I use the Caseology Envoy case. It will fit tightly but works well. I did need to use a dremel tool and grind a little bit around the charging port area so I could plug it in when I needed to. Also the Samsung Galaxy Note 4 N9100 Border Bumper Case, Slim Armor Border Shockproof Bumper Frame Case Cover will fit as well. I use both alternately. Both cases can be bought on Amazon. Hope this helps, I had a devil of a time finding cases that fit!
