I don't know as I've never used it myself. It does work as additional home button, though.Is there anyone else having issues with the fingerprint reader? As soon as I try to set it up, the app freezes. Didn't happen with an older version (Feb 2020 or so...).
Does it work again if you flash the old version?
Did you flash OpenGAPPS in a version bigger than pico? There's been a report a couple weeks back stating that might cause trouble as it replaces LOS system system functions.
