The Xiaomi Mi 6 is splash resistant, but what gives it that resistance? And why isnít it rated for full water resistance? The best way to find that out is to take the phone apart. And while he was at it, JerryRigEverything also stripped the back glass of paint to show off the internals of the phone.
It seems that Xiaomi got 90% of the way there to waterproofing the Mi 6. The SIM slot has a rubber seal, thereís no headphone jack and every speaker and mic grille have special mesh screens that keep water out. The one hole thatís left wide open is the USB-C port - thereís no waterproofing on it at all. Perhaps Xiaomi can finish the job for the Mi 6 Plus?
As for disassembling the rest of the phone, itís all standard Philips head screws and some sticky tape - there are no major roadblocks to taking the Mi 6 apart. Here, watch a pro do it:
Nice Video. Zack is right, adding new features is infinitely better than removing features. So all manufacturers, please don't remove the 3.5 mm headphone jack in your next smartphones. (I'm looking at you Xiaomi, HTC, Motorola & Apple).
Good Xiaomi. And so hopefully and probably for the next one (Mi 6 Plus).
Any Android phone will have the contacts on Google, so when the phone dies, the contacts list is not affected. It is on by default, unless you choose not to do that, which is your own fault.
