    Read the usage history

If you do not see this option

• No Controls and alerts? On ours it is in the Privacy section of Security and privacy, below AI assistant activity. Google's Android help names the switches Camera access and Microphone access. Source: Change app permissions on your Android phone
• Want to block the microphone? Microphone access is the next switch on the same page. We did not try it. Source: Change app permissions on your Android phone

If this does not work

• Camera shows only black? Camera access is off. Tap Turn on in the Camera app, or switch it on in Controls and alerts.
• Camera failed message? Check Camera access first, then the other fixes: Camera failed on a Galaxy.
• Microphone not working? Microphone access may be off: Galaxy microphone not working.

About this guide

Camera access is one switch that blocks the camera for every app at once. Microphone access, just below it, does the same for the microphone.

The screenshots are from our Samsung Galaxy A57 with One UI 9 and Android 17 (build A576BXXU6BZIE), in Dark mode. We blocked the camera, opened the Camera app, and turned access back on from there. We did not test Microphone access.

Good to know

A green dot at the top of the screen means an app is using the camera or microphone: green dot on a Galaxy.

On a Pixel: turn off camera and microphone access on a Google Pixel.

In short: Settings, Security and privacy, Privacy, Controls and alerts, Camera access off, Block. Turn on again there or from the Camera app.
