In a bold move to curb smartphone theft, Google has unveiled a powerful new feature that could render stolen Android devices useless — and unsellable.

With over 25 million phones reportedly stolen in Nigeria in just one year, this development could be a game-changer. The new security tool, called “Theft Detection Lock”, uses artificial intelligence to detect suspicious behaviour, such as someone forcefully taking a phone and running. Once triggered, the phone locks automatically, preventing access or resale.

The feature also includes offline device locking, meaning even if thieves switch off mobile data or Wi-Fi, the phone stays protected. This is a major leap from previous measures that relied heavily on network connection to track or lock stolen devices.

Tech experts and law enforcement officials in Nigeria have hailed the move, saying it could significantly deter phone snatching and organised theft rings that thrive on reselling stolen smartphones.

“The resale value is the primary motivation. If the phone is worthless after theft, the crime loses appeal,” says Ifeanyi Obiora, a Lagos-based cybersecurity analyst.

Google confirmed the feature will roll out later this year, starting with Android 15. It’s expected to make its way to millions of devices, offering hope to users in high-theft regions like Nigeria.

As the nation grapples with phone-related crime, this could be the biggest digital intervention yet.
