I’m currently using this phone redmi 2s.over all its a good phone with a acceptble price range.it has 1GB ram and 8 GB rom.so performancr is pretty good.also no lagging on high gaming or multiple app use.it runs on mui 7 ( upgradble to mui 8 now) which is pretty good and smooth.for me i’m using this phone pretty long time.i got zero complain with the phone.highly recommened .u can also buy the prime version you will get 2GB ram and 16GB rom.but with the price range and performance redmi 2s is best
