The problem? Samsung’s Secure Folder had a critical vulnerability that allowed anyone with physical access to peek into your hidden apps and photos. Worse yet, apps inside the Secure Folder could be detected through the system’s Permissions Manager, completely defeating the purpose of keeping them “safe.” Here’s the kicker: Samsung treats Secure Folder as a managed work profile, meaning your data is simply kept separate from your personal profile.
What you need to know:
- Samsung acknowledged Secure Folder vulnerability that exposed hidden apps and photos
- The flaw arose from Secure Folder’s dependency on Android’s work profile system.
- Samsung plans to adopt Google’s Private Space API for a suitable solution
- Fix may not arrive until One UI 8 is released
The security flaw that broke the “secure” promise
Let’s analyze what went wrong. A Reddit user discovered a flaw that allows anyone with physical access to your phone to take a look at the apps and photos stored in Samsung’s Secure Folder. The problem wasn’t just theoretical: it was embarrassingly easy to exploit.
The issue is related to work profiles, which allow files to be extracted from the Secure Folder without requiring additional authentication. This architectural flaw suggests that Samsung never properly audited work profile permissions before building Secure Folder on top of them, a fundamental oversight that compromises the entire security model.
After extensive testing, Android Authority’s Mishaal Rahman confirmed the flaw and showed that media files in Secure Folder were exposed. The vulnerability worked because apps in the work profile can use Android’s photo picker to access your “safe” photos and videos, completely bypassing the lock that you thought kept them safe.
Permissions Manager vulnerability reveals deeper systemic issues. If someone digs into the system settings and checks the Permissions Manager, they can see a list of apps that have requested permissions, including the ones you thought were safely stored in the Secure Folder. This exposure occurs because Android’s permissions system was not designed to hide work profile apps from system-level visibility; treats them as legitimate corporate applications that should be discoverable for administrative purposes.
Why the work profile approach failed
This is where Samsung’s engineering decisions backfired. The problem comes down to how Secure Folder is built into Android’s Work Profile feature, which was initially intended for corporate setups.
This architectural choice created multiple attack vectors that Samsung apparently never considered. Whether set up by a company or through third-party applications, work profiles breach Secure Folder defenses and put sensitive data at risk. This security flaw is not limited only to work profiles configured by companies: it also affects those created through third-party applications.
The fundamental problem was that Samsung treats Secure Folder as a managed work profile, meaning your data is simply kept separate from your personal profile. Samsung should have implemented true isolation using existing Android security frameworks instead of reusing enterprise management tools. This design choice reveals a worrying gap in how Samsung approaches consumer privacy versus corporate data management.
The consequences extend beyond individual users. In certain scenarios, that setting left your photos, videos, apps, and files vulnerable to access. An employer could see what’s inside the Secure Folder, or Android’s permissions manager could show the full list of apps it contains. This creates potential legal and privacy implications for users who assumed their personal data was truly isolated from corporate oversight.
Samsung’s solution: adopt Google’s private space API
Good news: Samsung is not ignoring the problem. Now it looks like Samsung will follow Google’s lead and adopt the new Private Space API for its own Secure Folder. This represents a fundamental change in the way Samsung approaches mobile privacy.
What this means for you is that your content inside Secure Folder will be truly secure (isolated from the rest of the system) and won’t accidentally appear where it shouldn’t. Google’s Private Space API solves the fundamental architectural problems that Samsung created by establishing true isolation at the system level instead of relying on enterprise management frameworks.
The technical improvements are significant. The reason is that Google created a completely new user type for Private Space – android.os.usertype.profile.PRIVATE – which the photo picker and Permissions Manager treat differently. Android recognizes when a private profile is locked and then hides it from the photo picker, permissions manager, and other system services. This new type of user fundamentally changes the way Android handles permission requests, ensuring that private profile apps remain invisible to system-level discovery mechanisms.
One UI 8 will bring additional security improvements that address the notification leak issue. Now that Samsung Secure Folder in One UI 8 uses the Private Space API instead of the work profile, we can hope that the known security flaw has been fixed. Plus, you won’t even receive notifications from hidden apps when Secure Folder is locked. This suggests that other Android manufacturers using similar work profile-based implementations should also consider migrating to Google’s Private Space API to avoid Samsung’s mistakes.
What this means for your Galaxy device
The schedule is disappointing, but the solution is yet to come. The leaker suggests that Samsung will implement the fix only with the launch of One UI 8. Although Android 16 is just around the corner, the next major version of One UI could still be a long way away, especially considering the delay of One UI 7.
In the meantime, you can try to prevent photos and videos from being viewed outside the secure folder by encrypting it. Samsung has apparently acknowledged the security flaws, but the company has not yet shared any concrete plans to fix them.
Samsung’s decision to wait for One UI 8 instead of rolling out an emergency fix reveals its security update prioritization strategy. The company appears to include major architectural changes with major operating system updates rather than rolling out critical security fixes as standalone patches. This approach prioritizes system stability over immediate security fixes, which may not align with users’ expectations of critical privacy vulnerabilities. For users storing truly sensitive content, consider workarounds like encrypted cloud storage or third-party privacy apps until a fix arrives.
One UI 8 will introduce additional protection measures that go beyond Google’s basic implementation. A kind of kill switch has been added to Secure Folder, ensuring optimal protection against unauthorized access. When hidden, all apps and data in the secure folder are encrypted.
PRO TIP: Until a fix arrives, avoid using work profiles if you rely on Secure Folder for truly sensitive content. Consider encrypting your secure folder as an extra layer of protection, and review your Permissions Manager settings to see which apps may be visible to others.
The Bigger Picture: Mobile Security in the Age of AI
This Secure Folder fiasco highlights a broader challenge in mobile security as personal data becomes increasingly valuable for AI training and personalization. Samsung introduces Knox Enhanced Encrypted Protection, a new architecture designed to safeguard the next generation of personalized AI-powered features. It’s clear that the company is taking security more seriously as AI functions become more personal and invasive.
The connection between Secure Folder’s flaws and AI security needs becomes clear when data confidentiality is considered. KEEP creates encrypted, app-specific storage environments within the device’s secure storage area, ensuring that each app can access only its own sensitive information and nothing else. This represents the kind of fundamental security thinking that should have been applied to Secure Folder from the beginning: true isolation rather than administrative separation.
The KEEP architecture demonstrates Samsung’s evolution from work profile failure to proper security design. Application-specific encrypted storage is more important as AI functions become more personal because these systems need access to deeply personal data patterns while maintaining strict boundaries between applications. Samsung’s acknowledgment of the Secure Folder flaw and its architectural pivot to KEEP shows that they are learning from this mistake, but it took a public safety failure to force this improvement.
The lesson here? Security features must be secure by design, not just by promise. Samsung’s acknowledgment of the flaw and commitment to fixing it through Google’s Private Space API shows that they are learning from this mistake. Now we just have to wait for One UI 8 to deliver on that promise.
