can i replace faceid dot project in iphone x

When a liquid damage occurs, the only way to understand the severity of the damage is to thoroughly inspect the device, which we cannot do remotely.

Unfortunately, there are often corrosion effects to internal components that occur later, making the intervention you intend to do insufficient. That said, we have no certainty that this repair can be decisive.

I recommend having your iPhone inspected at an Apple Store or AASP. After checking, they will be able to offer you all the options available.

Water damaged devices are not repairable and it must be replaced.

Water damage is not covered by the standard warranty so the replacement costs are your expense.
