SafetyCore Placeholder so if it ever tries to reinstall itself it will fail due to signature mismatch.

Google says that SafetyCore “provides on-device infrastructure for securely and privately performing classification to help users detect unwanted content

Cheers Google but I'm a capable adult, and able to do this myself.

Thnx for this, just uninstalled it, google are arseholes

People don't seem to understand the risks presented by normalizing client-side scanning on closed source devices. Think about how image recognition works. It scans image content locally and matches to keywords or tags, describing the person, objects, emotions, and other characteristics. Even the rudimentary open-source model on an immich deployment on a Raspberry Pi can process thousands of images and make all the contents searchable with alarming speed and accuracy.

So once similar image analysis is done on a phone locally, and pre-encryption, it is trivial for Apple or Google to use that for whatever purposes their use terms allow. Forget the iCloud encryption backdoor. The big tech players can already scan content on your device pre-encryption.

And just because someone does a traffic analysis of the process itself (safety core or mediaanalysisd or whatever) and shows it doesn't directly phone home, doesn't mean it is safe. The entire OS is closed source, and it needs only to backchannel small amounts of data in order to fuck you over.

Remember the original justification for clientside scanning from Apple was "detecting CSAM". Well they backed away from that line of thinking but they kept all the client side scanning in iOS and Mac OS. It would be trivial for them to flag many other types of content and furnish that data to governments or third parties.

Gimme Linux phone, I’m ready for it.

More information: It's been rolling out to Android 9+ users since November 2024 as a high priority update. Some users are reporting it installs when on battery and off wifi, unlike most apps.

App description on Play store: SafetyCore is a Google system service for Android 9+ devices. It provides the underlying technology for features like the upcoming Sensitive Content Warnings feature in Google Messages that helps users protect themselves when receiving potentially unwanted content. While SafetyCore started rolling out last year, the Sensitive Content Warnings feature in Google Messages is a separate, optional feature and will begin its gradual rollout in 2025. The processing for the Sensitive Content Warnings feature is done on-device and all of the images or specific results and warnings are private to the user.

Description by google Sensitive Content Warnings is an optional feature that blurs images that may contain nudity before viewing, and then prompts with a “speed bump” that contains help-finding resources and options, including to view the content. When the feature is enabled, and an image that may contain nudity is about to be sent or forwarded, it also provides a speed bump to remind users of the risks of sending nude imagery and preventing accidental shares. - https://9to5google.com/android-safetycore-app-what-is-it/

So looks like something that sends pictures from your messages (at least initially) to Google for an AI to check whether they're "sensitive". The app is 44mb, so too small to contain a useful ai and I don't think this could happen on-phone, so it must require sending your on-phone data to Google?

Google says that SafetyCore “provides on-device infrastructure for securely and privately performing classification to help users detect unwanted content. Users control SafetyCore, and SafetyCore only classifies specific content when an app requests it through an optionally enabled feature.”

GrapheneOS — an Android security developer — provides some comfort, that SafetyCore “doesn’t provide client-side scanning used to report things to Google or anyone else. It provides on-device machine learning models usable by applications to classify content as being spam, scams, malware, etc. This allows apps to check content locally without sharing it with a service and mark it with warnings for users.”

But GrapheneOS also points out that “it’s unfortunate that it’s not open source and released as part of the Android Open Source Project and the models also aren’t open let alone open source… We’d have no problem with having local neural network features for users, but they’d have to be open source.” Which gets to transparency again.

The app reviews are a good read.

The countdown to Android's slow and painful death is already ticking for a while.

It has become over-engineered and no longer appealing from a developer's viewpoint.

I still write code for Android because my customers need it - will be needing for a while - but I've stopped writng code for Apple's i-things and I research alternatives for Android. Rolling my own environment with FOSS components on top of Raspbian looks feasible already. On robots and automation, I already use it.
