I am a Youtube Tech Revewer. My sister using this phone for 3 months. Not so good choice. Go for Xiaomi Redmi Note 4.
Performance not so good. I tested this phone by playing Asphalt 8. After some times of playing It starts heating and some times you can see lags on the game.
Build Quality quiet awesome but the mediatek Helio P10 is not much powerful as Snapdragon 625.
3500 mAh battery. That is why the battery back up is not so good.
But in Xiaomi Redmi Note 4, 4000 mAh battery. And the chip, Snapdragon 625, is a balanced chip where you can get Good performance and also good battery back up.
Decent Camera quality.
Sound quality quiet awesome.
