It's Marshmallow week for those using Samsung devices on Verizon's network. The carrier upgraded the Galaxy S5 to Android 6.0 just yesterday, and it is now pushing out the update to the Galaxy Tab S2. The Galaxy Tab S2 is the first Samsung tablet to be getting Marshmallow on Verizon, although it might also be the last as there is no guarantee that older Galaxy tablets will ever get the newest iteration of Android.
The update brings all the major Marshmallow features, including Google Now on Tap, Doze, and advanced app permissions. Also onboard are new functions in the email and gallery apps, and the option to add images in the Memo app. The firmware version is T817VVRU2BPE1, and the update is available over the air both through Wi-Fi and cellular connections. Of course, given the size of these updates, using a Wi-Fi network would be the best thing to do.
Grab the update from the Settings » About device » Software update menu, but keep in mind that not everyone will get it right away and there could be a wait of a couple of days involved before your Galaxy Tab S2 makes the jump to Android 6.0.
