Nut mobile phone has a ringtone, but the SMS prompt has no sound.

Hello, I have encountered the same problem. After consulting customer service, let me uninstall 360 and other software first. If not, I will restore the factory settings. Before restoring the factory settings, I should back up all the information and important information of my mobile phone. You can try these two methods first, because you don't know what caused your situation. I tried these two methods at that time, but they didn't work. Then I had to go to the after-sales service center. Finally, there was a hardware problem. The microphone of the mobile phone was broken, and then I replaced it with another one and it returned to normal. If the above two methods fail, you can go to official website to inquire about the nearby after-sales maintenance points. If it's far away, you can mail it. If it's near, you can go directly, and it will be repaired quickly. Just a moment. And if you just bought it, you can return it soon. Even if it can't be returned, the first maintenance is free.
