What it is

According to olorin, it's a MediaTek’s default fingerprint app (and he removed it).

Can someone confirm what this package does?

Remember that any pre-installed apps you don't actually need just increase the surface attack.

Any app co-located on the device could modify a system property through an exported interface without proper authorization.

Vulnerability found in 2019

Commands

adb shell pm uninstall --user 0 com.mediatek.wfo.impl

To put it back:

adb shell cmd package install-existing com.mediatek.wfo.impl

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.
