Broadcast Receiver not being invoked in Headless JS (Native Module in React Native)

I've written a native android module in React Native that consists of a broadcast receiver to listen to ACTION_SCREEN_OFF, ACTION_SCREEN_ON and ACTION_USER_PRESENT. I've created a headless service that is called by the receiver which executes the JS code, but the receiver is not being triggered to begin with.

phoneScreenOnOffModule.java:

package com.tracker;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.bridge.ReactContextBaseJavaModule;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.ReactMethod;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.util.Log;
import java.util.Map;
import java.util.HashMap;

public class phoneScreenOnOffModule extends ReactContextBaseJavaModule {

   private ReactApplicationContext reactContext;

   phoneScreenOnOffModule(ReactApplicationContext context) {
       super(context);
       reactContext=context;
       registerBroadcastReceiver();
   }

   @Override
   public String getName() {
       return "phoneScreenOnOffModule";
   }

   private final BroadcastReceiver phoneScreenReceiver = new BroadcastReceiver() {
       @Override
       public void onReceive(Context context, Intent intent) {
           if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
                Log.d("StackOverflow", "screen_off");
            } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
                Log.d("StackOverflow", "screen_on");
            } else if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
                Log.d("StackOverflow", "user_present");
            }
            Intent serviceIntent = new Intent(context, phoneScreenService.class);
            context.startService(serviceIntent);
            HeadlessJsTaskService.acquireWakeLockNow(context);
       }
   };

   private void registerBroadcastReceiver() {
       IntentFilter filter = new IntentFilter();
       filter.addAction(Intent.ACTION_SCREEN_OFF);
       filter.addAction(Intent.ACTION_SCREEN_ON);
       filter.addAction(Intent.ACTION_USER_PRESENT);
       reactContext.registerReceiver(phoneScreenReceiver, filter);
   }   
}

phoneScreenService.java:

package com.tracker;
import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
import javax.annotation.Nullable;

public class phoneScreenService extends HeadlessJsTaskService {

  @Override
  protected @Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {
    Bundle extras = intent.getExtras();
    if (extras != null) {
      return new HeadlessJsTaskConfig(
          "phoneScreen",
          Arguments.fromBundle(extras),
          5000, // timeout for the task
          true // optional: defines whether or not  the task is allowed in foreground. Default is false
        );
    }
    return null;
  }
}

Manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.tracker">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:name=".MainApplication"

        </intent-filter>
      </activity>
    </application>
</manifest>

Relevant JS code:

import { AppRegistry } from 'react-native';

const phoneScreen = async (data) => {
  console.log("works", data);
}
AppRegistry.registerHeadlessTask('phoneScreen', () => phoneScreen);
