A:AnswerYes it can, but you should RETURN your case until Lifeproof rolls out the new redesign Nuud case. They are all defective with bad charger doors.
A:AnswerThe case doesn't have a screen protector built in but it comes with a removable screen protector. It is also waterproof. Not just under water running from the sink. If you follow the instructions for the underwater test, the testing materials will convincingly demonstrate the cases ability to protect the phone from water. I like having the nuud case because it allows me to interact with the phone as the manufacturer intended touching the actual screen and not a cover.
A:AnswerIf you can forego the waterproof qualities of the LifeProof cases, the most protective one by far is the Otterbox, which can be a little bulky. My last case was an Otterbox slimmer unit. I had to change it as the rubber on the sides starting separating from the hard plastic case. RIght now I'm using a Spec case that's nice.
A:AnswerNot sure if they will. I looked all over for information on it and found none. I went ahead a bough the nuud case and an aftermarket "glass" shield for the screen that fits the screen with the life proof case on.
