When the Samsung s5830 mobile phone sends a short message, it is not prompted by the system, but has a small yellow icon in the notification bar.

Small yellow icon to see if it is similar to the logo of 360 guards. If it doesn't matter, just help you intercept some malicious news. If not, you can enter 360 Guardian to modify the settings and close the interception system.

If not, you don't have to open it after receiving the text message, and the mobile phone enters the flight mode (for fear of encountering paid software in future operation). Drop down the status bar and click the yellow icon to enter the software to which the icon belongs. If not, you can choose to delete.
