About few weeks ago, there were sources suggesting Samsung will be releasing One UI 2.1 update for Galaxy S10 and Note 10 series. And now, there are more devices which are supported and will be receiving the new One UI 2.1 update!
On February, both the Galaxy S20 series and Galaxy Flip is powered by Android 10 and running on One UI 2.1. These were the exclusive One UI 2.1 back then.
Nonetheless it is surprising that the One UI 2.1 was released onto the older generation S9 and Note 9 series. However, S10 and Note 10 series will receive the update first.
