How is it that the phone always hangs up automatically when talking?

There are several reasons for automatically hanging up when making a phone call:

1, cell phone signal is poor. When making a phone call, any party in the call is in the area with poor signal, which will easily lead to the automatic hang-up of the phone without signal;

2. The mobile phone battery is insufficient. The mobile phone may not be able to receive electromagnetic waves normally due to insufficient power, resulting in the interruption of the mobile phone signal;

3. Illegal operation of mobile phone software leads to signal interruption. Individual software was not developed in accordance with the relevant provisions of the state when it was designed. When this kind of software is running, some operations, such as accessing mobile data, are enforced, which leads to the destruction of call priority and eventually leads to call interruption.

4. The mobile phone receives the radio interference interrupt signal. When the mobile phone is in a strong magnetic field, the signal will be greatly disturbed, which will cause the signal interruption of the mobile phone in serious cases;

5. During the call, the other party accidentally pressed the "Stop Call" button, resulting in the call being terminated.

How cell phone calls work:

Telephone communication is a communication technology that uses electricity as the medium and transmits language through the mutual conversion of acoustic energy and electric energy.

The specific process is as follows:

1. The simplest way for two users to communicate is to connect two phones with a pair of wires.

2. When the speaker picks up the phone and speaks into the microphone, the vibration of the vocal cords excites the air to vibrate, forming sound waves.

3. Sound waves act on the microphone to generate current, which is called voice current.

4. Voice current is transmitted to the receiver of the other party's phone along the line.

5, and the receiver is just the opposite of a microphone-it converts the current into sound waves and transmits them to people's ears through the air. In this way, the simplest call process is completed.
