You may be sick of trying to figure out how to navigate your phone after Apple's iOS 7 update, but some of its new bells and whistles are actually making some people ill.
Disgruntled iPhone and iPad users have taken to the company's forums to gripe about the software's features.
"The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache," one user wrote. "It's exactly how I used to get car sick if I tried to read in the car."
Others chimed in, saying that looking at the apps when they zoom in and out is making them dizzy, hurting their eyes, and causing headaches and motion sickness.
"I had severe vertigo the minute I started using my iPad with iOS 7," another user wrote on the support forum. "Lost the rest of the day to it... And not happy at all."
The fake 3D parallax effect, which causes the background and icons to shift with the movement of the device, was another criticized addition. Users also complained about the juxtaposition of the thin black text against the bright white background.
You can turn off the parallax feature. Go to "Settings," and then "General" and "Accessibility," and turn on "Reduce Motion."
However, there is no option to disable the zooming animation.
As of now, there is no Apple-sanctioned way to downgrade your device's operating system. People said they went so far as to buy a new iPhone 4, 4S or 5 that had an older version of iOS installed on it.
