The plus sign of my mobile phone information is below, how can I turn it to the top?

Glad to answer your question, dear? Open the SMS on your mobile phone, you can search for information on it, and the plus sign below can create new information. Click More Settings on the right side of the plus sign to enter the setting SMS interface. There are common and other function settings here. Opening the unread top can display unread messages. Click cancel sending, and double-click the bubble box of session information within 6 seconds to cancel sending. In other functions, click Send Report and select the sending method, so that every time the message is sent successfully, there will be a report message prompt.
