A:Answeryes it will and to further note the wireless charging will work with any case as long is there is no metal in the back of them where they set over the wireless charge. i had on the s4 s6 and s7 all tested in otter boxes only time any of them wouldnt work is if a case had metal.
A:AnswerI don't know. Usually the cases are designed specifically for the phone and size. Seems like each model changes sizes and location of the plug ins
A:AnswerIf you buy the OtterBox Defender it comes with a belt clip with it. If you already have the OtterBox and just need the belt clip then I would first check with Best Buy to see if you can buy one with them. If you can't then you can always get one online at OtterBox's website.
