This universal case will fit most mobile phones that have a screen size of 3.5 inch to 4 inch including the iPhone 4. It features an adhesive pad that slides up to allow access to the phone’s camera. Press you phone down onto the adhesive pad & slide it up again to gain access. The case also features an internal credit card slot. Ensure the handset is aligned to the slider before permanently fixing the phone to the case. This case is designed to be used once. To remove & dispose of the case, apply enough pressure to rotate the phone & detach the slider from the case. The slider can then be removed from the phone.
