A:AnswerIf your not sure if its still working, test it without your phone in it. Take your phone out using a quarter to pry it open where.the indented slots are. Push it back together and test it in a sink full of water. Place something heavy on it so its fully immersed. then open it again and see if any water got in.
When you put your phone back in make sure it clicks down all the way.
A:AnswerYes it will fit in the case the screen protectors are not thick and they do add the extra protection from scratches!!! Plus if you had it out of the case and accidently drop it, the (glass protectors) will add that cushion so the screen won't crack.
A:AnswerYes!! I originally switched back to an otterbox only due to the earphone attachment on the Lifeproof but after having to remove the cover repeatedly to dry off my phone, I went right back to the Lifeproof.
