Google has introduced a comprehensive suite of security features to protect Android users from phone theft and safeguard their data.

These improvements, which leverage advanced technologies like AI and biometric authentication, are now available globally on Android 15 and devices running Android 10+ via a Google Play Services update.

The cornerstone of these security updates is Theft Detection Lock, an AI-powered feature designed to secure your device in the event of theft.

This feature uses on-device machine learning to analyze signals, such as suspicious tampering, and automatically locks the screen if a theft attempt is detected.

How the features work

Rolling out gradually, Google said the feature would initially cover Android devices used by 90% of active users worldwide. Users can check their theft protection settings to see if their device is supported.

• According to Google, offline device lock activates when a thief takes the phone offline to bypass wiping or remote tracking.

• The device automatically locks the screen during extended offline periods, preventing unauthorized access.

• Remote Lock allows users to quickly secure their device through any internet-connected device. Even without Google account credentials, users can lock their phone by visiting Android.com/lock and entering a verified phone number.

• This feature integrates with Find My Device, allowing users to remotely locate, secure, or wipe their devices.

• Google also emphasizes the importance of regularly backing up data to minimize losses during remote wipes.

Enhanced security for preventative measures

Google said sensitive settings like Find My Device now require authentication via PIN, password or biometric data.

• Multiple failed login attempts trigger a device lock, thwarting password guessing attempts.
• Factory reset protection makes it more difficult for thieves to reset a stolen device without the original Google account credentials, significantly reducing its resale value.

Google plans to launch an additional feature, Identity Check, later this year. This opt-in tool will require biometric authentication to access critical settings, providing another layer of protection even if a thief compromises the device’s PIN.

What you need to know

Phone theft remains a pressing problem in many regions, including sub-Saharan Africa, where smartphone adoption is rapidly increasing.

• According to the GSMA Consumer Survey 2023, 19% of mobile phone users in South Africa have experienced theft or loss of their device in the past year.
• Similar trends were observed in Kenya (61% adoption), Uganda (31%) as well as Rwanda and Burundi (24-25%), highlighting the urgent need for effective security solutions.

Stolen phones attract criminals due to their resale value and sensitive data, which can result in significant financial and personal consequences for victims.
