A series specs fingerprint scanners

[arya0511]

I like that Samsung is implementing it's optical in screen fingerprint scanner with the galaxy A50 ...thought the other two in the series get normal scanners ...but they aren't too outdated and solve the purpose well

optical is the same speed as ultrasonic
