Depending on the size of hand, the thickness of thumb, or the shape of the bumper case being used, various handle settings are provided to optimize gesture recognition.

The handle will receive user's touch above the running app. So, as long as the gesture recognition is possible, it is recommended to set handle to be thin.

And once you are fully familiar with the use of gestures, It is recommended that set max transparency.

In addition, when 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.

Experience the convenience of gestures on your phone and tablet with One Hand Operation +.
