flip cases are pathetic,all of them are very tacky to use,are often made of poor quality materials(non-OEM ones only,not OEM ones),it also doesnt protect the phone much from damage
also its difficult to take photos or even hold the phone properly with a flip case
A capdase,Amzer,TPU silicone case + a scratch guard or tempered glass is much better for any phone than a flip cover and sometimes even cheaper
