Normally all phones come with English and most of the people here prefer english as their phone language too. But Indian manufactures like Micromax , spice , intex etc make phones with native hindi support ( Without installing third party apps) and advertise it as theit USP (Part of their strategy to target rural population). It is mostly a marketing gimmick since,people who want hindi / other local languages in their samsungs/sony/iphone etc can always have third party keyboards and font support. There are numerous third party local language support apps in play store and istore. But for sailfish may be it makes sense for intex to ensure the os supports local language natively primarily because they are not sure of the enthusiasm of app developers towards sailfish. Intex may be also looking at some consistency across their products ( With all products supporting
local languages) . Companies like intex and micromax use their indian legacy also as a marketing element.
