Spearheads Trouble: Samsung's sophisticated biometric scanners are breaking down and in need of software updates

Original article: Samsung chose unique ultrasonic technology for the biometric scanners built-in under the screen on its top devices - and now it seems that a simple protective sticker is enough to break their credibility

Sometimes it seems that overly sophisticated technology in mass consumer products can lead to the opposite effect and cause insignificant headaches for the manufacturer of choice. Google experienced this with Its biometric face scanner raises eyebrows because of its ability to access the Pixel 4 devices even when the user closes their eyes, And now also Experiencing something similar with the families model S10 and Note its 10 now.

Samsung was the pioneer in using built-in fingerprint scanners under the screen based on Supersonic, instead Optically on all other devices on the market. Frequent radio waves that are inaudible to the human ear were sent from the scanner to the finger attached to it and returned to the scanner depending on its physical structure, so that the user can also be identified in a situation where his hands are wet or dirty - which is not usually true in common optical scanners.

Referred to its fingerprint scanners as one of the significant advantages in the market when it comes to reliability - but it turns out the reality may be a little more complicated

The scanners on leading devices , A joint development with a company Have been able to prove themselves quite badly in practice - but now it turns out that they have a pretty serious security flaw that allows almost anyone to access the device in a situation where a silicone shield exists over the display panel. The same shield appears to create 3D reflections that "confuse" the advanced biometric sensors, causing the lock screen to open even when it is actually misidentified.

Note 10 models are also not immune to the problem - this is in contrast to the company's cheaper devices with optical scanners under the screen

This problem quickly went viral, prompting developers of various Android applications to announce the temporary fingerprint identification feature on devices S10 and Note 10 to minimize the potential for breach damage.

In Samsung itself Provided a formal notice In which they confirm the existence of the problem, and ensure its correction as soon as possible through a software update. And until that happens? The company recommends that users stop using screen protectors, erase the fingerprints stored in the system, and save biometric information, without the cover, not really an effective solution for those who do not want to compromise their recently acquired physical protection.

Is the technology on it? In recent years will you be pushed aside? We hope not, at least until we get more details about the technical causes of the suddenly discovered problems

Samsung may well be able to overcome the strange bug in remote update in the near future (such an update seems to have begun a gradual distribution to devices in recent hours), but the negative impact of perceiving flagship devices from the company as unsure and unsecured would seem to be quite difficult to change. Now it remains to be wondered whether this saga will cause high-end fingerprint scanners to disappear from the market in the near future (or even permanently), or that Samsung will not give up this interesting technology so quickly.

updating: More information indicates that the security issue on devices Created only when users purchased a new fingerprint for a system with an unrecognized and officially approved type of protective coating - so that the information received in the sensor was for the refunds in the shield itself and not the user's finger above it, so the same refunds were there at any given time and enabled the device to be opened at a time. In the same way, removing the problematic protective cover over a locked device could result in a situation where the device cannot be opened by a fingerprint at all (although there is a physical password backup for exactly such situations, as is well known).

Samsung has announced that it has started distributing its software update for the handsets S10 and Note 10 is supposed to prevent the mess, in the Korean market first and with planning for a gradual global distribution in the near future (some consumers in Israel have already received it for their device, it seems) - but the company continues to make it clear that they do not recommend the use of unadjusted and unapproved protective covers.
