Hey y'all, I wonder if someone can help me with this. I have a Galaxy S2, more specifically the T-Mobile T989 model, which is known in my country as the Galaxy S2 Plus. It has Android 4.1 Jelly Bean installed and I wonder if I can change the quick settings? I want to add a quick setting to activate/deactivate mobile data since it doesn't appear, but it does in other Galaxy phones with the same Android version. I've explored all the settings in my phone and there's no option, so I'm guessing it's not possible in this version of Android, but is there any kind of trick to do this? Please let me know if there is one, 'cause it would be a very useful feature.
