The interface also makes generous use of animation. As folders and apps are opened and closed, the screen zooms in and out. When moving among apps, transitions zoom and slide. Full screen slides are common. On the home screen, there's a 3D parallax effect that makes the icons appear to float and move as if detached from the background.
All that movement can be overwhelming for some users, or worse.
"I thought I was going crazy today after I updated my phone and I noticed I was feeling queasy every time I used it," wrote knphoto10 in an online discussion. "Now I see I am not alone! I just used my phone for about 20 minutes and now I feel like I'm going to vomit."
After researching the problem for three days, another discussion contributor reported finding only one solution: Get a new phone and refuse to upgrade.
