One Hand Operation +

Samsung Electronics Co., Ltd.

About this app

With this app you can easily use your device with your thumb gesture.

When the feature is set, a thin gesture handle is added to the left/right side of the screen.
Swipe this handle to execute the defined functions. The default function is the most frequently used back button.

You can set various functions for horizontal/diagonal up/down diagonal gestures.
Once you get used to using short swipe gestures, you can set more features for long swipe gestures.

Depending on the size of your hand, the thickness of your thumb, or the shape of the bumper case you are using, different handle settings are provided to optimize gesture recognition.

The handle receives the user's touch event on top of the running app. It can interfere with running applications. Therefore, it is recommended to set the handle as thin as possible for gesture recognition.

If the touch interference is severe with running application such as game, you can set [App exceptions] in [Advanced Settings], then the gesture handles will not work when the app is running.

Currently available functions are as follows, and we plan to provide additional function upgrades.

Ratings and reviews

I think it's the number one app I install after a new phone or reset. You think you don't need it but once you've grown accustomed to it, it's hard to let go of it. Quick tools I think by far the most used function for me. So much easier then pulling down the notification bar. My fingers ain't that long lol. Quick tip: exclude this app when using the photo editor. You'll thank me.

This is one of the most featured apps for Galaxy phones, even though I was avoiding using newer versions of Galaxy devices because one hand operations has removed smart select for devices with oneUI 6.1 +, but once I did it with S26 Ultra, I found smart select, which is even more satisfying and more elegant one.

it is really good with all the extra stuffs added to it but the back swipe preview doesn't work with the app and wherever part of the screen the gesture is turned off for shows the swipe animation still and sweeping on the notification or which panel even after turning it off for those still shows the systems default back swipe arrows making it still work and on top of that ignores the customisation
