Set Contact Sync Preferences on Each Device
Review Privacy and Permission Settings
- Find the Contacts or Privacy menu in Settings and toggle sync options for apps that need access.
- Review permissions every few months, especially after app updates or device upgrades, using your phone’s security settings.
- Restrict access for uncommon apps, since sync contacts devices works smoothest when you approve only trusted services.
- Expect to re-authorize permissions if you reset your device or update its operating system, since default restrictions may return automatically.
- Enable two-factor authentication for your main sync account to reduce the risk of unauthorized contact syncs or data leaks.
Customize Sync Frequency
- Access Sync Frequency options in account settings; select real-time or scheduled to match your activity levels, such as daily, hourly, or manual refresh.
- On Android, use the Contacts or Accounts settings to tweak specific sync schedules per app or email account for balance between immediacy and efficiency.
- On iOS, check under Settings > Passwords & Accounts and adjust to push, fetch, or manual for each added account, based on personal preference or battery priorities.
- If you use work profiles or family-shared devices to sync contacts devices, coordinate scheduling to share only necessary contacts—avoid mixing professional and personal lists.
- After changing sync preferences, manually trigger a sync refresh and check a known contact on each device to verify it’s properly updated everywhere.
