Xiaomi Mi4i was launched in 2015 and have some average hardware configuration but with really awesome camera quality . The camera on this is one of the best its range but the overall performance is really below average .Lots of heating problem , lags mostly . We can’t play high end games on this phone. In summers this phone heats up a lot. Temperature reach to 55°C and under sunlight its stops working due to lots of heating.
As per my opinion don’t buy this phone am facing problems from last 2 years
