Just in time for the holidays, Samsung has begun releasing its Android Pie update for the Galaxy S9. SamMobile was first to notice the German release, while other users on Twitter and Reddit have seen the update become available in the Netherlands and Slovakia as well. Along with the upgrades made by Google, Android Pie on the S9 also brings Samsung’s One UI, a new user experience which is intended to make apps easier to use on larger phones, amongst other improvements.

Although this latest update has come to Samsung’s devices a lot more quickly than previous versions of Android did, the South Korean firm is still lagging behind the likes of Nokia, OnePlus, and even HTC with its update schedule. Google has previously attempted to speed up the adoption of new Android versions with Project Treble, but despite the program’s introduction in early 2017 only 21.5 percent of Android devices were running Android Oreo or later as of late October this year.
