Samsung began testing OneUI 5.1 on its Galaxy S22 series last month, and reports suggest that It has also begun testing the upgrade for its S20 range.
One UI 5.1 is being tested internally on the Galaxy S20, S20+, S20 5G, and S20+ 5G, along with the Galaxy S20 Ultra with firmware version G980FXXUFHWA1 (‘X” differs depending on the model).
I don’t have all the details about the One UI 5.1 update for the Galaxy S20 series yet. However, it will likely bring changes to the lock screen and other parts of the user interface to the 2020 Samsung flagship phones and other compatible devices.
Samsung might launch One UI 5.1 on February 1, when it’s scheduled to launch its Galaxy S23 series.
