I reviewed the product on my youtube channel. Link: https: //youtu.be/n5_ lB6BvKA0
Personally I prefer this device in this price range. The processor of the xiaomi redmi note 4, snapdragon 625, is quiet balanced chip. That can gives you a balanced form of performance and battery life. Gaming performance pretty good here. Battery back up also good as I said it before.
2.5D curve glass gives you a pretty display experience. Camera quality is better than the note 3. In buttom, don’t think that there is two speaker. There is one speaker on right of micro USB port and the left one is Primary Microphone. In this device, here is no fast charging support. This is little disappointing for me. Also here is no screen protection. So, I hope xiaomi can improve these things on their next devices. But in this price range, personally I prefered this device. You can buy it and definitely you will impress with it. Xiaomi always rocks.
