★★★★★
Fantastic app that DOES block calls!! Note that NO call blocker has the
hang up feature for android above kitkat 4.4.1!!! That is Google's fault!!!
This is best call blocking app ever and it DOES work!! The pick up/hang up
feature ONLY works on Android Kitkat 4.4.2 or below--this is an Android
issue and is true for ANY call blocking app! NEGATIVE REVIEWS ARE BECAUSE
FOLKS DON'T READ DIRECTIONS that are within app (top of each page)! Yes you
can customize the block list!! I've tried many including one that costs $20
and this one DOES work. For android ABOVE kitkat, blocked calls do go to VM
and this is true for ANY blocking app. Quit blaming the developer for
Android issues or for not understanding the app. I am a user and not
affiliated with this app.
★★★★★
Love the option of being able to have only phone numbers in my contacts
being able to ring my phone an all others are sent to voicemail.
★★☆☆☆
The blocked number still go to voicemail and show a missed call. Not
working for me. Waisted my money.
★★☆☆☆
Suddenly it no longer hangs up. Sends unwanted calls to voicemail even
though it's set to hang up. Mail to developer is returning by Gmail
undeliverable.
★★☆☆☆
This app used to work great but somethings changed. The option to block with no voicemail has stopped working. No support, email and developer website no longer exist. Don't pay for this app without checking first and the developer Grey Thinker responds.
