When an app is using either the camera or microphone, you’ll see a small green dot in the top right corner of your device's screen.

Maybe you have multiple apps opened and you're unsure which one is accessing the camera or microphone. There is a simple way to check this: when the green dot is on the screen, swipe down from the top to open the Notification panel, and then tap the green dot. You’ll see a pop-up notification with the app’s icon, as well as information about the camera or microphone. Then, you can find and close the app if you need to.
