I recently picked up a black Apple leather case for my iPhone 6, and while I really like the fit, the feel, and the slim profile, there's a big problem with this case. It keeps forming these 'blisters'. Spots on the surface raise up in these 'bubbles' that just don't look very good. I noticed that this happens if I lay the phone down on any moisture. I don't mean that I'm getting it really wet or anything, rather, if I have a glass on the table and then I put the case down where the glass had been sitting, the little bit of condensation from the glass seems to get absorbed into the leather and form these permanent 'blisters'. I don't know if the leather is expanding or if the outer layer is separating from the inner, but either way, this is unacceptable. The Apple leather case for my 5S never did anything like this. I've had the case for only 5 days, and it already looks like this and is getting worse: So my question is, did I get a faulty case or are all of them defective like this? Should I simply try to exchange it for another one, or should I swap it for the Apple silicone case?
