T-Mobile is finally going to release the Android 6.0.1 Marshmallow update to two very popular phones, the Samsung Galaxy S6 Edge Plus and Galaxy Note 5 over the air (OTA). Sometime before May 20, all T-Mobile Samsung Galaxy S6 Edge Plus and Galaxy Note 5 devices should finally have their Marshmallow.

Android 6.0 Marshmallow, also known as Android M, has certainly taken its time making its way to major OEM manufacturers' devices. According to the last update by Google in early April, still only 4.6 percent of all devices that actively run the Google Play Store have been updated to some form of Android Marshmallow. 

Still, that number has doubled since February of this year.

But as Android M updates have been released for most newer Android phones by Motorola, HTC, Samsung, and others, the unfortunate souls who bought a T-Mobile brand Samsung Galaxy Note 5 or Samsung Galaxy S6 Edge+ have had to patiently wait to hear any news about their update. Meanwhile the same devices on many other carriers, and outside of the U.S., have been up to date for months.

No longer, according to CNET, which reported that T-Mobile subscribers with those two popular Samsung phablets should start receiving OTA update notifications beginning this week.

If you haven't been pinged by T-Mobile for your upgrade yet, not to worry: The rollout will take place in stages over the next month, and everyone on the carrier should be able to update to Marshmallow sometime before May 20.

When you do get an update notification, be sure to have the device close to fully charged, and especially because this particular upgrade is 1.34 gigabytes, make sure you are on a healthy WiFi connection before downloading.

Android Marshmallow brings several under-the-hood improvements and bug fixes, along with some new user features like Google Now on Tap, Doze mode for better battery life, and granular control over individual permissions for apps.
