Why can't the SMS contacts in my mobile phone delete Lenovo A390t?

Dear Lenovo mobile phone users, hello!

The SMS contact you quoted could not be deleted. What is the specific situation?

To delete a message or contact conversation, just press and hold the message or contact conversation directly-Delete.

If it is abnormal, you mean "the contact can't be deleted", that is to say, after all the information in the contact session is deleted, the contact is still displayed in the information interface, which may be caused by system abnormality.

I suggest you try to back up the important information of your mobile phone first, and then restore the factory settings of your mobile phone to see if it can be improved. If the problem still exists, we suggest you take the time to go to the local Lenovo after-sales service center and ask an engineer to help you detect and solve it. You can log in to official website to check the address:/Lenovo/WSI/Station/ServiceStation/default.aspx? intcmp=MIDH

Thank you for your support of Lenovo. If there are other problems in the use of the follow-up products, please inquire and understand through Lenovo's official service and support website and Lenovo Music Ask Bar. Wish you a happy life!
