I have the bodyguardz (BG) screenprotector for the iphone 5 with a bumper. But they seem not compatible. I think this is cause because the BG screenprotector is too thin. Too edges will move while the bumper is attachment. Which will cause space between the screenprotector and the screen. Which will result in getting dust under the screenprotector. After a month i need to remove the screenprotector because it's all messed up. Do i need a thicker screenprotectors? any experience with a bumper and a screenprotector? brand that can be recommended?
