I just bought the Nexus 4, and when I receive a SMS, there is no like "1" or "2" on the message icon. Can I make that appear? Also, I don't receive notification on the screen. It just ring. Can I receive a notification just like the iphone does? Thanks
That will get icons working for all your Apps, not just SMS.
If you want popups, there are several options.
Personally I use NotifierPro--> https://play.google.com/store/apps/de...
But that Dev has lots of Notification Apps so you should check out some of the free versions to see which best suits your needs.
