Was concerned that the phone was held in place by adhesion only, so degreased my daughters phone with methylated spirit so as to get a good key to back of phone.
After 10 days my daughter was complaining that when the case gets warm in your pocket, the phone slips out of place as the glue on the pad has softened.
This week she told me the securing pin on the side had now broken due to the phone moving freely around. She had the case less than a month and is now useless. A bad buy.
