Mi is best known for its wonderful products world wide and this mobile really tells us the story of mi. We are talking about mi 4i and really it is very wonderful mobile in its price segment. It has 5 inch full hd display, having 16gb/ 32gb internal memory and having 13 mp rear sony/samsung camera and having 5mp front camera. Having non removable 3120 mAh battery and a hybrid sim slot.
Battery and camera of this mobile is great and it is overall a very wonderful device. Also its is very light in weight and having octacore cpu and performs excellent in all conditions. It is available in two variants 16gb and 32 gb variants. As with hybrid sim slot so as per my thoughts u might be go with 32gb variant. In the end I found this mobile is excellent for day to day usage.
