When I use the scan function to setup my own external node, pressing the back-button will close the camera as expected without having to scan a QR-code. But when I press the scan button in the top right corner of the app, the camera does not respond to the back-button and the only way is to either scan a QR code or press the little qr-code symbol under the camera view, which overwrites the camera by opening up the send form.

Edit: The same behaviour when using the scan QR camera for opening a new channel.

Expected Behavior

After activating the scan function from the top right corner, pressing the back button should close the camera.

Current Behavior

The camera opened when pressing the QR code button in the top right corner is stuck until a QR code is scanned.

Steps to Reproduce

1. Press the little QR code symbol in the top right corner.
2. The camera opens and awaits scanning a QR code.
3. The back-button is unresponsive.

This will require hacking the QR Library to handle the back button and will be addressed in a future build.
