Apple acknowledged display defects in some models of the iPhone 12 series and started an investigation, the US IT media McRumers reported on the 18th (local time).

According to a document delivered by Apple to an authorized service provider, Apple is aware of flickering screens and changes in green and gray display colors reported on some models of the iPhone 12 series and is conducting an investigation.

In addition, in a document sent by Apple to authorized service center technicians, “you should make sure you keep the latest version of iOS rather than service the affected iPhone.”

Foreign media said, “It suggests that Apple can solve the display problem through software update rather than hardware.”

On the other hand, the green algae of the display occurred in the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max models, but Apple has resolved the problem through the iOS 13.6.1 update.

Apple’s product quality controversy isn’t just for the iPhone 12 series. In some models of the’Apple Watch SE’, which is an entry-level smart watch for the first time in September, the phenomenon that the screen burned due to heat of unknown cause occurred in Korea and the United States.
