I've used all of the Galaxy S23 fingerprint recognition tempered glass dome glass, EZ glass that is simply attached, and UV GEN film that is hardened. Try the installation yourself and introduce the installation method. We tested whether fingerprint recognition was good after installation, and checked the transparency, touch feeling on the screen, and how it felt when scratched. Each product has its own characteristics and features. Dome glass has the advantage of covering and removing scratches on the screen. It has the advantage of protecting the side end of the curved display. The side part is a little bad, but usually if you use a case together, you can protect this part together. EZ Glass can be easily fitted to simple components. It's so simple that you don't need much explanation. The UV GEN FILM, which is used as a solidification, is too simple to attach, but can be applied with a protective film that is too thin and soft. It has the advantage of protecting the curved display by solidifying with UV while taking advantage of the thin and wearable advantage of PET film.
