I am using Redmi 3s prime and all I can say is this is the best phone.The camera quality, battery backup, Internal storage every thing is perfect!.
It is very slim and light in weight.The golden colour in this phone looks really very classy.I personally recommend to get it if you are in a plan to get the new phone. Even if I connect 2 to 3 devices through my hotspot, the battery works for around 8-10 hours.
the camera is good.We dont need to use the additional application to get the perfect pictures.
