I am using it since last year, I didnot face any legging yet, phone is working smoothly. It is a slim phone and it looks good. Picture quality is fine sound quality is also good, xiaomi is giving lots of things within a small price range. If we talk about camera quality outdoor quality of both front and rear cameras is fine, they give better colour reproduction. But in indoor condition cameras quality is not so fine but ok. If we compare the perfornance of this phone with its price then it is a best phone under this price range. The main problem in this phone is that it gets fulty whithin moths, Under buying of three months my phone got fulty, I went yo repair it in service centre of xiaomi in noida sec 63 atta market, and they took too much time the behavior of service provuder was also not good.
