On my. Ew Samsung Galaxy Note 10plus 5g edition I can see the fingerprint sensor and ribbon cable through the screen. I'm not sure if it's the lighting of my surrounding or if it is a software issue. I've updated to the latest patch. (Always up to date) and the fingerprint sensor is visible only sometimes after update/patche(s)
The fingerprint sensor will be visible at certain angles and usually when there is a bright light source facing it.
