RedMi 1S a brilliant phone with upgradable Android version, quard-core 1.6GHz, 1GB RAM, 8GB internal memory and above all less than 7000 rupees. It is hard to get a phone with such specifications. This mobile is worth to buy for uploading or downloading photos/songs/videos which is faster than other mobiles in this range of cost.
The quality of its front and rear camera is really very good(probably Samsung mobiles at this range may not). This is my personal experience.
