Android - Tablayout in arrivo su Samsung Galaxy Tab 10.1

Question

Sto usando un tablayout nidificato all'interno di una finestra di dialogo che utilizzo per un menu nella mia app. Funziona bene su tutti gli altri dispositivi tranne il Galaxy Tab 10.1 su cui viene appena vuoto. Non c'è un singolo errore, avvertimento o menzione di tale nel logcat o ovunque e non vedo nulla che venga nullo quando provo a debug. Qualcuno ha qualche idea su quale potrebbe essere il problema con questo dispositivo specifico e un tablayout nidificato in una finestra di dialogo? Dovrei semplicemente spostare l'intero menu Tablayout nella propria attività/subattività?

Ecco quello che sto facendo con il codice ..... non è niente di pazzo:

dialog.setContentView(R.layout.maintabmenu);
final TabHost tabs = (TabHost) dialog.findViewById(R.id.my_tabhost);
tabs.setup();
tabs.setCurrentTab(0);
TabSpec tspec11 = tabs.newTabSpec("New Tab");
    tspec11.setIndicator("User");

tspec11.setContent(R.id.ScrollView01);
tabs.addTab(tspec11);

TabSpec tspec2 = tabs.newTabSpec("New Tab");
tspec2.setIndicator("Settings");

tspec2.setContent(R.id.ScrollView02);
tabs.addTab(tspec2);

TabSpec tspec3 = tabs.newTabSpec("New Tab");
tspec3.setIndicator("My options");
tspec3.setContent(R.id.ScrollView03);
tabs.addTab(tspec3);                 

ed ecco l'XML:
