This mobile as two things extra on redmi 1s is
1) 64bit processor
2) 300mAh extra battery
So why should anyone buy but if you want to buy it is fullfill your needs if you just need to use some amount of apps and games.
Camera quality is excellent. And also battery is good. Screen quality is quite excellent. All other features are great response is good.
What I like most in this phone is regular updates. Yes it is recently updated to miui 8. Overall experience is great and this device is great.
