The dialog box still exists after Lenovo A690 SMS is deleted. How to delete it? What's going on here? I didn't redo the system.

Dear Lenovo mobile phone users, hello!

I am very sorry for the inconvenience caused to your mobile phone.

Normally, delete every message. You can enter a contact session and press and hold the message-Delete. If you need to delete this contact session, please press and hold Contact Session-Delete.

If all the short messages in the contact conversation are deleted, or the contact conversation will also be displayed in the information interface after the contact conversation is directly deleted by long press. It is recommended that you try the following methods:

1, the information program may be temporarily abnormal, try to restart the phone;

2. Enter System Settings-Applications-All Devices, find the program related to "Information", and click Clear Data to observe and use. (Pay attention to backup important contacts, text messages and other materials)

3. It may be that some installed third-party software, such as third-party SMS software, has an abnormal conflict, so try to uninstall it. Or after backing up the important information of the lower fuselage, restore the factory settings to see if it can be improved.

If the problem still exists, it cannot be effectively solved. We suggest that you take the time to go to the local Lenovo after-sales service center and ask the engineer to help restore the system.

The address can be registered in official website:/Lenovo/WSI/station/service station.

I hope the above reply will help you, and I wish you a happy life!
