ANR and block statistic

I have 1500 users from whom I receive constant:
1 ANR /day
1 block/day
These values I get from statistics report not detailed reports , I have no data, or details from users .


Should I do something to modify this stat ?
Are you haveing apps with more than 1000 active users without having ANR or crashes ?

I have the impression that they only get sent when the user is connected to the internet.

I received 2 crash reports from users here and the crash counter never updated and is stuck to 1 (crash caused because okHTTP didn't work on 2.2 devices.)

but it should give a crash report where you might be able to figure out what went wrong.
