Apple's thirteen-year message flashed but there was no sound.

There is a mute button on the left side of the front of Apple's mobile phone, which will turn on the mute mode downward and turn off the mute mode upward to make the message sound. It is also possible that the do not disturb mode is turned on by the mobile phone, so that the incoming call information can be muted within a set time, which can be turned off in the settings.

In addition, check whether the mobile phone has turned on message notification, go to "Settings" of the mobile phone, click "Notification", click to enter the application that needs to receive messages in the list, turn on "Allow notification" and turn on the switch behind "Sound".

IPhone 13 is the biggest design change of Apple's terminal products since the iPhone, and bangs have been successfully reduced by 20% by moving the receiver up. The back dual-lens adopts diagonal design, which reserves more space for the battery, and performs better than the previous generation iPhone 12 in product recognition and aesthetics.
