IPhone 10 water resistant?

I was given a replacement iPhone X from Apple less than 3 months ago for a warranty relating to failures with the screen with overheating, facial ID and bad keyboard texting... My new replacement phone gets wet while taking pictures outside

but the water sensor are not triggered. A few hours later the phone stops working. Apple says there is nothing they can do to save the phone since it wouldn’t power up. All that came up was Apple symbol so I knew phone wasn't completely dead. A local repair shop restores the phone and it now works. However it still has issues. Facial ID no longer works again.. Apple says any warranty is now void due to water damage and for my using an independent third-party for repairing the phone. They say they “lost some screws” and due that and the signs of water corrosion they have devalued the phone to nothing! I have received conflicting stories from Apple representatives on this.. The manager addressed things by offering me a replacement phone for $549, not good enough! When my phone was replaced 3 months ago tech support says “ Apple can afford this” To clarify, this phone was never submerged and only had condensation visible around camera lens. I’m struggling to understand why Apple advertises water resistant but does not replace this phone when it fails. Any feedback is appreciated good or bad. Just trying to make sense of it..
