What kind of Menu button? The one that is displayed on the Action bar or digital buttons below? Because it might not be displayed because the phone might have a dedicated, physical menu button. As from the Android docs:
The action overflow in the action bar provides access to your app's less frequently used actions. The overflow icon only appears on phones that have no menu hardware keys. Phones with menu keys display the action overflow when the user presses the key.
