Thanks, James! Doesn’t the MAC address situation kind of depend on the actual ROM? For example this StackOverflow post (https://stackoverflow.com/questions/33159224/getting-mac-address-in-android-6-0) lists at least a couple of workarounds with other APIs, although I was told, that for example for Samsung devices they don’t really work.
As for the IMEI access, could you maybe provide us with a screenshot of such permission request? I’d love to update the article with it.
