Why does the mobile phone always have message voice, but can't see the message?

There must be some software installed, and then the information port was blocked, and the mobile phone appeared, but the problem could not be found, and then it crashed. If you have a call, or you believe in Anyi, there is still 360. You can try to delete these softwares and see if you can receive text messages. That's all we can do at present. You can also back them up and check the machine!
