Usually we use our thumb for unlock using fingerprint. When the first time register our fingerprint at SAMSUNG GALAXY A70, then try to register our thumb slowly while holding this phone. The thumb will scan rather tilted, it is not in an upright position, but however you should try to give little rotations while register the fingerprint.
SAMSUNG GALAXY A70 have three fingerprint slots to register. It mean we can use our left hand thumb or right hand thumb and some other different finger. But please try to register same finger thumb or only register one thumb for all 3 slots. Then most users will get more accurate and faster access to unlock security protections at SAMSUNG GALAXY A70.
