How to Revoke Microphone Access on Android (Step by Step)

The fastest way to stop every app from accessing your microphone is the system-wide toggle. Pull down the Quick Settings panel twice and tap Microphone access — it turns the hardware mic off at the OS level, so no app, including pre-installed ones, can hear anything.

The global microphone toggle

The toggle survives reboots and shows a small icon in the status bar when active. Phone calls still work because the calling app prompts you to re-enable it for the duration of the call.

Per-app microphone control

For a more surgical approach, open Settings > Security & privacy > Privacy > Permission manager > Microphone. Anything other than your calling, messaging, and voice-assistant apps should be set to "Don't allow" or "Ask every time".

Reading the green mic indicator

Whenever any app uses the microphone, Android paints a small green dot in the top-right corner. Pull down Quick Settings and you'll see which app is responsible. If you don't recognise it, revoke immediately.
