“`
This command lists all network interfaces on the device. Identify the name of the Wi-Fi interface, which typically resembles “wlan0” or “wlo1”.
7. Activate the Interface-Specific MAC Randomization Setting: Enter the following ADB command in your terminal or command prompt, replacing “ with the Wi-Fi interface name you retrieved earlier:
“`
adb shell settings put global wifi__mac_randomization_supported 0
“`
This command turns off MAC randomization at the interface level.
8. Verify the MAC Randomization Setting: To confirm that the setting has been applied correctly, run the following ADB command:
“`
adb shell settings get global wifi__mac_randomization_supported
“`
If properly disabled, this command will return “0”.
9. Restart Wi-Fi: Finally, toggle the Wi-Fi off and on in the Android device’s settings to apply the changes.
Note: It is essential to recognize that disabling MAC randomization may expose users’ devices to potential privacy risks associated with static MAC addresses. Hence, developers must practice due diligence by informing users of this change and obtaining their consent when disabling MAC randomization.
Conclusion
Armed with the knowledge and tools outlined in this comprehensive guide, expert engineers now possess the ability to disable MAC randomization on Android devices. Despite the privacy concerns that may arise, understanding how to control this setting grants engineers the flexibility to develop applications that rely on fixed MAC addresses while maintaining user privacy. So, go forth and harness the power of MAC address identification, all while ensuring a secure and private environment for your users.
