If you have a Galaxy S8, prepare yourself for a significant software update. Samsung finished its testing of Android 8.0 Oreo on last year’s flagship and is starting to roll it out in several markets around the world. While the software update hasn’t arrived in the United States just yet, it could be close as the company just posted update notes highlighting what’s new.

The latest version of Android comes with Samsung Experience 9.0, the company’s software overlay. So the software update is both an improvement for Android as well as Samsung’s in-house features.

Samsung’s own improvements are largely for its keyboard, Edge screen, always-on display, Samsung Cloud, and DeX. Oreo, meanwhile, focuses a lot on stuff you don’t see. In that sense, Oreo for the Galaxy S8 isn’t this major upgrade that’ll change the user interface dramatically. The heavy work was done behind the scenes.

Make sure you have individual Samsung apps updated first, though. The company recommends apps like Samsung Pay, Samsung Internet, Samsung Notes, and Email be updated individually before grabbing Oreo.

Here’s the full changelog:

Biometrics To improve your security, features that use biometrics (face, fingerprints, and irises) are only available when you use a secure screen lock type (pattern, PIN, or password). When you switch to a non-secure screen lock type (Swipe or None), biometric authentication is suspended for unlocking and for verification in apps like Samsung Pay and Samsung Pass. If you’re using biometrics now without a secure screen lock type, you’ll be able to continue after the upgrade, but changing to a secure screen lock type is recommended.
