Why is there always a red circle 1 on the SMS folder?

Hello, this indicates that you have another unread email. Please look carefully. If you can't find unread information, you'd better check whether there is unread information in the SIM card storage. If not, apply the settings, find the "information" level, and then click the settings such as clear cache and clear data, and that's it.

I hope it will help you, please adopt it. Thank you.
