There are updates, and then there are updates. For Cerberus, version 3.0 is the latter. It gets the app ready for Android 5.0 by covering it with pretty materials. Well, as pretty as this particularly unflattering app is going to get.
Cerberus still consists mostly of menus, but now the action bar is very red, a hamburger icon sits in the top left corner, and a sidebar (redesigned since the last time we took a look at the beta) now pulls out over every other part of the interface.
Some of the new features include the ability to prevent powering down from the lockscreen and an option to block USB debugging on your device. Other additions have surfaced since Cerberus first announced the beta, such as commands to remotely enable/disable a Wi-Fi hostpot. You can also record up to 30 seconds of screen activity and have the clip sent to you via email. Note, this is just scratching the surface.
Sadly, the release isn't without its losses. The option to protect the Device Administrators page has been removed from the app if you're running Lollipop, as the developers weren't able to work out all the kinks.
Cerberus works on devices running Android 4.0 and higher, but if you're on 4.4, make sure you're not using ART, as it and Cerberus don't get along.
