1. Methods for repairing mobile phone screens



1. Replace the outer screen (press screen) using equipment



Screen pressing is a common method for repairing broken mobile phone screens, primarily targeting repairs to the outer glass layer of the screen. Since it involves repairing the outer screen, the inner screen of your phone must be intact before this method can be applied. Screen pressing involves reattaching the new outer glass layer and display layer together, and then using professional equipment to press them together, ensuring they are tightly combined. The advantage of this method is that the repair cost is relatively low, and once repaired, it will not affect other functions of the phone.




However, it should be noted that screen pressing requires professional equipment and technology, which cannot be operated by ordinary repair shops, and it is also impossible to press the screen by oneself.





2. Replace the entire screen



If our phone screen is severely damaged and the internal screen is already damaged (screen display is abnormal, screen leakage, lines, black screen), then we need to consider replacing the screen.



Screen replacement is the process of removing the entire screen and replacing it with a new one. The advantage of this method is that it can completely solve the problem, but the price of the original screen is relatively high, and reliable repairers need to be found to ensure the quality of the screen.



2、 The price for changing the screen

The price of screen replacement varies depending on the brand, model, and repair method. Generally speaking, if only the external screen is damaged, we only need to find a professional repair shop to replace the external screen.
We are a professional wholesale company for various mobile phone screens and accessories, with over 10 years of one-stop procurement services for mobile phone accessories. We offer affordable prices, reliable quality, and guaranteed after-sales service. Please feel free to contact us！





If the internal screen is damaged, replacing the original screen may be more expensive. If you have high requirements, you can directly replace it with an original screen assembly. If the requirements are not very high, you can replace it with a brand screen assembly. If it is only a spare machine or just wants to export data, you can directly replace it with an assembled screen.





In addition, it is recommended to choose to have your phone screen repaired in store or by mail. Some home repair and screen replacement services often use an assembled screen to replace your original screen, especially if your phone only has a broken external screen. When replacing a phone screen, don't just look at the price. The price of replacing the external screen is closely related to the repair techniques of the technician. Some cheap repair shops have many tricks for replacing the external screen, such as not bearing the risk of the internal screen, which will ultimately lead to the price of repairing the screen increasing several times. The same goes for replacing the screen assembly. There are assembled screens, branded screens, press fit screens, face change screens, original disassembled screens, original touch screen replacement, screen replacement, and so on in the market. Anyway, remember that you get what you pay for. When repairing a screen, try to go to a store that only does repairs. For those who are not familiar with screens, please contact me. We can provide wholesale and after-sales services for various screens。Tina WhatsApp:+86 13824303378





In summary, if your phone screen is damaged and only the external screen is broken, we only need to replace the external screen. If the internal screen is damaged, we need to replace the entire screen assembly. We can choose the appropriate repair method according to our own situation. At the same time, when choosing a repair shop, it is necessary to choose a reliable merchant to ensure the quality and effectiveness of the repair.

1、 External reasons


① Charger data cable


When charging with a non original charger data cable, the voltage is unstable, which can cause the screen to malfunction and jump. It is recommended to disconnect and replace the charger data cable.



② Screen protector film


Poor quality tempered film may affect the touch effect. It is recommended to tear off the film and check if the sensitivity is restored.



③ Water or dirt on hands



You can try wiping the screen of your phone with a tissue to remove any oil stains that may cause touch drift.



④ There is static electricity present


Static electricity on mobile phones can also be uncontrollable. In this case, you can lock the screen and charge the phone for ten minutes to solve the problem.



2、 System reasons


① Software issues


Determine whether it is a certain software or all software fixed area touch failure. If a single software is not sensitive in that area, it may be due to software issues. If all software has the same location touch failure, it is a screen problem and needs to be repaired.



② Too many backend software


Opening the software in the background is likely to cause the mobile phone to get too laggy, and the screen is not sensitive. Try to close the background running software.



