You can now lock your device with Android Device Manager

Google introduced the new Android Device Manager web service back in August. It allows you to run commands, such as locating your phone or to erase all data on it. This can be useful to find your phone if you have misplaced it, or to make sure that all data on the phone is deleted if you suspect or know that it has been stolen.

The feature needs to be enabled on the Android device before it becomes available. I have posted instructions on how to do so back in August. You need to open the Settings of your device, select Security, and there Device administrators to do so.

Google has rolled out a new feature recently that adds another remote control feature to the Android Device Manager. Besides locating the device and erasing data on it, it is now possible to lock it instead.

The process won't just lock the phone or tablet running Android, but also change the lock screen password as well. The Device Manager overrides any form of protection that you have set on the device, which can be useful if you suspect that the person who has it now knows the original unlock code.

To use the new locking feature, visit the Android Device Manager service website after you have enabled it on your device.

Here you see a list of all options available at your disposal. The website will check for your phone's location automatically, but that may not work depending on whether you have enabled location-based settings on the device or not.

The option to lock the phone has been prominently placed here next to the ring and erase features. When you select the lock option you are asked to enter a new password that will be used to lock the device. Note that this only works if the phone or tablet are connected to the Internet. If it is not, it will be locked as soon as it is connected again.

The request will lock the device automatically so that it cannot be used anymore unless the right code is entered to unlock it.

Closing Words

The option to lock the device comes in handy if you do not know if you have misplaced your device or if it has been stolen. While you could erase all data to make sure it does not fall into the wrong hands, it is not the best option if you find your phone or tablet again.

Locking makes sure that third parties cannot access your data while you can if you find it again.

    2G?

    Where on the planet is that still in use? I was forced to give up using my RAZRV3 years ago because 2G was phased out by AT&T.

      Everywhere 3G has been turned off and you don’t have LTE coverage, and believe me there are many developed countries where this is the case and if it weren’t for 2G you wouldn’t even be able to make a phone call.

      Maybe I missed it, but I don’t believe tha term “2G” is in the article. Perhaps you are referring to “AGM G2”??

        @Tachy,
        @Martin P.,

        For over two weeks now,
        I’ve been seeing “Comments” posted by subscribers appearing in different, unrelated articles.

        For the time being,
        it would be better to specify the “article name and URL” at the beginning of the post.

    @tachy a lot of non-phone devices with a sim in them rely on 2G, at least here in europe.
    Usually things reporting usage or errors/alarms on something remote that does not get day to day inspection in person. They are out there in vast numbers doing important work. Reliable, good range. The low datarate is no problem at all in those cases.
    3G is gone or on its last legs everywhere, but this stuff still has too much use to cancel.

    Anyhow, interesting that they would put that in. I can see the point if you suspect a hostile 2G environment (amateur eavesdroppers with laptop, ranging up to professional grade MITM fake towers while “strangely” not getting the stronger crypto voip 4G because it is being jammed, and back down to something as old ‘stingray’ devices fallen into the wrong hands).

    But does this also mean that they have handled and rolled out a fix for that nasty 4G ‘pwn by broadcast’ problem you reported earlier this year? I had 4G disabled due to that, on the off chance that some of the local criminals would buy some cheap chinese gear, download a working exploit and probe every phone in range all over town in the hope of getting into phones of the police.

    >”While most may never be attacked in stingrays, it is still recommended to disable 2G cellular connections, especially since it does not have any downsides.”

    The downside would be losing connectivity. I spend a lot of time way out in the countryside where there’s often no service or almost none. My network allows 2G, and I need it sometimes. I have an option on the phone to disable 2G, I may do that when I’m in the city and I have good 5G connectivity, but not out in the country.

    I would imagine that the stingray exploits, like most of the bad things in this world, are probably things you will run into in the crowded big cities.

    I stopped using it in a mobile (Wi-Fi line) environment, so I’m almost ignorant of the actual situation,
    But the recent reality in Japan makes me realize that “the infrastructure of the web is nothing more than a papier-mâché fiction”.

    It is already beyond the scope of what an individual can do.
    What we should be aware of is the reality that “governments and those in power want to control the world through the Web”, and efforts to counter (resist and prevent) such ambitions are necessary.

    I’d like to tell you, but apparently if you make a post critical of Google, you get censored. * [Editor: removed, just try to bring your opinion across without attacking anyone]

    The comments are seriously messed up on gHacks now. These comments are mixed with the article at the below URL.

    https://www.ghacks.net/2023/08/18/android-how-to-disable-2g-cellular-connections-to-improve-security/

    And comments on other articles are from as far back as 2010.

    How about other things that matter:

    Degree of water and dust protection?
