The Samsung Galaxy S8 series and Note 8 have started receiving Android 9.0 Pie in the US
It may be a month later than planned, but the Samsung Galaxy S8, S8+ and Note 8 have started to receive One UI on some US carriers, according to multiple users on Reddit. The Android 9.0 Pie-based OS update has also been rolled out with the March 2019 security patch and comes via an over the air (OTA) update.
AT&T and Sprint have released the update to all three devices, while T-Mobile has only updated the Galaxy S8 and S8+ at the time of writing. We suspect that the Note 8 will not be far behind though as it is listed as being under "certification process testing" on the T-Mobile website.
Moreover, if you are unfamiliar with One UI, it succeeds Samsung Experience, which replaced TouchWiz in 2016. The redesign integrates a Night Mode for the first time and introduces Bixby Routines, which we have covered in our recent Galaxy S10 and Galaxy S10+ reviews. Samsung promises that One UI has less bloatware than previous versions of Android and that it will be easier to use with one-hand than Samsung Experience.
If you have not been prompted to download One UI already, you can check whether the update is available for your device by heading to Settings, Software update and pressing Download updates instead. Unfortunately, the Galaxy S7 has not received the update to One UI, as per Samsung's Android Pie update roadmap.
