The app description says that Cerberus works, even without internet connection but when I turn off my Wi-Fi & 3G and try to use some of the functions on the website from my laptop, it says: Problem communicating with your device. Also, I always have to log back in after I hide and show the app in the app drawer. My Galaxy Nexus is rooted and I'm currently running Jelly Bean. Anyone know why I can't use any of Cerberus's functions without an active internet connection?
