Face ID failure after water damage

I have an iPhone XR 64GB, and it was dunked in about 4 inches of water for about a minute about 3 months ago. Around 30 minutes after the dunking, the rear camera and Face ID stopped working. The rear camera started working again, but Face ID has not started working since, displaying the message "A problem was detected with the truedepth camera. Face ID has been disabled."

Is there anything I can do to fix this problem? Maybe removing the front camera assembly on the housing? I have removed the front earspeaker assembly that is connected to the display for about 2 weeks to dry, but Face ID still currently doesn't work. I am aware that the sensor is paired to the logic board and therefore it is impossible to replace. Unfortunately, I am also aware that apple will not fix the iPhone if the LCI indicators have turned red, which is unfortunately the case. Is there anything else I can do to this iPhone or is it done for? All other functions work on the iPhone.

I would also like to mention that the iPhone was in no way taken apart or tampered with before the dunking. There were also no visible cracks and was in pristine condition, so it was water resistant.

Hi @wen90804

Check if the LDI has changed colour. If it has then water has penetrated the phone.

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away. However, after the amount of time since it happened you can only try to clean it and check if that fixes the problem..

First do not try to charge or to turn on your phone and then remove the battery as soon as possible from the phone to minimize any further damage. Corrosion can still conduct electricity if it is humid enough

Dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that describes the process. Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water (and subsequent corrosion) may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well

Hopefully after you have done all this the phone might possibly work correctly again.

Here is the ifixit iPhone XR guide that may help

If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair.

Done for I'm afraid unless you can find a micro soldering shop that can disassemble the face id components, remove the corrosion and solder it all back together.
