As the yureka announce in 2014 December and you can get the phone from January . I was thinking about buying this phone as it was they best at that time in that price . The biggest rival of yureka is xiaomi redmi note 2 4g but the xiaomi is only have bigger battery than yureka and Rs. 1k more than yureka but the yureka is best leaving the battery aside .
Now I am going to share my experience with you . The phone is really awesome, camera is also good and you will get cynaogen if not then you can manually install, yureka is running android 5.1.1(lollipop) and maybe in 30 to 40 days yu roll out they marshmallow for yureka officially . *I am going to attach the camera samples captured with Yureka
