Apple's mobile phone is mute. Did text messages have any sound in the past?

If mute vibration is set, there will be vibration and pop-up prompts in the SMS.

There is a protruding cuboid button above the volume level in the upper left corner of the Apple phone. You can quickly set the mute by adjusting the buttons. If you set the button on the back of the phone, it is mute, otherwise it is standard tone.

At the bottom of the iPhone, there is a speaker on the left and a microphone on the right. There is an extra speaker at the top of the screen as the receiver of the phone. The IPhone 4 also includes a small earpiece for noise cancellation, which is used to reduce the ambient noise during the call. On this basis, the positions of the speaker and the microphone can be exchanged-the speaker is placed on the right. The volume control of all iPhone is on the left, while the volume control of iPod is on the slide button of the application.
