Mobile phones are now an indispensable part in our daily life. The current mobile phone is not just for making calls. More and more important functions of mobile phones may be shopping, chatting, taking pictures and other important tools. In today's society If we don't have mobile phones, we may not be able to carry out a single step in our daily life. The damage of the mobile phone screen is a thing that troubles many friends. Now I will introduce to my friends how to replace the mobile phone screen. The screen structure of a mobile phone is generally divided into three parts: the outer screen, the touch screen and the inner screen. We need to identify the degree of screen damage. The display is normal (external screen is damaged), the display is not working (internal screen is damaged), whether it is internal or external screen damage will eventually cause damage to the internal screen, so the screen needs to be replaced. The phone is suddenly broken and the screen cannot be seen clearly. There is a high probability that the screen needs to be replaced, because there are still a lot of data, pictures, and information that need to be exported. At least the phone needs to work normally for a period of time. We need to have a mobile phone screen before we can replace it. At this time, we need to purchase the corresponding model of mobile phone screen and some maintenance tools such as screwdrivers and suction cups. The screen of the mobile phone we bought comes with a film itself, and a small label is pasted on the side. It is recommended to turn on the phone and test whether the new screen is easy to use and whether there are any defects before installing the back cover. Do not tear off the film first, in case there is a problem with the screen, it is convenient to return it to the merchant. Before replacing, we must carefully read the precautions for using the tool. We need to do it step by step, so even if you don’t have experience, don’t worry. There are many small screws on the back of the phone. They are all small screws, and there are also differences in size. When you put it back, you can't make a mistake. We need to remove the back cover, open the back cover, and the rest is to remove the main board, battery, touch screen, etc., and move all the gadgets on the original mobile phone to the new mobile phone case. Just install the motherboard, camera, battery, etc. in order. Once the battery is installed and before you start installing the rear cover, it's time to test the screen. In most cases, there is no problem with the screen, and the display, touch and other operations are normal, but you should test it first, which is also a necessary process for installing the screen. In the screen testing, after various operations, if no abnormalities are found, the rear cover can be closed. When people hear the thing that changing the screen of a mobile phone or taking apart a mobile phone, they will feel that it is very troublesome and difficult, and may damage the mobile phone, but this is not the case. If the screen is broken needs to be replaced, or the battery of the mobile phone is old, if you want to replace the battery, then try it yourself. The current mobile phone is just like a desktop computer. It is made of superimposed parts one by one, modular, If something is broken, just replace the corresponding components.
