My iPhone no face id apply

Welcome quocphuong,

We understand you have issues with Face ID being disabled on your iPhone XS Max. We'll do our best to help out with this.

You came from the best resource for your issue with Face ID being disabled: If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support As mentioned there, you'll want to take these steps to solve it:

What to do next

1. Update your iPhone or iPad to the latest version of iOS or iPadOS.

2. Check if there is an issue with Face ID in your iPhone's parts and service history. To do this, open the Settings app, tap General, then tap About.

3. If you still can't enroll your face or unlock your device with Face ID, you can take your device to an Apple Store or Apple Authorized Service Provider, or contact Apple Support about your iPhone or your iPad.

Only a trained technician should service your device. Improper repair, modification, or use of nongenuine Apple components in the laser systems might prevent the safety mechanisms from functioning properly and could cause hazardous exposure and injury to eyes or skin.

What the message means

Using diagnostics available in iOS 14.6 or later, Apple has detected an issue with your TrueDepth camera that might cause it to not function as expected. The TrueDepth camera contains lasers, which might be disabled for safety reasons if the device malfunctions or is damaged. This won't prevent you from using your iPhone or iPad, but until your iPhone or iPad is updated or serviced, you might not be able to use Face ID, Animoji, Memoji, and some other features that use the front camera.

If you've already updated the iPhone, then you'll want to seek an inspection due to the hardware issue mentioned above: iPhone Repair and Service
