iOS 7 was released to all Apple mobile users on Sept. 18. Since that time, it has received largely positive reviews from customers who have downloaded the free update to their devices. iOS 7 marks the biggest change in Apple's mobile operating system since it debuted the App Store. However, no major software update is without its problems. Below is a list of 5 glitches with iOS 7 and how to fix them, courtesy of CNN.

iMessage Failure: Apple has said that it is aware of an ongoing issue that is causing text messages sent via the iMessage app to not reach the sender.

"We are aware of an issue that affects a fraction of a percent of our iMessage users, and we will have a fix available in an upcoming software update," Apple said in a statement e-mailed to media outlets. "In the meantime, we encourage any users having problems to reference our troubleshooting documents or contact AppleCare to help resolve their issue. We apologize for any inconvenience this causes impacted users."

Unfortunately the fix for this one is simply to wait until Apple pushes its update.

Animation Sickness: Some people have been complaining that the various zoom animations on iOS 7 are triggering pre-existing motion sickness issues. While some medical professionals deny that this is true motion sickness, it's doubtful the people complaining are lying about experiencing some kind of discomfort.

The fix is going to Settings > General > Accessibility > Reduce Motion and the zoom will go away.

App Issues: When Apple updated its iOS, many apps that rely on hardware functions like the camera got confused and started kicking people out and logging htem off. Snapchat and Mailbox were frequent offenders, according to CNN, which combed Apple's message boards.

The fix is simply to wait until the app's developers update to be compatible with iOS 7. Luckily many of the major ones have already done so. If you find yourself with an app that is still defective, it might be time to bring your business elsewhere to a different app.

Bypassing the Lock Screen: Although this has already been fixed in the iOS 7.0.2 update, it's worth noting that when the update first came out, users found a way to bypass the lock screen by accessing the control panel.