③ System issues


If there are many applications installed on the mobile system and the phone configuration is not high, it is easy to cause insufficient phone resources, so this phenomenon may also occur. It is recommended that you try to restore the factory settings or flash the phone.



④ Crash or false crash


It can be resolved by turning off the screen or restarting the phone.



3、 Screen related reasons


Touch failure caused by the screen itself: such as dropping the phone, loosening the LCD screen cable after liquid ingress, and corrosion of the touch IC. These hardware damages can cause the screen to drift and touch failure.



How about it, have you learned how to judge?



It should be noted that the hardware failure of the screen itself involves the repair of internal parts of the phone, which cannot be repaired by an individual. It is necessary to seek professional maintenance personnel for repair and replacement. Do not disassemble or repair it yourself to avoid losses.

Don't panic, the first step in self-study is to "line out" the screen

'Screen out' often means that the internal screen is damaged, so it's better to do it yourself instead of wasting money. Taking S15Pro as an example, the entire screen replacement process is broken down into 7 key nodes, each step accompanied by real-life photos, and following along can save a lot of maintenance costs.

02
Removing the back cover: The glass material needs to be 'translated'

2.1 ◇ First, cut open the double-sided tape, and then lift the cover in parallel
Lightly scratch along the border with a thin card, loosen the double-sided tape completely, and then move it as a whole. Avoid breaking it hard at 90 °, otherwise the back cover will instantly break into a "puzzle".



2.2 ◇ Remove the protective cover and battery
After removing the back cover, unscrew all the fixing screws around the body without missing a single screw; After removing the protective cover, disconnect the battery and power off the motherboard to avoid short circuits during installation.

03
Take the small board: first disconnect the cable and then take the screw

3.1 ◇ Loosen the display cable and charging port
Gently loosen the speaker and display cable interface, and there is also a straight screw on the top of the small board. After removing it, all cables can be pulled out.

3.2 ◇ Remove the card tray and protect the red dust-proof adhesive
Use tweezers to grip the card holder and gently shake it out; Use a leaf shaped pick to lift the small red leather circle next to it to prevent it from hooking onto the wiring when disassembling the screen.

04
Dismantling old screen: Blade+8+1 combination method

4.1 ◇ Cut open the sealant and apply 8+1 drops of solubilizing aid
Stick the blade tightly around the screen, cut off the sealant first, and then drip a small amount of 8+1 solvent to soften the glue for easy separation.

4.2 ◇ Card stitching, slow work produces fine work
The nail is stuck in the gap, and the card is slowly pushed along the edge. After all the double-sided tape is scraped loose, the entire screen can be removed.

05
Clean up residual adhesive and apply UV glue, and apply sealant to the middle frame

5.1 ◇ Special UV double-sided adhesive for cranks is put into use
Clean up all the old adhesive on the middle frame, apply UV double-sided adhesive specifically for the crankshaft, and apply a circle of sealant around the edges. The amount should be small rather than large - if the adhesive seeps out, it will create bubbles on the new screen.

5.2 ◇ Installing a new screen: align first and then press down
After inserting the cable and aligning the top, gently press down to ensure that the double-sided tape is fully adhered to the middle frame; Push on the battery and perform a power on self-test. If the touch and display are normal, proceed to the next step.

06
Reinstall the small board: plug the charging port first

Before putting the small board back in, first insert the charging port into the hole and fix it, then fasten all the cables in sequence, and finally reinstall the battery - the appearance of the startup logo indicates that the hardware is ready.



07
Upper protective cover, rear cover, and sealant

7.1 ◇ Tighten all screws in place
The speaker, charging port, and small board screws have all been reset; Clean up the residual adhesive on the protective cover and back cover, and then apply special sealant.

7.2 ◇ Cover and flatten, installation completed
Align the back cover with the buckle and lightly press it to fit. If the fingerprint and power button rebound normally, it means the whole machine has been restored. Power on test of various functions, no "wires" on the screen, sensitive touch, normal sound - great success!
