I am using Xiaomi Redmi 3S as my secondary phone for about 3 years and satisfied according to price and features it provides.I have 2GB 16GB varient and it works finely.But a after the new updates it lags and heats so much but today also it works nicely.
It is available in two varients
2GB 16GB at 6, 999
3GB 32GB at 8, 999
Overall it is very good phone according to price.
