Smartphone thefts continue to increase, especially in major cities. In an attempt to curb this phenomenon, Samsung is relying on technology. The brand is currently rolling out One UI 7, a software update incorporating several new features designed to better secure Galaxy devices—with or without an internet connection.
Fighting Smartphone Theft
Among the new features is Offline Lock, which automatically blocks access to the phone if it remains offline for too long. Another option, Remote Lock, allows you to regain control of the stolen device simply by entering your phone number and a quick verification.
Samsung is also integrating artificial intelligence to detect sudden movements associated with snatching. If such a movement is detected, the screen locks immediately. The interface also offers a protection called "Identity Check": in an unusual location, biometric authentication becomes mandatory for any attempt to modify sensitive settings.
Another important new feature: a one-hour security period is imposed if a person attempts to reset biometric data. This period of time can allow the legitimate user to block the device remotely from another connected device.
These functions are available on recent Galaxy phones: from the S22 to the S25, including the Z Flip 5/6 and Z Fold 5/6. To activate them, go to Settings > Security and privacy > Lost device protection.
The brand is also relying on its Samsung Knox platform to strengthen confidentiality. In addition to theft detection and smart locking, users can also track their device in real time, remotely wipe it, or extend its battery life to facilitate recovery. "We are in constant contact with the authorities to advance the fight against phone theft," says Annika Bizon, head of mobile marketing at Samsung UK. Finally, Samsung offers practical guides on its site for responding to theft: how to activate lost mode, erase data, or change passwords remotely. Additional options allow users to find connected devices like Galaxy watches or earphones via the Galaxy Wearable app. The initiative is not limited to technology: it also relies on user accountability. Because for these protections to be effective, they still need to be activated!
