A:AnswerI bought the otterbox without realizing it had a screen protector in it and also bought the glass screen protector. Couldn’t use the touchscreen on the phone w both so ended up removing the glass screen protector since the screen protector in the otterbox is not removable.
A:AnswerThis says it is for the 7, the 7 plus is larger.
The iPhone 7 is 2.64 inches wide, 5.44 inches tall by 0.28 inches deep and weighs in at 4.87 ounces.
The iPhone 7 Plus is 3.07 inches wide, 6.23 inches tall by 0.29 inches deep and weighs a little more at 6.63 ounces
A:AnswerIt will work over top of the screen protector. Suggest leaving the otterbox screen intact because it helps with the water resistance. Plus, if you alter it like that, you'll void the warranty and lose that valuable benefit.
A:AnswerIf the phone that fits in the case is waterproof then the case is as well. The only problem with that is that you would want to take it apart and get all of the water trapped inside the case out after doing so.
