Expected Behavior

It is expected that when the GPS is enabled, the onProviderChange event should return true in the GPS field, and when it is disabled, it should return false.

Actual Behavior

When the GPS is disabled on the device and then re-enabled, the onProviderChange event should indicate that the GPS is active (GPS: true). However, instead of receiving true, the event incorrectly reports GPS: false. This incorrect behavior continues until the GPS provider is toggled on and off several times, after which the event finally reflects the correct GPS status.
