I purchased this mobile from local market at same price.
This mobile is for those people who wants android os applications at lower price point from a branded company like samsung.
Everything works fine.and yes you can play temple run smoothy but subway surfers lags a lot.Disply angle is so good. Volume is also middum.But internet rocks.I decided to have a extra battery to carry.
Final conclusion : -if you are intersted to use facebook, gmail, whatsapp, live, internet surfing.
