The SMS icon on the desktop of Samsung i9300 always shows unread messages.

Is your mobile phone equipped with QQ mobile phone housekeeper or 360 mobile phone housekeeper and some software? Because many short messages will be automatically intercepted as spam messages by these softwares, there will be unread short messages on your icon, but there is no new information in your short messages, which is why I found them. What I hate most is that short number messages are sent to me, which automatically defaults to spam messages. Later, I uninstalled the software. . . . Hehe, remember to give me extra points! !
