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 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?

Where can I buy OLED Screen & Digitizer for Huawei mate 20 pro in India ?

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
