Recently, on Redditor demonstrated how he turned his smartphone’s optical fingerprint sensor into a camera using a third-party application. Although the imaging quality was pretty horrid since optical fingerprint sensors are not designed to focus beyond the glass on which your fingertip rests, it did raise some major security concerns.

The user accessed live image feed using the optical sensor by installing an app called Activity Launcher that gives access to hidden activities within devices, such as access to calibration menus, factory tests, and other demos.

This discovery was demonstrated by XDA-Developers editor-in-chief Mishaal Rahman on Twitter and who also pointed out how OEMs should be vigilant enough to not leave bugs like this.
