Holo Launcher Plus, Apex Launcher, Nova Launcher Plus; none of these display a little number on my Text Messaging Icon when I receive an MMS. When I receive SMS, it's fine. But MMS only shows up in the notification bar.
However, the stock launcher updates the count on the icon. Stock launcher problem for me is that it doesn't show a Gmail count on the icon.
Is there some trick to getting the count to update for MMS messages?
