How to Replace the Huawei Mate 10 Pro Screen?

Huawei Mate 10 Pro review

Huawei Mate 10 Pro is launched in November 2017. This flagship smartphone features HiSilicon Kirin 970 chipset. Its OLED screen size is 6 inches with 18:9 screen to body ratio. The resolution of the Huawei Mate 10 Pro display is 1080 x 2160 pixels, which ensure clear and sharp image. If you are a gamer, go for this device.

Both its battery cover and the display is made of Corning Gorilla glass with an aluminum frame running around the sides. The Huawei Mate 10 pro display doesn’t curve around the sides like the Samsung Galaxy S8’s, but its side bezels are still impressively slim. Although the handset is well-built, waterproof and solid, it can get broken if you don’t take good care of it. Today we’ll talk about everything about the Huawei Mate 10 pro screen replacement.

Huawei Mate 10 Pro screen problems (Not common):

  1. Unresponsive Touchscreen

2. Screen Flickering

3. Defect Backlight.

Solutions to Huawei Mate 10 Pro screen issues:

A. Wipe cache

Try to wipe the cache partition to see if it makes a difference. Turn off your phone, press and hold the volume up and the power button together. Keep holding the keys when the Huawei logo appears. As soon as the screen turns black, release the keys. Wait for several seconds, you’ll see EMUI on the screen. That means you’ve reached the recovery mode. Press volume down button to select “Wipe cache partition” and press power button to confirm.

B. Reconnect the screen

In some cases, the problem of the touchscreen and the display is caused by overheating. We can open the back cover and disconnect the battery from the motherboard for a while. Then reconnect the battery and check whether the problem solved.

C. Replace the defect screen

In most cases, the problems are caused by the defect of screen flex cable. Breakage of the flex cable will cause a short circuit and open circuit. We have to disassemble the device and check out whether the LCD ribbon got burned by overheat. And although the Mate 10 Pro display uses a Corning Gorilla Glass protection, its display still could be cracked if we drop it onto the ground accidentally.

The Huawei Mate 10 pro display is very difficult to remove. The adhesive below the screen is extremely strong and can not melt down. That’s why this flagship smartphone is waterproof. And the frame will get scratched when you try to cut below the screen with a knife or something like that. The best way to remove the damaged screen is to smash it and pry off the glass piece by piece.

And don’t even think about repair only the front glass of Huawei Mate 10 pro. It’s even difficult. It needs profession machine and skills. And it’s not suitable for DIY.

It is difficult and perhaps dangerous to replace the Mate 10 pro display or front glass. So, it is recommended that you buy a Huawei Mate 10 Pro screen replacement with the frame. It makes the repair procedure easier and safer.

Step 7 Test the new Huawei Mate 10 pro display

  3. If the test passed, separate the battery, the motherboard, and the display.
  4. Before testing, don’t paste the battery adhesive and the screen adhesive. If you got a Huawei mate 10 pro screen replacement with the frame which is mention above, you can pass the step of installing the display screen.
