This is BY FAR the best tip I've ever seen. I haven't re-scanned fingers yet (you should) but the other 2 tips have garnered performance gains immediately! Life changing!! (lol, not really of course, but this is/was biggest gripe of this phone for me)
Essentially:
1. For a single fingerprint profile, scan both thumbs, switching back and forth (see video)
2. Go to Biometric preferences and turn off screen transition effect
3. Go to 'optimize battery usage' and change filter to 'All' scroll to 'com.samsung.android.biometrics' and turn off optimize.
Boom, that's it!
Give it a try and let us know if you see any improvements!!
