Strange lighting and a flickering screen
Basically, OLED screens ensure excellent colors – and, depending on the design, rich black, as the pixels are not illuminated. At the moment, however, many users are reporting that their display is lit green or gray. This does not seem to occur constantly – and is subject to fluctuations: Sometimes it appears stronger and sometimes only weakly. Those affected report an unpleasant flickering that can already be seen when the brightness of the screen is set at around 90 percent or below. All models of the iPhone 12 are affected by the problem, and the status of the software does not seem to play a role: Initial feedback reports that the phenomena described above also appear in the beta of iOS 14.3.
Apple assumes a software problem
Loud MacRumors Apple has already taken notice of this problem – and has instructed authorized service providers to stop servicing faulty devices. Instead, customers should be informed of a future software update – so Cupertino does not seem to be assuming defective panels, but wants to counteract this with a new version of iOS. Apple could be right: The iPhone 11 series was affected by a similar problem – only an update to iOS 13.6.1 provided a remedy.
