Unfortunately, no integrated option allows you to disable yourAndroid devices cameraand mic.
Sure, you might cover it up with tape, but that idea doesnt sound too appealing.
But to access this option, youll need to enable Developer Options.
You should see theDeveloper options near the bottom.
Select it and swipe down slightly until you see theQuick controls developer tilesoption.
The last option down is going to be theSensors offoption.
Tap on it to turn it, and from now on, your mic and camera will be blocked.
No apps can access it.
it’s possible for you to test this out by trying to useGoogle Assistant.
Youll see that even if you say, OK Google.
nothing will happen since Google wont have access to your mic.
