Nowadays, people’s requirements for amazing visual experience are getting stronger and stronger. At present, the most common feature in smart phones, everyone can basically say, it is a large screen, and full screen. At present, in the field of smart phones, especially since the beginning of 2020, the flagship products launched by many mobile phone brands are almost all working on various edge screen designs, as if edge screens are to lead the screen design trend in 2020.

So much discussion on screen, lets discuss  the protagonist of today’s evaluation- Xiaomi’s Redmi K30 Pro, the highest-end flagship product of Redmi mobile phones so far. It uses a full-screen design without an edge solution. For one thing, it is worthwhile for us to praise the K30 Pro is not following other brands like sheep. Rather it is focusing on other technical features and creating its own persona.  Right now, it takes a certain amount of courage for mobile phone manufacturers to exist while resisting in making flagship mobile phones without a full-screen edge solution.

As for question why this design in Redmi K30 Pro ?  because the current full-screen solution without edge basically uses a pop-up front camera, the pop-up front camera has a very high technical and design requirement for the stepper motor and transmission design. The elimination of the failure rate of lifting and landing is an important problem to be considered and solved while adding pop-up front camera in phone. Therefore, only mobile phone manufacturers that have the ultimate pursuit of full-screens will risk huge word of mouth drops and insist on using pop-up cameras to achieve full-screens without edge.

Front design: true full screen in pursuit of the ultimate display field of view

The front of the Redmi K30 Pro body uses a 6.67-inch Samsung AMOLED true full screen. The borders on the four sides of the screen are also very narrow. The pop-up front camera design can bring a large screen field of view with a resolution of 2400×1080 and a screen ratio of 20: 9, support DCI-P3 color gamut display, support HDR10 +. The screen uses the latest E3 material, which can achieve higher brightness, lower power consumption, and effectively reduce the blue light of the screen, which helps in eyes-protection.

The peak brightness of this screen is as high as 1200 nits, and it can exhibit 800 nits of brightness under low light for display. With the new local contrast enhancement algorithm, it can maintain excellent readability and visual perception under low light. In addition, Redmi K30 Pro also passed TÜV Rheinland’s Full Care Display Certification, which not only lowers the screen’s blue light and protects the eyes during use, but also provides high-quality screen display effects in multiple scenes.

Touch Screen for GamingRedmi K30 Pro’s screen touch sampling rate is 180Hz, which can greatly reduce the response delay in the process of mobile phone touch. The controls while playing games is more hands-on and smoother, especially in shooting games such as “PUBG Lite”, the advantage of low touch latency is self-evident, maybe the screen touch response is just a few tenths of a second, it gives you a head start in the game and kills your opponents in seconds.

Fingerprint Lock

Redmi K30 Pro uses an ultra-thin screen optical fingerprint module, which is only about 1/10 of the thickness of an ordinary screen fingerprint module. The ultra-thin screen optical fingerprint used by Redmi K30 Pro is directly stacked between the battery and the screen. The phone has more space to put a larger capacity battery (Redmi K30 Pro has a 4700mAh battery), and at the same time, it is placed in a more comfortable area for thumb to reach, making each unlocking movement smoother and smoother. From the perspective of fingerprint recognition speed and fingerprint pressing pressure, the screen fingerprint recognition of the Redmi K30 Pro is fast, but the button strength is also very light, and it is almost unlocked by smallest touch. Hence can be called as very responsive.

At center of the top of the screen, there is a tiny hidden thin strip handset design. In addition, you can’t see any other elements on the front of the Phone frame. However, there is another mystery under the screen of the Redmi K30 Pro. Two light sensors are hidden under the screen. One is a conventional under-screen light sensor that can detect ambient light + screen light. The other light sensor only receives screen light. Combined calculations can eliminate screen light effects and obtain more accurate ambient light intensity. The light sensor on the back of the phone frame can detect the light source on the back of the phone, so that the phone can get a better display even when it is used in backlight. With the cooperation of three light sensors, the screen brightness can be adjusted more intelligently. The direct benefits of this are clearer screen display and better eye protection.

Back design: Oreo four-shot + hyperboloid curved body

Redmi K30 Pro has four colors: Sky Blue, Moon Moon White, Space Gray and Star Ring Purple. The back adopts ultra-precision machining process, and the Fresnel lens texture is carved by high-precision diamond knife.

Among them, the sky blue and moon white are bright in appearance , while the space gray and star ring purple adopt the light and fog AG appearance. The phone frame uses Corning’s fifth-generation Gorilla Glass, which is more wear-resistant and can effectively reduce the probability of breakage when accidentally dropped.

Whether it is the look or feel, it can be regarded as the best when held in hand or seen from distance. The most prominent on the back is the “Oreo” four-camera combination centered above the back, which is a 64-megapixel Sony IMX686 main camera (supporting OIS optical image stabilization) + 13-megapixel ultra-wide-angle lens (with 123 ° super wide field of view) + 800 Megapixel telephoto lens (supports OIS optical image stabilization, supports 3X optical zoom, and up to 30x digital zoom) + 2 million pixel depth of field lens. Below the lens matrix is ​​a flash.

The lower part of the back is the Redmi brand logo. In addition, the back of the phone frame  can be said to be very simple and consistent with the design symmetry,  in line with the aesthetics of Xiaomi. And it should be noted that the back of the Redmi K30 Pro uses a hyperboloid curved body design. The advantage of this is that it gives the phone a very good grip, and also makes the phone more slim when viewed from the side. . The thickness of the phone’s body of 8.9mm is really not a very thick, and the weight of 218g in the hand is not burdensome.

Middle frame design: 20 million pop-up front lens + colorful breathing light effect
