Well, you recommended using iPhone or iPad ($1000- $2000 in India) I do use an Android phone for $300. And, well, I do not plan to buy a phone for $1000 because it doesn't make sense (the production cost of the iPhone would be around $50).
Having in mind that India is one of the largest providers of available social media services, and they can use your app for business if you market it right, you leaving millions of dollars on the table.
Consider improving your app for such phones like Mi, Asus, Micromax, other low price range phones based on Android. (BTW, most of your competitor's apps are working perfectly well on my phone, they do know the market advantage already)
