Iphone 5S earphone jack brown corrosion - No apple store in 1500 miles radios
My Iphone is in use for less than 2 months, and its earphone jack is getting brown in its bottom. Is it normal? Seems to be corrosion.
iPhone 5s, iOS 7.0.4
Has it been exposed to moisture such as steam in the bathroom, extreme cold, etc?
Take a good flashlight and magnifying glass and explore further. It may be just dirt/debris and you can clean it.
