This is my first smart phone and I've only had it for a few days; so far I love it, but I do have an issue I haven't been able to solve. When I turn off the mobile data connection via the Settings > Battery & data manager > Data delivery > Data enabled option it turns itself back on the next time I unlock my screen. I installed the 'Data Enabler Widget' and the same thing happened. I've checked or unchecked, as appropriate, every option that would seem to have anything to do with this and no dice. I want a simple way to control whether or not my phone is downloading data over the mobile network. Any suggestions?
