One-Handed Mode Toggle auf Samsung
Samsung phones with large displays are hard to operate with one hand, especially while walking or holding something in the other hand. One-handed mode belongs to Samsung's accessibility features and creates a smaller, movable version of the screen that fits within thumb range.
The feature does not change the actual screen resolution. It only scales the visible interface down and lets you dock it to the left or right, so notifications, apps, and system menus stay reachable without changing your grip.
Where to find it
Open Settings ➔ Advanced features ➔ One-handed mode and switch the toggle on. You can also enable a gesture, such as swiping diagonally from a bottom corner, to trigger the shrink effect from any screen.
Once active, drag the small arrow on the edge of the scaled window to move it left or right. Pinch the corner handle to resize the window if the default size still feels too large.
Turn the feature off from the same menu if the reduced view makes text and icons too cramped, or if you mainly use the phone with a case or stand that already gives you a comfortable grip. One-handed mode works independently from Split screen or gesture navigation and can be combined with either.
