I'm using Android 6.0 (non-rooted) phone and looking for an application called
call tools optinno.
Though it can be easily found by searching on net : https://play.google.com/store/apps/details?id=com.calltoolsoptinno , However, I can't find on play store by searching
call tools optinno or by
call blocker etc.
I've also tried by entering id :
com.calltoolsoptinno on the play store but didn't get.
Note: I've scrolled down multiple times but can't find the app I'm looking for.
What's wrong with searching mechanism?
