Every year, Samsung's new foldable smartphones debut with a new version of One UI. Next month, the company will debut two new foldable phones: Galaxy Z Flip 5 and Galaxy Z Fold 5. And with those new phones, Samsung could debut One UI 5.1.1 with some new features. However, it will be based on Android 13.
Samsung mentions One UI 5.1.1 in the changelog for the newest version of Nice Catch
Samsung has released a new version (5.0.01.02) of the Nice Catch app (via Daniel Scuteri) for Galaxy phones compatible with Good Lock. The official changelog of the newly updated app mentions support for One UI 5.1.1, along with some minor improvements and bug fixes. It probably means that One UI 5.1.1 will be released soon, and the Galaxy Z Flip 5 and the Galaxy Z Fold 5 could be the first phones released with it.
The South Korean firm could then release the One UI 5.1.1 update to older phones, similar to how it released One UI 4.1.1 to older Galaxy phones after the launch of the Galaxy Z Flip 4 and the Galaxy Z Fold 4. We still don't know which features will debut with the One UI 5.1.1 update, but it could bring some optimizations for foldable phones, including new widgets and apps for the Galaxy Z Flip 5 and its bigger cover display.
Samsung is also expected to release the One UI 6.0 Beta update sometime next month, starting with the Galaxy S23 series. Google released Android 14 Beta 3 last night, and it has attained platform stability for the newest version of Android. It brings improved privacy and security, intuitive navigation gestures, more optimizations for foldable phones and tablets, and more customization features.
