"Green tint" is an issue in which OLED displays seem to glow where they should remain completely dark under certain conditions. It was present in some units of the iPhone 11 series last year, and has now reportedly raised its head again in the new 12s. It may affect any of the flagship line's 4 variants, and has yet to see an update that might fix it.

A display issue increasingly well-known as "green tint" has now been documented in several relatively high-end mobile devices with AMOLED or OLED displays. According to their owners, the Galaxy S10e and Galaxy S10 had it, as did the S20 Ultra and Note 20 Ultra. Similarly, it has arisen in OnePlus' most expensive phone of 2020, the 8 Pro, as it has in some units of the iPhone 11 series. Now, it seems their successors have got it too.

A number of users have reportedly resorted to the Apple support and MacRumors forums to draw attention to this display defect. Some of the resulting posts contain photos that do indeed seem to show the dreaded green tint effect at work.

It is reportedly visible in units of the base iPhone 12 model, as well as its Pro, Pro Max and new Mini variants. Several of their owners have claimed that it is most noticeable in completely dark rooms, at brightness levels of up to 90% or both.

This issue is thought to be due to the failure of the pixels in these OLED panels to switch off completely as they should in order to reproduce black on-screen. In some cases, a software update solves the problem. However, Apple has yet to respond to this new problem with a patch in a new version of iOS.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
