Galaxy Note 20 fingerprint scanner vulnerability repeats history

Samsung was one of the first smartphone makers that eyed in-screen fingerprint sensors but it was one of the last to actually adopt it. Even then, the technology it used ended up being more than disappointing. First introduced in its 2019 lineup, the fingerprint scanners that used Qualcomm's ultrasonic fingerprint sensor technology was proven to be susceptible to being fooled by screen protectors. It turns out, Samsung's 2020 Galaxy Note 20 phones were just as vulnerable to that trick.
