D habitude mes contacts s enregistrent sur le téléphone et Google en sauvegarde mais j ai un contact qui s est enregistré sur le téléphone seul et impossible de le mettre en sauvegarde sur Google

Dès solutions ? 

Usually my contacts are saved on the phone and Google backs up but I have a contact who has registered on the phone alone and can not save it on Google

Solutions ?

Write it down, delete the contact and add the contact to the address book again?

Or goto contacts.google.com and add the contact?

You can spend a lot of time finding out how come.

Find a solution is often easier than knowing the exact cause of this behavior.

However it would be interesting to know.
