Call Blocker Customer Insights

1. Very much useful.💐I've been using this app about a year.. It certainly does block any n all calls from those who are Not on your Contact List!! Which is a blessing when it comes to the#s of telemarketing and scammers however I have yet to figure out how to allow the calls through that I may be in need of.

2. Don't even know if there's a pay-for version, but would consider it as a way of supporting quality work.I had been using Android's Do Not Disturb mode to block non-contact-list callers (while allowing everything else).

3. Update below! This app is great! works really well! I'm so glad I found an app that actually does what it says it does! Update: After using it for a while I still like it for the most part, but I dont like the setting that says it'll pick up and hang up softly, no voicemail.

4. *FYI..it you go into Settings: Allows you 3-4 choices regarding Answer"n the phone!! Total Block/no ring, Ring once the hang up w/no voicemail, I can't remember the final option but they do have options.

5. The Call Blocker app restores my ability to block spam calls while keeping full watch functionality.

6. (Edit: turns out there's an option in the Gear Wearable app to turn off the DND sync, so Call Blocker isn't needed for that purpose.

7. But a recent Gear S3 update forces the watch to be in DND mode whenever the phone is, which turns off many of the watch's important features.

8. Selecting contacts for white list is very difficult.have to individually choose each contact and the list started from the beginning each time.

9. It does not block calls and I cannot erase the calls any longer.

10. Plus I can now reconfigure the phone's DND to stop all kinds of interruptions at selected times, instead of having it always enabled solely to block spammers.

11. If I am expecting a call from someone not in my list I can disable it and then restore the blocker when my call is complete.
