Is your Spigen Ultra Hybrid yellowing on the back, or around the edges? (or both?). I believe those 2 parts of the case are made of different materials, is that correct?
I've seen reviews of the entirely clear versions of this case mention yellowing but I’m wondering if the problem is worse in particular on the clear edges/bumper portions. Not super concerned about this for the price, but curious if yellowing is less noticeable with the Ultra Hybrid versions with colored edges, eg like the UH with matte black edges like I ordered.
