Hi there,
It’s probably one of those features who are so expensive it may not even be worth to “genuinely” certify it, but it’s worth of mention that a water-resistant phone would have a MASSIVELY good reception from all those people that for example like to read their ebook on a beach.
The IP68 grade gives you dust and water protections, up until a 1meter.
What do you think about it?
ps: the phone may surely benefit from the fact that it is built with waterproofing in mind, even if the certification is not “paid” and therefore genuine.
