Huawei P20 Screen Repair: How to Fix Cracks and Display Issues
A damaged phone screen can make daily use difficult, especially when your Huawei P20 is still working well in other areas. The Huawei P20 is a stylish and reliable smartphone, but like any phone, its display can get cracked, scratched, or damaged after a fall. A broken Huawei P20 screen does not always mean the phone is useless. In many cases, the screen can be repaired or replaced, and the phone can work smoothly again.
The Huawei P20 screen is one of the most important parts of the device. It controls how you view apps, photos, videos, messages, and websites. It also handles touch response, which means even a small crack can sometimes affect how the phone works. Some users only face cosmetic damage, while others deal with black spots, lines, flickering, or touch problems.
In this guide, we will explain everything you need to know about Huawei P20 screen repair. You will learn about common screen problems, possible repair options, when replacement is needed, and how to protect your screen after repair.
Why Huawei P20 Screen Repair Is Important
Many people continue using their phone after the screen cracks. At first, a small crack may not look serious. The phone may still turn on, and the touch may still work. However, screen damage can become worse over time. Dust, moisture, and pressure can enter through cracks and damage the display or internal parts.
A cracked Huawei P20 screen can also affect user safety. Broken glass can be sharp, especially around the edges. If you use the phone daily, tiny glass pieces may hurt your fingers. A damaged screen can also make it hard to read text, watch videos, or use apps properly.
Screen repair is important because it restores the phone’s look, touch performance, and display quality. If the phone has no major internal damage, replacing the Huawei P20 screen can make the device feel almost new again.
Common Huawei P20 Screen Problems
Huawei P20 screen issues can appear in different ways. Some problems are easy to notice, while others become worse slowly. Understanding the problem can help you decide whether you need glass repair, full screen replacement, or professional inspection.
Cracked Glass
Cracked glass is one of the most common problems. It usually happens after the phone falls on a hard surface. Sometimes the crack is small and stays in one corner. Other times, the crack spreads across the whole display.
If the touch and display still work, the damage may look minor. However, cracked glass can weaken the screen structure. With time, the crack can spread and affect the touch layer or display panel.
Touch Screen Not Responding
A damaged Huawei P20 screen may stop responding to touch. This can happen in one area or across the entire screen. You may tap an app and get no response. Sometimes the screen may open apps by itself or type random letters.
Touch problems usually mean the digitizer is damaged. The digitizer is the part that reads finger movement. If this part is not working correctly, screen replacement is often needed.

Black Screen or No Display
Sometimes the phone turns on, but the screen stays black. You may hear notification sounds, feel vibration, or see the charging light, but the display does not show anything. This can happen after a strong impact or internal display damage.
A black Huawei P20 screen may mean the LCD or OLED display has failed. It can also happen if the screen connector is loose, but this should be checked by a technician.
Lines on the Display
Vertical or horizontal lines on the screen are another common issue. These lines may be white, green, purple, or black. They usually appear after pressure damage or a fall.
Lines on the Huawei P20 screen often show that the display panel is damaged. If the lines do not go away after restarting the phone, a screen replacement may be required.
Flickering Screen
Screen flickering can make the phone difficult to use. The display may blink, flash, or change brightness randomly. This can happen because of software problems, display damage, or a loose connection.
If flickering starts after a fall, it is likely a hardware issue. If it starts after an update or app installation, it may be software-related.
Black Spots or Ink Marks
Black spots, purple marks, or ink-like patches usually mean the display has internal damage. These marks may start small and spread over time. This type of damage normally cannot be fixed with simple glass repair.
When black spots appear on the Huawei P20 screen, full screen replacement is usually the best solution.
Can You Repair a Huawei P20 Screen Yourself?
Some people think about repairing the screen at home to save money. While DIY repair is possible, it is not easy. The Huawei P20 screen is attached to the phone body with adhesive. Removing it requires heat, tools, care, and experience.
If you do not have the right tools, you may damage the battery, frame, flex cables, fingerprint parts, or other internal components. A small mistake can turn a simple screen repair into a costly phone repair.
DIY repair may be suitable for someone who has repaired phones before. However, for most users, professional Huawei P20 screen repair is the safer option. A repair shop can remove the damaged screen, test the phone, install the new screen, and check touch and display quality before returning the device.
When Does Your Huawei P20 Screen Need Replacement?
