A:AnswerI would say you need a rounded case. I purchased 2 of these,one for a iPhone 12 pro max that has a square edge case and it really has trouble staying on. (ESR Sidekick Hybrid Case)
I also purchased the second one for a samsung galaxy s20 ultra. It had a edge case(just covers the edges, RhinoShield Ultra Protective Bumper Case ) and it is rounded. It fits perfectly.
This is my experience and opinion. I hope it helped you
A:AnswerYes, with little to no problem. It has a little give and stretches perfectly to fit the cases. I have it on a Samsung Galaxy Note 10+ which is the same size as yrs.
A:AnswerIf your screen has curved edges it will fit like a glove! If your phone has a straight up sides like a box, then I don’t know, try it on for fit!
A:AnswerHere are the dimensions: Minimum case width: 65.5 mm and max case width: 82.02 mm. Fits most cases including iPhone 12 and 13, 13 Pro, and 13 Pro Max; does not fit phones without a case
