The company seems to be aware of this situation, which shows green in some units.
The Huawei Mate 20 Pro is one of the best smartphones released this year, but despite its high quality, we have reported some cases of problems on our screen (through XDA developers).
Several reports of commented Huawei Mate 20 Pro users who discovered a problem on the device screen come into the network, in particular light spill or bleeding, which, as you see in the images, shows an obvious green on the screen, mostly on its sides, when viewing dark background content.
At the moment, this decision is not disturbing, because it's obviously a little affected unit, and in fact in some cases it is more serious than others, where they say that some users have not even noticed.
Some believe that the issue is in OLED panels from LG, although some others indicate that this might be due to screen-level drying.
So far, Huawei has not released a statement on the subject, but apparently they are aware of this issue, as one of the company's official forums commented that the OLED screen technology, due to the curved edges of the device, can look at a certain color from some angles, indicating that if the color range affects the normal use of the smartphone, it is advisable to transfer it to the authorized service center for help.
Therefore, we will be careful to see if Huawei says anything about it, and to make sure they continue to report a few things.
