So, I have this case and I like it quite a bit, but I heard from some user reviews on amazon and else where that it might cause signal loss on the phone? I want to make sure I'm getting full reception on my phone, so I'm wondering if anyone has any insights to this. Also, if the case (not the phone) was left in a hot car for a few hours, should it still probably keep its structure and build ok? I'm asking because I took the phone out of the spigen case and left the case in my car while I was out for about 2 hours or so.
