Some Huawei Mate 20 Pro users are seeing a green tint on the display
Regardless of how you feel about Huawei, it’s clear that their Mate 20 line of smartphones are among the best of 2018—and with good reason. Huawei pulled out their biggest guns with the Huawei Mate 20 and the Huawei Mate 20 Pro: a triple-rear camera setup, the 7nm-based Kirin 980, 40W wired fast-charging capabilities… And with Huawei’s worldwide brand recognition, the phones are sure to become a sales success. But obviously, no phone is perfect, and some issues are likely to slip past quality assurance once in a while. And the Achilles’ heel of the Huawei Mate 20 Pro is—apparently—its display.
According to reports from several users, it appears that the display on certain Huawei Mate 20 Pro units has a light bleeding issue which causes a very noticeable green tint. Said tint is most noticeable around the edges of the display when viewing content with darker backgrounds, but some units have it worse than others.
It isn’t clear what causes the issue. The Huawei Mate 20 Pro uses an OLED panel from either LG Display or BOE (LG EA9151 or BOE R66451), and users can confirm which panel their device uses by using an app like DevCheck. Some users believe that the issue is due to the LG OLED panels, while others are saying it could be caused as a side effect of the screen’s glue drying out. For what its worth, our TK Bay’s review unit isn’t affected by this issue.
A Huawei UK Community Forum Manager (via GSMArena) responded to the complaints with the following comment, “the Mate 20 Pro uses an industry-leading flexible OLED screen featuring special design curved edges for an enhanced visual experience and holding comfort. This may lead to slight discoloration when viewed from different angles.” Note, however, that this isn’t an official statement from a Huawei spokesperson, so we are still looking forward to an official response from Huawei PR.
As of now, we recommend waiting on a response from Huawei in case you’re worried about playing the screen lottery.
