In my opinion moto g5 plus is the best phone under 17000. It has back camera of 12 mega pixel but It has 4k video recording with 2160 fps. This device has 5.2 HD display with snapdragon 625 octacore processor. The pixel density of this device is very good. It has a battery capacity of 3000mAh. It have a finger print censor. It is very user friendly and the screen is so good.
The front camera is 5MB but it gives us a great experience. It has a ram of 4GB and rom of 32GB. It is androis version is nougat. So I recommend you to buy Motorola Moto G Plus 32GB to others.
