Use this guide to replace a broken or defective OLED Screen & Digitizer in your Huawei Mate 20 Pro.
Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.
Opening the Huawei Mate 20 Pro will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water-protection.
Due to the phone’s design, you need to remove the lithium-ion battery in order to remove the screen. Reusing a deformed battery after it been removed is a potential safety hazard. Replace it with a new battery.
Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.
You’ll need replacement adhesive to reattach components when reassembling the device.

Hi there.... My huawei mate 20 pro was water damaged!!! After a while its LCD was displaying green lines and in no time it went blank, but surprisingly the phone works and still receives notifications and incoming calls. I could even answer calls in a blank screen by pretending to swipe as if its on. My question before i buy a replacement screen . Is the LCD really damaged or its the logic board ? This might help me decide on how to proceed with it.
Hi. Did you find out what was wrong? I have the same issue

Hi there,my Huawei mate 20 pro fell on a hard surface,and its started showing very bright sparkling light directly were the fell the hardest rendering ur eyes unable to even see well and also for blank at times. I want to know whether the new screen I intend to buys comes with the sensor coz I believed the is also affected! Or I am going to order for the sensor separately?
try the Huawei app (hicare) select your country and it will show the prices for parts of mate 20 pro, usually screen is too expensive , sometimes they got discounts and promos for different parts, check it out, you can get replacement screens online on ebay or alibaba etc. but wont be good, some got resolution issues, fake sensors, mismatching screen dimensions etc, check the products properly and reviews too before purchasing
