What you need to know

  • The ultrasonic in-display fingerprint sensors in the Galaxy S10 and Note 10 series phones can be bypassed using certain silicone protectors.
  • Samsung is advising that users remove these protectors for the time being and rescan their fingerprints.
  • A software update to fix the issue is expected as early as next week.

Some shocking news came out this week about the ultrasonic fingerprint sensors in Samsung's latest flagships. It turns out the sensor can be easily bypassed by using certain screen protectors or cases.

According to Samsung, this happens because of the patterns found in the silicone of the cases which causes the sensor to read it as a fingerprint.

This issue involved ultrasonic fingerprint sensors unlocking devices after recognizing 3-dimensional patterns appearing on certain silicone screen protecting cases as users' fingerprints.

What it doesn't explain is how can the sensor mistakenly recognize these patterns as your fingerprint in the first place. However, the statement goes on to say that a "software update is planned to be released as early as next week" to address the issue.
