How to control android vitals (ANR & Crashes) ?

I already search a lot about android vitals. But couldn’t find any luck.
The reason behind is in most of case the answer is reproduce the anr or crash which I can’t, because in my testing devices it isn’t crashes.

So now how we can tackle this problem as it rises every day. Kindly come up with a valid answer.
Thanks!
