Android feature prevents sensitive content in Google Messages

Have you ever stumbled upon a mysterious app in your Android system settings called “SafetyCore”? If so, you’re not alone. Introduced in late 2024, this system service aims to enhance on-device privacy by detecting sensitive content like nudity and enabling features such as Sensitive Content Warnings in Google Messages. 

While Google assures users that SafetyCore operates locally without sharing data externally, it has still sparked confusion over automatic updates. Let’s dive into what SafetyCore does, how it works and the steps you can take to disable it if you choose to do so.

What you need to know

By definition, SafetyCore is a system service that provides on-device machine-learning infrastructure to help detect sensitive content. It was introduced as part of Google’s Nov. 7, 2024, system update for Android 9 and later.

Google initially described SafetyCore as a tool that supports privacy-preserving user protections for apps. One of its first visible uses was in Google Messages, where it enables Sensitive Content Warnings, a feature that blurs images potentially containing nudity and prompts users with additional options before they can view or send them.

By default, Google System services automatically update your device with security, bug fixes and new features. Some updates are delivered via system services in separate Android packages. This maintains privacy, security and data isolation following the principle of least privilege because permissions are not shared with other functionality.

SafetyCore does more than detect nude images. Its built-in machine-learning functionality can also target, detect and filter images for sensitive content. There is no app icon, and it doesn’t appear in the usual list of running applications. Users must navigate through Settings Apps Show system processes to find it.

What does Google say?

Google maintains that SafetyCore is purely an on-device classification service and does not report or share scanned content with Google or other entities. The company argues that the service enhances security without compromising privacy, allowing apps to detect and filter unwanted content locally.

We reached out to Google, and a spokesperson told Cyberguy, “Android provides many on-device protections that safeguard users against threats like malware, messaging spam and abuse protections, and phone scam protections, while preserving user privacy and keeping users in control of their data.

“SafetyCore is a new Google system service for Android 9+ devices that provides the on-device infrastructure for securely and privately performing classification to help users detect unwanted content. Users are in control over SafetyCore, and SafetyCore only classifies specific content when an app requests it through an optionally enabled feature.”

Google also says that as part of its continuous investment in the transparency of its products, the company is going above and beyond, adding binary transparency to SafetyCore. This allows users and developers to verify that SafetyCore is truly privacy-preserving, just like Google says it is.

4 ways to keep your personal information safe

If you’re concerned about Google’s data collection and want to keep your personal information safe, here are four steps you can take.

1) Limit app permissions: Regularly review and restrict app permissions, especially for access to your camera, microphone, storage or location. If an app doesn’t need access, revoke it in your device settings.

2) Disable background data and tracking: Prevent unnecessary tracking by turning off background data for apps that don’t require constant internet access. You can also disable location tracking and opt out of Google’s personalized ads in your account settings.

3) Use a VPN for secure browsing: A VPN (virtual private network) encrypts your internet traffic, preventing your ISP, Google or other entities from tracking your online activity. Privacy-focused VPNs are great options that do not log user data. For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices.

4) Regularly clear personal data: Delete unnecessary stored data such as search history, location history and cached files. You can do this in your Google Account settings and within individual apps to minimize your digital footprint.

Kurt’s key takeaway

SafetyCore is an interesting addition to Android, offering on-device content filtering with machine learning. While it aims to enhance privacy and security, some users might have questions about its presence and functionality. Whether you decide to keep it or explore disabling it, staying informed about your device’s features is always a good idea. This way, you can make choices that best fit your needs and preferences for managing your Android device.

It’s amazing how good Alienware’s $350 OLED monitor is

It’s amazing how good Alienware’s 0 OLED monitor is

I’ve recommended several OLED gaming monitors to readers over the years, and I’ve finally taken my own advice to buy one. Alienware’s new 27-inch 1440p QD-OLED has all the features that I want and a low $350 price that was too tempting to ignore.

The AW2726DM model has five things that make it stand out for the price: a 1440p QD-OLED screen with lush contrast, a fast 240Hz refresh rate, a semi-glossy screen coating to enhance details, a low-profile design without flashy RGB LEDs, and a great warranty (three years with coverage for burn-in).

I’ve been using Alienware’s new monitor for a couple days, and I’ve already spent hours with it playing Marathon. It was my first opportunity to see Bungie’s new first-person extraction shooter in its full HDR glory, and I can never go back. Switching on HDR wasn’t automatic, though it already looked so much better than my IPS panel without being activated.

