My stainless steel band oxidizing after a few months use
After using my brand new iPhone 11 Pro for about 6 months, and taking very good care of it with no scratches or any damage at all, I noticed having a blue dot on my stainless steel band next to the charging port. My question is : is this normal for a high end quality phone ? Why ? How can it be fixed ?
Thank you.
