Is there a way to sync contacts on the iPhone with both Google Contacts and iCloud without creating duplicates?

Yes, you can sync contacts on your iPhone with both Google Contacts and iCloud without creating duplicates by following these steps:
1. Sync Contacts with iCloud:
•Go to "Settings" on your iPhone.
•Scroll down and tap "Contacts."
•Under the "Accounts" section, tap "Add Account."
•Select "iCloud" and sign in with your iCloud credentials or create an iCloud account if you don't have one.
•Enable the "Contacts" toggle to sync your iPhone contacts with iCloud.
2. Sync Contacts with Google Contacts:
•Go to "Settings" on your iPhone.
•Scroll down and tap "Contacts."
•Under the "Accounts" section, tap "Add Account."
•Select "Google" and sign in with your Google account credentials.
•Enable the "Contacts" toggle to sync your iPhone contacts with Google Contacts.
3. Merge Existing Contacts:
•After syncing with both iCloud and Google, it's essential to ensure that your existing contacts are merged to avoid duplicates.
•Open the "Contacts" app on your iPhone.
•Tap "Groups" in the upper-left corner of the screen.
•Uncheck "All iCloud" and select only "All [Your Google Account Name]" and "All on My iPhone." This will display all your contacts from both iCloud and Google.
•Now, go through your contacts and manually merge any duplicates. To do this, open a contact, tap "Edit," and then scroll down to see if there are duplicate entries. If you find duplicates, you can merge them by tapping "Link Contact."
By following these steps, you can sync your iPhone contacts with both Google Contacts and iCloud while minimizing the chances of creating duplicates. However, it's essential to periodically check and manage your contacts to ensure that duplicates do not accumulate over time.
Duplicates also shouldn't be a problem - https://applenapps.com/delete-duplicate-contacts-on-iphone/ as they can be easily cleaned up.

Google does two things that have caused massive duplication of contacts: 1. If you have anyone with three words in their name, in other words when you combine their forename & surname, if there are more than 3 words, Google decides to put some of the names into the "middle name" field. This changes the contact enough to cause a dup. This will happen with a forename like "George W." also; 2. If you stored someone's address details using the wrong country format for that person, i.e. you used the default US format for someone who lives in Germany, then Google will switch the format for you causing another duplicate when you sync. I gave up trying to sync to both.
