Meaning you mean the thing I circled in black is the proximity sensor the dot
Correct, there’s a few dots up there that constitutes of different sensors.
I was using a black Belkin cleaning cloth from a previous screen protector install from iPhone 7 to clean camera lens.
When I was cleaning I notice dust under lens of iPhone X and The phone is three days old under iPhone upgrade program how does apple handle this one ?
Dear lord. Not again.
You have been to the Apple Store with the same problem a dozen times in the past few months.
You know very well how they handle this kind of stuff.
What is the real reason you’re asking it, again, now?
Because mine has two specs from the factory I notice it while clean the back of the phone from my finger prints. The apple store tells me they handle lots of issues like this and even water damage phones.
