Android quietly slipped a photo scanner onto your phone — here's how to shut it off

Google has been updating its Android OS with beefier anti-theft and security features. Last year, Google also rolled out a system service to Android devices called Android System SafetyCore. A background service that silently monitors your phone for unwanted content, specifically mature content like nudity.

It all sounds good until you realize Google Messages can scan your inbox for images with sensitive content that includes nudity, spam, scams, or malware. But I'm not comfortable with the idea of having a background app scan through my texts and media. So, I went ahead and turned it off, which was easier than I thought.

What's Google's Android System SafetyCore?

A system service that scans your messages for sensitive images

Android System SafetyCore (package name com.google.android.safetycore) is a system service, not your usual app. It works as an on-device content classification layer that other apps, primarily Google Messages, can call to flag images as sensitive. Its main job right now is powering what Google calls "Sensitive Content Warnings" in Google Messages. When it detects an image that may contain nudity, it blurs the image and shows you a warning before you can view, send, or forward it.

But how did it get there? I certainly don't remember installing it. Google pushed SafetyCore through its monthly Google System Updates and Play Services, the same channel it uses for other behind-the-scenes components. Because it's treated as a privileged system service, the installation skipped the usual user-visible prompts. One day, it just showed up in the system app list under Settings > Apps > Show system apps with no warning.

Google says all classification happens on-device, meaning the images and results are not uploaded to its servers. For adults, the scanning feature is opt-in and turned off by default. For minors and supervised accounts, Google enables it by default and lets parents manage it through Family Link. But whether it's opt-in or not, the fact that a content-scanning service was quietly installed on millions of devices rubbed a lot of people the wrong way.

Turn off Sensitive Content Warnings in Google Messages

Disable the scanning without removing the app

If you'd rather not have Google Messages blurring images and flagging content in your inbox, you can turn off Sensitive Content Warnings without needing to uninstall SafetyCore entirely. The toggle is buried a few layers deep, but once you know where it is, you can turn it off in no time.

Open Google Messages, tap your profile picture in the top right corner, and go to Messages settings. Scroll down to Protection & safety and tap it. From there, tap Manage sensitive content warnings, which redirects you to your Google Account settings. On that page, toggle Warnings in Google Messages to off.

Once disabled, Google Messages stops blurring images and showing nudity warnings entirely. SafetyCore remains installed on your phone, but with the toggle off, it has fewer reasons to be invoked. This is also the step I'd recommend if you want to stop the scanning behavior but don't want to risk breaking any future safety features that might depend on the SafetyCore service, such as scam detection or spam filtering that Google has hinted at in its documentation.

For supervised child accounts, this toggle is not available on the device. Parents need to manage it through the Family Link app under the child's Sensitive Content Warnings controls.

Removing SafetyCore from Android

Uninstall it like any other app from settings

Even though the app was installed without user permission, you can remove it just like any other typical Android app from the Settings app. On most devices, including Pixels, this works without needing root access.

Open Settings, go to Apps, and tap See all apps. Open the three-dot menu at the top and choose Show system apps. Scroll down or search for Android System SafetyCore, tap it, and hit Uninstall. On some phones, SafetyCore also shows up in the Google Play Store, so you can search for it there and uninstall it that way if you prefer.

On certain devices, the Uninstall button may be greyed out because SafetyCore is treated as a baked-in system component. If that's the case, you'll see a Disable option instead. Tapping Disable stops the service from running and prevents it from scanning anything, even though the APK file stays on the phone. For most users, disabling works just as well as uninstalling.

One thing to keep in mind is that SafetyCore can come back after an Android OS update or a Google Play Services update. Google pushes it as a first-party system component, so future updates may quietly reinstall it. If that happens, you'll need to go back into Settings > Apps > Show system apps and uninstall or disable it again. It's worth checking after major system updates to make sure it hasn't returned. Your phone's default settings are already a privacy concern on their own, and SafetyCore sneaking back in only adds to that.

If you want a more permanent solution, root-level options exist. Magisk modules like AntiSafetyCore can block the package at the system level, and adb shell pm uninstall --user 0 com.google.android.safetycore may work on some OEMs if the package isn't flagged as protected. But these are advanced steps, and for most people, the Settings method is more than enough.

I don't need apps to scan my media

Google's SafetyCore service is, on paper, a reasonable safety feature. On-device scanning means your images don't leave your phone, and the nudity blur can be helpful for younger users or anyone who wants an extra layer of protection in their messages. The intent isn't the problem.

The problem is how it got there. A background service with content-scanning capabilities was pushed to millions of devices through a silent update, with no notification and no opt-in. That's sketchy, even when the underlying technology is privacy-preserving. Whether you choose to disable it, uninstall it, or leave it running with the toggle off, at least now you know it's there and what it does.
