iPhone 12 iPhone 12 - FaceID - TrueDepth

[Konstantinos21]

Hi! I have iPhone 12 with FaceID enabled. I noticed that the TrueDepth camera works all the time. If I place the mobile phone in front of another camera, the infrared light is constantly visible. Can I stop it? I want it to work only when needed, eg when unlocking. Thanks in advance!

Guessing now but maybe its related to the "turn attention aware" feature?

GIve it a try and turn it off and see what happens.

Not sure if this is part of how it’s all supposed to work By default Is this something you noticed recently or in relation to repair works or a software update?
What OS version are u on?

I suspect there might be a few more features that might use it, have you tried turning off “raise to wake”?

I bought the iPhone recently. It was used for a year. So I don't know if something happened inside it. It runs iOS 17.5.1. The "rase to wake" feature is disabled.

Ok. What if you, just as a test, turn off Face ID completely?

Exactly the same problem

Sounds like it’s just always on then ¯\_(ツ)_/¯ I don’t have an iPhone 12 to check.

From what I can gather, since you turned off the attention aware features it could just be the proximity sensor, which on iPhones with the larger notch it was put in between the Flood Illuminator and Dot Matrix Projector, parts of the TrueDepth Camera and you can't turn it off.
