Samsung is pushing out a new software update for the Galaxy S9 and Galaxy S9+ in a handful of countries that brings the security patch version up to September 1. The update comes with firmware version G96xFXXSBETH2. You can download it over the air by opening the phone's Settings app, selecting Software update, and tapping Download and install. Alternatively, you can grab the latest firmware for your country from our archive and install it manually on your Galaxy S9 or S9+ using a Windows PC.
The latest Galaxy S9 update only has security fixes to offer. Those looking forward to One UI 2.5 will have to wait a little longer, and there's a good chance that the next Galaxy S9 update will have the updated version of Samsung's custom Android skin on-board. Samsung is already testing One UI 2.5 for the Galaxy S9, S9+, and Note 9 according to our sources, though it's unknown at this time how many of the new features will be made available to Samsung's 2018 flagships.
For those wondering, the Galaxy S9, Galaxy S9+, and Galaxy Note 9 are not eligible for Android 11 and One UI 3.0. All three phones will end their life on Android 10 and One UI 2.5, as Samsung's promise of three Android OS updates doesn't extend to any device released before the Galaxy S10, flagship or otherwise.
