I've never had this issue before with any iPhones but when I use the 2.5x lens, it never seems to focus properly. I can try taking a pic in the mirror and it doesn't want to focus on me, it'll struggle and be soft. Occasionally it will get in focus but drop out again, I've also noticed it would actually focus on the mirror or window and not the subject past it. I thought it was a hardware issue so I got a replacement from Apple and I am still seeing these results. If I slide my finger over to the 1x just below 2.5x it is immediately much sharper and focused properly even at that slight digital zoom its better. Anyone else having these issues?
