GPS works best where signals can be received. It requires a direct, open view of the sky in order to communicate with satellites.
The following can result in a lost connection of GPS signals:
- Tall buildings are blocking a direct view of the sky, or there is not a clear view of the sky.
- A storm is causing obstructed views of the satellites.
- There are too many clouds, although this is highly unlikely.
- The GPS settings are not turned on.
- The device's screen has been turned off.
- The device is being held in a manner which blocks the antennas. This is especially true for Galaxy Z Flip models that are folded and closed.
- The phone is set to a Power saving mode. For the best GPS signal, the device should be set to High performance or Optimized.
- The app that uses GPS (like Google Maps) is listed as a sleeping app. You'll need to remove it from the list.
Although the GPS on your device will work inside a building or a house, it is not recommended to use GPS while indoors.
