About this app

Button Mapper makes it easy to remap custom actions to your volume buttons and other hardware buttons. Remap buttons to launch any app, shortcut or custom action with a single, double press or long press.

Button Mapper can remap most physical or capacitive keys and buttons, such as volume buttons, some assist buttons, and capacitive home, back and recent apps keys. Button Mapper can also remap buttons on many gamepads, remotes and other peripheral devices.

Root is not required for most actions, however some require an adb command from a connected PC if not rooted. Button Mapper does not work when the screen is off unless your device is rooted or you run an adb command.

A few examples of remapping you can do with Button Mapper:
-long press to toggle your flashlight
-remap your TV remote control
-press to broadcast custom intents, scripts or commands
-long press to open camera and take a photo
-double tap to launch your favorite app or shortcut
-double tap to open your notifications
-swap your back and recent apps keys (capacitive buttons only!)
-use your volume buttons to adjust screen brightness
-long press to toggle "do not disturb" mode
-and much more

Additional features unlocked in the pro version:
-Simulate keycodes (requires adb command or root)
-Swap volume keys on orientation change
-Default to ring volume on Pie or later
-Pocket detection
-Change back and recents buttons
-Customization of haptic feedback (vibration) on button press and long press

-Make sure Button Mapper accessibility service is enabled and allowed to run in the background
-Button Mapper does not work with onscreen buttons (such as soft keys or the navigation bar) or the power button.
-The options shown in the app depend on the buttons available on your phone. Not all phones have home, back and recents buttons!

This app uses Accessibility services. Accessibility is used to detect when the physical or capacitive buttons are pressed on your device so they can be remapped to custom actions to accommodate your needs. It is not used to see what you type. Button Mapper does not collect or share any of your personal information, it is safe and your privacy is respected.

This app uses the Device Administrator permission. (BIND_DEVICE_ADMIN)
This permission is used to lock the screen if the "Turn screen off" action is chosen. If you want to remove this permission, open Button Mapper, click on the menu (three dots in the upper right corner) and select "Uninstall"

I often listen to music with headphones, and, almost always, my volume keys are pressed in my pocket, causing full or no volume. This app allows me to stop long presses of the volume keys, even when the screen is off, ultimately stopping the issue. Very grateful for this app. EDIT: After a restart, this no longer allows screen-off actions. This is not the developer's fault, as Samsung restricts what people are able to do. It still works well beyond that.

It does what I wanted it to do, regain control of the ring volume to the volume buttons. I had trouble at first when I followed the instructions I found on a different website, and couldn't get the function to work. I emailed the developer and within an hour, I got a response that set me straight. If you are trying to get volume control to control ringer again after Android 9 update, enable the "Default to ring volume" option in Button Mapper Pro.

I love testing electronics. So, I've using a Doogee S90C. It's a great phone with terrible software. There are extra buttons. After two months, I decided that I would fix them. Several mappers were tried, do go. This one is one I used a while back with another Doogee. I reinstalled it and now I can navigate without touching the screen. One issue, it likes to sleep and the buttons will stop working. And I know to remove optimizers and run in background. I'm sure it is shutting off from a utility.

You will need to exempt Button Mapper from battery optimization. Your system is killing the service, see dontkillmyapp .com for more info
