What is the reason for inaccurate mobile phone positioning and how to solve it

First of all, we need to know the principles and methods of positioning. Generally, our mobile phones use mobile network positioning, which is to calculate the location information of the mobile phone by connecting to the base station signal. The accuracy is slightly lower than GPS positioning. The most common reason for inaccurate mobile phone positioning is the surrounding environment. In a remote, closed and narrow space environment, it is difficult for mobile phone signals to cover, and the positioning will naturally be inaccurate, causing the mobile phone navigation to lose its function.

If the signal is interfered with, the positioning of the mobile phone will also be inaccurate. For example, the refraction effect of the atmosphere on electromagnetic waves and the blocking of metal objects may interfere with the mobile phone signal. In addition, heavy metal mobile phone cases will also interfere with the signal and affect positioning.

The coordinate system standard of the map is generally WSG-84, while that of my country is GCJ-02. These two standards need to be converted during positioning. If there is a difference during the conversion process, it may also cause positioning deviation.

So how to solve it?

1. Use multiple positioning methods; turn on the phone's GPS, mobile network, WiFi, and Bluetooth functions at the same time, allowing the phone to complement each other in multiple ways to achieve accurate positioning.

2. Check the location permission of the APP; if the phone still cannot be located, it is possible that the location permission of the APP is turned off. You can check whether the location permission of the APP is turned on in [Settings] - [Location Service].

3. Reset the location information switch; if the above three methods do not work, you can turn off and then turn on the location information switch in the phone's settings to allow the phone to reposition itself.

4. Turn on the high-accuracy positioning mode on your Android phone; outdoors, give priority to the high-accuracy positioning mode, which can greatly improve the accuracy of positioning.
