I am not sure I believe this, but I'm sure there are phones that attempted it.

Then read upthread https://news.ycombinator.com/item?id=47835184

I just don't see why we can't have nice things until proven otherwise (especially considering there is already evidence that this works), rather than have glued-shut devices until proven otherwise (by whom then? Apparently IP and practical experiences aren't enough for you)

Samsung only rated the S5 Active as water resistant, and only IP67.

We're talking about IP68, where you can take a new phone with you on a long swim.

I clicked the "parent comment" link all the way to the submission, and opened the submission as well. Nothing mentions IP68. Which "we" is this goalpost coming from?
