Samsung Galaxy Tab S3 update: April security patch arrives as build T820XXU1AQD6

Update [April 21,2017]: Samsung is starting to push out the April security patch to the Galaxy Tab S3. The update, which comes in as version T820XXU1AQD6, also includes various bug fixes and under-the-hood performance improvements. Before downloading the update, ensure that your device has at least 50% charge and download over WiFi to save on data charges.


Samsung launched its first Nougat powered device Galaxy Tab S3 in Barcelona last month during the Mobile World Congress event. Even as it prepares to release this latest Tab in other countries, it seems the OEM wants to make sure all the bugs on board the Tab S3 are fixed. To this end, the first firmware update for the Tab has been released. Notably, the firmware available is for the LTE model of the Tab S3, not the WiFi model.

The firmware update installs the March security patch on Galaxy Tab S3 and is being rolled out as build number T825JXU1AQC4. Apart from the security patch update, regular bug fixes have made their way into this firmware. It also comes with stability improvements.

The new firmware build comes as an OTA update. And as is the case with such updates, it is being released gradually in stages, therefore, it could take a few days for all of the Tab S3 units to receive the new software. Now not everybody has the patience to wait. If you are one of them and are the proud owner of a Galaxy Tab S3, you might like to know how to check for the new firmware update. In that case, simple head to Settings > About device > Software updates.

Samsung Galaxy Tab S3 should soon make its way across several new markets viz China, Taiwan, Hong Kong in the east and US, Germany and Canada in the west. In fact, it is already up for pre-order in Germany and Canada while the China, Taiwan and Hong Kong models of the Tab have cleared FCC certification.
