In just past July, the cell phone circle in addition to a variety of new machine releases and explosions there is a can not be considered a small scandal, Google Pixel 6a’s under-screen optical fingerprint BUG.

As a prototype of Android, this generation of the Pixel 6 series has been plagued with bugs from the very beginning of its release, ranging from automatic calls to a large number of strange sounds in recordings, which are huge and odd.

The most serious of these is the Pixel 6a’s under-screen optical fingerprint bug, which has resulted in many users having their Pixel 6a unlocked by an unregistered fingerprint, suggesting that the fingerprint recognition feature should be the same.

This bug not only comes from Google’s software issues but also has to do with the optical fingerprint recognition technology itself. Although optical fingerprint recognition is currently the most widely used fingerprint recognition technology in cell phones, due to technical reasons, optical fingerprint recognition itself has the disadvantage of low resolution and less information.

And compared to the optical fingerprint sense more reliable and fast ultrasonic fingerprint seems to be currently using not many manufacturers. However, according to the Digital Chat Station, Xiaomi’s ultrasonic under-screen fingerprint solution has also been tested for a long time and is expected to be used on the M series.

In previous news, the M series refers to the upcoming Xiaomi 13 Series to be released at the end of the year. In this regard, Digital Chat Station published a new report that the Xiaomi 13 Series will use optical under-screen fingerprints with new technology.

He said that Xiaomi hit the head of the two (Xiaomi 13 and 13 Pro) SM8550 (Snapdragon 8 Gen2) iterations of the flagship are optical under-screen fingerprint, ultrasonic has not yet landed. The new program unlocks speed and recognition rate have improved, with the new system optimizing the unlock animation and vibration feedback.

Ultrasonic fingerprint, as the name suggests, is the use of ultrasonic reflection, to achieve the identification of fingerprint contours through the screen, and even theoretically can measure the depth of the fingerprint bump, not only safer but also not afraid of interference from wet hands, dust and other stains.

In addition to the new optical under-screen fingerprint, there are several surprises in the Xiaomi 13 Series this time. Not only is it expected to debut in November with Qualcomm Snapdragon 8 Gen2, but the Xiaomi 13 series may also use Samsung’s new screen and UFS 4.0 flash memory.
