Samsung began the process of testing OneUI 5.1 to its Galaxy S22 series last month, and reports suggest that Samsung has begun test-running the upgrade for its S20 range as well.
One UI 5.1 is being tested internally on Galaxy S20, Galaxy S20+, Samsung Galaxy S20 5G, Galaxy S20+ 5G along with the the Galaxy S20 Ultra with firmware version G980FXXUFHWA1 (‘X” differs based on which model).
We don’t yet have the complete changes for One UI 5.1 for the Galaxy S20 series yet, however, it’s likely to bring the lock screen as well as other UI adjustments to the 2020 Samsung flagships as well as other phones that are eligible.
Samsung might launch One UI 5.1 on February 1, at which time it’s scheduled to launch its Galaxy S23 series.
