Many people carry a mobile phone in their pocket or purse without a special case. With this operation, the appearance of the device quickly deteriorates. The inscriptions on the buttons are erased, and the display shows ugly scratches from the stylus, keys and other contents of pockets or bags. From such troubles, the phone
Keeps a protective film.
This very useful accessory is of two types: disposable and reusable. Reusable films are usually made of thick plastic sheets. Such a film is glued onto the phone screen easily, and to update the appearance of the device, just remove it and wash it. Reusable protective film for the phone has antistatic properties and has a structural matte surface. That is, the display under the film is protected from dust, and glare will not interfere with using the phone even in the sun. The only drawback of the anti-glare function is a slight decrease in screen contrast. Since the film is quite thick, the stylus will also have to be pressed harder.
Recently, several more varieties of reusable film have appeared. For example, Ultra Clear protective film transmits 99 percent of the light, but does not save from sun glare . Another type of film, mirror-like, looks very impressive, but the color rendering of mirror films is still
worse than matte ones, and you have to wipe them much more often.
Disposable protective film has a glossy surface. It is not easy to stick such a film without “bubbles” and dust particles falling under it, and it is even more difficult to remove it. The advantage of such protection is the small density of the accessory, which does not reduce the sensitivity and contrast of the touch screen. It costs one-time protection no more than two dollars. There are cheaper films made in China, but they last only a couple of months, while high-quality film can be used for about a year.
On the phone, the protective film is glued in several stages. First, thoroughly clean the display of dust. To do this, you can use napkins or sprays for the monitor. Then grasp the “petal" and separate the film from the transport base, attach one side of it to the long edge of the screen and
gently press - the elastic film will immediately stick. If it sticks unevenly, do not be afraid to tear it off and repeat the procedure. Air bubbles that accidentally form under the film can be removed by swiping the display with a solid object, such as a plastic card. The bubbles remaining after this mean that the film is of poor quality and will not be enough for a long time.
It’s very easy to take care of a film-coated display; sometimes it’s enough to clean it with plain water. The accessory itself can also be rinsed with clean water - if the film is of high quality, it will not hurt it. In this way, dust particles adhering to the adhesive side can be removed. However, do not do this too often, otherwise the film will stop sticking.
Each useful handy accessory, such as a protective film. For iPhone 4, it is especially useful, because such an elite smartphone should be protected from any damage immediately after purchase.
