Mac address spoofing without rooting the phone
I want to spoof mac address of my android phone without rooting it.
I have installed 'Busy Box Non Root' and 'Terminal Emulator' in my phone from the play store. Both the apps are working fine (I guess :P) and I can even see my mac address in the 'Terminal Emulator' with the help of command : ip link show wlan0.
However when I am trying to set it to the desired address (mac address of my another android phone), by the command : ip link set wlan0 address xx:xx:xx:xx:xx:xx, I am getting error in my Terminal Emulator as "Operation not Permitted".
Can anyone help me with this error,please?
