What to do if you can’t find which app is using microphone and camera

Hi Cboy1961,

Thank you for using the Apple Support Communities! You can review or change the access to the microphone and camera on your iPhone by following the steps below:

Control access to hardware features on iPhone

1. Go to Settings  > Privacy & Security.

2. Tap a hardware feature, such as Camera, Bluetooth, Local Network, or Microphone.

The list shows the apps that requested access. You can turn access on or off for any app on the list.

Hope this helps!

Have a great day.

Open the Control Center and at the top it will display the app that last used either the microphone or the camera.