Enabling it transformed how Marathon looked for the better, but made everything else about the OS look pretty washed-out. It’s a Windows issue, not an Alienware issue. It’s easy to enable HDR every time I launch a game and disable it afterward with the Windows + Alt + B keyboard shortcut, but unfortunately triggers HDR for all connected displays. This includes my IPS monitor that imbues everything with a terrible gray hue when HDR is on. So, using the system settings is the best way to adjust HDR for just the QD-OLED.

I landed on this QD-OLED after having spent a ton of time researching pricier models. The unanimous takeaway from reviewers was that LG’s Tandem RGB WOLED panels are some of the brightest out there, but also tend to exhibit lousy gray uniformity in dark scenes. QD-OLED monitors, on the other hand, offer slightly better contrast than WOLED and don’t suffer from those same uniformity issues. However, blacks sometimes appear as dark purple in bright rooms on QD-OLED panels, meaning they’re ideal for rooms that don’t have a bunch of light bouncing around.

There’s no perfect choice, and honestly I got tired of doing research, so I jumped in with the cheapest OLED. I’m glad that I did. Shopping for an OLED gaming monitor can be hard, but it can also be this easy. AOC makes a model that’s discounted to $339.99 at the time of publishing, and its specs are comparable.

As expected, the AW2726DM isn’t a cutting-edge monitor. Its QD-OLED panel isn’t as fast or as bright as some other pricier options, and it doesn’t have USB ports for connecting accessories. Considering its low price, it’s easy for me to overlook those omissions. I’d have a much harder time accepting them in a pricier display.

The fact that I mostly use my computer for text-based work at The Verge is what prevented me from upgrading to an OLED monitor. My 1440p IPS monitor is bright, it’s good at showing text clearly, and it has a fast refresh rate for gaming. Alienware’s QD-OLED is less bright, and some might be bothered by how text looks (I have to really squint to see the slight fringing from this QD-OLED’s subpixel layout). But I have a life outside of work, which includes playing a lot of PC games. That’s the slice of myself I bought this monitor for, and I’m so happy I did.

Michael and Susan Dell surpass  billion in donations backing AI-driven hospital project

NEWYou can now listen to Fox News articles!

Billionaire Michael Dell and his wife, Susan Dell, have become the first donors to give more than $1 billion to the University of Texas at Austin, funding a massive new medical research campus and hospital system powered by artificial intelligence.

The couple’s latest investment includes a $750 million gift to help build the UT Dell Medical Center, a planned “AI-native” hospital expected to open in 2030 as part of a more than 300-acre advanced research campus.

University officials said the project will integrate research, clinical care and advanced computing to improve early disease detection, personalize treatment and expand access to care in the rapidly growing Austin region.

The Dells’ support builds on decades of contributions to UT, including funding for its medical school, scholarships and research programs.

“By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond,” Michael Dell and Susan Dell said.

The gift ranks among the largest in the history of higher education, alongside major contributions like Phil Knight’s $2 billion pledge to Oregon Health & Science University and Michael Bloomberg’s $1.8 billion donation to Johns Hopkins University.

The new UT Dell Medical Center will be developed in collaboration with MD Anderson Cancer Center, integrating cancer care into a system designed to connect prevention, diagnosis and treatment.

“We will deliver better outcomes for patients by providing research-driven cancer care that is precise, compassionate and hope-filled,” Peter WT Pisters, president of UT MD Anderson, said.

Officials said the facility will be built from the ground up to incorporate AI, rather than retrofitting older infrastructure — an approach they say could transform how hospitals operate.

Independent experts have cautioned that AI in health care can introduce risks if not carefully validated. A widely cited study published in the journal Science by researchers at the University of California, Berkeley and the University of Chicago found that a commonly used healthcare algorithm underestimated the needs of Black patients due to biased training data, highlighting broader concerns about equity in AI-driven systems.

The project also includes funding for undergraduate scholarships, student housing and the Texas Advanced Computing Center, where officials are developing one of the nation’s most powerful academic supercomputers.

Texas Gov. Greg Abbott said the investment will help position the state as a national leader in healthcare innovation.

“Texas already dominates in technology, energy and business, and now we will further cement our leadership in health care innovation as well,” Abbott said.
