Following in the footsteps of AT&T, US Cellular is now rolling out the Android 6.0.1 update for the first-generation Galaxy Tab S 10.5. In addition to transporing all of the features bundled into the latest build of Marshmallow, the upgrade also packs the bug fixes included in October's Security Maintenance Release (SMR).
If you own a US Cellular-branded Galaxy Tab S 10.5 and would like to see if it’s ready for your unit, open up Settings, followed by About Device, select Software Update, then hit the Update Now button. Alternatively, you could always wait until you receive a push notification on the device prompting you to download and install the upgrade.
Thanks, Jonas!
