From our observation, iOS users may have trouble enabling their call blocking & identification extension for ScamShield on certain iOS versions. Before you report the issue, please ensure you have carried out the following steps:

  • Updated the ScamShield app version to the latest available version on (ver 4.0.1-1).

  • Tried to re-enable the call blocking setting (even if you have the latest version).

  • Exited and restarted the ScamShield app.

Our team is working on issuing a permanent fix for the call blocking permission issue and we will be rolling out this fix over the next few weeks. If you have submitted feedback, we will be in touch with you as soon as a fix is rolled out.
