Galaxy S10 and Note 10 are finally receiving a fix for a huge Samsung security flaw

Own a Galaxy S10 or Galaxy Note 10? Well, it seems your device isn’t as secure as you first thought …at least if you have a certain type of screen protector installed.

Earlier this month, it was discovered the ultrasonic fingerprint sensor found on the latest top-tier flagship smartphones from Samsung is rendered useless at the hands of certain silicone screen protectors.

A British couple were first to discover the issue. Mother Lisa Neilson said she purchased a £2.70 screen protector from eBay which exposed the flaw.

Speaking to The Sun, she said: “This means that if anyone got hold of my phone they can access it and within moments could be into the financial apps and be transferring funds.”

The report in question prompted an investigation from Samsung that has since concluded its ultrasonic scanners can mistakenly read 3D patterns within a screen protector as a fingerprint. That means when any fingerprint is pressed on the scanner, it will identify the same pattern and therefore unlock the phone, even if the individual’s print is different.

Samsung has said it’s working on a patch for the flaw that will be released as early as this week. So if you’re still rocking a silicone screen protector, it’s probably worth downloading this fix as soon as possible.

As a quick reminder, the Galaxy S10, Galaxy S10+, Galaxy S10 5G, Galaxy Note 10 and Galaxy Note 10+ all leverage an ultrasonic fingerprint scanner to handle unlocks – as well as authenticate contactless payments.

Samsung’s small but powerful S10e is not affected. That’s because the device comes with a physical fingerprint reader on its side.

In a statement, Samsung encouraged S10 and Note 10 owners to remove any covers that can trick the sensor to restore their phone’s security.

The South Korean tech giant said: “This issue involved ultrasonic fingerprint sensors unlocking devices after recognising 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 portions of your fingerprint, including the centre and corners have been fully scanned.”

Samsung has not provided more specific timings for the patch’s release. However, will update you the moment it arrives.
