An issue with LCD screen scrolling in an iPad mini in portrait orientation caused by Apple's engineering choices will be reduced, but not fixed, in the forthcoming iPad mini 7.
The jelly scrolling issue was spotted soon after the iPad mini 6 launched in 2021, and users' experiences were later borne out by a teardown that confirmed it as being caused by Apple's engineering choices.
Jelly scrolling is caused by a small refresh delay as the lines of a display are updated. It's common on certain screen types, though usually less noticeable, and it is typically only seen in portrait instead of landscape orientation because of how LCD controllers generally orientate refreshes on the long-axis, and when fast-scrolling.
Now according to leaker "Instant Digital" on Chinese social media site Weibo, the issue has been improved. "Instant Digital" does not have a lengthy track record in Apple leaks, but it's also reasonable to expect that Apple would work to address the complaints.
That change of screen assembly direction does fit with iFixit's supposition that the position of components is exacerbating the issue.
The leaker also says that "the front camera seems to have also been upgraded, but the specifics are not very clear." He or she then further claims that the iPad mini 7 will use the A16 Bionic processor, as used in the iPhone 14 Pro.
