What causes phone GPS not working accurately?

My phone GPS not working properly has been causing issues with navigation apps. It shows my location incorrectly or loses signal frequently, especially in cities with tall buildings. What causes phone GPS not working accurately? Are there calibration methods or settings that can improve GPS performance?

Phone GPS not working accurately in cities is common due to signal reflection off buildings. This is called urban canyon effect. Try going to an open area to see if accuracy improves. Also, make sure location services are set to high accuracy mode.

Try downloading offline maps for your area. This can help with phone GPS not working issues because the app can use cell tower and Wi-Fi positioning to supplement GPS when signal is weak. Google Maps and other navigation apps have this feature.

There are GPS calibration apps that can help with phone GPS not working accurately. They walk you through figure-eight motions to calibrate the compass and improve accuracy. Also, make sure your phone case isn't interfering with GPS signal.
