Galaxy S9 and Galaxy S9+ owners could get the One UI 2.1 update in Korea later this week, according to one of Samsung's community moderators. Samsung had confirmed a few weeks back that it was targeting a June release for the Galaxy S9 and Note 9's One UI 2.1 update, and it seems the company will be sticking to schedule, at least for the Galaxy S9 and S9+.
Samsung has also seemingly confirmed that the One UI 2.1 update will bring the Pro video camera mode to Samsung's 2018 flagships. However, it remains to be seen if it will be the full-fledged version with support for adjusting shutter speed or a basic version that newer non-flagship phones have received with One UI 2.1. We really hope it's the former, as Pro mode video recording was available on the Galaxy S9 and Galaxy Note 9 before it was taken away with the Android Pie and One UI 1.0 update, a move that reeked of anti-consumer antics.
As is often the case, just because Samsung says an update will be released in a specified time frame doesn't mean it will actually happen. There could be a few delays along the way, and it could also take a few weeks for the update to arrive in markets outside South Korea. Whatever happens, we will keep you posted, so stay tuned.
Update: According to another Samsung community moderator, One UI 2.1 for the Galaxy S9 and Galaxy S9+ will be released next week instead of this one. The Galaxy Note 9 will also be receiving the update around the same time.
Thanks for the tip, Ming2 and Jeongchan!
