How does Lenovo s920 restore the default contact photos?

Hello, thank you for choosing Lenovo products.

Sorry, the replaced contact photo cannot be restored to the default avatar, but you can enter the contact editing interface to reset other avatars. If you need to restore to the default avatar, I suggest you try to delete the contact and create a new contact for storage.

Thank you for your support of Lenovo. I hope the above reply is helpful to you. Wish you a happy life!
