The only model researchers found to do randomization correctly was the Cat S60
Amusingly enough, that's probably more because of an oversight by the manufacturer (who is probably just copying a reference design) --- they don't bother writing a "fixed MAC" and just leave the NVRAM blank, meaning the device doesn't actually have a MAC and generates a random one every time you turn WiFi on and off.
That's how it works on the Mediatek platforms that I'm more familiar with, and you'll find this is the case for a lot of the cheap Chinese unbranded phones. It's irritating when you need to connect to networks using MAC filtering, but I'm almost tempted to respond to all the "my MAC keeps changing" threads on XDA with "that's a feature, not a bug." ;-)
