Undocumented side effects of removing some biometric related packages on Samsung Galaxy S9+.

**Samsung Galaxy S9+**: \

**Describe the issue**
This issue isn't mentioned in the documentation so I'm assuming it isn't known.
I noticed a side effect after removing the following two packages:
com.samsung.android.bio.face.service
com.samsung.android.server.iris

The side effect of removing these packages is that biometric prompts in apps that use them (Aegis, Bitwarden, etc.) become delayed by about 5-8 seconds before appearing and the app gets stuck and locks up until the prompt appears. Once the prompt appears, everything functions like normal. Selecting 'Biometrics and security' in the settings app also locks up the Settings app for about 5-8 seconds but eventually loads and functions as normal.

**You have a solution?**
Only way to fix it that I know is to Restore the two packages. Even removing one of these two will cause this issue.

The issue describes undocumented side effects of removing specific biometric packages on a Samsung device. Look in the codebase for where these packages (com.samsung.android.bio.face.service, com.samsung.android.server.iris) are listed or handled, likely in a data file or module defining removable packages. Check if there's existing documentation about side effects. The task is to update documentation to warn users about the delay and app lock-up. Verify by checking the project's documentation structure and see where similar warnings are placed.
