Why icon don't appear on Android Galaxy S6 and S7?

I have a problem without logic, my application run smoothly on almost all devices but when I try the Samsung Galaxy S6 and S7 models, simply icon does not appear anywhere.
I've tried to send the official store (still the same)
If I run via simulator the application opens, but without the icon (shortcut).
My AndroidManifest.xml

Intent ACTION_CALL is not being intercepted by my application

There's an application with a button that when pressed is using the startActivity method with the ACTION_CALL intent.
This is how its called:
public void call(String number)
{
Intent myIntent = new Intent(Intent.ACTION_CALL);
myIntent.setData(Uri.parse("tel:" + number);
startActivity(myIntent);
}
I have made a dialer app with the permission:
<uses-permission android:name="android.permission.CALL_PHONE" />
And my manifest looks like this:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="tel" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Every other question I've seen is suggesting this exact declarations to be made in the manifest.
I've checked and there are no defaults set on the Google dialer app which comes with the phone.
So why won't a pop up dialog show with an option to choose my application as the dialer to catch that intent?

I have finally got it to work.
After adding a bunch of intent filters it started working:
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
<action android:name="android.intent.action.CALL" />
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
<intent-filter android:priority="100" >
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.CALL_PRIVILEGED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="tel" />
</intent-filter>
I think the first one did the magic.

put this as intent filter of your activity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<action android:name="android.intent.action.CALL_BUTTON" />
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="tel" />
</intent-filter>

Using implicit intent to launch activity?

I have a problem using implicit intent to launch activity within my application.
I have created activities RecordList (lists all the albums), RecordEditor (used to add/edit tracks of record) and TrackEditor. I've managed to get the RecordEditor to launch when user selects new or edit from the RecordList. Problem occurs when I try to add new track to the the record (launch the TrackEditor activity).
Here is how I have defined the activities in manifest:
RecordList
<activity android:name="RecordList">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.EDIT" />
<action android:name="android.intent.action.PICK" />
<data android:mimeType="vnd.android.cursor.item/vnd.example.record" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.GET_CONTENT" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.item/vnd.example.record" />
</intent-filter>
</activity>
RecordEditor
<intent-filter>
<action android:name="android.intent.action.GET_CONTENT" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.item/vnd.example.track" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.EDIT" />
<action android:name="com.example.records.action.EDIT_RECORD" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.item/vnd.example.record" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.INSERT" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.dir/vnd.example.record" />
</intent-filter>
TrackEditor
<activity android:name="TrackEditor">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.EDIT" />
<action android:name="com.example.records.action.EDIT_TRACK" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.item/vnd.example.track" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.INSERT" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.dir/vnd.example.track" />
</intent-filter>
</activity>
And here is the exception I keep getting when trying to add new track to Record:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.INSERT dat=content://com.example.provider.Track/tracks }
I've used the NotePad example as base for this but I am unable to figure out where I am doing wrong. Any help would be appreciated. :)

It is unclear what you think you are gaining from these "implicit Intents".
That being said, your problem is with your content provider. It is not indicating that the MIME type for content://com.example.provider.Track/tracks is any of those for which you support the INSERT action.
