One UI 5.1.1 Expected Features
Seeing the company’s habit, we believe, the One UI 5.1.1 software may also focus on enhancing the usability of foldable phones and tablets. The vendor is also focussing on the premium tablet range as people continue to prefer Galaxy tablets in the Android segment.
With One UI 5.1.1, Samsung should further improve the interaction experience with Galaxy devices. It should bring new visual effects to offer an even more natural feel while switching across apps, using the multi-window, split screen, and one-handed mode.

Samsung One UI 6 concept displays gradient elements, interface rounding

Samsung is internally readying the One UI 6 software, which will bring the Android 14 to Galaxy devices. The Beta activity is about two months away, while concept creator SOUIC shared a handful of images displaying One UI 6 featuring aesthetic gradient elements, an elegant interface rounding, and beautiful blur.
The Quick Settings and Notification Panel got refreshed in the concept with beautiful blur, renovated brightness slider, and neat toggles. The notifications are now featuring padding from both sides to provide you with more convenient access across them.
Similar to Apple’s iOS, the expanded app settings panel is now presented with hard blurred background, which entirely makes the remaining home screen icons blurry. Thankfully, the expanded tools are now visible with an even clearer appearance with solid shape below.
Additional functional sections of the system Settings window are also aligned in the center with padding on both sides. The overall appearance got sticking, and it will be interesting to see if Samsung makes it happen int he official One UI 6 software.
