Getting different instances while resolving from container

I have a specific platform service which is being registered using a platform initializer

 public class AndroidInitializer : IPlatformInitializer
    {
        public void RegisterTypes(IContainerRegistry containerRegistry)
        {
            containerRegistry.RegisterInstance<IBlueToothService>(new BlueToothService_Android());
        }
    }

As you see I am registering an instance as I want it to be the same instance.
My main page VM get this service injected in its constructor:

public MainPageViewModel(INavigationService navigationService, IBlueToothService btService)
           : base(navigationService)
        {
             RefreshBlueTooothDevicesCommand = new DelegateCommand(RefreshBlueToothExecuted, RefreshBlueToothCanExecute);
            _blueToothService = btService;
            _blueToothService.DeviceAdded += BlueToothServiceDeviceAdded;
            _blueToothService.ScanFinished += () => ToggleRunningState();
        }

I am using this service also in a broadcast receiver:

 public override void OnReceive(Context context, Intent intent)
        {            
           IBlueToothService service = Xamarin.Forms.DependencyService.Get<IBlueToothService>();
            string action = intent.Action;
            if (action == BluetoothDevice.ActionFound)
            {
                BluetoothDevice newDevice = (BluetoothDevice)intent.GetParcelableExtra(BluetoothDevice.ExtraDevice);
                service.AddDevice(new Models.BluetoothDevice(newDevice.Name, newDevice.Address));
            }
            if(action == BluetoothAdapter.ActionDiscoveryFinished)
            {
                service.RaiseScanFinishedEvent();
            }
        }

I am not getting the same instance. but 2 different ones. I am pretty sure that each one of them resolves them from a different container but I cant figure our how to point all of them to the same one.

Thanks.
