It didn't take Apple very long to update iOS for iPhone 4-5 and iPad 2-4 to fix the way some hackers found to bypass the Lock screen password. In one week it was able to fix the bug along with re-introducing the Greek keyboard option for password entry. However, there's another problem with flu-like symptoms caused by iOS 7, we call iFlu.
A vulnerability allowed hackers to get through the lock screen to access the user's photos. Launching the timer app while holding down the power button and cancelling the shut down allowed access to the multitasking menu and camera roll where photos could be seen and deleted. The iOS 7.0.2 update closes that hole.
In the meantime iOS 7 users have noticed another vulnerability that makes them sick, literally.
Apple Support forum members claim feel motion sickness (See-Sick syndrome), headaches vertigo, dizziness and nausea from the zooming animations throughout iOS 7.
Animation includes icons to flying in to the Home screen when you unlock your iOS device or e zooming on the background wallpaper when opening and closing folders.
The are asking Apple for a way to disable the animations that are causing Visually induced motion sickness (VIMS).
Some suggest s those who are affected to file a bug report with Apple, mentioning bug number 15074144 so the duplicate reports can be tallied. The Parallax setting can be turned off, which some say doesn't make a big difference. Settings > General > Accessibility > Reduce Motion.
There are no reports stating that looking at an iPhone running iOS 7 while on a rocking boat, reducing sea sickness.
