What is the reason why Apple 6 has no voice information?

Reason 1: Let's turn on the phone and see if there is a moon in the upper right corner of the phone. If yes, it has been transferred to do not disturb mode. We turned on the settings and found that after the Do Not Disturb mode entered the Do Not Disturb mode, let's see if this was turned on manually. If do not disturb mode is turned on, when the screen is locked, other people's calls will become silent, so we can't hear the bell. At this time, all we have to do is close do not disturb mode.

Reason 2: First, we turn on the phone, turn on the settings, and then look for the sound. After turning on the sound settings, we can see that there is a scroll bar, which is the scroll bar of sound size. Let's see if this scroll bar is at the far left. If so, it's because we turned the sound down to the minimum, so there is no sound.

Reason 3: There is a button on the left side of Apple's 6s mobile phone. As shown in the figure, above the sound volume button, this button is the mute button. If you press it, there will be no sound. If you don't know whether pressing this key will cause mute, then pressing it once will bring up the icon as shown in the figure, that is, the mute icon, indicating that there was no mute before, and then press it back.

Reason 4: There is also a button on the right side of the fuselage. If you press this button, it will become silent. If you press this button twice, it will become silent. Of course there won't be a bell. Of course, it was an accident.
