Why is there a mark on the fingerprint position on the screen of the Xiaomi 15?
The Xiaomi 15 utilizes an advanced in-screen ultrasonic fingerprint sensor, embedded directly into the screen, allowing for a seamless and responsive unlocking experience. Unlike traditional capacitive fingerprint sensors, which require direct contact with the sensor surface, the ultrasonic fingerprint sensor works by emitting high-frequency sound waves to detect your fingerprint.
Due to the close contact between the fingerprint sensor and the screen, you can notice slight marks or impressions of the fingerprint module under certain circumstances. This is a normal occurrence and results from the nature of ultrasonic fingerprint technology. These marks are simply a byproduct of the sensor's design and do not affect the quality, performance, or functionality of the device in any way.
