribers' Galaxy Note 4 and Note 5, along with the Galaxy S5 and S5 Sport. As to when other U.S. carriers such as AT&T, T-Mobile and Verizon will follow suit still hangs in the air.

Nonetheless, Samsung unleashing Marshmallow on its past flagship phablet should be good news for other owners whose devices are locked onto other carriers. It may not be too long from now until every variant of the Note 4 gets all the latest features Google has packed into Android 6.0.1.

Note that Samsung's latest update release is not just for Android 6.0, but also for Android 6.0.1, which is the newest Marshmallow build so far. The size of the update is about 1.3 GB. That's reportedly smaller than a previous build for the Note 4 on another network.

Seeing as to how the Galaxy Note 4 is nearly a couple of years old, the device itself can start to feel a little old and laggy especially near the two-year mark of its product life cycle. The upgrade to Marshmallow, however, should give Note 4 owners a fresh experience with a brand-new operating system.

For example, Marshmallow should help to increase the Note 4's battery life with Doze, which basically idles all the apps running in the background if they're not actively in use. Also, Google Now On Tap and advanced app permissions in Marshmallow will give Note 4 owners greater control of their device and more speedy access to relevant information on their screens.

As it is the newest build of Android, Google has also thrown in some extra 200 new emojis along with the latest Android security patches for the month of April.

It's not just Google throwing in some goodies, however. Samsung has also refreshed TouchWiz in this update. One of the new features in TouchWiz, for example, is the Note 5's memo feature, which lets users write on the screen when the screen is off. That's now also being ported over to the Note 4 as well.
