Case always open - there is no magnet, plastic holder has a very bad fit.
Very good quality with sewing border. When you'll close, the screen of Samsung Galaxy S4 change to fit on opening Windows. But ... I try to put my Samsung S4 on the support and I cannot manage. So I cannot use it ... I think the reason is that My S4 Samsung has a NFC power charge kit on the back and the back is a bit thicker. My Samsung S4 is 1cm thick with NFC power charge kit. If your S4 Samsung has a NFC charge power kit on the back, DON'T BUY IT. On the description of the product, customers cannot see the detail of the support. I'm disappointed. The support has a rigid plastic and cannot expand if the back is a bit thicker. The best issue to improve this product is having a silicon plastic instead of a rigid plastic on the back to fit on.
