TL;DR
- One UI 9 restores a built-in option to hide the taskbar on Samsung tablets that disappeared with One UI 8.
- In standalone DeX, the setting can hide both the taskbar and status bar, while external-display DeX can hide the taskbar.
- Samsung is also adding more freedom to position the regular tablet taskbar on the left, center, or right.
Samsung’s switch to the new desktop mode in Android 16 came with a frustrating side effect: several familiar DeX controls disappeared in One UI 8. Samsung has gradually been putting some of those pieces back, including an auto-hide taskbar option that returned on phones with One UI 8.5. But tablets were conspicuously left out, and now One UI 9 appears to finally close that gap while adding another useful taskbar trick.
A Reddit user testing a Samsung Galaxy Tab S12 Ultra has found that One UI 9 restores the option to automatically hide the taskbar on tablets. Better still, the setting works directly on the tablet rather than being limited to an external monitor.
