As you know, Samsung releases different variants of the same device based on network configuration and localizations. The timing of OS updates released by the manufacturer also differs. Just yesterday, we published a guide about manually updating the Galaxy Tab A 8.0 SM-T355 to Android Marshmallow. It’s true that the OTA has been rolling out for the tab for weeks now, but today we’ll see how we can install Android 6.0.1 Marshmallow on Samsung Galaxy Tab A SM-T355Y.

The Android 6.0.1 Marshmallow update for the Samsung Galaxy Tab A bring a host of new improvements, bug fixes, and exciting features. The new update improves performance and stability. The new App Standby and Doze features improve the performance of the battery life so that you can use your tablet for longer.

Besides, the Marshmallow update will also add quick scroll and app search feature in the app drawer so that you can access apps quicker. Also, you can activate Google Now on Tap simply by holding the Home button to get contextual information just when you want.

The Android 6.0.1 Marshmallow OTA update is being pushed in countries like Australia, New Zealand, India, Sri Lanka, Vietnam, etc. for a while now. However, if you own Samsung Galaxy Tab A SM-T355Y and do not belong any of the countries listed above, you can install the Marshmallow firmware using Odin and start enjoying the latest update right away. Those who have rooted and installed a custom recovery on their Tab A will not get the OTA from Samsung but they can get Marshmallow by installing it manually.
