Google finally rolled out the stable Android 15 update to Pixel devices today, bringing lots of new features like Private Space, app archiving, predictive baking animations, and more. However, the stable update does not include some of the features we discovered during the Android 15 beta program, such as the entry point for the Device Diagnostics app in Settings, as well as the new cellular security features that Google announced at I/O . That’s why the Android 15 update doesn’t have these new cellular security features.

To illustrate, the first beta of Android 15 introduced a new settings page called “Mobile Network Security” below Settings > Security and privacy > More security and privacy. This page was later renamed to “Mobile network security” in a later beta, which also added a description that said, “These settings help protect your calls, messages, and data from outdated or unencrypted networks that could expose you to data theft or surveillance.”

There were two switches on the mobile network security page: “Network notifications” And “Only allow encrypted networksThe Network Notifications feature allows you to be “notified when your device connects to an unencrypted network or when a network records your unique device or SIM ID.” The “Allow only encrypted networks” setting improves the security of your mobile network connections at the expense of limiting your network options in some locations, but emergency calls should still go through.

As Google explained at I/O, these mobile security features are aimed at “defending against abuse by criminals who use mobile simulators to spy on users or send them SMS-based scam messages.” The technical terms for these Android 15 features were Cellular Cipher Transparency and Identifier Disclosure Transparency and they are intended to protect you from rogue “Stingray” tracking devices.

While these features are part of Android 15’s source code, they are not available out of the box because, according to Google, they “require device OEM integration and compatible hardware.” Given that these features appeared to be available to Pixel users during the Android 15 beta, it’s reasonable to assume that Pixel phones will support them. However, as it turns out, that’s not the case, as the visibility of the Cellular Security settings page on Pixel phones was just a bug.

It turns out that none of the current Pixel phones – not even the four phones in the Google Pixel 9 series – currently support Android 15’s new mobile security features. According to an issue tracker post, Google actually hidden the Mobile Network Security settings page from Pixel users in Android 15 Beta 4 and then prevented it from appearing in search in Android 15 Beta 4.2. In a now-deleted comment on the same Issue Tracker post, a Google employee specifically stated that the visibility of Android 15’s mobile network security settings was tied to hardware support.

This comment was made before the launch of the Pixel 9 series, so there is a possibility that Google’s latest devices may support this feature. However, today I confirmed that the page doesn’t even appear on the Pixel 9 Pro after it updated to Android 15. However, it’s possible that this will change in a future release, as Google’s mention of hardware support may refer to wireless driver/HAL support, which it was able to implement with the help of its modem provider (Samsung).

Google said at I/O that it is “working with the Android ecosystem to bring these features to users” and that it “expects OEM adoption to progress over the next few years,” so here’s hoping that these new cellular security features will actually make their way to some Android devices in the near future.
