Samsung says fingerprint security fix is coming as early as next week

Sunday, 20 Oct, 2019

"This issue involved ultrasonic fingerprint sensors unlocking devices after recognizing 3-dimensional patterns appearing on certain silicone screen protecting cases as users' fingerprints", Samsung said, referring to the in-screen fingerprint reader on its newest phones. For one United Kingdom couple using an low-cost "gel" screen protector (or case, it isn't immediately clear which), their cheap accessory compromised the phone's fingerprint recognition capabilities by allowing any finger to unlock the phone, eliminating the security offered by the in-display reader. The report states that the company may use scratch-resistant ultra-thin-glass to protect the display of the second-generation foldable phone. Samsung has since released an statement regarding the phones security in relation to these silicone screen covers. "We are building software that gets ultrasonic waves not to detect the patterns of silicon cases", said a company official, adding, "We will soon provide a software patch".

After she purchased a third party display protector, her husband managed to unlock her telephone with his fingerprint, although it wasn't registered. And best keep your phone out of reach of dodgy looking folks who want to pry on your phone's photos and contact list.

As The Sun reported earlier this week, a British woman bought a cheap gel-based screen protector off eBay, and she registered the fingerprint of her right hand.

Samsung has also stated that it will release a patch to prevent its recurrence in the future, which will be available next week at the soonest.

But it has a history of humiliating setbacks with major products, most notably a worldwide recall of its Galaxy Note 7 devices in 2016 over exploding batteries, which hammered its reputation.

After all, there's a big difference between an unresponsive or completely nonfunctional fingerprint recognition system and one that can't distinguish the rightful owner of a phone from a possible intruder just because something is covering up the screen.

Samsung Electronics is taking steps to respond to the fingerprint security problem of its flagship Galaxy S10 and Galaxy Note10 smartphones.
