What if there is no sound or prompt when I receive a text message?

I have used my 30 for more than a month, and I like her more and more. But recently, there has been no short message prompt, no bell, no reminder. I can only determine whether there is a short message by looking at whether the function key in the middle flashes. It was so depressing for a while.

During this period, I uninstalled 360 mobile guards, no; Try security guards to uninstall, not yet!

Today, I am determined to solve this problem. I found that I can have a prompt when I start my mobile phone, but it will soon disappear. This shows that there is a program that conflicts with my SMS prompt. Then I installed the mobile phone guard, checked the running programs through the mobile phone guard, then closed one, tried to send SMS, and then closed the other, tried to send SMS, and the result really made me try. There is a program, as long as you close it, you can get a message prompt and uninstall it quickly. As a result, the problem has been solved. Let me share it with you here. The plan is:
