Everything about One UI 5.1.1


Last updated: August 14th, 2023 at 12:18 UTC+02:00


In addition to a major One UI version bump that accompanies every year's new Android OS update, Samsung releases two minor One UI updates in the first and second half each year, and for 2023, those are One UI 5.1 and One UI 5.1.1.

The latter firmware debuted on Samsung's 2023 foldable devices (Galaxy Z Fold 5 and Galaxy Z Flip 5) and flagship tablet (Galaxy Tab S9) on July 26. Like the previous x.1.1 One UI updates, version 5.1.1 is designed specifically for the foldable and tablet form factors.

Even if One UI 5.1.1 will be relatively short-lived and quickly replaced by One UI 6.0, most of version 5.1.1's features and improvements have elevated the user experience, particularly for Galaxy tablets and foldable phones, which makes it a worthwhile release in its own rights. Here's everything One UI 5.1.1 brings to the table.

One UI 5.1.1 release

Even though One UI 5.1.1 debuted with the Galaxy Z Fold 5, Z Flip 5, and Galaxy Tab S9 series, Samsung also released a beta version of One UI 5.1.1 for Galaxy Z Fold 4 and Galaxy Tab S8 owners in Korea on July 3rd, 2023.

Samsung also rolled out the first One UI 6.0 beta for the Galaxy S23 series on August 11, so there's a high probability that not many devices will get One UI 5.1.1 before One UI 6.0 goes live.
