Button Silencer

Faulty inline remotes can generate phantom volume, media, assistant, or headset-hook presses. In the worst case, a ghost headset click can answer or end a call. Button Silencer blocks those controls while leaving the phone's physical buttons alone.

Protection model

- Screen on: Android Accessibility filters headset keys before apps receive them. - Screen off: Shizuku provides the privileged path used for headset input protection. - Selected headset: its safe remote-control input nodes can be exclusively guarded before Android handles their button events.

Call-capable headset keys are treated as safety-critical while protection is enabled. The app only reports full protection when both the screen-on path and the selected-headset screen-off guard are ready.

Setup

1. Install the APK. 2. Enable Button Silencer in Android Accessibility settings. 3. Start Shizuku and grant Button Silencer permission. 4. Turn on Headset button protection. 5. Connect the affected headset or USB DAC, tap Scan headset, and select it.

After a reboot, Shizuku must be started again before screen-off protection can return.

Requirements

- Android 8.0 (API 26) or newer - Shizuku 13 or newer for screen-off protection - Accessibility permission for screen-on filtering

Privacy and behaviour

Button Silencer has no network permission, no analytics, no ads, and no account system. It does not claim USB interfaces, modify Android key-layout files, use a wake lock, or run a permanent polling loop. Diagnostic logging is off by default and stays in memory for the current app session.
