Android P to stop telemarketers?
But relief from unwanted calls is on the way, according to XDA. The latter says that a number of new commits has hit AOSP thanks to a Sony engineer. One of the commits mentions how users will be able to block calls from unknown numbers, private numbers, pay phones and from any number not listed in their contacts list. Called the "enhanced call blocking feature," this should allow users to block telemarketers from interrupting their busy schedule (or their schedule for getting busy). Currently, you can block calls from specific numbers only, and that has to be done after the initial call.
XDA also says that Android P just might feature native Iris scanner support and the ability to block cameras and microphones from being accessed by unused apps. Activity has been slowing down in AOSP which suggests that the first Android P developer preview could be released soon.
