A:AnswerIt really depends on the case. I have a Spigen rugged armor but I haven't put mine on yet as I just had my SP installed about 3 hrs ago. I'm going to wait 48 hrs as suggested, however, the young lady at BB that installed mine had this protector on hers with a Spigen liquid crystal case on hers and it looked great! I even took her case off to look at the rounded curves and edges and it was laying flat all around. Color me convinced!
A:AnswerIt is a film that conforms to the shape of the screen. If you plan on using a case, the screen protector must be perfectly centered and given adequate time to "set" before putting on case. I waited 48 hours and it is properly adhering to curved screen and case is not interfering with it.
A:AnswerYes. Call zag. They will send you a replacement screen. The old one peels off easily and leaves no damage. You can also take the phone back to where you bought it and they will put the new screen on for you.
A:Answeryes for a fee. It took the guy a long time to put it on and he had to get a different one because it didn't go on very easily. Glad I had him do it.
A:AnswerYears of experience with various Zagg screen protectors for many different types of devices with good to poor results. This one was excellent for a Samsung Galaxy S8 phone. using a Samsung S-View phone case.
