Fingerprint and face recognition miss quite a lot on the note 10 plus making unlocking the device an annoying experience instead of a smooth one. I have enabled both for a smoother experience but sometimes even that is not enough for a smooth experience.
Fingeprints should take up more inputs at the time of set up as it can be seen clearly that the registered ones work better after 5-10 uses.
Display sensitivity should automatically increase while registering fingerprints, they are registered in a better way using that.
Regular patches/updates may help.
Also the brighen screen for face recognition should be automatically disabled at night time to avoid constant brightening of screen when you wake up in the middle of the night to check the time.
