Description
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.

Additional options: -change the long press or double tap duration -delay initial button press for better double tap operation -disable Button Mapper while using specific apps -plus many more customizations
Troubleshooting: -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"

Comments on Button Mapper: Remap your keys for Android
★★★★☆Mike W· May 22, 2026
Does what it is expected to, the only nuance is that when I customize zello ptt on vol up or down long press, it continues until held again. The zello ptt on the main options screen works flawless, but it's both vol up and down, thus taking away my settings for single double and Long volume presses. If we could separate the main settings screen ptt to allow ptt vol up and a separate setting for vol down, this would hands down be the best app out there.

PLEASE CONFIRM the Moto AI button can be Remapped on the Razr FOLD 2026. I'll definitely buy it if so.
★★★★★Morgan Zolob· Feb 3, 2026
Worked great for me to map long pressing volume up to my flashlight on my pixel 9-fold. Also supports Shikoku so that the mapping works with the screen off as well.

Does work with the pro version. Wasted time trying map 1 button and then it pay for me
★★☆☆☆Zoe Erickson· Feb 27, 2026
My power button fell off, and now I can only turn my phone off / on by sticking something thin in the hole : (Is there really no way to remap Power? Not even replacing the useless Bixby button as a new Power button?

New button mapping worked one time only. After that even the mapping existed it does not respond. TCL Bluetooth remote.
★☆☆☆☆René Hollander· Jan 10, 2026
On my Sony TV I can't get it to remap the colored keys to execute HTTP POST actions for a Home Assistant webhook. After changing the action the UI doesn't update until I exit the customize menu for the button. And then whatever I do my HTTP POST action has no URL after coming back (and of course the button doesn't work). But the HTTP GET action is configured for the URL instead?? Also, it worked once for a day. But quickly broke and since then I have this bug. Cleared storage etc. but no luck.
