3s prime is a budget phone, for which you need not compromise with style design and awesome features. it runs with 3 GB ram 32 GB rom and snapdragon 430 64 bit processor. and the most interesting thing the battery backup its 4100 mAh marathon battery which is high for this price. it would easily last for one and half to two days in moderate usage. you will be having a hybrid simslot, five inch HD display. the front cam is of 5 megapixels and 13 in back is works great in day light. and it has also got fingerprint scanner which is pretty fast and accurate.
out of my experience it pretty great and worth your money. no heating issues, no hanging, handy devise, stylish metalbody, and you also get other pretty features like compass, ir blaster, proximity sensor, gyroscope cause redmi never compromises in sensors.better than many other phones in market. go for it.;)
