Use the fingerprint reader on your Xiaomi screen as a camera

A user would have managed to access the “camera” of the fingerprint sensor under the screen.

Readers of fingerprints under the screen have become a standard on Android mobiles, over facial recognition or other alternative unlocking methods, and now even some mid-range terminals carry it.

This method is based on a optical scanner that is capable of reading our fingerprints through the screen glass when we put our finger in the indicated area.

However, it has been discovered that they are not perfect, and this sensor can be used as a camera using the system’s hidden menus, let’s take a look!

Under-screen fingerprint readers have become a standard

If you have a fingerprint sensor under the screen, you can use its camera

Many top terminals, as well as many others in the mid-range segment and the cheap high-end segment today have a fingerprint reader under the screen, and a user with a Xiaomi Mi 9T has achieved access the camera from your fingerprint sensor.

As you can see in the video, by accessing the secret menus of your Xiaomi terminal, the user has been able to see what the under-screen fingerprint reader is seeing at the moment. Something that many users have described as a risk.

And it is that, although it is true that nothing is seen with the naked eye, it is a aspect that should not be accessible.

For now Xiaomi has not commented on the matter nor given any information on the roadmap with this type of sensors, so we will have to wait to see if this possible vulnerability is resolved.
