I'm trying to make a qr code scanner with the expo-barcode-scanner in react native. Everything works fine but when I exit the application (It still run in the background), the camera symbol in the top right corner stays there like this:

Example

I just copy/pasted the example from expo and It's still do the same thing.

Any suggestions?

I'm not sure but I think that I need to unmount somehow the permission?

I had the same issue with navigation.

After unmounting the component the problem disappeared. It is even described in the Expo documentation

When using navigation, the best practice is to unmount any previously rendered BarCodeScanner component so the following screens can use their own BarCodeScanner without any issue.

Hope it will help!
