Samsung Galaxy's Auto Blocker Feature Protects Against Untrustworthy Apps and Commands
Key points
- Auto Blocker is a security feature on Samsung Galaxy phones with One UI 6.0+.
- It blocks app installations from unofficial sources and malicious USB commands.
- The feature also filters images in messaging apps for malicious code.
- A "Maximum restrictions" mode offers additional security measures.
Samsung Introduces Auto Blocker
Samsung Galaxy devices running One UI 6.0 or later now include a security feature called Auto Blocker. This feature is designed to protect users from untrustworthy applications and commands. It is enabled by default on devices shipped with One UI 6.1.1 or newer.
Core Functionality
Auto Blocker primarily prevents the installation of applications from sources outside the Google Play Store or Samsung Galaxy Store. This action closes a common pathway for malware to infect devices. Additionally, it blocks malicious commands that could be sent via a USB cable, addressing risks associated with public charging stations. The feature also filters images received in messaging applications like Samsung Messages, Google Messages, Messenger, WhatsApp, and Telegram, identifying and blocking those suspected of containing malicious code.
Advanced Protections
For users seeking enhanced security, Samsung offers a "Maximum restrictions" mode within Auto Blocker. This mode introduces further safeguards, such as blocking device administration apps and work profiles, disabling 2G network connections, preventing automatic reconnection to unsecured Wi-Fi networks, and stripping location data from shared photos. This more aggressive setting prioritizes security over convenience.
User Control and Impact
While Auto Blocker provides a significant security layer, it can interfere with users who frequently sideload applications or utilize developer tools. The feature's presence has been a point of contention, with Epic Games having previously filed a lawsuit against Samsung, arguing that it complicated the process of downloading third-party applications. Users can choose to enable, disable, or adjust the settings of Auto Blocker based on their specific needs and risk tolerance.
