Button Mapper

Tired of your volume keys doing nothing but adjusting sound? Button Mapper lets you reprogram your phone’s physical buttons to do exactly what you want. Whether you want to launch your favorite app with a double tap or toggle your flashlight with a long press, this tool puts custom shortcuts right at your fingertips—no root access required.

Remap Physical Buttons Without Rooting Your Phone

Button Mapper works with physical and capacitive keys across a wide range of devices. From Samsung Galaxy home buttons to Sony camera keys, and capacitive navigation buttons on ASUS, HTC, OnePlus, and Xiaomi phones, the app detects your hardware and lets you reassign actions instantly. You can configure single presses, double taps, and long presses separately, giving each button multiple personalities depending on how you press it.

Creative Ways to Use Button Mapper on Your Device

Imagine long pressing volume down to flip on your flashlight, or double tapping your home button to open your go-to app. You can turn off the screen with a long press of the home key, instantly call your best friend by holding volume up, or check notifications with a double click of the back button. Some users even swap their back and recent apps keys or use volume buttons to adjust screen brightness. The possibilities are pretty much endless.

Which Hardware Keys Does Button Mapper Support?

The app supports home, back, recent apps, volume up, volume down, and camera buttons depending on your device. Keep in mind that back, recent apps, and camera button support requires the pro version. Onscreen navigation bar buttons and the power button aren’t compatible, and the app won’t run while your screen is off.

Actions You Can Assign to Every Button Press

• Launch any app or shortcut
• Disable a button completely
• Trigger home, back, or recent apps
• Switch to the last app
• Turn the screen off
• Toggle flashlight
• Open quick settings
• Show notifications
• Bring up the power dialog
• Take a screenshot
• Control music playback (previous, next, play/pause)
• Adjust volume or brightness
• Toggle do not disturb mode

Free Version vs Pro Upgrade: What’s Included?

The free version lets you remap the home button and volume keys. If you want support for the back button, recent apps button, and camera button, you’ll need the pro upgrade. Pro users also get lockscreen peek, homescreen lock, four themes, customizable haptic feedback, and the ability to bypass Button Mapper in specific apps.

Button Mapper Respects Your Privacy

This app doesn’t collect or share your personal information, it doesn’t monitor what you type, and it contains zero advertisements. Your button configurations stay on your device.
