Camera Inaccessible When Switching Cameras on Android Devices

## Description:
On Android devices, when attempting to switch the camera (e.g., from rear to front) using the QR-Scanner library, the camera view shows a black screen with a message indicating "Camera inaccessible." This prevents users from successfully switching to the desired camera for scanning.

## Steps to Reproduce:
- Open the wallet on your Android device.
- Click on the QR-Scan icon.
- Attempt to switch the camera (e.g., from rear to front) using the camera switch button.
- Observe the black screen and the message stating "Camera inaccessible."
## Expected Behavior:
When the camera switch button is clicked, the app should seamlessly switch between front and rear cameras without any errors or loss of camera feed.