Not every screen issue requires full replacement, but many physical damages do. If the glass is cracked but the display and touch are perfect, some repair shops may offer glass-only repair. However, glass-only repair is more complex and not always available.
Full Huawei P20 screen replacement is usually needed when the display has lines, black spots, dead pixels, no touch response, flickering, or a black screen. Replacement is also recommended if the glass is badly broken and pieces are coming off.
A full screen assembly usually includes the display and touch digitizer together. This makes repair more reliable because both the visual display and touch function are replaced at the same time.
Huawei P20 Screen Repair Process
A professional repair process usually starts with checking the phone. The technician will test the display, touch response, charging, buttons, cameras, and overall condition. This helps confirm whether only the screen is damaged or if other parts also need attention.
After inspection, the damaged Huawei P20 screen is carefully heated to soften the adhesive. The technician then removes the broken display using special tools. This step must be done slowly because internal cables and parts are close to the screen.
Once the old screen is removed, the frame is cleaned. Any leftover glass or adhesive is taken out. The new screen is connected and tested before final installation. This test checks brightness, colors, touch response, and screen alignment.
After testing, the new screen is fixed in place with adhesive. The phone is pressed carefully so the screen sits properly. A final check is done before the repair is complete.

Original vs Replacement Huawei P20 Screen
When repairing your phone, you may see different screen quality options. Some screens are original, while others are aftermarket or compatible replacements. The quality can affect brightness, color, touch response, and long-term durability.
An original Huawei P20 screen usually gives the best display quality and touch performance. It is closer to the screen that came with the phone. However, original parts may cost more.
Aftermarket screens are often more affordable. Some good quality replacement screens work well, but lower-quality parts may have poor brightness, weak touch response, or color differences. Before repair, it is better to ask what type of screen will be used.
Choosing a reliable screen is important. A cheap screen may save money at first, but it can create problems later.
How Much Does Huawei P20 Screen Repair Cost?
The cost of Huawei P20 screen repair depends on several factors. The main factor is the quality of the replacement screen. Original or premium-grade screens usually cost more than basic aftermarket screens.
The repair cost can also depend on your location, repair shop, labour charges, and whether the phone has extra damage. If the frame is bent, the battery is swollen, or internal parts are damaged, the final cost may increase.
It is always best to get a proper quote before repair. Ask whether the price includes the screen, labour, testing, and any warranty. A trusted repair shop should explain the cost clearly.
Signs You Should Repair the Screen Quickly
Some screen problems should not be ignored. If your Huawei P20 screen has sharp broken glass, black spots, flickering, or touch issues, it is better to repair it quickly. Waiting too long can make the damage worse.
You should also repair the screen soon if moisture can enter through cracks. Even a small amount of liquid can damage the display, motherboard, or charging port. If the screen is lifting from the frame, do not press it hard. This can damage internal parts.
If your phone is still valuable to you, repairing it early can help avoid bigger problems.
Tips to Protect Your Huawei P20 Screen After Repair
After screen replacement, you should protect the new display from damage. A good tempered glass protector is one of the easiest ways to protect the Huawei P20 screen. It adds an extra layer against scratches and small drops.
You should also use a strong phone case with raised edges. Raised edges help protect the screen when the phone falls face down. Avoid keeping your phone with keys, coins, or sharp objects in the same pocket.
Try not to place heavy items on your phone. Pressure can damage the display even if the glass does not crack. Also, avoid using the phone with wet hands or in very humid places.
Should You Repair or Replace Your Huawei P20?
This depends on the condition of your phone. If your Huawei P20 is working well and only the screen is damaged, repairing it is usually a good choice. Screen repair can be cheaper than buying a new phone.
However, if the phone has many other problems, such as poor battery life, charging issues, water damage, or motherboard faults, you should compare repair cost with the cost of a newer device.
For many users, Huawei P20 screen replacement is still worth it because the phone has a good design, strong camera, and smooth performance for basic daily use.
Choosing the Right Repair Shop
A good repair shop can make a big difference. You should choose a technician who has experience with Huawei phones. Ask about the screen quality, repair time, and warranty before handing over your device.
A trusted repair shop should test the phone before and after repair. They should also explain the difference between original and aftermarket screen options. If a shop gives a very low price without explaining the quality, be careful.
Good repair is not only about replacing the screen. It is also about making sure the phone works properly after the repair.
