The company is now making it clear that enabling these features is a crucial step in protecting against evolving threats.

The Rising Tide of Smartphone Theft and Data Breach Concerns

Smartphone theft continues to be a significant problem worldwide. Thieves often target devices not just for their resale value, but for the wealth of personal data they contain. A stolen phone can quickly become a gateway to bank accounts, social media profiles, email, and other sensitive information, leading to financial fraud, identity theft, and severe privacy breaches. In response to these escalating risks, Samsung has invested heavily in developing and integrating advanced security measures within its One UI ecosystem.

The company’s latest One UI 7 update, which has begun rolling out to compatible Galaxy devices, brings with it several new and enhanced security capabilities designed specifically to combat phone theft and unauthorized access. These features work in conjunction with the foundational security provided by Samsung Knox, a defense-grade security platform embedded in Galaxy hardware from the moment of manufacture.

New and Enhanced Theft Protection Features in One UI 7

With One UI 7, Samsung has introduced a suite of “Theft Protection” features, building upon existing Android safeguards. These new additions are particularly aimed at more sophisticated theft scenarios, including those where a thief might have gained knowledge of the device’s PIN.

• Identity Check: This feature adds an extra layer of biometric authentication for sensitive security settings. If your phone is in an unfamiliar location, any attempt to change critical security settings will require your fingerprint or face scan. This means that even if a thief manages to guess or obtain your PIN, they won’t be able to easily alter your device’s security protocols or access highly sensitive data without your biometric verification. This is particularly relevant for settings related to remote wiping or locking.
• Security Delay: A critical component of Identity Check, Security Delay introduces a one-hour waiting period if someone attempts to reset biometric data on your device. This crucial buffer provides a window of opportunity for the legitimate owner to remotely lock or wipe the stolen phone using another connected device, such as a PC or tablet, before unauthorized access can occur. This feature is designed to frustrate thieves who might immediately try to disable biometric security upon stealing a device.

These new features complement existing robust anti-theft capabilities that Samsung is also encouraging users to activate and ensure are configured properly:

• Theft Detection Lock: This intelligent feature uses machine learning to detect motions commonly associated with phone theft, such as snatching. Upon detecting such suspicious movement, the device instantly locks the screen, blocking unauthorized access almost immediately. This rapid response can prevent a thief from even gaining initial access to the lock screen.
• Offline Device Lock: Many theft scenarios involve disconnecting the stolen device from networks. Offline Device Lock automatically locks the screen if the device remains disconnected from cellular or Wi-Fi networks for an extended period. This provides protection even when the device is offline, making it harder for thieves to bypass security by simply turning off connectivity.
• Remote Lock: This feature, accessible through Samsung’s “Find My Mobile” service (part of SmartThings Find), allows users to remotely lock their device if it has been lost or stolen. Users can access the SmartThings Find website, sign in with their Samsung account, and then lock the device. This function can also be used to display a custom message on the lock screen with contact information for its return, though caution is advised regarding sharing personal details.

Activating Samsung’s Key Security Features

Samsung has streamlined the process of activating these critical security measures within One UI. Users are encouraged to regularly review their security settings to ensure all protective features are enabled.

To activate the “Theft Protection” features (Identity Check, Security Delay, Theft Detection Lock, Offline Device Lock, Remote Lock):

1. Open the Settings app on your Samsung Galaxy device.
2. Navigate to Security and privacy.
3. Look for the section titled Lost device protection or similar, and then tap on Theft protection.
4. Within this menu, you will find options to enable “Identity Check,” “Security Delay,” “Theft Detection Lock,” and “Offline Device Lock.” Ensure these toggles are switched on.

This acts as a virtual quarantine, protecting against zero-click exploits often delivered through image and media messages. Message Guard is typically enabled by default on newer devices but checking its status under “Security and privacy” is advisable.
• Secure Folder: For those who wish to keep their most personal and sensitive information completely separate, Secure Folder provides an encrypted space on your device. Data, apps, and files moved into Secure Folder are isolated from the main system, requiring a separate authentication (PIN, pattern, password, or biometric) to access. This adds a robust layer of protection for confidential documents, private photos, and sensitive applications. To set up Secure Folder:

• 1. Go to Settings.
  2. Tap on Security and privacy.
  3. Select Secure Folder.
  4. Follow the on-screen prompts to set up your lock type and add files or apps.
