Problems with TTS on Samsung Galaxy S3

Question

I'm developing an app for android that uses TTS. I've created a splash screen where I check if the TTS engine is installed and in case that is not installed, it goes to Google Play to download it.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
...
    Intent checkIntent = new Intent();
    checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
    startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
...
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
...
    if (requestCode == PersonalTextToSpeech.MY_DATA_CHECK_CODE)
    {
        if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
        {
            mTts = new TextToSpeech(context, this);
        } else
        {
            Intent installIntent = new Intent();
            installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            context.startActivity(installIntent);
        }
    }
}

It was working fine in Samsung devices with 2.2 and 2.3.x OS. It goes to Google Play if needed, but now I've tried with a Samsung Galaxy S3 (with 4.1.1), which has 2 TTS installed by default (Samsung and Google), so I get a dialog asking to select one.

If the user selects Samsung it works perfect, but if the user selects Google, it goes to Settings --> Language and input --> Text-to-speech output --> Google Text-to-speech Engine --> Settings --> Install Voice Data and I get this:

So, I have 3 questions/problems:

1. Is there any way to force programatically to use Samsung TTS without asking?
   
   
2. My device is from Spain, but if I change the language to English, this one is not available in my Google list of TTS languages, and I can't find a way to add it (see screenshot #2).
   
   
3. If I change the language to spanish, this language is supposed to be installed in my device (see screenshot #2), but for some reason TTS resultCode is LANG_NOT_SUPPORTED (-2).
   
   

In fact, right now while I write this, I've just found something weird.

If you select Samsung TTS, it will "work" (resultCode = CHECK_VOICE_DATA_PASS (1)), but the "voice sound" will change depending on how you have your setting (view Screenshot #3):

If you choose Samsung, it will use Samsung TTS or Google TTS according to what you have selected in: Settings --> Language and input --> Text-to-speech output.

So, even if you select Samsung TTS, you could be using Google TTS, but if you select Google TTS directly (see Screenshot #1) it will fail.

Can someone explain me what I'm doing wrong?

Thanks for your help.

i too stucked in this problem and i solved it by just replacing a code in my onActivityResult. Instead of checking for TTS Data,i just checked for available voices.

             if (availableLanguages.isEmpty()) {
                // no language data available, prompt for install
                Intent installIntent = new Intent();
                installIntent
                        .setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(installIntent);
            } else {
                // some language data is available, create TTS instance
                myTTS = new TextToSpeech(this, this);
            }
