In the pop-up location information interface, click Start Location Service, and then select the power saving function below. After turning on the GPS function, go back to the mobile phone desktop, find the settings icon, click Open Settings to enter the settings interface, find more settings options in the interface, and click Open.

After entering the more settings interface, find and enter the following developer options, select the application option of simulated location information, click to open the fake location function, and click Use. Go back to the desktop, find the fake positioning software icon, and click Open. After entering the software interface, you can select the location.

Zoom in on the map, find the required address, click on the selected address, and when a red dot appears, you can click the Start button in the interface to start the simulation. Then open the location to be displayed in the app, and the simulated location will be displayed.

GPS positioning method can be divided into two parts.

1, do not upload positioning; Instead of uploading the information results calculated by the mobile phone itself, the guardian will be notified by SMS, and the calculation results will not be saved by any server.

2. Upload and locate; Uploading and positioning means that the designated mobile phone informs the guardian's mobile phone of the information result calculated by the latitude and longitude of the received GPS satellite coordinates through SMS and uploads it to the server at the same time; The geographical location information stored in the server is kept by the guardian.

Mobile phone positioning system is not necessarily mobile phone GPS positioning. Let's talk about positioning technology first. There are two kinds of positioning technologies, one is based on GPS positioning, and the other is based on mobile operating network base station positioning. The positioning method based on GPS is to use the GPS positioning module on the mobile phone to send its own position signal to the positioning background to realize the positioning of the mobile phone.

Base station positioning is to determine the location of the mobile phone by measuring the distance between the base station and the mobile phone. The latter does not need the mobile phone to have GPS positioning ability, but the accuracy depends largely on the distribution and coverage of base stations, and sometimes the error will exceed one kilometer. The former has higher positioning accuracy. In addition, there are also methods of using Wifi for small-scale positioning.
