Each passing day brings us closer to the Android 10 and One UI 2.0 beta program for the Galaxy S10 lineup, and as you would expect, Samsung will be testing the next version of Android for other devices as well. After the Galaxy S10, Galaxy Note 10, and Galaxy S9, the Korean giant has started testing Android 10 on the Galaxy Note 9.The latest test firmware for the Galaxy Note 9 has build number N960FXXU3DSJ3, as discovered by the folks over at GalaxyClub. The letter ‘D’ in the build number confirms that this isn’t firmware based on Android Pie – those have the letter ‘C’ instead. While the presence of test Android 10 firmware doesn’t mean there will be a beta program for Galaxy Note 9 owners, we can assume that there will be one based on how Samsung included the Galaxy Note 8 for the Android Pie beta.The Galaxy S10 beta program will launch first, as revealed by Samsung, and we can expect the Galaxy Note 9 (and Galaxy S9) beta a month or so after that. As far as the stable worldwide release of Android 10 is concerned, you can expect a similar time difference between the releases for Samsung’s 2019 flagships and the ones from last year. Do keep in mind that it’s all speculation at this point, and nothing is official until Samsung says it is.
