Problem description
termux-fingerprint does not trigger when I touch the fingerprint sensor. I allowed termux-api fingerprint permissions and all that, my device increases it's 'fingerprint allowed permission counter' every time I execute termux-fingerprint. I think the issue is very similar to #228

Steps to reproduce
Execute termux-fingerprint

Expected behavior
Return a JSON.
