The Xiaomi 15 series is testing a special single-point ultrasonic fingerprint solution

After the official launch of the Xiaomi 14 Ultra last month, the Chinese brand is now working on its new series, the Xiaomi 15 series. The Xiaomi 15 series, which includes the Xiaomi 15, 15 Pro and 15 Ultra, is reportedly testing a unique single-point ultrasonic fingerprint feature . This technology is a significant improvement over the traditional optical fingerprint scanners found in most smartphones. This report comes from a popular and authoritative Chinese tech blogger, @DigitalChatStation (@DCS). According to him, the Xiaomi 15 series is testing “Huiding” single point ultrasonic fingerprint. This process will enter a new stage of the hardware NPI (New Product Introduction) in April. The term “Huiding” may mean that this solution is from the Chinese company Shenzhen Humidification Technology Co., Ltd.

Ultrasonic Fingerprint Scanners vs. Optical Fingerprint Scanners

Ultrasonic fingerprint scanners use high-frequency sound waves to create a 3D map of the user’s fingerprint, offering a higher level of accuracy and security than optical analogs. Optical fingerprint scanners, on the other hand, capture a 2D image of the fingerprint using light, making them generally faster but potentially more prone to fraud.

Single point ultrasound technology for fingerprints

The Xiaomi 15 Pro and 15 Ultra are believed to feature an ultrasonic fingerprint reader, a feature that was primarily found in several Samsung Galaxy flagship phones and more recently in the OPPO Find X7 Ultra and iQOO 12 Pro. Single-point ultrasonic fingerprint technology is a more secure solution than traditional optical fingerprint readers.

The report also reveals that despite the new feature, the Xiaomi 15 series will retain right curved double size strategy from the Xiaomi 13 and 14 series. The standard version still uses a small straight screen design. However, high-end models will stick to the curved screen design. There are also reports that the small screen version of this series is testing Goodix’s single-point ultrasonic fingerprint solution. Here’s what Goodix has to say about the solution

“Ultrasonic fingerprint solution with independent intellectual property rights provides a smoother and best unlocking experience. Goodix’s IN-DISPLAY FINGERPRINT SENSOR™ leads the evolution of bezel-less design. It’s the best-selling optical in-display fingerprint solution right now.”

Inquiries on Goodix’s official website reveal that the company has launched the GUM5228 ultrasonic fingerprint sensor. This is used for under-screen fingerprint recognition on flexible AMOLED screens. The the detection area is 5 mm x 5 mm and uses SPI interface for communication. Goodix claims that this ultrasonic fingerprint solution is based on CMOS sensor architecture and “has a higher signal-to-noise ratio” and the module thickness is 0.17mm.

Advantages of ultrasonic fingerprint scanners

Ultrasound fingerprint scanners can detect blood flow and heart pulses, making them more difficult to spoof with an image or dummy. They can be used to monitor heart rate, BMI and blood sugar levels, saving extra components and reducing the risk of screen burn.

Xiaomi 15 series specifications

From the reports available so far, the Xiaomi 15 series seems to be heading in a positive direction. The potential performance boost powered by the next-generation chipset is an enticing prospect for mobile tech fans. According to @DCS, this device will go into mass production in September. This means that the product release date in October may be earlier than Xiaomi Mi 14 series. However, we can’t rule out a potential November-December launch window. It probably reflects the Xiaomi 14 series release schedule.

Details on the Xiaomi 15 remain understandably scarce at this early stage. We can expect both the 15 and 15 Pro to boast the aforementioned Snapdragon 8 Gen 4 chip. The standard Xiaomi 15 is likely to retain its 6.36-inch screen size. However, the Pro variant boasts a subtly curved display with impressively thin 0.6mm bezels. This is a significant reduction from the 0.9mm bezels of the Xiaomi 14 Pro. Also, the Pro model’s display will offer a peak brightness of 1400 nits according to official reports. And a variable refresh rate ranging from 1Hz to 120Hz, potentially resulting in a 15-20% improvement in battery life.

While the rest of the specifications of the Xiaomi 15 series remain shrouded in mystery, early reports paint a fascinating picture of a potentially powerful and fast-approaching flagship lineup. As more information emerges, we can expect the talk around the Xiaomi 15 to intensify. The culmination is a potentially big launch later this year.

Conclusion

In conclusion, the upcoming Xiaomi 15 series seems to be a much-awaited addition to the smartphone market that boasts of innovative features and cutting-edge technology. The reported inclusion of a unique single-point ultrasonic fingerprint feature, coupled with the potential performance boost from the next-generation chipset, underscores Xiaomi’s commitment to providing a premium mobile experience to users.

The move to ultrasonic fingerprint scanners represents a significant advance in security and user authentication. The brand can now offer better accuracy and tamper resistance than traditional optical scanners. With the inclusion of this technology along with other rumored specifications such as improved display quality and battery efficiency, the Xiaomi 15 series has the promise of delivering an exceptional user experience.

While specific details about the Xiaomi 15 series remain limited, early reports hint at an impressive line-up of devices that will compete with other flagship offerings on the market. As anticipation builds and more information emerges, tech enthusiasts can look forward to the unveiling of the Xiaomi 15 series. This device is set to make a significant impact on the smartphone market upon its launch later this year.

The Xiaomi 15 series will bring innovative technology with the inclusion of ultrasonic fingerprint scanners and the Snapdragon 8 Gen 4 chipset. The single-point ultrasonic fingerprint feature is a significant improvement over traditional optical fingerprint scanners. It offers better security and reliability, especially in adverse environmental conditions.
