How to set the limit of mobile phone calls? My phone always hangs up automatically.

1. The cell phone signal is very poor. Especially in the process of making a phone call, when one of the two communication parties is in the signal blind area, the mobile phone will automatically hang up because there is no signal. In this case, you should go to a place with strong information to make a phone call and answer the phone.

2. The mobile phone battery is insufficient. Some mobile phones can't receive electromagnetic waves normally because of insufficient power, which leads to the interruption of mobile phone signals. Therefore, once the mobile phone is found to be low in power, it should be charged in time.

3. The illegal operation of some mobile phone software leads to signal interruption. Because some software was not developed in accordance with the relevant national regulations when it was designed, some operations such as accessing mobile data were forced when it was running, which led to the destruction of the call priority and eventually led to the interruption of the call. Therefore, try not to install mobile phone software of unknown origin. If necessary, you can download the application from the reputable Android market or other well-known websites.

4. Cell phone signal is interrupted due to electromagnetic interference. When making a phone call, the mobile phone is under a strong magnetic field. At this time, the mobile phone signal is greatly disturbed, and the mobile phone signal is interrupted in severe cases. The solution is to stay away from the strong magnetic field as much as possible and then make a phone call.

5. Human factors lead to the interruption of mobile phone calls. During the call, the other party accidentally pressed the "Stop Call" button, which caused the call to stop. In this case, you can call normally after dialing several times.
