Despite the fact that the original Samsung Galaxy Tab S has already celebrated its second birthday earlier this year, Verizon decided Samsung's 10.5-inch tablet is still worth supporting as the US carrier just started rolling out Android 6.0 Marshmallow to the device. More specifically, software version MMB29M.T807VVRU1CPG6 should now be available to most Galaxy Tab S owners in the US using Verizon's network. If you prefer to update your device over the air, make sure its battery is fully charged and that the tablet is connected to a Wi-Fi network. After that's done and you still don't see a notification about a new software version being available, you can check for the update manually by opening the Galaxy Tab S Settings app, then navigating to "About Device" and "Software Updates". On the next menu, just tap the "Check for updates" option and wait. Naturally, if you have any issues or simply prefer to perform updates via a PC connection, you can upgrade your device by downloading Verizon's Software Upgrade Assistant to your computer, installing it, connecting the tablet, and letting the program do its magic automatically.
Verizon stated that this software upgrade has been specifically tested and optimized for the original Galaxy Tab S and that it also comes packed with the latest security patches in addition to updating the device with a new Android version. In other words, owners of Samsung's 2014 tablet can now enjoy all of the great Marshmallow features such as the new app permissions page, Google Now on Tap, and Doze. In addition to that, the update also introduces new tools and pen settings which you can access from the Gallery app. For better or worse, some apps will be removed in the process of updating your device. According to a change log published by Verizon, this update removes Amazon Music, Amazon Appstore, VZ Navigator, WebEx, and e-Meeting.
There is almost no doubt that the Marshmallow update is the last major Android upgrade the original Samsung Galaxy Tab S will receive. If you're still unable to download and install it, note that the roll-out has just started so it may take a few days before everyone is able to download and install the update.
