Dear friend, if you do a lot of multitasking and want to store a lot of data on your mobile, then you should definitely opt for 3gb ram and 32 gg of rom configuration. if not, then you can opt for the lower configuration i.e. redmi 3s. I hope this post helped you to take the right decision in making a choice between the two configurations of phones available. On mi.com and flipkart and price is only 8999 so best of luck
