I turn it off to save battery life. Open kindle to read and kindle locks up after a short while. I then notice that the wifi is now turned on and about 30 apps are now on draining power and memory. I close out everything, sometimes reboot, turn off wifi, rinse and repeat. Same thing. Can someone help me figure out what app(s) may be turning my wifi on when I don't want it? Using LG Spirit 4G, Android 4.0.4 with MetroPCS. Could it have something to do with Metro's new easywifi app?
