Second hole on top

[Adi0]

For anyone that is confused and thinks that the second hole on top is a second microphone, no it's a hole to test water resistance and help with the pressure inside phone. I've literally asked that the Samsung employee when I was in a Samsung Korea factory. S23, Flip/Fold 5 too.

Literally looking up the 2 holes ... This was the first result.

Well done, and thanks.

Fyi in the user guide, it just says, air hole.

No, I've literally asked the factory manager in Korea last summer. I wish Samsung stated that clearly. Everybody things that it's a second mic which makes no sense.

I inserted the SIM ejector in the air hole, could it spoil the phone's water resistance??

[Adi0]

No, it's not possible.

It's for a lanyard.

When you buy a UAG case they show that they have open space left for these two holes as it is meant for lanyard.

Rubbish, in a boat you need a second hole to let the water back out...! Same on this ..lol

That's the one on the case usually bottom left or right on the side
