The Redmi Note 5 Pro is one of the best phones I have ever encountered . The camera is really awesome it comes with a 12MP+5MP dual real camera and a 20 MP front facing camera with portrait mode and is truly called the Camera Beast.
It runs on Snapdragon 636Soc which provides awesome speed. Not to mention, the MIUI(9.2. out of the box) provides an awesome experience which truly adds to the performance of the phone. According to me 4GB of ram is more than enough to run all the program on any normal phone until you are not a super busy person(You know what I mean right.).
The face detection feature works quite well and needs the brightness to be adjusted to maximum to work in complete darkness also the fingerprint sensor is super fast.Overall it’s a very good phone and is good value for money.
