Ipad Mini 6 jelly scrolling problem

First, it probably is not an issue of the same magnitude on all iPad mini 6 units, only affecting some units badly enough to cause user complaints.

Secondly, it is important to understand that everyone has unique vision and some might not be distracted by jelly scrolling, while it might drive others nuts.

I've had a mini 6 for a couple of weeks, and have never seen it on anything. Not even on ebooks with scroll. Not even on large web pages. Hubby got his one day before I got mine, and he says he's never seen it.

The only time we've see it is on tv, with a web page, and trying to make it 'jelly'. So maybe it's something they caught in the early-early models. For us it's a complete non-issue so far.

I suspect there is a tiny bit of jelly rolling with almost all similar types of displays, regardless of manufacturer, due to the way the screens are updated. From what I understand, the screens are updated line by line starting on one side of the display (when in portrait mode) and progressing across to the other side of the screen. If you took a super-slow motion video of the process it would be very noticeable. Under certain viewing conditions this process can make the line of pixels across the screen appear to be slanted for a fraction of a second. However, the process is happening so fast in real time our eyes rarely will perceive it on a good display.

I checked my iPad mini 5 after I heard of this on the mini 6 and under some lighting conditions with certain scrolling speeds I can see it, but it is not nearly as pronounced as in the posted videos. On my mini 5 I have to look for it to see it.

Video specs can also cause some strange things to happen due to frame rates. If you have ever seen a car wheel or a wagon wheel in a movie appear to switch from rotating forward to rotating backwards even when the car or wagon is still moving forward, that is due to the frame rates of the video being refreshed at just the wrong time to create that illusion. Same with video taken of airplane props when the airplane is in the air. You can see a lot of distortion. That is all due to the physics of how video camera shutters work. So whether the jelly rolling looks exactly like the videos is questionable as I've never seen it that bad in person, but it wouldn't surprise me if it is that bad in rare cases.

Having said that, for me I don't think the jelly rolling would be all that distracting for myself as I rarely scroll that fast, and when I do scroll fast it is usually for a very brief period of time. But for others, it might be quite a distraction.

My best guess is that there was a batch or more of the displays that were bad. That doesn't mean every display in the batch was necessarily bad, but some were. Hopefully if that is the case Apple will exchange those units. For those who are hesitant to buy a mini 6 because of this issue, they can go look at a unit in the store and decide if they want it or not. If one buys a mini 6 online, be sure to buy from a retailer with a good return policy. Some retailers like Amazon have a no questions asked return policy of around 15 or more days. Apple offers a return policy too for a few days.

I am suggesting to anyone I know who wishes to read ebooks regularly on an Ipad Mini 6, to hold off and either consider getting a Mini 5 (which I have--and due to the controller being mounted the other way, has a low/minimal jelly scrolling issue), or look at other options.

Even if a unit has jelly scroll issues, you can read ebooks by turning the whole page at a time rather than scrolling, which would render jelly scrolling a non-issue. Granted it might not be the preferential way someone wants to read, but it wouldn’t be affected at all by jelly scrolling. Web surfing though is going to be an issue, and any other app that uses scrolling.

I definitely agree that the iPad mini 5 is terrific for ebook reading. I love mine. And to be truthful, I find holding my iPad Air 2020 more difficult due to the tiny bezels. I keep activating stuff on the screen because there is no place to rest my thumb. I don’t have to worry about that on my iPad mini 5 though. I understand the allure of small bezels since they give you a bigger screen in the same over all size package as you get with larger bezels. But they make reading for me a bit harder. I would love to see an iPad mini with the larger bezel at the bottom keeping the button, and smaller bezels on the other three sides. For reading, I prefer a design like my Oasis 3 with a lot of bezel for my thumb on one side. Of course Apple will never build an iPad mini like that.

I have the new Mini 6 and the Mini 5. Using Goodreader for pdfs and Marvin for epub. I find that the jelly issue is the same on both the 6 and the 5. It doesn't really bother me, by the time I get to that part of the screen it has settled down, but I realize it could be a real problem for some.

Fair enough. Agree with all of that--except the bit about Ipad Air, which I have no experience with.

Isn't it funny how the ergonomic details of an older device can sometimes make it more effective--for certain purposes such as book reading--than a newer device that has the latest tech?
