Face ID not working after iOS 15.6 update

[evol10375]

Did anybody try this magic finger to knock your Face ID out of working again ? Watch this Chinese guy's tip on

This is incredible!!! It works!!! I was supposed to go to the apple store tomorrow, my Iphone 13 pro max face id was dead from 3 days! I saw the video, I tried it, and with one swipe the face id was reborn!! Thanksss!!!

Update: Fix works only some hours... the good thing it's that now I know that it's an Hardware problem!
