Key Mapper

Struggling With Buttons That Just Don't Work For You?

You know the frustration: you tap a key on your phone, and nothing useful happens. Maybe you want your volume button to launch the camera, or your fingerprint sensor to open your favorite app. Standard Android simply won't let you remap those controls. That's exactly where this tool comes in. You get the power to assign any action—apps, shortcuts, system controls—to almost any hardware button on your device. No more wasted taps; every press does exactly what you need.

Take Full Command Of Every Physical Button

This app acts as your personal button manager. You assign specific functions to keys like volume up/down, power, camera, or even the Bixby button on Samsung devices. The configuration is straightforward: you pick a button, choose a trigger condition (single press, double press, long press), and then select an action. You can launch an app, run a shortcut, toggle WiFi, open the notification shade, or even simulate a key press. The depth of customization means you control the behavior for every scenario.

The tool also supports advanced conditions. You can set actions to trigger only when the screen is on, off, or in landscape mode. For example, you could make a long press of volume down activate the flashlight when the screen is off, but change it to skip a track when music is playing. This context-awareness makes your phone smarter and more responsive to your actual needs.

What Makes This Setup Powerful

• Supports almost any hardware button – Remap volume keys, power button, camera button, Bixby key, and even headset controls. You are not limited to just a few options.
• Multiple trigger modes – Single press, double press, long press, and even triple press. You get up to three different actions from one button.
• Context-based actions – Set different behaviors depending on screen state, app in foreground, or time of day. Your phone adapts to how you use it.
• Quick launch for apps and shortcuts – Open any installed app, a specific activity, or a custom shortcut directly from a button press.
• System controls at your fingertips – Toggle flashlight, switch audio profiles, adjust brightness, take screenshots, or control media playback without touching the screen.
• Works without root – The app uses Android's accessibility service to intercept key events. No rooting required, though root access does enable some extra features.
• Low resource usage – Runs quietly in the background without draining your battery or slowing down your device.
