So the iPhone X has IP67 rating, but my iPhone X doesn't seem to live up to that standard -- this morning, some dasani water was accidentally spilled on to my iphone, maybe 1/4 of the bottle, and the earpiece sounds 'muddy' now when playing music or making phone calls. I do have AppleCare+, would this cover it? I heard that depiste the IP67 rating, that water damage is not covered under the warranty.
