The fingerprint scanner in the Xiaomi smartphone was used as a camera

Reddit user discovered a potential vulnerability in a Xiaomi smartphone: a man used a built-in

display fingerprint scanner as a camera.

The user claims to have found an opportunityview what image the scanner captures in the hidden system settings of the Xiaomi Mi 9T. The man showed in the video what actions she is taking to unblock the opportunity. He goes into the settings of the fingerprint scanner in the Locate sensor section. There a menu opens, which shows what the sensor "sees".

The Editor-in-Chief of XDA Developers has already noted thatthis option is a serious vulnerability that should be blocked. He noted that the problem lies not with the sensor itself, but with the software, which Xiaomi should not have left available to users.
