What kind of bots go to the application?

Question

Android

The application has a standard android control for setting the rating (asterisks). I began to collect statistics of clicks, and it was not clear what came out. The distribution of ratings is almost uniform and quite wonderful in terms of the time of clicks from the time the application was installed. For example,

Rate: 5 stars; time after install: 0 days, 18 hours, 36 minutes, 35 seconds
Rate: 1 stars; time after install: 0 days, 18 hours, 36 minutes, 39 seconds
Rate: 2 stars; time after install: 0 days, 18 hours, 36 minutes, 48 seconds
Rate: 1 stars; time after install: 0 days, 18 hours, 36 minutes, 49 seconds

Rate: 2 stars; time after install: 0 days, 0 hours, 4 minutes, 21 seconds
Rate: 1 stars; time after install: 0 days, 0 hours, 4 minutes, 23 seconds
Rate: 2 stars; time after install: 0 days, 0 hours, 4 minutes, 25 seconds
Rate: 1 stars; time after install: 0 days, 0 hours, 4 minutes, 26 seconds
Rate: 3 stars; time after install: 0 days, 0 hours, 4 minutes, 29 seconds
Rate: 4 stars; time after install: 0 days, 0 hours, 4 minutes, 29 seconds
Rate: 5 stars; time after install: 0 days, 0 hours, 4 minutes, 30 seconds
Rate: 3 stars; time after install: 0 days, 0 hours, 4 minutes, 34 seconds
Rate: 1 stars; time after install: 0 days, 0 hours, 4 minutes, 35 seconds
Rate: 4 stars; time after install: 0 days, 0 hours, 4 minutes, 36 seconds
Rate: 1 stars; time after install: 0 days, 0 hours, 4 minutes, 40 seconds

At other times, the rating button is practically not pressed. The application installs 40-60 new users per day. The real rating in the play is completely different.
These are statistics of the release version, not beta, which are automatically tested by bots in the console. And the bots in the console do not click on the asterisks. Hence the question: what are these bots?
