For many people it might beone of the best phones I have seen in recent times but with its not at all good cause it has so much backdrop. coming to the features with drawbacks xiaomi has only used their name for the company.talking about the camera it is 16 mp rear and 5 mp front but the rear camera is not good as compared to 16 mp and it cannot take low light shots also.
The phone has heating issues also.The phone is available only in flash sales.the last but not the least drawback is you cannot expand the memory either you can use 2 sims without a memory card you can only use 1 sim and memory card.
