Lisa Neilson, a British citizen, applied a gel screen protector on her Samsung Galaxy S10 device. However, to her shocking surprise, she witnessed that her left thumbprint which she has not registered could also be used to unlock the device. Going further, her husband who had not registered any of his fingerprints on the device could unlock the phone using his both the thumbs. This security flaw is all thanks to the gel screen protector which when applied to other Galaxy S10 device met the same fate.
During the launch, Samsung was very upbeat about its fingerprint scanning technology in Galaxy S10 phones and today Samsung has issued a statement in view of this, as below –
Regarding recent reports of a fingerprint recognition issue affecting certain Galaxy devices, we would like to inform our customers of the following information.
This issue involved ultrasonic fingerprint sensors unlocking devices after recognizing 3-dimensional patterns appearing on certain silicone screen protecting cases as users’ fingerprints.
To prevent any further issues, we advise that Galaxy Note10/10+ and S10/S10+/S10 5G users who use such covers to remove the cover, delete all previous fingerprints and newly register their fingerprints.
If you currently use front screen protective covers, to ensure optimum fingerprint scanning, please refrain from using this cover until your device has been updated with a new software patch.
A software update is planned to be released as early as next week, and once updated, please be sure to scan your fingerprint in its entirety, so that all the portions of your fingerprint, including the center and corners have been fully scanned.
Thank you for your patience and we will strive to continuously improve product and service experiences for our users.
