I have some corrosion issues with my S7. As I understand it has an IP68 rating, and is fully waterproof (i.e. submersion for a reasonable length of time). My job is sometimes messy (and I'm not always the neatest and I'm pretty OCD), so my phone sometimes get dirty. I will rinse it under the tap (max 30 seconds) and occasional uses mild hand soap if something is sticky. Afterwards, I dry it with towels paper and shake/tap it until all the water is out of the ports/jack (a good 30-45 seconds). I'll also usually play a short video to help dry it/clear speakers.
Yet, every time (I've had about 5 S7s, for various reasons) it seems to corrode inside the charging port and jack. I haven't looked with a magnifier, but it at least seems that the metal elements have oxidizes (its green). Why is this happening, since I never leave it wet for more than a minute or two, and it doesn't seem to have rusted? Is there any way to stop this? Some kind of protectant or coatings?
Thanks
