How call protection works

Understand explicit blocking, Safe Call Mode and their different purposes.

Safe Call Mode and blocking are different

Safe Call Mode

When Advanced Safe Call Mode is on, Elder Dialler checks an incoming number against Contacts. It permits a matched Contact and rejects an unmatched, invalid or private number.

Explicitly blocked number

A number deliberately marked as blocked is rejected before the Safe Call Mode check. Blocking remains effective whether Safe Call Mode is on or off.

What Safe Call Mode needs

  1. Elder Dialler must be the default phone app. Android gives the selected phone app control of incoming-call handling.
  2. Advanced access must be available. Without Advanced, Safe Call Mode is treated as off.
  3. Contacts permission must be allowed. Elder Dialler needs access to compare an incoming number with saved Contacts.
  4. Contact numbers must be correct. Review country and area codes when a known contact is unexpectedly rejected.
  5. Become familiar with the behaviour using consenting callers. Try both a saved Contact and a known unsaved number before relying on the setting.

Explicit blocking is managed separately from Safe Call Mode.

Important limitation: Contact matching and blocking cannot identify every scam or spoofed caller. A caller may imitate a trusted number, and phone or network behaviour may vary.

Be advised that Safe Call Mode may reject calls from unsaved health service, emergency worker, neighbour or other legitimate caller not in the Contacts list, although these can easily be added as new contacts from the call history when needed.
