Speed up Fingerprint Sensor on Samsung Galaxy phones

If your Samsung Galaxy device is reacting slowly to your fingerprint, you might just be able to fix it thanks to a discovery by a redditor on /r/Android. The general idea is that instead of adding multiple fingerprints, you’ll instead set up only one fingerprint profile and mix and match fingerprints. Be warned however that there’s a slight possibility that doing this will make fingerprint unlocking less secure.
