Android security tools function by limiting your apps’ access to your device’s IMEI, serial number, and other identifying information. It also gives you a little more protection when using Wi-Fi networks by randomizing your device’s MAC (media access control) address.
If you use your device for business, your organization might require the Wi-Fi MAC address of your device in order to make a wireless connection. The Wi-Fi privacy settings use randomized MAC addresses by default, so you will need to manually change this to “Use device MAC” by following the steps below:
Wi-Fi with password lock
Touch “Settings”.
Touch “Wi-Fi”.
Touch the Wi-Fi name to enter the password input interface.
Touch “Advanced options”.
Touch “Use randomized MAC” under privacy, then touch “Use device MAC” in the pop-up menu.
Then input the correct password to connect Wi-Fi.
Wi-Fi without password
Touch “Settings”.
Touch “Wi-Fi”.
Touch the Wi-Fi name to save the Wi-Fi.
Touch the setting icon beside Wi-Fi name with Saved status in the list.
Touch “Privacy”.
Touch “Use device MAC” in the pop-up menu
Note: Available settings and menus may vary depending on device model and software version.
