Hi, thanks for that demo app, but unfortunately I can't reproduce the crash with it. Looking at the code I'd advise to not trigger the fingerprint UI before the page has loaded, so ngOnInit is probably not the best place. To check if that's the problem, please test triggering the scanner from a button.

Also, I can't find useCustomAndroidUI in your code, so I'm not sure we're looking at the same thing.

Thanks for the answer, i'll try your tips and i'm back later with result.
