What happens when you send a text message and click Close?

After receiving the message, click Close, the message will disappear on the push page, and the rest will not be affected.

After clicking Close, your message will not disappear, and there will be bubbles on your message icon. After you click in, you can see the message you just received, or it will show "unread". Read will only be displayed when you click enter and then exit, or read will be displayed when you click "Read All" on the main page of SMS.

If you think SMS push will affect you, look for "Application" in "Settings", then click "SMS" to find "Permission" and cancel "Allow Notification".
