Control your phone or tablet more easily with just one hand.

Small gesture handles will be displayed on left/right edge of screen. 
By swiping this handles, configured actions will be executed.  below is default action.

- Short horizontal swipe : Back key.
- Diagonal up swipe  : Recents key. 

You can set various functions on horizontal / diagonal up / diagonal down direction gestures. As you become accustomed to using short gestures, you can set up more functions on long gestures.

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

 - Back key
 - Home key
 - Recent key
 - Menu key
 - Previous app
 - Forward ( web browser )
 - Open notification panel 
 - Open quick panel 
 - Screen off 
 - Assistance app 
 - Screenshot 
 - Floating navigation buttons
 - Pull screen down
 - One-handed mode
 - Flashlight
 - Start application
 - Task switcher 
 - Quick tools 

Depending on the size of the user's hand, the thickness of the 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 to enable [Quick action] on [Advanced settings].

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 +. 

Thank you.

Good gestures navigation app, needs a bottom gestures area.
please allow us to reorganize the volume and brightness sliders module under the Quick tool. I prefer the brightness slider as far to the bottom as possible for fast and easy reach/access.
this app is amazing, a must have. but what's really annoying is if you have One Hand Operation disabled for certain apps or disabled when keyboard is in use, it's also disabled on the lockscreen if you leave said apps open. that's quite frustrating when im so used to it working except those couple of times I leave said apps open. please fix this so I could use the gestures on my lockscreen, even though a disabled app/keyboard is under my lockscreen. thanks for the great app otherwise! edit: it isn't disabled on my lock screen. but when I lock my phone on a disabled app, it's disabled.

Dear customer, You can use gesture on lock screen Please turn off "Hide on lock screen" switch on "Advanced settings", then you can use it on lock screen. Thank you.
Perfect app that should be on every phone.
Love the CUSTOMIZABLE gestures that Samsung is allowing through this app. I used a different app up until I heard about 1HandOp+ and Good Lock. Really like the quick tools menu. Love that it allows Apps to be open via gestures! PLEASE ADD AN OPTION FOR SHORTCUTS TO BE OPEN WITH GESTURES AS WELL. Other than missing shortcuts; great functionality and ease of use. Works amazingly. Keep it up👍
This app just makes my life so much easier!! 👍
Amazing functionality. Now my favorite feature of my Galaxy. Things like this are what are keeping me from switching to another phone.
This really is amazing! It is much more helpful than I thought it would be
Great app. Add more options on quick tool such as the pin app feature
LOVE LOVE LOVE this!!!!!! No more hand gymnastics for me lmao
Uuugh.. Why did you add so much on the quick tools section.. I liked the simple design before the update.. PLEASE BRING BACK THE MUTE TOGGLE
The last thing I was truly missing from iOS and my iPhones was the universal back gesture from the left hand side of the screen. Thnk u!
Does what the app is designed to do, but I wish the recent app switching animation were different based on swipe side. Left or right side.
Why just take list view away? Coule we get it back as an option?
