[Asia Economy Reporter Han Jinju] Apple is aware of display issues such as the lightning phenomenon, green algae, and gray screens on the iPhone 12, and plans to resolve them through software updates.
On the 18th (local time), according to a document obtained by IT media MacRumors that Apple shared with authorized service providers, Apple is aware of consumer complaints about screen flickering and green and gray color changes on the iPhone 12 display, and is currently investigating the matter.
In an official letter sent to technicians at authorized service centers, Apple advised, "Rather than providing service for iPhones affected by the (display issue), at least ensure they are running the latest iOS version." This indicates Apple's confidence in resolving the problem through software updates.
Apple also experienced the green algae phenomenon, where the screen shows a green tint, on the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max models. Apple resolved this issue through the iOS 13.6.1 update.
Since the launch of the iPhone 12, display-related issues have been raised multiple times on Apple communities. The same OLED display is used in the iPhone 12 mini, Pro, and Pro Max models, which may also be affected. MacRumors explained, "Users have experienced screen flickering issues on iOS versions 14.1, 14.2, and 14.3."
In domestic iPhone cafes, display-related issues have been continuously reported, including the so-called "lightning phenomenon," where the screen flickers when the brightness is set low while watching videos or web surfing; the "black" phenomenon, where the screen goes dark when brightness is below 50%; light leakage on the sides or bottom of the display; the "cherry blossom screen," where the screen appears reddish; and the "green algae screen," where the display color shows a green tint. Regarding these, Apple has officially stated, "We are aware of a small number of reported cases and are currently investigating."
