iOS App stops responding after three to five successful barcode readings

[dristea]

I just implemented BarcodeScanner with Cordova - iOS 4.2.0

1. I am getting many deprecation warnings.
2. Several output warnings regarding the AVCaptureVideoPreviewLayer.

Is there a quick fix for this? Should I downgrade cordova?

Did you manage to find a solution to this? Although it isn't affecting my app but I'm a little worried about it.

When opening camera, the image just freezes. The only thing to solve it is to switch to front-camera, which then returns a catch error, then back to rear camera, which scans the code, but the result is not, since it was returned by switching to front in the first place.
