If you took advantage of the free account activation (mentioned on the O-Deck by bangishotyou here) or already had it and installed the app update you may have noticed something called "Radar Mode" under the What's new section of the app description.

But there hasn't been much mentioned about how it works. There was a comment on the Android Police article about the sale saying radar mode was only available to new users, which I'm happy to say isn't true. The article itself mentions that it "toggles the hotspot on for the lost device, then uses the signal strength to guide you in the right direction." It actually toggles the hotspot on the device you're using to find the one that's lost. And after checking the Cerberus forums, I found out you need the Client Cerberus app to make use of it. So if, hypothetically you've lost your phone, and are using someone else's, install this app on their phone.


So, with both the main Cerberus Anti-Theft app and Client app installed, you're ready to go (here come the pictures).

First you'll get the menu (1):


From there, select Web control, and you'll be asked to log in (2). You should be logging into the account of the lost device you're searching for.


If you log into the account for the device you're holding, and it's the default device that gets listed, it'll tell you as much (3).


Switch to the device you're looking for (in this case I'm using my Nexus 7 as the "lost device"). Once it narrows down the search so that it must be in the same building (in this case, my apartment), the radar option (marked in green in the image) will become selectable (4).


Then you'll get a prompt that WiFi needs to be disabled, which means this will only work on a device that also has a data plan (5).


After that, you'll get a notice that radar mode is starting (6)


After you hit ok, the hotspot on the phone you're using to search will be turned on and used to tell you when you get closer (7).


If you notice the bottom of the screen shot, there's a little speaker symbol, it beeps intermittently and the beeping gets faster as you get closer to the lost device. The red bar also moves closer to the -25 mark (8). If you're not hearing the beeping, make sure to turn up the volume. If you still don't, then walk around until you do.


Once you've found the device, just pull down the notification bar and you'll see Radar mode active on there, indicating to touch to terminate. (9), (10). Once you do, the hotspot will turn off too.



Hopefully, you'll never have to use this, but now you're ready if you need to. Keep in mind, because of how this function works, if your phone was the only device that had both WiFi and data, you can use a computer to search for it through the website, but once you've got the location, if it's in a building and you want to use radar mode to narrow the search, you'll need to borrow someone else's Android phone and install the client app on it.


ETA: nu Kinja sucks at letting you space out images. So now they're numbered, and all at the bottom.

ETA 2: Thanks to nctrns telling me how to add line breaks after images, and a bout of non-laziness, I've put each image right after the text they apply to. I left the numers and stuff though.
