Apple's mobile phone keeps displaying unread text messages, but it can't be found. What should I do?

Maybe the inbox is full. Check whether there is a message on the SIM card, which may be a missed call reminder. Another possibility is that you have installed any security software (such as 360) to intercept messages.

See if it exists. Pull down the screen top curtain and click "Clear". Restarting the phone after exiting can eliminate the "developer option" (high success rate). Do not select the active. Turn off the phone and restart it.

Settings-Application Manager-All Information-Clear Data.

Look at the number of unread messages: drop down the notification bar and delete all messages to see if they can be deleted.

Settings-Application Manager-All-Select BadgeProvider, click Clear Data, and then write it down. Write down the number of the message, for example, 10086. After saving 10086, send a message (or send a message directly) to view and extract the information. Have a conversation with 10086.
