Samsung to deliver One UI 3.1.1 features to the Galaxy S20, Galaxy S21 and Galaxy Note 20 series as another One UI 3.1 update

Typically, Samsung brings interim versions of One UI to current and recent flagships, as was the case with One UI 2.5. However, One UI has only jumped to version 3.1.1 for the Galaxy Z Fold 3 and Galaxy Z Flip 3, rather than the expected One UI 3.5. As its name suggests, One UI 3.1.1 is a marginal bump on One UI 3.1, itself a slight revision of One UI 3.

In a community post, Samsung confirmed that it will release One UI 3.1.1 to other flagships in all but name. Unfortunately, many outlets ran with headlines centring on the idea that past and current devices will not receive One UI 3.1.1. In truth, Samsung has promised to deliver the benefits of One UI 3.1.1 to devices already on One UI 3.1. These will arrive in a software update, although not one tied to the removal of advertisements.

Apparently, the Galaxy S20 series will receive the update starting this week, with the Galaxy S21 series following from August 25. Samsung will then update other flagship series, such as the Galaxy Note 20, after that - probably sometime in September.

Please note that these update schedules only apply in South Korea. We imagine that Samsung may take a few more weeks to bring One UI 3.1.1 features to One UI 3.1 devices globally, albeit likely in the same rollout order. In short, One UI 3.1.1 is arriving on older and current devices, but with no revision change.
