What is the mobile phone factory mode used for?

The role of mobile phone factory mode:

1. Analyze the reception signal condition. We often encounter two mobile phones of the same brand and different models or two mobile phones of different brands. When the mobile phone is in the same place, the signal strength display is different. Some users think that the number of cells is not important, as long as they can make and receive calls normally. Yes, it is inaccurate to judge the sending and receiving quality of a mobile phone based solely on the number of bars of the signal, but if you turn on the engineering mode of the mobile phone, the status of the received signal will be displayed from the number of bars to a numerical value, and there is no way to hide the strength of the reception. At present, Motorola, Nokia, and Ericsson can enable engineering mode relatively easily.

2. We can know the base station number. In addition to the base station ID that will be used when reflecting the reception status as mentioned above, if the base station accidentally "hangs up", you can notify the network operator to send someone to deal with it.

If users who turn on the mobile phone engineering mode see that nearby base stations are far away from their regular activities, the signal is not strong, and the call quality is poor, they can report it to the customer service department. Go and help them improve their network.

4. To avoid network traffic jams, mobile phones generally choose the nearest and strongest base station to register and stay on this channel. Mobile phones that can turn on engineering mode and have frequency locking functions will be used when you When the phone is jammed, you can use the frequency lock function to force the phone to register with other base stations and use it, which can avoid the pain of channel "traffic jam".
