I have been treating all my past iPhones with great respect, and this one is no different. Sadly I have recently noticed that a pretty visible black dot is present in lower left corner of each picture I take with my phone. Strangely videos shot with iP don't have that problem. Is that dust? How did it get there and how do I get rid of it? Thank you.
