In 2015 Xiaomi launched Mi 4i exclusively on flipkart. I bought it in the same year. In Mi 4i, 16gb internal memory & 2gb RAM is given. But one minus point is that no slot is given for memory card. Sound reception is very good. It is styled & designed in a good manner. It is not quite heavy. Hence, good for use. Camera quality is also a good one with 13mp rear camera & 5mp front camera. Its battery quality is just below par. But nothing to complain on it. In this price range, it comes with good features. Till now I am using this phone since 2015. Xiaomi Mi 4i is having a better value for money.
