There is nothing either good or bad but thinking makes it so The mobile phone film can be divided into two categories. One is only for sticking on the screen, the protection of the screen is not damaged. Abother is for sticking the whole body. It will not affect the phone's performance and heat dissipation if it is only for sticking on the screen. Such as my XT800, it is pasted the OK8 frosted screen protective film, it did not affect the performance of the phone and screen sensitivity. Sticking the film for the whole body should consider about the film quality and technology. If it is pasted well, it will not affect the performance of the phone, but the phone itself has small heat dissipation that can be basically ignored. If LZ needs to stick the film, it is recommended to buy ok8 protective film and static film, which is a set of films and the cost performance is high. The advantage of static film is that it can be repeated paste and be cleaned
And according to the professional ophthalmologist, although the brightness of the mobile phone screen itself is enough, the display effect is affected after pasting the film on the screen, and the film itself will also have greater wear after a long-term use which further affect the display effect. They will aggravate the visual fatigue of the users for staring at mobile phone screen in a long time, which will damage the user's vision.
There is a certain protective effect on the cell phone, especially the mobile phone film, but in fact, it is not much necessary. For many people, sticking the film is to prevent the phone screen from scratching, but in fact, such as Apple, the hardness of the screen is relatively high, unless it is deliberately scrached, or it is not easy to be damaged. The hardness of nails is relatively low, it is not possible. the mobile phone film will affect the beauty and brightness of pictures, and it is easy to cause visual fatigue of the user. But the mobile phone price is relatively low, and the hardness of the screen is not great, so you can stick the film. In short, There are both advantages and disadvantages.
