Several users say that the green tint only appears when they have dark mode and night shift activated or if they are in a dark room. Affected users also report that the problem appeared after the release of iOS 13.4, although some did not notice it until after the upgrade to iOS 13.5. At least one user says that the green tint disappeared during the installation of iOS 13.5.5, which is currently in beta, so it seems more likely that it is a software problem. We have contacted Apple for a statement and will keep you posted as soon as we respond. If this is a software issue, the tech giant is required to release an update that will fix it in the future.
A number of iPhone users see a strange green tint on the screens of their devices for a few seconds after unlocking, and it is still unclear what is causing this. Based on complaints posted on Reddit and MacRumors forum, the most affected devices are the iPhone 11, 11 Pro and 11 Pro Max. However, some iPhone X and XS users also seem to be experiencing the problem.
