The mobile phone gps gprs is turned off, WIFI can access the Internet, and the weather on WeChat and ink can still be located. With what?

There are usually three kinds of mobile phone positioning:

global positioning system (GPS)

Moving mast

Wifi network or 3g positioning

Obviously, you belong to the latter two. Wechat and ink weather rely on wifi network or 3g positioning.

All you have to do is turn off the internet.

Let me explain something to you:

Whether the Wifi hotspot is encrypted or not, as long as it is turned on, it will send a signal to the surrounding area, which contains the unique identifier in the world: the MAC address.

The mobile phone will send all valid WIFI MAC addresses you collected to the location server. According to these information, the server queries the longitude and latitude coordinates of each hotspot recorded in the database, and calculates according to the signal strength, so as to determine the current position of the mobile phone.
