Set of 3 protective films for Samsung Galaxy S4. The film effectively protects the phone's display from scratches and smudges. Even the smallest scratch or a simple mishap can result in your phone's screen never being the same again, and in the worst case, you may have to replace it. Therefore, it is worth equipping it with an additional layer of protection in the form of a special display film, so you can always see what you want on it. The film does not affect the sensitivity of the touchscreen.
