On my iPhone X’s max the back panel there a tiny dot that’s look like glue I even circled it. What can it be and it’s not affecting the performance of the phone FYI I don’t use wireless charging at all and the back panel looks sealed to me ? A).I don’t want to go to apple for this tiny issue and get looked wrong. B). I don’t want to replace the phone I learned this year replacing products for a replacement aren’t the same as the orginal one that’s came from the factory. C).I don’t really want to go to the replacements route never again since the phone is only with me 12 months if it’s really bad I will take action. D).I ordered a different case so I can hide the blemish. What would you people recommend I do for now instead of me going to apple for the small issue that’s not even a big issue yet ?
