If you’re a Samsung user, you’ve probably experienced that weird moment when you wanted to install an app, open a secret code like #0 #, or connect your phone to a computer—but suddenly it all failed. Your phone denies access without any clear explanation. It could be that “Auto-Blocking” is silently running in the background.
What exactly is this feature? Why do some users find it annoying? And how do you properly disable it? This article will break it all down thoroughly, so that you not only understand its function but also know how to control it. Don't miss a single paragraph—because at the end, we'll share important tips that users often miss when turning off this feature.
What Is Samsung Auto-Blocking?
Samsung introduced the Auto Blocker feature as an additional layer of protection on their devices. The goal is clear: protect users from hidden threats such as malware, illegal USB commands, apps from outside the Play Store, and even unofficial system updates.
However, the more advanced a feature is, the more complicated the consequences. Many users feel restricted—even though they want more freedom to explore their devices, especially those who like to customize or use technical features such as the #0 # code for diagnosis.
Main Function of Auto Blocking
Before turning it off, you must know what exactly this feature blocks. Here is a brief explanation:
1. Block applications from unofficial sources
- Only apps from Google Play Store and Galaxy Store are allowed.
- Avoid potential malware from external APKs.
2. Block commands via USB cable
- Prevent hackers from accessing your phone through physical connections.
- Protects against unauthorized access when connected to a public computer or unknown charger.
3. Block suspicious images in messaging apps
- If an image is suspected of containing malware, the system will automatically prevent it from being displayed.
4. Block unofficial system updates
- Does not allow installation of firmware or custom ROMs not approved by Samsung.
5. Causes failure to access secret code
- Including the code #0 # which is usually used by technicians to check hardware conditions.
Then, Why Should It Be Turned Off?
This question is very important. Not all users need to turn off this feature. But for those of you who:
- Want to install apps from outside the Play Store (e.g. trial apps or developer apps).
- Need to access Samsung secret code like #0 #.
- Frequently use USB connection for debugging, data transfer, or manual installation.
- Perform system modifications (advanced users).
So turning off this feature can give you more freedom.

Things to Consider Before Deactivating It

Are Phones More Vulnerable?
Technically, yes. But the vulnerability is dependent on how you use it. If you’re a user who knows what you’re doing—and doesn’t just click or install random apps—then the risk can be managed well.
Samsung made this feature for the average user. But if you are an advanced user, managing security manually can be more flexible and controlled.
So the Control is in Your Hands
Samsung’s Auto-Blocking feature is meant to protect. But in some cases, it can feel restrictive. Turning it off isn’t a reckless move—as long as you know the risks and know how to stay safe on your own.
With the steps above, you can now unlock more potential from your Samsung device, especially if you are a developer, technician, or simply a user who wants full control over your phone.
