How can I fix my disabled Face ID on iPhone after water exposure?

Hello FaceIDgone!

It may be best if you would take your iPhone in for an examination:

• Genius Bar Reservations: Genius Bar Reservation and Apple Support Options
• Locate Apple Stores & AASP’s: Find a Reseller 
• iPhone Service & Repair: iPhone Repair & Service - Apple Support

I hope this is helpful. Good Luck!

Make an appointment at the Apple Store or take the phone to an authorized Apple Service shop.

Authorized locations can be found by opening the link below:

Liquid damage is not repairable. The device will have to be replaced.

"My iPhone was hit with a wave of water on a boat and now my Face ID is disabled. Does anyone know what I need to do to fix it?"

Extract the Water from the iPhone:

Contact your local retailer, asking if they have devices that are made to extract water from mobile devices. Many retailers do.
