Now that the Android Pie rollout for the Samsung Galaxy S9++ and Note 9 is in full swing, it was only a matter of time before the beta program for Samsung’s 2018 flagships would begin. We saw some hints about the Galaxy Note 8 One UI beta program beginning soon via some early One UI builds which were spotted on Samsung’s servers. Today marks the official release of the OneUI-based Android Pie beta for the Samsung Galaxy Note 8

Registrations for the program are now open via the Samsung Members app. So far, the notice has been spotted only in India and Korea, but it is only a matter of time before it goes live in markets. Those who are interested can sign up by opening the Samsung Members (Samsung+ in the US) app and heading over to Notices. Over there, you’ll see one that says “OneUI Beta”. Tap it on it and sign up for the program. After some time, you’ll receive an update OTA with Android 9 firmware version N950FXXU5ZSA5 on your Galaxy Note 8.
