Android P gets stricter call blocking

XDA-Developers reporting that Android P might get a new feature to the stock dialer app  commits showing a part of a new set of a new patch-set that were added to AOSP from a Sony Engineer. This little new feature would allow you to block all incoming calls from any number that isn’t in your list of contacts. Text strings found in the commits suggest there will be option to block numbers based on the following criteria.


Feature overview

The following features/abilities are possible with the new commit in Android P.

  • Phone number not in contacts list
  • Phone number not disclosed by the caller (Private number)
  • Phone number is from a pay phone
  • Phone number does not have any caller ID information
  • Emergency Calls disable this feature
  • Associated with a pay phone



XDA also points out that it appears carriers could disable this new call-blocking feature. They may do this to sell you their add-on monthly services instead.

Please keep in mind

These commits aren’t merged with AOSP yet, though a software engineer at Google commented: “I’m very much in favor of this change as a whole; its a nice improvement to call blocking, especially being able to block unknown numbers.” While this doesn’t address the maddening rise in spoofing, this preemptive call blocking would be a welcome feature in Android P for most users.

Final Words

There’s no guarantee that Google will add this into Android P, but it is a possibility. The proposed call blocking features for Android P are truly wonderful value additions the step is a really huge one. Te problem with external applications are trust, they might steal your call history among other information, using too many resources or drain your battery because they (same like the dialer) need to run all the time in the background.

Personally I would liked to see some additional features which ATM, are offered solely by top-of-the-line call blockers:

  • Ability to block a set of numbers, by Groups
  • Ability to block on the basis of wildcards
  • Ability to schedule blocking on multiple timelines
  • Ability to maintain global exception lists — whitelist as well as blacklist
  • Ability to use differential blocking such as (ignore,) (reject,) (kill,) (answer + hang-up,) (answer + wait + hang-up,) (answer + hold,) (offline)
  • Ability to override global exception lists
  • Ability to notify selective events
  • Ability to log selective events
  • Ability to block messages without hijacking the messaging association
  • Ability to block messages based on content
  • Ability to auto-reply via different custom text messages, upon blocking selective numbers

Some exquisite features on my personal wishlist:

  • Call blocking with inbuilt voicemail (like the one on the Symbian platform)
  • Call blocking supporting VoIP
  • Call blocking supporting VoLTE
  • Call blocking supporting EM

Inclusion of the additional features described above would’ve made it a quantum leap but the new change which Android P gets is also not bad, I mean every little step forward helps.


  • Android P May Support Blocking Calls From Unknown, Private, and Pay Phone Numbers (

  • Android P may introduce stricter call blocking (
