Whether frequent replacement of tempered film will wear out the edge of the phone case or screen depends mainly on the operation method and the tools used. If you use your fingernails or hard cards to pry the edge of the film forcibly every time you replace it, it is easy to leave small scratches on the edge of the phone case. Especially for mobile phone frames made of metal, although they are hard, they will gradually lose their original luster and show obvious wear marks when scratched by sharp objects for a long time, affecting the integrity of the appearance.
It is very important to control the force during the film removal process. Some tempered films are tightly attached to the screen. If you use too much force and the direction is not right when removing them, the corners of the film may suddenly bounce up and hit the phone case. Although this instantaneous impact is not strong, it will cause the coating on the edge of the case to gradually fall off and reveal the base color if it happens repeatedly over a long period of time. This damage is more likely to occur on plastic cases. In addition, when pulling the film hard, if a corner of the film is stuck in the gap between the phone case and the screen, a tiny gap may be pried out.
The tools used to clean the screen will also indirectly affect the degree of wear. Before replacing tempered film, it is usually necessary to wipe the screen. If a rough rag or a detergent containing hard particles is used, the particles may rub against the gap between the edge of the screen and the shell during the wiping process, causing burrs on the edge. Especially when there are fine scratches on the edge of the screen, these particles will be embedded in it. Each cleaning may expand the scratch range and make the wear more obvious.
The edge treatment method of tempered film has a certain impact on the risk of wear. The edges of some tempered films are not cut smoothly, and there are burrs or sharp angles. If they come into contact with the edge of the mobile phone shell many times during replacement, they will repeatedly rub the shell like sandpaper, causing chronic wear. In addition, some tempered films do not match the size of the mobile phone, and the edges exceed the screen range. When removing the film, these extra edges are more likely to hook the shell, aggravating wear.
The alignment process when installing a new film may also cause wear. If the position of the film is adjusted many times, the edge of the film will slide repeatedly on the mobile phone shell. Especially when there is dust on the film, the dust particles will be sandwiched between the film and the shell. The sliding process is equivalent to grinding the surface of the shell, resulting in fine scratches. For curved screen phones, you need to press the edge to make it fit when applying the film. Repeated pressing may cause the edge of the shell to deform due to stress, which may indirectly cause damage.
The material of the phone shell itself determines its wear resistance. The back shell made of glass or ceramic material is relatively hard, and frequent replacement of tempered film usually does not cause obvious wear; while the frosted or glossy plastic back shell has poor wear resistance, and it is easy to turn white or scratch after repeated contact with the edge of the film application tool or the film. If the rubber ring on the edge of the screen is made of rubber, it may be deformed or aged due to long-term compression and friction by the edge of the film, affecting the sealing performance.
The correct operation method can greatly reduce the risk of wear. When replacing, use a special film prying tool, gently lift up from one corner of the film, and avoid contact with the shell; when cleaning the screen, use a soft microfiber cloth with a special cleaning agent to reduce particle friction; choose a tempered film with precise size and smooth edges, and accurately align it once during installation to reduce the number of adjustments. As long as the operation is proper, even if the tempered film is frequently replaced, it can effectively avoid obvious wear on the phone shell and screen edge.
