WWDC 2016 slides Phone spam call

If you’ve tried any of the call blockers, or spam identifiers in iOS 10, you’ve surely been disappointed. I’ve tested out a number of them and they really haven’t seemed to do anything at all. Most of the time not blocking, or even identifying calls. It appears we may now know why.

It looks to be an underlying issue with CallKit, Apple’s new framework that powers these types of apps.

It seems to have been a serious enough issue that Apple has reached out to some developers to let them know that they have stopped processing reviews of apps that block calls into the App Store until iOS 10.1 is released, possibly later this month.

According to Rocketship Apps, the developer behind CallBlock, they say:

We’ve now had a call with Apple’s app-review team and have an explanation for both. They let us know call-directory extensions, of which Callblock is one, are failing intermittently due to issues with CallKit, which is the new iOS framework Callblock uses to screen calls. The issues are expected to be resolved in iOS 10.1 and they’ve paused reviews of these extensions till 10.1 is publicly available.

Hopefully, once iOS 10.1 is released, we will start to see call blockers back on the App Store with much improved performance.

    Probably, iOS 10.1 will release on the week of October 23. Just saying!

  • Gabriel Anaya

    That would explain some things. I would expect the 10.1 update to drop by mid-november at the very latest.

    I’ve noticed that numbers can be blocked on my iPhone but my Apple Watch still rings :/

    Cannot get past Settings > Phone > Call Blocking & Identification. iOS 10.2.1

    Any ideas? Hiya, Mr. Number and Truecaller all want me to go there and “enable” them, but I’ve been unable to do so.

    I sent a support email to Hiya via the app. The Hiya website does not have a support link.
