Please try the following:
1. Check the GPS signal: if you're indoors or around tall buildings, move outdoors or to an open space for better GPS signal.
2. Update data: make sure that your phone is updated with the latest map data and ensure yoy have a stable network connection.
3. Turn on the location service: make sure your phone has the location service turned on and ensure it's enabled.
4. Restart the phone to rule out any software problems.
5. Get the hardware checked out: if the positioning function fails for a long time, it may be caused by a hardware failure and you'll need to have it professionally inspected and repaired.
If the problem persists, please contact the Nothing support team for further assistance
