The major reason I bought the S5 is that it is waterproof. Being an industrial concrete specialist, sometimes I have to scurry to do things in a downpour. For an added layer of security, I purchased an Otterbox Defender case. I've had my phone for a while now, and the phone itself has not one blemish! I am looking into wireless charging, because I worry about the USB cover breaking. Some people say use this Qi receiver, some people say to buy a wireless charging cover. Bottom line is, I cannot afford to let my phone lose it's IP67 rating. And, I'm the type I don't want scratches on the screen or shell. I regularly disassemble the case to remove dust from both the phone and case. Does anyone have any real-world advice?
