Button Mapper

Button Mapper is a customization utility that remaps hardware and accessory keys to custom actions.

Button Mapper helps when default buttons do not match your routine on a phone, tablet, TV remote, or gamepad. It lets you change what a press does so common tasks sit under your fingers, and most changes work without root. Advanced options are available through a simple ADB setup or root if you need them, and the app focuses on privacy. To get started quickly, download the Button Mapper APK and follow a short setup inside the app.

Button Mapper features

Remap physical and capacitive buttons

Button Mapper can detect and remap most physical and capacitive keys on your device. This includes volume keys, home, back, and assist buttons, along with many accessory buttons on keyboards, headsets, and game controllers. It also supports Android TV and Google TV remotes on many models.

Choose single, double, or long press

You can assign different actions to a single press, a double press, or a long press. Pick app launches, shortcuts, and controls like flashlight, screenshots, camera shutter, quick settings, media playback, or opening the notification shade. This setup gives you flexible control without changing your home screen layout.

Core tools without root, extras with ADB or root

Most remapping works without root so you can use it on a typical device. If you want extras such as remapping while the screen is off or simulating keycodes, Button Mapper provides an option that uses a one time ADB command or root. You can enable these additions later as your needs grow.

Pro options for advanced users

Pro features expand what the app can do for more specialized setups. You can simulate keycodes, swap volume keys when the device rotates, adjust haptic feedback, and apply themes. Button Mapper Pro also supports broadcast intents, running scripts, pocket detection, and custom keycodes for deeper control.

Privacy and performance focused

Button Mapper is designed with privacy and efficiency in mind. It uses Accessibility and Device Admin only for detecting presses and locking the screen, and it does not collect personal data. The latest version stays responsive while keeping battery impact low.

Before you download Button Mapper

• Compatibility limits: it does not work with on screen navigation buttons or the power button. Some system keys are restricted by the device maker.
• Device variability: behavior can differ by brand, Android version, and firmware on phones, tablets, and TVs. Certain OEMs restrict remapping of specific keys.
• Permissions: Accessibility is required for detecting button presses. Device Admin is used only for screen lock actions. The app does not collect personal data.
• Free vs Pro overview:

  • Pro: simulate keycodes, send broadcast intents, run scripts, pocket detection, themes, haptic tuning, volume key swap, and custom keycodes.

Android TV and Google TV notes

Many TV remotes are supported, including volume, navigation, and some app keys. However, streaming service buttons may be locked on certain TVs and may not be remappable. Where the system allows changes, you can assign those keys to open your preferred app or trigger a shortcut. Results can vary across brands and software builds, so test your remote after installation.

How to use Button Mapper

After you download Button Mapper, setup takes a few minutes. The process is the same on phones, tablets, and many TV devices. Follow these steps to create your first mapping.

1. Open Button Mapper and grant the requested permissions. Enable the Accessibility service and allow Device Admin if you plan to use screen lock actions.
2. On the main screen, select the button you want to change and turn on the customize option. Press the button once if the app asks you to detect it.
3. Choose the press type. You can set a single press, a double press, or a long press to behave differently.
4. Select an action or an app. For example, pick flashlight, screenshot, camera shutter, quick settings, music controls, brightness or volume adjustment, last app, or open a specific app or shortcut.
5. For advanced behavior, open the advanced settings section. To remap while the screen is off, connect to a computer and run the one time ADB command shown in the app or use root, then return and finish assigning your actions.
