Samsung's One UI 2.1 is currently only available on four phones, but that number will expand.
An official Samsung community moderator in Korea has said that One UI 2.1 will be released for the Galaxy Note 10 and Note 9 models as well as the Galaxy S10 and S9 phones (via SamMobile). One UI 2.1 is currently only available on the Galaxy S20, S20+, S20 Ultra, and Galaxy Z Flip.
There's no word yet on when the One UI 2.1 update will be brought to these former Samsung flagships, but we might see it hit the Galaxy Note 10 and S10 phones first since they're newer, followed by releases for the Note 9 and S9 series.
One UI 2.1 isn't a huge update, and some of its features that are hardware specific won't be brought to older phones. For example, the update includes the ability to activate 120Hz screen refresh rate, but these older Galaxy phones don't have the hardware for that feature.
What we could see brought to the Galaxy Note 10 and Note 9 as well as the Galaxy S10 and S9 include additional Screen Zoom settings, letting you make the items on your display smaller or larger. Another feature that could be brought to older phones is Quick Share, which is Samsung's AirDrop-style feature for quickly sharing files between devices.
While One UI 2.1 may not sound like the most exciting update around, we're still glad to get word that Samsung is planning to bring its newest One UI update to former flagship models.
