Am I correct in thinking that when you use Nova as your launcher, you then lose the icon number indicators for the number of calls received, emails received, calls received, etc?
Well, if you mean lose them as you still don't have them (or maybe you do on some other launcher) then yes, but you can get them by purchasing the full version.
There is a setting in Nova Launcher Prime that will allow you to use it. However, you need to get another app in order to get it to work. The app is free and if you try and enable the option in Nova Launcher Prime, it will easily take you to which app you should download.
That's great to know, installed now. Thanks guys. I bought Nova Prime a couple of years ago but never really used it until recently, where I have gotten rid of TouchWiz in preference for Nova. It gives me a more Nexus 4 experience that I prefer. Now if only I could get rid of that awful bloop sound! I had a lovely quiet blip noise on my Nexus 4.
It actually still works. In Tesla unread settings, scroll down and tick the box for Notification Bar Watcher and Select Apps where you would select Hangouts.
