On the evening of February 25, Redmi officially released the new flagship K40 series in 2021, including K40, K40 Pro and K40 Pro+. The upgrade focuses on the weight, thickness, double lift, vibration motor and other peripheral configurations, and even IP53. However, this time it is the side fingerprint and plastic middle frame, and the starting price is still the traditional 1999 yuan of Xiaomi/Redmi.
Too long to see the compact version:
Packaged with charging head (ancestral 33W MDY-11-EX) and mobile phone case
The middle punch is really small, but it is decorated with silver rings
High EQ: no breakpoint in the box. Low EQ: plastic middle frame
"Damascus" ink feather plate smooth surface (handsome from the left), white and fantasy (blue and pink) are AG glass
The side fingerprint sounds silly, but one thing to say is that the speed and experience of the physical fingerprint really kill the current screen fingerprint
We specially found the packaging of K30 Pro. Even the K40 Pro, which is not environmentally friendly, is still smaller than the previous year (environmentally friendly). Last year, there were so many sub models of K30 that everyone ridiculed "K30 is a brand new sub brand of Redmi". This year, the huge K40 words on the package seemed to imply something
Three kinds of accessories: transparent silicone shell (shocked! It is the official shell with USB port plug. If you don't like it, you are recommended to cut the plug manually), data cable and 33W old friend fast charger MDY-11-EX (in 3C certification, it is used for all K40 series and Xiaomi 10 of Snapdragon 870 version).
The front is also changed to a center punch like the Redmi Note 9 Pro, with the camera aperture of 2.76mm, and the official announcement is "almost the smallest screen punch". However, it is rare to make a small hole, but the silver ring decoration is added to highlight the existence of the camera (the reflection from the side will be seen, but it is black at the front). The operation is a bit confusing. The left slot of the micro slot earpiece is directly connected to the top speaker, while the function below the right micro slot is unknown.

This time, all K40 series are Samsung E4 straight screens with factory calibration, delta E≈0.35， DisplayMate A+rating. 120Hz refresh rate+360Hz touch sampling, official announcement of the first super resolution touch (touch zone increased 8 times from 2400 * 1080 to 19200 * 8640), with ambient light sensor and Xiaomi version of "True Tone True Color Display".
This generation of K40 has a breakpoint free design side frame (in this era, as long as you see the middle frame without antenna partition strip, you can basically confirm that it is made of plastic. However, the price should not be too much). There is a whole circle of plastic washer at the edge of the screen. The washer is high, but fortunately the edge transition is smooth, and the feel is OK.
Among the six symmetrical openings on the top frame, the far left side is actually an infrared transmitter. Although the speaker does not have Dolby's belief standard, it is also Dolby's joint tuning. In fact, it is certainly not as good as the Xiaomi 10 Pro music phone, but it is also above the average level.
This ink feather color matching is inspired by the Damascus steel knife. The grain is mainly concentrated in the upper right corner. When viewed from the left side, the grain effect will be more dramatic.
The camera matrix is a "2+1" structure, with 800W pixels of ultra wide angle and microphones symmetrically placed (sad for ultra wide angle enthusiasts). This new family design is indeed more beautiful and harmonious in K40.

But some people prefer white and Mirage (blue and purple) because they are AG glass, regardless of its color and pattern, "AG glass yyds!"
The most special feature of K40 is the raised side fingerprint button. The button has its own radian, which is slightly different from the volume button. The pressing feel is not as good as the volume button.
At the beginning, I was also very puzzled about why screen A still had side fingerprints. In the end, he was overcome by the unlocking speed of the physical fingerprint, "What joy is the fingerprint under the screen!". Tap to unlock (don't really press it down). Tap twice to trigger shortcut operations (can be customized as screenshot, notification center, voice assistant, payment code, scan, camera, flashlight, etc.).
