I purchased this Xiaomi Rdemi 3S Prime about one months ago.my personal experience with mi 3s prime is very bad. its primary camera comes with 13megapixel and secondary camera is 5 megapixel.but in reality its 13 megapixel camera looks like a 5 megapixel.its front camera is little bit good.if u r a style and design lover u can buy it because its design is ultimate.its sound is very low u can use your multimedia by ear phone.but u have to buy ear phone separately because mi does not give ear phone with this any phone.it has a good features it comes with 3gb ram and 32gb rom. its plus point is battery which is 4100 mah.u can use it continue 24 hours on video streaming.
