Recently, many users have reported in the Apple community that Face ID cannot be used after the iPhone is upgraded to iOS 16. When trying to reset Face ID, the system will pop up a window prompting "Face ID is not available, try to set up Face ID later."
If this pop-up window appears on your iPhone without dropping the phone or the phone has been flooded, the possibility of system software errors is relatively high. You can refer to the following methods to solve it:
1. Try restarting your iPhone
Temporary bugs may occur when the iPhone system is in use. At this time, you only need to restart the device to return to normal.
Restart method: Press and hold the side button and any volume key at the same time until the shutdown slider appears, then slide the slider to shut down; then press and hold the side button until the Apple logo appears. (Applicable to iPhone X and newer models)
2. Update the system to the latest version
Apple will release iOS updates from time to time to fix various bugs that appear on iPhone devices.
You can try to upgrade your phone's system to the latest version. Go to [Settings] - [General] - [Software Update] to check the latest iOS version.
3. Remove iPhone protective film
If the face ID is not available, it is also possible that the iPhone uses a tempered film that is too thick and has poor light transmittance, which will affect the light sensor, distance sensor and even the face sensor. At this time, you can try to peel off the film and wipe the face sensor.
4. Try to restore factory settings
If the fault persists, you can try to restore the factory settings, and it is recommended to back up important files in advance (it is recommended to use iTunes to enter the whole machine backup)!
How to restore factory settings: Go to [Settings] - [General] - [Transfer or Restore iPhone] - [Erase All Content and Settings], and follow the system instructions to restore iPhone to factory settings.
5. Use iOS system repair tool
If you don't want to erase the data on your iPhone, you can try to use a professional third-party tool to get into the repair.
Funke iOS System Repair Tool supports repairing more than 150 iOS system problems, and the standard mode will not erase the data on the device. This tool is very easy to operate, Xiaobai can easily repair iPhone at home!
If you still cannot solve the problem after trying all the above methods, it is recommended to go to the nearest Apple official after-sales or authorized repair service provider for further inspection or repair.
If your iPhone is within the warranty period and the Face ID is damaged due to non-human reasons, Apple officials will repair it for you free of charge.
