Most smartphone users are surprised when they discover apps on their phones that they never knowingly installed. Even more concerning is when these apps don’t show up in the usual app drawer, leaving people suspicious about their purpose.
Recently, two hidden applications developed by Google were spotted on Android devices. Many users initially assumed these apps were secretly spying on their activity. But the truth is a little more complex. In this detailed guide, we’ll explore what these apps do, why they’re on your phone, whether they are safe, and how to remove them if you wish.
1. Why Are Hidden Apps Installed?
Let’s begin with the obvious question—why would Google install applications that don’t appear in your normal app drawer?
The answer lies in system-level services. Unlike user-installed apps (like WhatsApp or Instagram), these apps perform background tasks essential for newer Android features. They don’t require user interaction, which is why they don’t clutter the app menu.
However, because they are invisible to most users, many people feel uneasy when discovering them in the “Installed Apps” list inside phone settings. The suspicion often comes from the secrecy, not the functionality.
2. What Is “Android System Key Verifier”?
One of the first hidden apps reported by users is called Android System Key Verifier.
At first glance, it looks suspicious. Its permissions are hidden, and you won’t find an icon to launch it. But once you dig deeper, you realize it serves a very specific purpose.
Purpose and Permissions
The app’s primary role is to verify encryption keys during RCS (Rich Communication Services) messaging.
Normally, SMS messages are not encrypted, meaning anyone who intercepts them can read the contents. RCS, Google’s newer messaging protocol, adds end-to-end encryption. This makes messages much harder to intercept.
But encryption only works if both sides are using correct keys. That’s where the Android System Key Verifier steps in. It checks whether the encryption keys between sender and receiver match, ensuring no tampering occurred.
How It Relates to Encrypted Messaging
Think of this app as a digital referee. It doesn’t read your messages, but it confirms that the keys used to encrypt and decrypt your chats are authentic. Without this check, end-to-end encryption could be compromised.
To see it in action, you can:
- Open the Google Messages app.
- Tap on your profile photo (top-right corner).
- Select Messages Settings > RCS Chats.
Here, you’ll find options related to encrypted chat, which rely partly on the Android System Key Verifier for security.
Steps to Locate and Remove It
If you still want to view or uninstall this app:
- Open the Google Play Store.
- Tap your profile photo in the top-right corner.
- Scroll down and select Help & Feedback.
- Search for “delete apps.”
- Follow the link to open Application Settings.
- In the search box, type Android.
- Locate Android System Key Verifier.
- If you decide to remove it, tap Uninstall and confirm.
👉 Note: Removing it may affect RCS message encryption. If you frequently use secure messaging, keeping it installed is safer.
3. What Is “Android System Safety Core”?
The second hidden application is Android System Safety Core.
This one raised even more eyebrows because it scans images sent or received via messaging apps.
How It Scans Images
According to reports, the app scans only the photos that are exchanged through apps like Google Messages. Its purpose is to detect explicit or pornographic content. If such content is identified, it automatically blurs the image and asks if you want to view it.
Google’s Explanation on Privacy
Google claims that this scanning happens locally on your device—meaning the photos are not uploaded to Google servers. In theory, this ensures your private images never leave your phone.
Still, the idea of a hidden app scanning images, even locally, makes some users uncomfortable.
Steps to Locate and Remove It
To find and uninstall Android System Safety Core:
- Open Application Settings (as shown in the steps above).
- Search for Android.
- Locate Android System Safety Core.
- Tap on it.
- Select Uninstall and confirm.
👉 Note: Removing this app won’t break core phone features, but it may disable Google’s ability to automatically filter explicit content in messages.
4. Understanding RCS Messaging and Why It Matters
Before we move further, it’s important to understand RCS Messaging, since both hidden apps are linked to it.
RCS is essentially the modern replacement for SMS/MMS. It supports:
- End-to-end encryption,
- Higher quality image sharing,
- Typing indicators,
- Read receipts,
- Group messaging improvements.
However, because RCS involves encryption, it requires apps like Android System Key Verifier to function properly. Without it, encryption might be unreliable or even vulnerable.
If you’ve ever noticed your Google Messages app showing messages labeled as “encrypted,” these hidden apps were part of the process keeping your chat private.
5. Do These Apps Really Threaten Privacy?
This is the heart of the debate. Do these hidden apps exist to protect us or to spy on us?
Arguments for Safety
- Google has publicly documented their purpose.
- Permissions indicate no external data sharing.
- Functions (encryption verification, local scanning) are tied to known features.
Concerns Users Have
- Lack of transparency: Apps should be visible and documented upfront.
- Image scanning, even local, feels intrusive.
- The ability to uninstall shows they are not strictly “mandatory,” which raises questions.
Ultimately, whether you keep or remove them depends on your comfort with Google’s privacy practices.
6. Step-by-Step Guide to Finding and Removing Hidden Google Apps
If you want to double-check whether these apps are on your phone and decide for yourself, here’s a full walkthrough.
Step 1: Open Play Store
- Launch the Google Play Store app.
- Tap on your profile photo in the top-right corner.
Step 2: Access Help & Feedback
- Scroll down and select Help & Feedback.
- In the search box, type delete apps.
- Select the result that allows you to open Application Settings.
Step 3: Search Installed Apps
- Once inside Application Settings, tap on the search bar.
- Type Android.
- You’ll see a list of apps beginning with Android System.
Step 4: Locate Suspicious Apps
- Look for Android System Key Verifier.
- Look for Android System Safety Core.
Step 5: Review or Uninstall
- Tap on the app name.
- Select Permissions and review what it has access to.
- If you wish to remove it, tap Uninstall and confirm.
👉 Important Warning: Uninstalling these apps might impact RCS chat features or explicit-content filters. Always weigh functionality against privacy before deciding.
7. Frequently Asked Questions
Q1: Why doesn’t Google list these apps in the app drawer?
Because they are designed as system-level tools, not user-facing apps. They run silently in the background.
Q2: If these apps are safe, why allow users to uninstall them?
Google likely gave users this option to comply with regional privacy regulations and to provide transparency after public concerns.
Q3: Can uninstalling these apps improve phone performance?
Not significantly. These apps are lightweight and don’t consume noticeable resources.
Q4: Do these apps work on all Android phones?
They are primarily installed on phones running Google’s Android services (Pixel devices and most brands using Google’s software stack). Phones using custom ROMs or without Google services may not have them.
Q5: Should I keep or remove these apps?
If you use RCS messaging and value encrypted communication, keeping Android System Key Verifier is advisable. If you dislike automatic content filtering, you can remove Android System Safety Core.
8. Final Thoughts and Recommendations
Discovering hidden apps on your phone can be alarming, especially when they are installed without your consent. However, after closer inspection, the Android System Key Verifier and Android System Safety Core apps appear to serve legitimate purposes: one protects encrypted messages, the other filters explicit content locally.
That said, privacy is deeply personal. While some users will feel reassured knowing these apps are harmless, others may prefer uninstalling them for peace of mind. The important part is that you now know:
- What these apps are,
- Why they exist,
- How to find and remove them if you choose.
Stay aware of what’s running on your device, regularly check app permissions, and make informed choices about your digital privacy.
