Wow, you still don't get it.

Show me a Linux phone that is actually configured to unlock with both biometrics and pin, then you have proven that Linux is relevant.

I don't care about what is technically possible, I care about it actually being done.

I am not even asking if it is easy to setup or simple to use, I am just asking you to prove that it can be done on a Linux phone.

I am just asking for a proof of concept running on a Linux phone.

I am giving Linux the best possible chance here, the bare minimum.

The tasks I want to see done on a Linux phone is the following:

1. Prompt for a fingerprint, face scan, or any quick biometric.
2. Once passed the biometric prompt successfully, the phone should prompt for a pin.
3. once passed both prompts the phone should unlock.

I love Linux, I have been a Linux sysadmin for almost a decade and used Linux on and off for almost twenty years. I daily drive Windows due to work and gaming, but am considering switching to Linux at home when Win10 goes EOL.

But unless you can show me a Linux phone configured as described above then Linux is not the answer.

For the time being I wish you a happy midsummer.
