Have you read the iphone information or have a number?

Iphone information has been read or has a number. The solution is as follows:

Whether the iPhone information has been read or has a number may be caused by a BUG in the system version, unread information or turning on the notification flag function. First, you can try to restore the system version and fix possible bugs. Second, carefully check whether there is unread information. If you confirm that there are no unread messages but the number is still displayed, you can try to restart the machine to see if the number will disappear. Finally, it may be caused by turning on the notification marking function. You can cancel the lighting of the marking function item in the settings.
