As early as last year, not long after the release of the iPad mini 6, it was revealed that the tablet had a "jelly screen" problem in the vertical screen state. The so-called "jelly screen" refers to the phenomenon that when dragging the screen, it will be found that the left and right sides of the screen are obviously out of sync, resulting in a feeling of jelly shaking in the visual of the screen.
Recently, a number of users in Colorado Abroad filed a class action lawsuit against Apple, accusing Apple of selling even when it knew that the iPad mini 6 had a defect of "jelly screen", which violated market competition laws, false publicity and fraud.
Regarding the phenomenon of the iPad mini 6, an Apple spokesperson said that "this is the normal behavior of LCD screens, which is common on displays." But although the iPad min 6 and iPad Air belong to the same LCD screen, but the latter is not very obvious, there are repair companies speculating, may be due to the iPad mini 6 display controller board is installed vertically inside the device, not like the fourth generation of iPad Air with horizontal installation.
