Sharp 6320C SMS can't be opened, help! ! ! ?

My 9020 sometimes encounters the problem that the mobile phone MMS cannot be downloaded. It doesn't make any difference whether you look at it or not.

Ls said it should be impossible to brush the machine = =

I don't know if the short message (MMS) you said in Lanzhou will disappear after restarting. These will disappear, that is to say, those multimedia messages that have not been downloaded completely. If it is an ordinary text message, there will be problems.
