I use the 3.5mm audio jack daily, anywhere from 1 hour to 9 hours a day.
How often is my phone exposed to being submersed in water? 0 hours daily. Even if I use it outside, I have a thing called a rain jacket which has a pocket where the phone resides in.
Amount of times I've needed a waterproof phone? 0.
So I guess I'm just not the target market for the Pixel or the new iPhones. Oh well! I'll just carry on as best I can not paying big money for a phone.
