1.Open the slider and open the front cover from behind the top of the slider. Start from the gap above the sign, insert your nails into the gaps above (if you don't have long nails, wait for the nails to be longer and then dismantle it), and then pry along the gaps to both sides, the action should be slow, (it's okay to be fast, don't blame me if it's broken), this is the most critical process, it may be a little difficult, but how can you see a rainbow without experiencing wind and rain!

Only by going through hardships can we become an opportunity within a machine! 2.After the front cover is removed, you can see our inner screen, remember to be extra cautious when wiping the screen, it is best to wipe it with the glasses cloth that wipes the glasses, and do not use paper supplies, because there are many burrs on the paper, which will wipe the screen.

Let's perfect this feature for Arnold.

4.Tools: a roll of double-sided tape, a sharp knife (don't use a kitchen knife), a discarded CD, a ruler.

5.Tear a piece of double-sided tape and stick it to the disc, don't stick it too tightly, use a ruler and a knife to cut the double-sided tape into long strips with a width of 2mm, and then remove it from the disc, remember to remove the glue! (You may not be able to remove it), and then glue it around the sponge pad of the inner cover.

You have to be very careful with this process, because if it sticks, it may stick to the mat and you will be hopeless (of course you can get a new one). Each side of the surrounding should be glued, after actual testing, it is best to stick two layers of double-sided tape on each side, which will be tighter. 6.

After the above process is done, it is relatively simple post-work, wipe the inner screen of the shell clean, and it's OK. 7.When installing the front cover, start from the bottom of the mobile phone, use the bottom of the front cover to jam the bottom of the slide cover, there are two small card slots under the shell, remember to see clearly, don't install it from above, install the bottom, press down the top of the shell, and you're done.

I am happy to answer for you, and the customer service has found the relevant answer for you 1, transparent tape Yes, you read that right, transparent tape can indeed be used to clean the mobile phone screen, and the effect is very good. Mainly because it can get out a lot of dust that you can't see and garbage hidden in the crevices of the bezel, and it won't damage the phone screen. Of course, remember to use adhesive tape that does not leave residue.

2. Soft cloth + detergent If you feel that the transparent tape is not easy to use, you can try the combination of soft cloth + detergent. The soft cloth does not refer to this kind of cloth on our clothes, but refers to the cloth we buy and give away from the mobile phone film, which will not scratch the screen. Of course, glasses cloth is also possible.

If you don't have a special detergent, you can try to replace it with wind oil essence, and the effect is also good, but you should pay attention to the appropriate amount, otherwise you will have to smell this smell and play with your mobile phone all day long.

Wipe the alcohol pack to clean up the excess gel on it. Kaga.

The mobile phone screen, also known as the display screen, is used to display images and colors. The screen size is calculated according to the diagonal of the screen, usually in inches, which refers to the diagonal length of the screen. With the gradual popularization of mobile phone color screens, the material of mobile phone screens is becoming more and more important.

The color screen of mobile phones varies due to the quality of LCD and R&D technology, and its types are roughly TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the more layers of the picture will be.

According to the material of the screen, the mainstream screens of smartphones can be divided into two categories, one is LCD (abbreviation of Liquid Crystal Display), that is, liquid crystal displays, such as TFT and SLCD screens; The other is OLED (Organic Light-Emitting Diode), that is, organic light-emitting diodes, such as AMOLED series screens. The most fundamental difference between LCD and OLED is that OLED is self-illuminating, while LCD needs to be illuminated by a backlight plate to display.

According to the display technology driving mode of the screen, it can be divided into two categories: passive matrix and active matrix. The difference between passive matrices and active matrices is the way the current is driven. When the external current passes, the arrangement of the liquid crystal will change, and after the current stops, if the liquid crystal arrangement remains in place (with memory), it is called the active moment mu masking; Once the current disappears, it returns to its original position and must be charged again to be arranged, which is called a passive matrix.

Operation method: There are many ways to achieve it, taking Huawei mobile phones as an example, you can contact the after-sales service to disassemble and clean the ash; You can use third-party software to clean the dust, and on some software, the dust of the mobile phone speaker can be expelled by vibration, and you can open and search for such apps.
