Samsung has started rolling out the Marshmallow update to the Galaxy Tab S, bringing the uncertainty to an end. Specifically, the update - which weighs in at over 800MB - is hitting 10.5-inch LTE models (SM-T805) in Germany. As is usually the case with OTA roll-outs, it may take sometime for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for it by heading to your device's Settings menu. We expect the update to soon start hitting other variants of the tablet as well. Via
