How To Resolve Installation Bugs One Hand Operation +

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.

By far and away the most useful application you can install when you have a large phone. The level of customizability and the reliability is top notch. Now that I've gotten used to the gestures as I have set them, getting to anything I need is a piece of cake, not to mention the envy of any iPhone user. Had this on my note 8 & putting it on my note 10 is a no brainer.

This app is just gold if you're even sort of a power user on your Android. Especially on these big phones like the S2X ultras, I like to be able to access certain things like flashlight, auto rotate, close app, etc. You can customize every aspect and block it on certain apps, say, video. Been using this a few years now and I've never had it not work.

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.
