iPhone settings app crashes very frequently after updated to iOS 8.0.2

Hello eitanblu,

After reviewing your post, I have located an article that can help with crashing apps. You may want to consider a restore to factory settings. The article contains a number of troubleshooting steps and helpful advice for the issue you are experiencing.

Use iTunes to restore your iOS device to factory settings

Before you restore your device

1. Make sure you’re using the latest version of iTunes.
2. Use iTunes to back up your device and transfer and sync any additional content to your computer.
3. Turn off Find My iPhone in Settings > iCloud on your device to disable Activation Lock.

Thank you for contributing to Apple Support Communities.
