IP67 in reality won’t last 30 minutes submerged in most cases. I’ve had flagship level IP67 devices get damaged by water ingress by being splashed or dunked a couple inches into a pool for less than a second. My Pixel 8 Pro goes into the shower, bath, pool, hot tub, and rain with me and it’s never skipped a beat.
