OnePlus’ Face Unlock feature debuted with the release of the OnePlus 5T and has now made its way to the OnePlus 6. While it may bring about a flexible way to unlock the phone without the need to place your finger on a reader, it is still just as insecure as the facial security that comes with the Galaxy S9 and Galaxy S9 Plus. In a short video clip, it is revealed that a printed face was more than enough to unlock the OnePlus 6, revealing the holes that the company needs to plug in now with possible future updates.

The printed face was placed right in front of the person’s face who was attempting to unlock. The phone did manage to reject the facial data it was receiving at first, but the person was adamant to locate this flaw and sure enough, OnePlus 6 did manage to unlock itself.
