Water in XR front-facing camera

My phone is a few months old and I recently got caught out in the rain with the phone in my pocket. I was soaked, but got the phone out of my wet pocket after about 15 minutes. The next day, I noticed that face ID was no longer working and, upon inspection, I could see tiny water droplets gathered inside of the front-facing camera. I was under the impression that the phone was meant to be waterproof to an extent, let alone water resistant. Does my phone have a defect? Is there anything I can do to fix it? Thanks for the suggestions.
