    Xiaomi 15 Series to Feature Ultrasonic Fingerprint Scanners

    A recent leak from Weibo user Smart Pikachu hints at a major upgrade in fingerprint scanning technology for the upcoming Xiaomi 15 series. The leak suggests that all three models in the lineup – the Xiaomi 15, 15 Pro, and 15 Ultra – are likely to transition from the optical in-display fingerprint scanners of their predecessors to ultrasonic fingerprint sensors.

    Advantages of Ultrasonic Fingerprint Sensors

    Ultrasonic fingerprint technology is becoming increasingly popular in flagship smartphones, with companies like Samsung integrating it into their top-tier devices. Unlike optical scanners that rely on light, ultrasonic sensors use sound waves to construct a detailed 3D map of the fingerprint. This method can provide several significant benefits, such as:

    • Enhanced Security: Ultrasonic sensors are believed to be more secure than optical scanners because they are less prone to spoofing attempts, such as those involving photographs or printed replicas.
    • Improved Performance in Various Conditions: While optical scanners may have difficulties with wet or dirty fingers, ultrasonic sensors are reputed to work more reliably across different conditions.
    • Faster Unlocking Speeds: Some findings suggest that ultrasonic sensors could offer quicker unlocking times compared to optical scanners.

    Despite these advantages, ultrasonic sensors are more costly to implement due to their enhanced accuracy and speed.

    Awaiting Confirmation from Xiaomi

    Although the leak from Smart Pikachu implies that all three Xiaomi 15 models will feature this upgrade, it’s crucial to remember that Xiaomi has yet to confirm this information. Additionally, the leak doesn’t specify which type of ultrasonic sensor might be used. Some manufacturers opt for a “single-point” sensor, while others use a larger sensor area for potentially quicker and more reliable unlocking.

    Launch and Speculation

    The Xiaomi 15 series is anticipated to debut in November, possibly powered by the forthcoming Snapdragon 8 Gen 4 chipset. As the official launch approaches, more information and validations regarding the fingerprint technology, as well as other features, are expected to emerge in the upcoming weeks.

    Huawei Unveils New Ultrasonic Fingerprint Sensor Patent Online

    Huawei has recently disclosed a patent for an innovative "ultrasonic fingerprint" sensor, signaling a potential shift towards creating their own ultrasonic fingerprint technology. This move is significant as many phone manufacturers currently rely on solutions from Goodix, which are constrained by Qualcomm's patents.

    Samsung's Influence on Ultrasonic Fingerprint Technology

    Samsung's Galaxy S10 stood out as the pioneer flagship smartphone to introduce the ultrasonic fingerprint sensor, setting a precedent in the industry.

    Patent Details and Technological Advancements

    The patent, officially titled "Ultrasonic fingerprint recognition module, system, and electronic device" (CN117058725A), outlines a sensor design that boasts enhanced fingerprint identification accuracy. This patent reflects Huawei's commitment to advancing fingerprint recognition technology.

    Huawei's Innovative Approach

    Currently, ultrasonic fingerprint sensors are predominantly featured in select high-end phones, particularly Samsung's premium S-series smartphones. However, these technologies face limitations due to Qualcomm's patent control. Huawei's new patent signifies a strategic move towards developing an alternative ultrasonic fingerprint recognition technology. By doing so, Huawei aims to reduce their reliance on external patents.

    Technical Breakdown and Operational Efficiency

    The patent intricately describes the sensor's construction, highlighting components like a stacked common electrode, a piezoelectric layer, and an array of pixel electrode units. These technical aspects delineate how the sensor functions in both transmission and reception modes, ensuring superior fingerprint data capture accuracy.

    Conclusion: Huawei's Future Direction

    Despite the complexity of the technical specifications, the essence of Huawei's new patent lies in their aspiration to cultivate their ultrasonic fingerprint technology. This strategic initiative hints at a future where Huawei will rely less on external solutions and pave the way for their innovative fingerprint recognition systems.

    Rumors suggest Xiaomi 14 Ultra to include enhanced four-lens coordination, satellite communication, and ultrasonic fingerprint technology

    Xiaomi, a leading name in the world of smartphones, is preparing to extend its flagship series with the upcoming launch of the Xiaomi 14 Ultra. This latest addition follows the successful releases of the Xiaomi 14 and Xiaomi 14 Pro, which have already made a strong impression in the high-end market. The forthcoming Xiaomi 14 Ultra is set to further enhance the brand’s reputation.

    Unveiling the Xiaomi 14 Ultra’s Flagship Features (Leaked)

    The Xiaomi 14 Ultra, which is yet to be officially revealed, is shaping up to be a formidable contender in the flagship category, boasting several high-end features. Based on leaks from the informant Smart Pikachu, the Xiaomi 14 Ultra is slated to include satellite communication capabilities, an ultrasonic fingerprint sensor, and telephoto macro features. Smart Pikachu also stated that Xiaomi has collaborated on a comprehensive solution designed to improve the performance and synchronization of its four focal lengths in image capture.

    The device is rumored to sport a quad-camera setup with 50MP sensors and variable apertures ranging from f/1.6 to f/4.0. Digital Chat Station has offered a glimpse into the impressive camera specifications of the Xiaomi 14 Ultra. The device is reportedly fitted with the Sony LTY900 sensor (officially announced today), an enhanced version of the Sony IMX989, featuring a 1-inch primary camera sensor.

    Security and Battery Life of the Xiaomi 14 Ultra

    In the security department, the Xiaomi 14 Ultra is reported to be trialing a single-point ultrasonic fingerprint solution, positioning it as a unique proposition in the Xiaomi 14 series. This technology is suspected to be based on the Goodix under-display ultrasonic fingerprint solution.

    According to earlier leaks, the Xiaomi 14 Ultra is also expected to be powered by a robust 5,180mAh battery, supporting both 90W wired and 50W wireless fast charging.

    Anticipating the Launch of the Xiaomi 14 Ultra

    The launch of the Xiaomi 14 Ultra is predicted to occur around April of the next year, in line with the release timelines of rival models such as the Vivo X100 Ultra and Huawei P70. As the launch date approaches, we can expect more information to surface, painting a more detailed picture of this eagerly awaited flagship device.
