The major thing misssing in the redmi 3s prime is the great ram management which was available in the redmi 3s.The camera performance of the redmi 3s prime was a bit satisfied the low light shots were a bit washed out.The phone did heat while using the camera app.The redmi 3s prime uses a hybrid sim slot which means it accepts one micro sim and one nano sim or one micro sd card for storage, unfortunately this means we have to choose between second sim or micro sd.
