If your device shows a “GPS Signal Not Found” error, check if location services are enabled. On Android, go to “Settings” > “Location” and toggle it on. On iPhone, go to “Settings” > “Privacy” > “Location Services” and enable it. Ensure the app has the necessary location permissions. Restart your phone and try using GPS again. If the problem persists, toggle airplane mode on and off to reset connections. Moving to an open area with a clear sky can improve GPS accuracy, as buildings and obstructions may block satellite signals, causing weak or lost GPS connections.
