A:AnswerNo it doesn't, you would need to purchase that separately. However, the case protrudes outward just slightly so that if your phone were to fall face down, the screen wouldn't get the brunt of the damage.
A:AnswerUnless the case specifically states that it is compatible with the galaxy A 6 in question - I would say no. I don't believe that OTTERBOX makes a case for the A6. You can visit their website to verify. Did you try searching on best buy's website? When I searched best buy's site I didn't find anything. You can stop by a Best Buy store and have them personally help you. Looks like a good phone that deserves a good case. Best of luck in your search. Cheers!
A:AnswerI haven't tried Samsung Pay yet, but I've had no issues with wireless charging my Galaxy S9+ while using the Pursuit case. I don't imagine Samsung Pay would have an issue.
