Redmi 3S Prime is a good phone comparing to its price and other phones at its price but the phone is a late comer. Why I am telling this a late comer because compared to the price which is 9000 rs. so much companies give good phones for this price like Coolpad which is launched Coolpad Note 3 for 9000 rupees its a very good phone at the launch time because its gives a 3 GB of RAM, Fingerprint Sensor, 16GB of Internal Storage and remaining common specifications. When we compare this with specifications with Redmi 3S Prime. It is an upgraded version of phones like Coolpad Note 3 like giving you a 32 GB of internal storage and some minimal improvements. At that launch time of Coolpad Note 3 it is a successor for 9000 rupees the people who want 3 GB of RAM, Fingerprint Sensor for 9000 rupees the people only buy Coolpad Note 3 but if Xioami launches its Redmi 3S Prime at that time it will be the most successful phone in 9000 rupees so its a pretty late comer but the people who want 3 GB of RAM, 32 GB of Internal Storage, Fingerprint Sensor can buy this phone by ignoring Coolpad Note 3.
