Copy&paste from someone else

(thanks really much - worked on my 13 pro max)


Turns out, the problem was with content restrictions. I had content and privacy restrictions enabled, which were blocking Face ID from working properly. Here's how I fixed it:


  1. Go to Settings > Screen Time.
  2. Tap on Content & Privacy Restrictions.
  3. Enter your Screen Time passcode if prompted.
  4. Tap on Passcode Changes and set it to Allow.
  5. After turning off the restriction, Face ID started working again. So, before diving into software or hardware fixes, l'd recommend checking your this settings first.

Actualice el dispositivo, y cuando se reinició el face id no funcionaba, según el soporte decía que había que restablecer el face id, mi sorpresa fue cuando le di restablecer y aparece el mensaje que está activado el modo robo, por ello no puedo restablecerlo y dice que espere 1 hora, para que se desactive la ubicacion segura ya sea de mi casa o la del trabajo, ya paso la hora y sigue bloqueado, entonces tengo el celular de sujeta papeles por que no puedo acceder a nada y necesito acceder a mis datos para poder trabajar.

Bought my brand new IPhone 15 Plus about a week ago, updated it to 18.3.1, once out of the box. Face ID worked fine until a couple of days ago. Haven’t dropped my phone, I take extremely good care of it, almost obsessively. When I picked it up after 2 hours of not using it, Face ID stopped working. I tried everything the internet has to offer, contacted Apple Support and they said that it doesn’t appear to be a hardware issue and that an iOS update MIGHT fix the issue. To me also it’s hard to believe that it may be a hardware issue since the phone is new. I really do hope the next update will fix this. I quote: “It’s not an IPhone without Face ID”
