After I updated my Lumia 640 to Windows 10 Call + SMS filter app was removed and should have been replaced by new Block and Filter feature. But I'm not able to find it on my phone. I'we already looked in settings, applications and on app Store, it isn't there. But it is, actually, listed in Settings -> Privacy -> Background apps. So, in theory, it is running but I can't open it's user interface.


To open Block and Filter go to Settings->Extras->Block and Filter.If this is not working for you, there is a workaround as described here,

However, due to some weird reason the app keeps crashing on my phone, when opened through Extras. So, I found out another way to open the app, tap on Phone> Click the three dots below> Click on Blocked calls.

Here are the step by step instructions,

  1. Open the phone app, click on the three dots.

You can also block and unblock calls without navigating into the app. Refer this article for details.

  • Before any of these ideas work you have to go to the setting to select Apps for Blocking Calls" and select Block and Filter. Until you do this call blocking options are all hidden. Dec 9 '17 at 13:15

I can suggest you another way go to Phone App click options(...) button it will show options click Blocked Calls and you are there.
