Hi i am having issue in the face ID

Hi Maryam6168,

Thanks for coming to Apple Support Communities for help today.

It appears you have seen the correct article. If you are receiving the disabled Face ID alert, your next step is having the iPhone serviced. Please visit Contact Apple Support.

Have a fantastic day

If you're seeing the alert discussed in the article you came here from.. then follow those instructions

If your iOS is up to date and Face ID is still not working, then contact Apple or bring your device in for service
