Default Phone App Intent Action DIAL not opening activity

Question

I am developing a default Phone App for android like :

Having permissions listed in manifest and requested runtime too :

<uses-permission android:name="android.permission.CALL_PHONE" /> 
<uses-permission android:name="android.permission.READ_CONTACTS" /> 
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" /> 
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /> 
<uses-permission android:name="android.permission.ACTION_MANAGE_OVERLAY_PERMISSION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

Before requesting these permissions i have requested for the granting it as default via ACTION_CHANGE_DEFAULT_DIALER intent first then permissions and then ACTION_MANAGE_OVERLAY_PERMISSION settings opened up for the user to switch it ON.

In My manifest.xml i have declared the service InCallService implementation:

<service
        android:name=".InCallServiceImplementation"
        android:enabled="true"
        android:exported="true"
        android:permission="android.permission.BIND_INCALL_SERVICE">
        <meta-data
            android:name="android.telecom.IN_CALL_SERVICE_UI"
            android:value="true" />
        <meta-data
            android:name="android.telecom.IN_CALL_SERVICE_RINGING"
            android:value="true" />

        <intent-filter>
            <action android:name="android.telecom.InCallService" />
        </intent-filter>
    </service>

and

Activity which opens my apps dial pad when user initiates android.intent.action.DIAL :

<activity
        android:name=".DialerActivity"
        android:label="@string/title_activity_dialer"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>

            <!-- Handle links from other applications -->
            <action android:name="android.intent.action.VIEW" />
            <action android:name="android.intent.action.DIAL" />
            <action android:name="android.intent.action.CALL" />

            <!-- Populate the system chooser -->
            <category android:name="android.intent.category.DEFAULT" />

            <!-- Handle links in browsers -->
            <category android:name="android.intent.category.BROWSABLE" />

            <data android:scheme="tel" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.DIAL" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

and my DialerActivity.java :

@Override
protected void onCreate(Bundle savedInstanceState)
{
     if (getIntent() != null && getIntent().getData() != null)
    {
        Log.d("MainActivity URI :", getIntent().getData().getSchemeSpecificPart());
    }
    else
    {
        Log.d("MainActivity URI :", "NULL INTENT FOUND");
    }
}

1. My InCallServiceImplementation getting invoked when user initiates android.intent.action.CALL from calling button
2. But when user touches the phone number in recent calls within company provided phone app, which i think is a android.intent.action.DIAL and it should open my DialerActivity, but its not happening neither on emulator, nor on real device..

for your reference you can see i am printing getSchemeSpecificPart in my DialerActivity onCreate which never gets called.. Why it is not opening the dialer activity? I would like to thank you in advance.
