To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Both screen protectors came with crap on the back before I pulled off the protective plastic to put on my phone. The first had so much junk on it I just pulled it off and pitched it thinking I had a 2nd, the 2nd was slightly better but cracked the first time I put it in my pocket.
