Cerberus 3.5 is out!

By popular demand, we managed to implement a fake shutdown feature that you can enable in the app settings. When it is enabled, pressing the power button in the lock screen will display a "Power off" popup, that if pressed will show the "Shutting down..." dialog. After a few seconds the screen will switch off and the phone should stay "dead" for about 30 seconds/one minute.

The idea behind this feature is that a thief will immediately try to switch off the phone from the lock screen, see a convincing shutdown sequence and put the phone somewhere (pocket, bag, etc.). Meanwhile, you will still be able to track the phone and send any other command from our website.

We would be glad to get your ideas, suggestions and feedback on how this feature works on your devices. Please contact us via the support form in the app or on the website, or directly at, including the device model and Android version.

New web interface!

We have been working at a responsive redesign of the website, using Material Design and providing a good mobile interface for the web dashboard.

It is still a work in progress, but we are ready to share with you; it can be accessed from this link: . We would be glad to receive feedback, so if you have any thoughts, suggestions, or experience any bugs, please let us know here or via email ( Thanks!

Cerberus 3.3 is out! Here is the changelog:

Changes and bugfixes for Android 6 Marshmallow
Android 6 brought a lot of changes: a new permission model, new API, behavior changes like new power optimizations, and much more. Cerberus is now fully compatible with Marshmallow. For all the features to work, please make sure to enable Cerberus in Settings -> Apps -> Configure apps -> "Draw over other apps", "Modify system settings" and "Battery optimization".

AutoTask: new "Block status bar" and "Delay" actions
You can now create an AutoTask rule that enables or disables the "Block status bar" option, and also there is a new "Delay" action that is useful in rules with multiple actions, to set a delay between one action and the next.

Improved support for phones with a Project Fi SIM card
Project Fi users will now see their phone as a single device on the web dashboard, regardless of the network the phone is connected to. Unfortunately there is still a small issue with the "SIM checker" feature, because both the SIM card serial and IMSI change when the phone switches to a new carrier. If you receive any alerts from SIM checker, please follow the instructions in the Help page on our website to authorize the "new SIM card".

We also added compatibility for multiple Android Wear devices connected with the same phone, and as usual there are other small performance improvements and bugfixes.

You can update to version 3.3 from the Play Store or from our website.

We just published version 3.2 of Cerberus! Here is what's new:

By popular demand, we added a new "Block Status bar" option: enabling it will prevent the status bar to be pulled down in the lock screen. This is useful for devices with Lollipop, since a thief would not be able to modify the quick settings and disconnect the phone from the internet or disable location services, for instance.

We also added dual-SIM support for devices with Android 5.1, since Google introduced official API for dual-SIM in that Android version. Both SIM cards will be protected by the "SIM checker" feature, and you will see the details of each SIM card with the "Get device info" command from the website. BTW, there is an Android OS bug that breaks our alerts if no SIM card is present into the phone (, hopefully Google will fix it in the next update.

There is a new "Bluetooth" condition in AutoTask, so you can create more useful rules, and some performance improvements and small bugfixes.

As usual, you can download the new version from the Play Store or from our website.

Cerberus 3.1 is out! Here are the new features:

Android Wear support
Open the app and go to the "Wearable device" section. As you can see in the attached screenshot, these are the available functionalities:
- Loss prevention: if you forget your phone, your smartwatch will vibrate and display a notification as soon as it disconnects from the phone
- Find device: misplaced the phone and the smartwatch is still connected to it? Say "Start find device" or select the option from the apps on the smartwatch, and your phone will start a loud alarm, so you can find it
- You can also start emergency mode or any rule that you set in AutoTask directly directly from the smartwatch

The "Protect device admin" option is now available also on Android 5.x (Lollipop), so a thief would not be able to disable Cerberus from the Device Administrators.

There are several bug fixes and improvements too. You can download Cerberus 3.1 from the Play Store or from our website.
