Handle enter key in EditText across different devices

Right now I'm handling the enter key in my EditText fields using a an onEditorActionListener and looking at the Action ID for IME_NULL. It works fine for all my users except one. She has an Xperia Arc.

TextView.OnEditorActionListener keyListener = new TextView.OnEditorActionListener(){
  public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
    if(actionId == EditorInfo.IME_NULL){
      if(((EditText)findViewById(view.getId())) == ((EditText)findViewById(R.id.etUser))){
        ((EditText) findViewById(R.id.etPass)).requestFocus();
      }
      if(((EditText)findViewById(view.getId())) == ((EditText)findViewById(R.id.etPass))){
        logon();
      }
    }
  return true;
  }
};

After learning about the issue, I tried another approach by using an onKeyListener and looking for the key event ACTION_DOWN then checking the keycode if it matched KEYCODE_ENTER.

EditText etUserName = (EditText) findViewById(R.id.etUser);
etUserName.setOnKeyListener(new OnKeyListener() {
  public boolean onKey(View view, int keyCode, KeyEvent event){
    if (event.getAction() == KeyEvent.ACTION_DOWN){
      switch (keyCode)
      {
        case KeyEvent.KEYCODE_DPAD_CENTER:
        case KeyEvent.KEYCODE_ENTER:
          if(((EditText)findViewById(view.getId())) == ((EditText)findViewById(R.id.etUser))){
            ((EditText) findViewById(R.id.etPass)).requestFocus();
          }
          return true;
        default:
          break;
      }
    }
    return false;
  }
});

No dice on that either. I'm at a loss right now. There are plenty of apps out there that handle the enter key just fine. what are they doing differently?
