Quick Fixes:

• Toggle it Off/On: The simplest solution. Swipe down for notifications, tap the location/GPS icon to disable it for a few seconds, then re-enable. This refreshes the connection.
• Check Location Settings: Ensure "Location" is on in your phone's settings. Check individual app permissions too - make sure the app you're using has access to your location.
• Upgrade Apps & System: Outdated software can cause glitches. Update your Maps app and any other navigation apps you use. Check for system updates on your phone too.

Deeper Dives:

• Improve Signal: GPS needs a clear view of the sky. Go outdoors or near a window. Avoid thick cases or signal-blocking materials.
• Calibrate Compass: Some phones have a built-in magnetometer, used for calibration. Find the "Compass" app and follow the on-screen calibration instructions.
• Clear App Cache: A corrupted app cache can mess with GPS. Go to Settings > Apps, find your Maps app, and tap "Clear Cache". Restart your phone and try again.

Advanced Fixes:

• Reset Network Settings: This resets Wi-Fi, Bluetooth, and mobile data settings. Go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. Remember to reconnect to your Wi-Fi network afterward.
• Factory Reset: A last resort. Back up your data first! Go to Settings > System > Reset options > Factory data reset. This wipes your phone clean, so use it only if other options fail.
• Bonus Tip: If your GPS issue persists, contact your phone manufacturer's support team for specific troubleshooting steps.
