'ifconfig wlan0 hw ether' is working well on my Linux laptop.

But it does not work at all with any of my (many) Android devices. I
usually see "SIOCSIFHWADDR: operation not supported" and I am unable to
connect to any AP until I reboot and try again with the original MAC
address.

Has anybody ever successfully changed the MAC of, say, a Galaxy Nexus
device?
