To offer a cleaner design to users, phone makers started baking in-display fingerprint sensors into their devices. It tucks away the fingerprint sensor under the display, thus, eliminating the need for a physical one on the rear or front. Now, a creative Redditor found a way to convert the in-display fingerprint sensor of his Xiaomi smartphone into a working camera. Yep, you heard that right!
As you can see in the video, he opened the Activity Launcher app on his device and searched for the fingerprint sensor. Then, he opened a new page by tapping the “Locate sensor” button. On this page, we can see a tiny viewfinder showing what the digital camera of the fingerprint sensor sees.
