What is the definition of water damaged?
My iPhone X got wet, the camera is blur and face id stopped working. Didn't know if the quality of the phones are not equally the same, while mine has problem but others which I observed they put the phone into water but still works perfectly fine. The thing is when I read this article: Liquid damage to iPhone or iPod isn't covered by warranty - Apple Support, I couldn't find the red indicator as described, which I think it's not being water damaged and thus eligible for warranty.
However, Apple Authorized Service in Vietnam are really unprofessional. They don't know what LCI is, just looked at the phone and rejected the warranty. Not only that, I chat with an Apple advisor, he suggested me to come to VStore, which turned out to be a Reseller and don't have functions to repair or check hardware issue. It's very unprofessional for Apple to point me to a place that redirected me to another place then, such a waste of time.
Now my phone is still unrepaired, authorized services here insist that the phone is water damaged without checking the LCI, could someone please confirm if the LCI is the valid check for water damaged condition? This issue also raised a concern about build quality of Apple's products.
