Since my phone is almost constantly in use, be annoying smudges and fingerprints can not be avoided on the display. For this reason, I've been looking for and protectors (4 pieces) me at Test.com.de as product testing provider for Samsung Galaxy S5 protective film - crystal clear film Premium Crystal Clear advertised. All in all I have to say that I am very happy with the films. The attaching the protector is easy due to the quake Gege manual and there are no annoying bubbles under the film. But before a star. Furthermore, the films are also well on the display and you see them really well not really. For a second star. Despite the film nevertheless all touchscreen functions are obtained and the price is right. So what you want more? :)
