How to get rid of "Finish Setting Up Your iPhone" badge?
After restoring my iPhone from a backup using iTunes, I was already signed into iCloud with my Apple ID. Yet I had this "Finish Setting Up Your iPhone" message and badge on the Settings app, which was super annoying. Whenever I tried to "finish" the setup, the set up would never finish because I was already signed in!

To resolve this (make sure you have a backup of your data before proceeding!), do the following:


Settings > Your Name > Sign out


Enter your password (this will turn off Find My iPhone which is ok)
You will be asked what info your want to keep on device. I didn't keep anything because I backed up my phone before this using iTunes.

Settings > Finish Setting Up Your iPhone


Follow the process, sign in with your Apple ID and password and finish all the steps.



Now everything works and there is no more red notification icon on the settings app on the home screen!
