micromax mobiles

Hi...
just wondering how micromax is able to produce smart phones with the heavy low price compared to it's big competitors.... What are the trade secret...but quality is very bad as everyone know... but still every one 's ambition to buy a big size screen mobile of micromax which can serve as both tablet and phone together...

Which is the equivalent brand like micromax in US... in big size smart phones..

experts please elaborate your ideas.


thanks
