Even though Android Pie has been around for months, Samsung devices are yet to get a taste of it. Earlier this month, Samsung unveiled their redesigned Android fork aka OneUI, which would be rolled out to eligible devices along with Android Pie. Recent updates to the Samsung Members app indicated that the beta program would begin on the 15th of November, followed by a confirmation from Samsung that the program would begin in the UK on the 20th. Today, South Korean variants of the Galaxy S9+ and galaxy S9+ have begun receiving the much-awaited OneUI-based Android Pie beta. Prolific leaker Ice Universe Tweeted a screenshot of what appears to be the Android Pie changelog in Korean.
