Oneplus company makes awesome phones and are also very cheap.
To get the same configuration as one plus 3 you have to pay almost 60000 to buy a Samsung phone.
This phone has the best fingerprint sensor I have used in any device. Just a blink of an eye and done. Also with 6gb of ram you can handle everything on this device from high end gaming to full multitasking. I personally think this is the best phone one can buy at this price.
