I ran into a weird situation where it appeared I was photographing the same bird in every photo I took outdoors and I realized it appeared to be a piece of dust or debris inside the lens of the phone. It was definetely not outside on the lens. I took pains to wipe the phone down with a microfiber cloth and in time it appeared the "bird" vanished but it seems like the phone is taking longer to focus on whatever I'm trying to photograph. I actually will make sure I wipe the lens prior to taking a picture which adds to the time to take a shot anyway now but wondered if anyone else had encountered this? Apple will think I'm crazy but I can't believe how much slower it seems now. I wonder if there is still debris in the lens assembly confusing the camera somehow causing the slowdown.
