Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I am very sorry to have to return both cases we puechased for our Samsung 8 tablets. Due to the strong magnet in the case our tablets do not operate correctly. We even tried taking the keyboard out of the case, but the tablets still got hung up and would not work. The concept is great but will not work with our tablets. We are in the process of returning both cases. Sorry.
