Samsung phones have a camera access and microphone access toggle.
Here's what I get when I turn it off:
```
Turn off Camera access?
All apps will be blocked from using the camera. Apps
will still work, but they will only be able to access an
empty black screen. For example, you can still make
and receive video calls, but the other person won't be
able to see you.
```
```Turn off Microphone access?
All apps will be blocked from using the microphone
Apps will still work, but they won't be able to access
any sounds from the microphone. For example, you
can still make and receive calls, but the other person
won't be able to hear you.```
