I only tried applying a screen protector myself once and it wasn't the great. I wound up removing it. Years ago, when I got my iPhone X at the Apple Store I decided to go without. But I saw that they had a machine to apply screen protectors to other people's phones. That might do it better than you or I.Tried the ESR Tempered Glass Screen Protector, and while the fit and feel was excellent—I could NOT get it on without getting dust trapped underneath, which bugged me endlessly. Might take it down to the mall and get one of the guys at the kiosk to apply it, but I doubt he’d do much better of a job than I. Ugh I really wouldn’t mind a good screen protector but I can’t deal with the tiny dust specs that become visible when looking at white screens.
