[Q] Where are the Radio MAC addresses stored?

Thanks to pr001, I have found the reason that the current batch of custom ROMs do not reconnect to paired BT devices after the phone is rebooted. is empty

It is because the folder root/data/etc/ is empty. In a good environment, their should be a file named bluetooth_btaddr (among others) there. That file is a plain text file which contains the MAC address.

After reading a post in the BlissROM thread there is also an issue where two phones both running the same ROM are causing issues with connecting to a wifi network as both devices have the same wifi MAC address. and with this experience with the BT MAC address I am left with the following questions.

• Aren't the radios MAC addresses fixed to the radio hardware itself?


• If not, how does stock firmware provide unique MAC addresses for the radios?


• If the radio chipsets do have MAC addresses tied to them, how can the devs access them?

Contacts full of redundant addresses

I synced my contacts from an Exchange account (365), but along with all my actual contacts in Outlook it's synced the address of just about everyone I've ever emailed or received an email from.
How the hell is this happening?
It's definitely syncing ONLY Contacts from the Exchange account.

Anyone else get this problem?
