THE Samsung is distributing an update to the Galaxy S10, Galaxy S10 +, Galaxy Note 10 and Galaxy Note 10+: it promises to correct the security flaw that unlocks the phone with anyone’s fingerprints. The problem with the ultrasonic sensor occurs when the user applies an incompatible film to the device screen.
Owners of the Galaxy S10, S10 +, S10 5G, Note 10 and Note 10+ are being alerted via a notification from the Samsung Members app. The company explains that the ultrasonic sensor can be confused with silicone films on the screen: it recognizes the texture of the material as if it were a fingerprint, allowing anyone to unlock the cell phone.
For this reason, the company will distribute a “biometrics update” over the next 24 hours; the notification on Android can only be removed when the update is installed. This is just a security fix, not a new version of Android (the beta of Android 10 with One UI 2.0 is in testing).
After installation, Samsung recommends re-registering your fingerprints, this time without a screen protector. The company explains that the fingerprints registered with the film “may contain incorrect information” and allow unlocking by anyone.
This update will only reach Galaxy devices with an ultrasonic reader, so the Galaxy S10e (with optical sensor on the side) will be left out. In addition, the cell phone must have fingerprints already registered to be covered by the update.
In the United Kingdom, some banks have taken security measures for the Galaxy S10. NatWest removed the app from the Play Store for these devices; while the Nationwide Building Society blocked the option to login via digital.
