Hi Loveisdead,
It sounds like you're iPhone is unable to complete the update or even start it. I would start by qutting the Settings app:
Force an app to close in iOS
1. Press the Home button two times quickly. You'll see small previews of your recently used apps.
2. Swipe left to find the app you want to close.
3. Swipe up on the app's preview to close it.
When you have done that restart the device and test the issue again:
iOS: Turning off and on (restarting) and resetting
If that still doesn't work you can always use iTunes to update your phone:
Update the iOS software on your iPhone, iPad, and iPod touch
If you can’t update wirelessly, or if you want to update with iTunes, follow these steps:
- Install the latest version of iTunes on your computer.
- Plug in your device to your computer.
- In iTunes, select your device.
- In the Summary pane, click Check for Update.
- Click Download and Update.
If you don't have enough free space to update using iTunes, you'll need to delete content manually from your device.
Find out what to do if you get other error messages while updating your device.
Thank you for using Apple Support Communities.
Cheers,
