If you liked Redmi K30's design, you are going to love K40. it's a much more refined model than its predecessor. It weighs only 196g. From the rear side, the design of K40 is almost the same as Mi 11 design. The camera module is elongated and camera sensors are distributed more evenly.
The fancy gradient back cover and camera placement overall make the rear side of the phone more clean and elegant. The red and blue gradient color is the primary color of the K40 where it refracts blue and red in different lights. Many people are going to love this fancy gradient.

The screen has an adaptive color display which was found in iPhone. It adjusts the screen's color temperature to the color temperature of the ambient light that helps to reduce eye strain.
Given the price tag, we are not expecting too much from the photography section. K40's primary camera doesn't have any optical image stabilizlation. The ultra-wide camera is 8MP and there is a 5MP telephoto macro lens of the same type as the Mi 11. In real life, the K40's main camera take slightly over-exposed photos.
