Just last week official sales of the new iPad Mini 6 tablet launched, and it already has problems.
Users are complaining about "jelly" screen. This is when different sides of the display are scrolling through the picture at different speeds, causing the image to wobble. What this looks like live - shown by Dieter Bohn of The Verge:
After that, even people who have never noticed the problem noticed it before. And it's annoying: users not only look at the smoothness of the picture, but also spoil their eyesight this way.
What is interesting is that "jelly scrolling" occurs in mostly only in portrait orientation.
It's not yet clear what caused this - hardware or software problem. The media has contacted Apple for clarification, but the company is still not responding to user complaints and not commenting.
