Not long after dropping my own Mi 10T Pro in deep snow and fearing that might have led to water ingress, I discovered a series of tests that prove how resilient it is. Although not advertised as waterproof, it looks like the Xiaomi Mi 10T Pro can even handle short immersions in shallow water alongside the usual splashes.

I'm still annoyed with the glass back of my S6 Edge shattering into a zillion pieces held together by the case glue. Made me join the Plastic Backs Advocacy Group® for a while.
No issues with my Xiaomi mid-ranger with a good glass back, even as I ritualistically drop it every couple of months.
So the cheaper Xiaomi apparently uses better glass or has a better build than the Samsungs... very interesting!
