From today, T-Mobile US customers using a Samsung Galaxy Tab S are set to start to receive an over the air software update on their device will will bump the version up to Android 5.0 Lollipop. The news was first broken this morning but at the time, T-Mobile's software updates progress page was still showing the new version of Android as still being tested by the carrier. However, T-Mobile have subsequently updated their website and it's now showing the update to 5.0 Lollipop as being live. If you use the T-Mobile US network and have a Tab S, your device may already be showing the software update but if not, you can manually check from the Settings application.
However, you might want to think twice before trying to download the software update over your LTE connection as it weighs in at a hefty 1.1 GB. The update also requires 3 GB of free memory on your Tab S before you start to download the update. As with all Samsung software updates, your device will also need plenty of battery too. It's good practice to put the tablet on the charger before running the update. After running the update - which will take some time - your Tab S device will have around 1 GB less free space as the Android 5.0.2 Lollipop and the Samsung TouchWiz update requires considerably more space on the device. And finally, after running the update you will likely need to visit the Google Play Store in order to check for application updates, as many applications will have a newer version optimized for Android Lollipop.
Once customers are over the logistics of running the update, Android 5.0.2 Lollipop on the Samsung Galaxy Tab S brings about it a number of improvements. The operating system is more responsive than the previous Android 4.4 KitKat version as Google have improved the application run time. There are new notification controls and theoretically enhanced battery life thanks to a new network scheduler, which allows cooperative applications to schedule when they will require network access and thus reduces the amount of times the device is woken up for an application or service synchronization event.
