The "Call Blocker" feature is one of my favorite features in the app, which makes me quite upset to read that you're going to remove it "because of Google Plays new policy".
They've apparently claimed they're going to remove the SMS and Call Log permissions from all apps. (Or rather remove all apps asking for that permission)
The policy clearly states, however, that you can apply for a "permission" to continue to use the Call Log - and SMS.
They wrote this in their reminder from January 14th:
"Developers whose apps used these permissions..." - Call Log and SMS - "...prior to our announcement were notified by email and given 90 days to either remove the permissions, or submit a permissions declaration form to enable further review".
Continuing:
"Developers who submitted a form received a compliance extension until March 9th"
So, are you just giving up on the "Call Blocker" feature, or do you not believe you'll be accepted?
