I'm sorry for the inconvenience.
Your situation may be that there are the same contacts in your mobile phone and SIM card. You can display the contacts in your phone or SIM card separately by opening the contacts-clicking the menu button-and then selecting the display option.
In addition, you can also realize the duplicate removal function of contacts through Lenovo music synchronization, and automatically and intelligently merge contacts with identical local numbers and names during synchronization. You can delete all the contacts on your mobile phone after synchronization, and then synchronize them to your mobile phone again to achieve duplicate removal.
For more information about music synchronization, please visit.
Thank you for your support to Lenovo and wish you a happy life!
