Geolocation timed out, code 3 #15718

my code is
navigator.geolocation.getCurrentPosition(
position => {
console.log(position)
},
error => {
console.log(error)
},
{
enableHighAccuracy: Platform.OS !== 'android',
timeout: 20000
}
)
Before when I open the device's position
the result is code:1 message: "No location provider available."
After when I open the device's position
the result is code:3 message: "Location request timed out"
