How do I know if my mobile phone is being monitored?

Under normal circumstances, it is impossible for others to monitor other people's phones through normal channels, unless it is a public security organ. In a truly high-quality monitoring scheme, the listener cannot judge whether he is being monitored by hearing. It is necessary to record the voice by oscilloscope and other instruments to find the noise (that is, the minimum noise of the receiver who monitors the content), which requires professionals who are familiar with voice coding and decoding in the communication field. In order to combat crimes on communication networks, many countries monitor people's conversations in communication networks, which is a high-quality monitoring scheme. Some methods are of poor quality, but the monitoring effect is acceptable, such as installing spyware on the mobile phone, which can be detected by 360 mobile guards, or running some software to detect the operating system of the mobile phone to check whether there is unknown software running on the mobile phone.

1. Don't give your mobile phone to others for safekeeping.
