In some cases, you may have to delete the Google account on your phone for troubleshooting purposes. (Don't worry, you can always re-enable it after your phone is back in working order.)
The easiest way to do this is through the main Settings menu on your phone:
- Open the Settings app.
- Scroll down to the Accounts section on your Settings menu and select Manage Accounts.
- Click on the Google account you're currently signed into and select Remove Account.
