A week after it started making the rounds for the Wi-Fi model in the US, T-Mobile has started rolling out the much-anticipated Android 9.0 Pie update for its LTE variant of the Galaxy Tab S4 — bundling all of the new features baked into Pie, as well as Samsung's revamped One UI user interface.
As for what's built into Pie for the Galaxy Tab S4, we're looking at a Night mode, which makes the interface easier on your eyes in the evening and extends battery life when you're running low on juice, especially when coupled with the new Adaptive Battery optimization tool that's enabled out of the box; improved notification management, and more.
Elsewhere, the LTE model of the Galaxy Tab S4 was treated to a similar update at the beginning of April in France. That same release started cropping up in Brazil, Chile, India, Malaysia, Peru, Taiwan, and the United Arab Emirates and the United Kingdom soon thereafter — and now it's in the US.
T-Mobile is pushing out the update, which also bundles improvements for Samsung's Bixby assistant and well as support for HEIF images, in stages. To check to see if it’s available for your Galaxy Tab S4, head into Settings, navigate to Software update, then hit Download updates manually.
