In General, I saw recently such a thing: when you enter a pre-stored fingerprint, the phone rasplachivaetsya in "the second space". But if you send a normal print, then it will work in native mode. It is very difficult to explain, but I wonder how is it possible to turn on your device?
I jabbed the thumb of the right hand into the sensor of the fingerprint, the phone is unlocked and I see apps like instagram, VK and anything else
But if I already jabbed a forefinger, you'll see a very different application.
Are there any ready-made solutions, you can even (if any) module for magisk?
