That's water and dust resistance, not air
dude what lol
Wdym? Water has surface tension and dust is solid, air doesn't have such limitations. My own phone (note 20 ultra) has an opening under the camera bump to allow air in to relive pressure despite having an ip68 rating.
Are you sure that's not a microphone for videos? It'd be really weird to have a hole like that. Water should easily push itself through that hole. I honestly don't know what you're talking about when it comes to air pressure. I'm pretty sure your eardrums can survive close to a 1 atmosphere difference in pressure, and those are way more fragile than your phone. I'm not sure why your phone would need to normalize air pressure.
Ever pop your ears when going up a mountain or during flight? This is air pressure changes. Either way, water tight does not mean air tight, while air tight does mean water tight assuming the material is not water soluble.
Now that I think about it it is a third microphone. When they came out there were many posts of S20Us' and note20Us' camera glasses spontaneously shattering and the consensus from what I read was sudden pressure change. The same thing happened to my previous phone while in my locker (galaxy c9 pro with a single small camera and no hole), so it sounded plausible. And it's also believable that water doesn't go in from surface tension alone since the hole is really small
Regardless I forgot that that it was supposed to be a microphone while posting my comments so nevermind
Edit: also phones do normalise air pressure, just get a barometer app and squeeze the phone
