To use location-based services and apps like Google maps on your Galaxy phone, you need to enable your device’s GPS location settings. Your device may use a combination of Wi-Fi, GPS, and mobile networks to determine your location and even get help if your phone is lost or otherwise. Follow the steps below to enable your location services settings.
Step 1. Launch the Settings app, and then select Location.
Step 2. If the switch at the top is Off, turn it On.
Alternatively, you can swipe down on the screen to bring up the Quick panel, and then tap the Location icon to enable or disable location services.
