New flagship smartphones Samsung and Apple are protected from water and dust. But only the iPhone 7 and iPhone 7 Plus received certification according to the IP67 standard, and the Galaxy S8 and Galaxy S8 + – according to IP68. Whether the devices of different degrees of protection will help to withstand the flour of cold equally while staying in the freezer at -35 ° C and testing in water can be seen in the following videos. The test results were mixed. Only the freezer Samsung and Apple survived equally well. In water tests, the iPhone 7 Plus, then the Galaxy S8 + became an outsider. Apparently it all comes down to the case. Unambiguously, we can only say that the accidental ingress into the aquatic environment of all flagship smartphones will endure painlessly. At the same time, I would like to see how top-end mobile phones withstand sea water and a hot shower / bath. Although, if you take into account the advertising clip of the telecommunication company T-Mobile, there are no reasons for the South Korean flags to experience sea depths.
