Android Nougat 7.1.1 broadcastReceiver don't receive the action WifiManager.SCAN_RESULTS_AVAILABLE_ACTION

i am working on Nexus 5X android Nougat 7.1.1 on BroadCastReceiver with action WifiManager.SCAN_RESULTS_AVAILABLE_ACTION defined in AndroidManifests.xml, but is don't work properly, is works only when i opened the wifi settings page.

Note: Since i have updated the device version from 7.0.0 to 7.1.1 this happening with me , before that, everything was working properly.

WiifiBroadcastReceiver.java

public class WifiBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        String action = intent.getAction();

        if(action.equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) {
            List<ScanResult> wifiScanResult = new ArrayList<>();
            WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
            if (wifiManager.isWifiEnabled()) {
               wifiScanResult = wifiManager.getScanResults();
            }
        }
    }
}

AndroidManifests.xml

It's the system error of the android 7.1.1.

Some devices have been updated to Android 7.1.2 where this error was fixed, another ones now have rollback to the previous version.
