Google brings multimodal biometric unlocking to Pixels, Samsung gets faster fingerprint sensor

0

Several big names in smartphones have unveiled updates (or been rumored) regarding new biometrics within their devices.

9to5Google said Google intends to use its Pixel models’ under-display fingerprint sensor in conjunction with face unlock. SamMobile said Samsung will provide the Galaxy S23 Ultra with faster fingerprint sensors with a larger active area. Additionally, a patent spotted by Patently Apple suggests that the temperature sensor in Galaxy Watch 5 devices will not be functional when the device launches. And finally, Goodix has announced that Xiaomi’s new flagship smartphones carry the company’s fingerprint biometrics.

Multimodal biometrics for Google Pixel devices

Google is working on a version of Pixel Face Unlock that supports the under-display fingerprint sensor, reports 9to5Google.

According to the trade publication, the multimodal technology will lower the recognition threshold needed to unlock fingerprints when a face is at least partially recognized.

The technology seen by 9to5Google would not require additional hardware and is being tested on Pixel 6 and Pixel 6 Pro devices. For this reason, it could also be integrated into the Pixel 6a and other a-series devices.

The approach is supposed to be more battery-efficient while solving Google’s past face unlock issues.

The tech giant has yet to confirm that native face unlock will be coming to Pixel 7 devices.

The Galaxy S23 Ultra will sport improved fingerprint biometrics

Samsung’s upcoming Galaxy S23 Ultra could feature Qualcomm’s 3D Sonic Max fingerprint sensor, suggests a rumor carried by SamMobile.

From a technical point of view, the 3D Sonic Max is a larger and more precise fingerprint sensor than that of the Galaxy devices. Integration into Galaxy S23 Ultra devices would mean faster finger authentication and fewer false negatives.

Importantly, while the Galaxy biometrics software was hacked last March, the Galaxy S22’s fingerprint sensor was praised by experts for its accuracy, which is said to have surpassed fingerprint biometrics on the range. Pixel 6.

As for the Galaxy S23 series, Samsung hasn’t announced when it will introduce the devices, but chances are the company’s next Unpacked event will take place in the first two months of 2023.

Will Samsung reserve the 3D Sonic Max biometric sensor for its Ultra devices, or will the company integrate it into the base S23 models as well? Follow Biometric update to know more.

Galaxy Watch 5s temperature sensor has yet to receive approval

The Watch 5’s recently announced temperature sensor has yet to receive approval from Korea’s Ministry of Food and Drug Safety.

The news comes from a new report from the Korea Herald, which suggests that the Watch 5 range may not have a working sensor enabled when it launches next week (despite tech support to do so).

The delay in getting ministry approval may mean the Apple Watch 8 could be the first commercial watch to feature a temperature sensor.

Apple also beat out Samsung on sleep tracking features, which the Cupertino, Calif.-based company has supported for a few years.

Xiaomi Flagships Integrate Goodix Fingerprint Biometrics

The latest generation of Xiaomi phones carry fingerprint biometrics by Chinese consumer electronics vendor Goodix.

The company made the announcement in a video on Twitter August 11, showcasing a number of devices with biometric technologies.

These include a side-key capacitive fingerprint sensor for the MIX Fold 2 and an under-display optical finger sensor for the Redmi K50 Extreme Edition.

The video also shows that Goodix provides Xiaomi with a health sensor capable of measuring heart rate and blood O2 levels. It’s for the Xiaomi Watch S1 Pro and the VersaSensor with in-ear sensing and Force Touch for the Xiaomi Buds 4 Pro.

The announcement comes months after Goodix reported a sharp decline in revenue due to a number of factors.
