AT&T has started pushing out a new update to Samsung Galaxy Tab S 10.5 units on its network. Weighing in at 1,063MB, the update brings along Android version 6.0.1 as well as security patch for the month of September.
In addition, the update also includes the NumberSync feature that allows you to use your tablet to make and receive voice and video calls using your existing mobile number.
As is usually the case with OTA roll-outs, it may take some time for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your device's Settings menu.
