Samsung Plans to Patch Major Galaxy Security Hole Next Week

  Samsung Plans to Patch Major Galaxy Security Hole Next Week Samsung Electronics Co. said it will issue a software update early next week to address a major security vulnerability that’s emerged on the company’s flagship Galaxy smartphones, the latest technological mishap for the world’s largest smartphone maker. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.

Qualcomm ' s 3D Sonic Max is a new type of ultrasonic sensor that should cover 17x more of the screen - will it appear in the Galaxy S11? Vivo packed it into the Apex concept phone it showed off earlier this year, with an in - display fingerprint sensor that covered almost the full screen and allowed

Qualcomm has announced a second-generation version of its ultrasonic in-display fingerprint sensor, the 3D Sonic Max, that promises to fix the issues with the original 3D Sonic Sensor by offering a sensor that’s 17 times bigger. The 3D Sonic Max is so big, in fact, that it can read two fingerprints at once for extra authentication, via Engadget.

The company’s first-generation ultrasonic fingerprint reader, the 3D Sonic Sensor, promised improved reliability and security over existing optical in-display fingerprint readers. Despite a high-profile debut in Samsung’s Galaxy S10, the first-generation 3D Sonic Sensor was plagued by issues, including problems getting the smaller sensor to read prints accurately, slow speeds, and a glaring security hole caused by some types of screen protectors that was only fixed in October.

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

  Samsung says fingerprint security fix is coming as early as next week And advises removing silicone screen protecting cases for nowAccording to the company, the issue is caused by the phones’ ultrasonic fingerprint sensor incorrectly reading 3D patterns in the screen protector as fingerprints. As a result, any person could then unlock a phone wrapped in such a case, creating a security issue.

How ultrasonic fingerprint scanners work. Qualcomm ’ s 3D in - display ultrasonic fingerprint scanner is based on what used to be called Sense ID. Fortunately, there’s no need to swipe, just touch the finger to the sensor like the top of the line capacitive fingerprint scanners.

Qualcomm has announced the next generation of its in - display ultrasonic fingerprint sensor, dubbed 3D Sonic Max. The new sensor is, remarkably, 17 times larger than the original sensor area. That larger area enables simultaneous two - finger authentication for heightened security

Qualcomm looks to solve problems in the first-gen 3D Sonic Sensor

The new sensor looks to address those issues, thanks to being vastly larger: where the old sensor measured 4mm x 9mm, the new 3D Sonic Max is 20mm x 30mm, or 17 times larger. According to Qualcomm, that should help solve most of the earlier problems. The bigger sensor makes it far easier to position a fingerprint (to avoid the positioning issues).

And in an interview with CNET, Alex Katouzian, SVP and general manager of mobile at Qualcomm, noted that the new 3D Sonic Max should avoid the screen protector problems by capturing a clearer complete fingerprint when reading due to the larger scanner size. The option to require two simultaneous fingerprints to scan together also should help increase security options.

Samsung warning: Galaxy S10 and Note 10 owners should remove their screen protectors now

  Samsung warning: Galaxy S10 and Note 10 owners should remove their screen protectors now Samsung's new high-tech fingerprint reader on the latest Galaxy smartphones has a major flaw: It can be fooled by the residue left by your fingers on a screen protector.

The Qualcomm 3D Sonic Max is an improved in-screen ultrasonic fingerprint reader that’s faster and much larger than the previous-generation. Qualcomm ’ s first under- display fingerprint reader , the 3D Sonic Sensor, didn’t exactly live up to its hype. Unlike optical fingerprint sensors that use light

Qualcomm ’ s in - display fingerprint technology has already been employed by Samsung in the Galaxy S10 and Galaxy Note 10 family. However, the chipmaker has announced a new version of its reader called 3D Sonic Max. It is 17 times larger than the previous generation, is faster, and it can also read

One thing that won’t change, though, is the speed. According to Katouzian, scanning a fingerprint will take roughly the same amount of time with the new sensor as it did with the old one.

We’ll have to put the new 3D Sonic Max through its paces to see whether it actually solves the problems of the original 3D Sonic Sensor. There’s still no word yet as to which companies will actually be using the 3D Sonic Max in devices, although there should be more news on that sometime in 2020. One potential customer could be particularly interesting: early rumors claim that Apple is exploring using Qualcomm’s tech to add an in-display fingerprint reader to the iPhone as early as next year, per MacRumors.
