You can make a Galaxy phone easier to use one-handed while keeping the full display visible. Start with One Hand Operation+ for customizable edge gestures, or switch Samsung Keyboard to a one-sided layout if typing is the main challenge. Samsung’s separate One-handed mode is another option, but it temporarily shrinks the displayed area.
Choose an option that keeps the full display visible
“Without changing the screen size” can mean either leaving the phone’s physical display unchanged or keeping all on-screen content visible at its normal size. The options below preserve the full visible display; One-handed mode, covered separately, does not.

| Option | What it helps with | Shrinks displayed content? | How you use it |
|---|---|---|---|
| One Hand Operation+ | Opening apps and reaching common actions | No | Swipe from a configured edge handle |
| Samsung Keyboard one-handed layout | Typing | No; only the keyboard layout changes | Move the keyboard to the left or right |
| Assistant menu | Accessing common controls and gestures | No | Tap its floating on-screen shortcut |
| Voice Access | Hands-free interaction | No | Use voice to control supported actions |
Set up One Hand Operation+ for easier navigation
Samsung describes One Hand Operation+ as an app that assigns actions to short swipes from customizable screen-edge handles. This lets you trigger selected actions without reaching across the display. Samsung’s examples include launching apps and actions such as taking a screenshot or turning on the flashlight. Samsung’s One Hand Operation+ guide describes the feature and its customization options.
Recommended Free Tools
Configure the handles and actions to suit the way you hold the phone. Start with a small set of gestures you can remember; adding many gestures can make it harder to recall which swipe does what. The available actions and exact setup screens can vary by device and software, so search Settings or the app for “One Hand Operation+” if the labels differ.

Move Samsung Keyboard to one side for typing
If reaching keys is the problem, change the keyboard layout rather than the whole screen. Samsung’s US support instructions give this path: Settings > General management > Samsung Keyboard settings > Mode. Choose One-handed keyboard. The keyboard shifts to one side, and its arrow control lets you switch sides. Samsung also documents keyboard size and transparency adjustments. See Samsung’s keyboard settings guide for its instructions.
This changes the keyboard’s position and footprint, not the size of the rest of the display. The exact mode names and options may differ with the device, software version, or keyboard configuration.

Use an on-screen menu or voice for other controls
Assistant menu
Assistant menu places a floating shortcut on the screen that opens a menu of common controls and gestures. It can help when reaching buttons or performing gestures is difficult. Samsung’s Galaxy S23 manual says the floating icon can open menus across panels and show contextual menus in selected apps; behavior may differ on other models. Samsung’s interaction and dexterity guide covers Assistant menu and related features, while the Galaxy S23 series manual describes its floating shortcut.
Voice Access
Voice Access can launch apps, select buttons, swipe, and type by voice, reducing the need to reach across the display. Samsung’s US support page lists English, French, Italian, German, and Spanish as currently available languages. Check your device and region for availability before relying on it. Samsung’s guide to interaction and dexterity features provides more information.

Know what Samsung One-handed mode changes
One-handed mode is built into Galaxy phones, but it temporarily reduces the displayed screen area. It can bring controls closer to your hand, though content appears in a smaller, repositionable window rather than across the full display. Samsung warns that some features may not be available while the mode is active.
- Open Settings > Advanced features > One-handed mode.
- Enable the feature and choose Gesture or Button, if those choices appear.
- Use the selected activation method to reduce the display area. Move the window with the arrow or gray bar when available.
Samsung US says the reduced view returns to normal after the screen turns off or the phone is locked. Samsung Australia describes activation by swiping down at the centre of the bottom edge or double-tapping the Home button, depending on the selected action, and describes moving or resizing the minimized window. Those details come from its guide for Australian-variant devices, not a universal instruction for every Galaxy. Samsung US One-handed mode instructions and Samsung Australia’s guide, updated August 10, 2026 explain their respective steps.

If a setting or gesture is missing
Galaxy menus and feature availability vary by model, region, Android or One UI version, and keyboard configuration. Samsung’s Australian guide explicitly applies to Australian-variant devices, and Samsung’s US guidance cautions that not every feature works in One-handed mode. If a path does not match your phone, search Settings for the feature name, such as “One-handed mode,” “Assistant menu,” or “Samsung Keyboard.” Samsung’s One UI design guidelines also discuss accessibility considerations such as screen reach and complex gestures.
