Bests & Worsts Reviews from Amazon

I bought this clear -back case for a new iPhone 12. It fits very well and seems to be very protective. Spiegen products are always well made and do wha that they say they will. The only issue I have is that in the center of the clear screen on the phone back, a spot keeps appearing where the clear case back appears to be in contact with the back surface of the phone and it appears the plastic and back are “sticking” together in a small oval-shaped dot. I’ve cleaned both the case and the back of my phone several time but this keeps re-appearing. It does no damage but doesn’t look good. Don’t know if there’s a defect in clear part of case or this is a common issue. Like the case otherwise.
