How can water get into my iPhone 7+?

I’m not saying the OP was reckless nor careless, but just that the caveat to an IP67 rated device that water damage voids warranty is not at all unique to Apple. Samsung, LG and others have also refused warranty on their IP67 devices when the damage was caused by water.

Samsung had a commercial where a guy is completely freaking out that he's going to damage his phone and he's literally booting it around (keeping it off the ground) for 30 seconds until (I think) it finally lands in muddy puddle of grass. There is a Samsung commercial from outside the US showing a guy answering his phone in the shower or accidentally knocking it in a sink full of water. I would think that would run into "implied warranty of merchantability" that those are intended uses. At least I haven't seen an Apple commercial showing that.

I totally get that Apple is only saying "We'll try our best, but no guarantees" with regards to water resistance.

Samsung also had one (cannot remember the model) with people swimming in a pool with it taking pics under water. They later pulled that commercial and ended up refusing to honor warranties on the device if used when swimming after a flood (pun intended) of claims of damaged phones. Turned out it really wasn’t suitable as an underwater camera!

Sometimes I think the marketing and ad guys just forget to talk to the actual engineers before going to air 😁

That is the problem. How can you prove that to Apple?

I was going to ask if anyone was with you but that would soon get into that circular claim of 'you say, they say'.

I can only report that in my experience Apple have always shown willing and while that is not your experience here, I cannot see a resolution other than reconsideration and good will from Apple.

Apple do everything 'in theory'. In practice, immersion in water is a bad thing, as time spent in this forum will attest.
