How to delete the Advertising ID on Android
The Advertising ID is a unique string that is used for advertising purposes on Android devices. Powered by Google Play, the advertising ID is used by applications for monetization purposes.
Apps and advertisers may use the Advertising ID on Android for identification purposes, as it may provide them with information on user activity on the device. The information is then used to deliver personalized advertisement.
Starting in Android 12, Android users may delete the Advertising ID on a device so that it can't be used anymore by applications or advertisers. Previous versions of Android supported resetting the ID only, but not disabling it entirely. Google plans to bring the deletion option to previous versions of the Android operating system by April 2022.
As part of Google Play services update in late 2021, the advertising ID will be removed when a user opts out of personalization using advertising ID in Android Settings. Any attempts to access the identifier will receive a string of zeros instead of the identifier.
This Google Play services phased rollout will affect apps running on Android 12 starting late 2021 and will expand to affect apps running on all devices that support Google Play starting starting April 2022.
Delete the Android Advertising ID
Here is what you need to do to delete the Advertising ID on Android. Note that you can generate a new ID at any time after deleting it, which is also explained below.
- Open the Settings on the Android 12 or higher device.
- Go to Privacy > Ads.
- Activate the "Delete advertising ID" option on the page that opens. The page lists the current advertising ID and the "Reset advertising ID" option as well.
- A new page with information opens. It states that ads will still be displayed, but that they may be less relevant without the advertising ID. Additionally, apps may have other tracking means and may still be able to display personalized ads.
- Select the "Delete advertising ID" button on the page to proceed.
Once you activate the button, you are taken back to the Ads settings page. All options are gone and the new "Get new advertising ID" option is displayed instead. You may activate it at any time to generate a new unique advertising ID on the device.
Google's Privacy Sandbox for Android
Announced on February 16, 2022, Google plans to introduce "new, more private advertising solutions on Android" in the coming years. Called Privacy Sandbox for Android, it will "limit sharing of user data with third parties and operate without cross-app identifiers, including advertising ID".
You find the entire announcement on Google's The Keyword website.
Now You: what is your take on this development?
Thanks for the tip Martin.
It is for these kinds of posts that I follow GHacks.
What’s up with the generic comment, are you a bot?
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”??
@Martin
Your website has gone insane.
When I the post button I then saw my comment posted on a different article page. When I opened this article again, it is here.
@Tachy @Martin Brinkmann
” Your website has gone insane. ”
Same here. Has happened several times.
@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.
Why do you want people to disable the privacy features? Hmmmmm?
Now You: do you plan to keep the Ads privacy features enabled?
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]
@Martin
You website is still psychotic. Comments attach to random stories.
@Martin please do fix the comments, it’s completely insane commenting here! :[
@Martin
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.
What does this article has anything to do with all the comments on this article? LOL I think this Websuite is ran by ChatGPT. every article is messed up. Some older comments from 2015 shown up in recant articles, LOL
The picture captioned “Clearing the Android Auto’s cache might resolve the issue” is from Apple Carplay ;)
How about other things that matter:
Drop survival?
Screen toughness?
Degree of water and dust protection?
