Since last year, iPad mini users have successively found that their tablets will appear "jelly screen" phenomenon, that is, the left and right sides of the screen are not refreshed under the scrolling operation, for example, when scrolling vertically, the text display is slightly uneven, and the text on the left side of the screen seems to be slightly behind the text on the right side of the screen when scrolling. But for this situation, Apple gave a reply: this effect is "the normal behavior of the LCD screen", and refuses all the requirements of the user to recall the product, provide compensation, upgrade the software to improve the "jelly screen" and so on. Such replies and operations are also really confusing.
As a result, Christopher Bryan, a citizen of Colorado in the United States, chose to file a class-action lawsuit against Apple, arguing that Apple had fraudulent marketing behavior, and Apple chose to continue to sell the product knowing that the sixth-generation iPad mini had a "jelly screen" problem. Until now, Apple has not fixed the problem of "jelly screen", nor has it modified the marketing materials to inform the existence of problems, violating market competition laws, false publicity and fraud.
Although Apple Jane insisted that the "jelly screen" is a normal situation, after dismantling the overseas professional agency iFixit, it was found that the uneven display of text on both sides of the sliding screen should be a design defect, rather than the so-called "LCD normal phenomenon". Through design inference, it may be related to the iPad mini6 screen scanning direction and display control panel position, iPad Air due to the use of different controller layouts, so there is no "jelly screen" phenomenon, the problem can not be completely solved through software upgrades.

According to foreign media reports, the class action lawsuit claims compensation for any user in the United States who purchases a sixth-generation iPad mini, the amount of compensation is yet to be tried, and the proposed class entity still needs to be certified before the class action lawsuit can proceed.
