I have a free Android app on Google Play that uses Google Analytics to gather statistical data about the usage. Recently I noticed that the number of new users from India (and countries from that region in general) increased quite rapidly. However, I can see these new users only in Analytics reports - Google Play statistics are showing only about 1/6 of the users I see in Analytics. Unfortunately I am not able to find out, what is the source of the new installs.
I wonder if there are some popular alternative application stores in India, where my app could possibly be placed without my knowledge? Have somebody experienced something similar?
