Q: How do I troubleshoot account syncing issues with Google Account Manager 5.1-1743759? A: Check that the account is correctly configured, and that the syncing settings are enabled. Also, ensure that the device's date and time settings are correct.
Google Account Manager is not an app you "use" in the traditional sense; it is a background system service. Its sole purpose is to handle authentication tokens between your Android 5.0 device and Google's servers. When you enter your Gmail address and password into a Lollipop phone, you are not logging into individual apps—you are logging into the Account Manager. It then securely stores an encrypted token, allowing Gmail, YouTube, Drive, and the Play Store to verify your identity without asking for your password repeatedly. i--- Google Account Manager 5.1-1743759 -Android 5.0
