Fix account sync issues

Important: For sync to work, you need an internet connection.

To test your connection, open a browser (like Chrome or Firefox) and load a website. If the website doesn't load or you can't connect, learn about connecting to a Wi-Fi network or connecting to mobile data.

Make sure that you can sign in to your Google Account in other ways and on another device. For example, try checking your Gmail using your computer's browser.

• If you can sign in, the issue is with your phone. Try the next solution.
• If you can't sign in, your account may have an issue. Get help signing in to your account.
