And now it's time for its smaller sibling to be on the receiving end of the same new software release. Once again in Germany, the LTE-enabled Galaxy Tab S 8.4 is now getting the Android Marshmallow update too.

Samsung emphasizes a few things in its changelog, such as the fact that you can "exercise greater control over app permissions", see a redesigned app drawer, and take advantage of better battery life through Doze. Additionally, you should expect some unnamed bug fixes and stability improvements to be packed inside the update.
If you own a Galaxy Tab S 8.4 LTE purchased from Germany and haven't yet seen the update notification, you can manually check for the new software by going to Settings > About device > Software update. Hopefully Samsung will release the new OS version for these tablets in many more regions soon.
