I was actually a little skeptical because I already had a protective glass of another manufacturer on the display of my S5. However, for I was not satisfied. Scratches during application and constant peel at a corner. Hence my skepticism. However, this glass exceeded all my expectations. Clean screen - Remove protective film from the glass - Put glass on the display and then ....... - wondering about the laws of physics. No pressing or rubbing. By itself, the glass combined with the display, thanks to the adhesive. No bubbles, no nothing. Why not that way.
