For quick one-handed tasks, keep the Galaxy Z Fold8 closed and use its Flex Window. When you need to reach controls inside an open app, try Samsung’s One-handed mode to shrink the active display area. Samsung’s instructions for that setting are general Galaxy-phone guidance, not Fold8-specific, so check whether it appears on your phone.
Choose the right one-handed approach
| Approach | Best for | How it helps |
|---|---|---|
| Closed Flex Window | Notifications, quick settings, and supported apps such as messaging or music | Lets you handle quick tasks without opening the phone. |
| One-handed mode | Reaching controls while using an app on the open display | Shrinks the active display area so more of it is within thumb reach. |
| One Hand Operation+ | Launching chosen actions or apps with a thumb swipe | Adds customizable gestures at the left or right screen edge; it is optional. |
The Fold8’s cover screen is 5.5 inches measured across the full rectangle, or 5.4 inches accounting for rounded corners; the main screen is 7.6 inches. Samsung lists their aspect ratios as 10:16 and 4:3, respectively. These are manufacturer specifications, not independent measurements of one-handed reach. Samsung Mobile Press describes the shorter, wider design as intended to make single-handed use more comfortable.
Turn on One-handed mode
Samsung’s general Galaxy-phone instructions give this path: Settings > Advanced features > One-handed mode. Because Samsung does not explicitly confirm the setting for the Fold8 in that guidance, use Settings search for “One-handed mode” if you do not see it.

- Open Settings > Advanced features > One-handed mode and switch the feature on, if available.
- Choose a launch action. Depending on your navigation setup, Samsung describes launching it with a swipe from the bottom edge or a double tap of the Home button.
- When the reduced window appears, use its side arrow to switch sides. Drag the bar to move the window vertically, or drag a top corner to resize it.
- Tap outside the reduced window to exit.
If the setting is missing, Samsung’s published steps do not establish whether it is available in your Fold8’s installed software; do not assume that changing another setting will make it appear.

Put frequently used apps within thumb reach
Samsung says the front-screen and main-screen Home screens are configured separately on the Fold family. Add shortcuts to each Home screen as needed so your most-used apps are easy to find in either position. To adjust icon size, Samsung gives the path Settings > Home screen. Its guidance does not list Fold8 cover-screen mirroring as supported, so set up the two screens separately rather than relying on a mirrored layout. Samsung’s Fold8 support instructions cover these Home screen options.
Add edge gestures with One Hand Operation+
One Hand Operation+ is an optional Samsung tool for assigning actions or apps to swipes from screen-edge handles. Samsung says it is available through Galaxy Store on smartphones and tablets, but its support guidance does not specifically confirm Fold8 compatibility.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check Flex mode availability on your Fold8
Samsung’s Fold8 open-and-closed support page explicitly says Flex mode is not available on the Z Fold8. A separate Samsung Flex mode support page lists the Fold8 as supported and gives the path Settings > Advanced features > Flex mode panel. Because Samsung’s pages conflict, do not treat Flex mode as guaranteed: check the setting on your device and follow the installed software’s available options.
