The thing is that most IP addresses already exist in database and are assigned with approximate location in Google and other search engines. Google may wrongly detect your location and provide you with search results that are meant for someone from another city or country.

There are a few possible reasons why Google Maps might have shown your location in the incorrect place. Your location settings may be incorrect. Make sure that your location services are turned on and that you are giving Google Maps permission to access your location. You can also try restarting your device.

The first thing you can try is resetting the GPS on your phone, which will increase the accuracy of your GPS and thus fix the issue of Google Maps showing you the wrong location. You may just need to swipe down the quick-setting panel to turn off and on GPS again on Android phone.
