About splash, water, and dust resistance of iPhone 7 and later - Apple Support
“The iPhone 7 and later is splash, water, and dust resistant and was tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions, and resistance might decrease as a result of normal wear. Liquid damage is not covered under warranty.”
That is different from waterproof.
Is it that you brought it in for service, and they detected water damage on the inside?
