Part 1： preface

Tablet computer, as a digital product between notebook and mobile phone, its existence is an inevitable outcome of the development of science and technology to a certain stage. Due to the large size of the notebook, it is inconvenient to carry and use; However, the size of the mobile phone is too small, and it lacks in viewing and operation; Therefore, tablet computers came into being under this market demand. Notebooks, tablets and mobile phones are combined into three different levels: large, medium and small. They cover the needs of the entire user group for different purposes. Therefore, notebooks, tablets and mobile phones form a tripartite situation at this stage. They can both complement each other and restrict each other. It is the existence of this relationship that makes it difficult for other products to participate in it. Today, we will feel why the tablet computer has such great ability that the user group can't forget it.

As one of the top three brands in the domestic tablet computer industry, Kubi Rubik's Cube has won a good reputation in the market for its low price, high quality and excellent screen display, and has been committed to improving the user experience, pursuing excellence in product design and development, to meet the application needs of different users, and actively promoting the work brought about by cutting-edge digital technology Life innovation. I got to know the cube in 2009. I bought a cube MP4 with my saved living expenses, which is also the first digital product in my life except for my mobile phone. It is also a kind of fate that I am lucky to meet the cube's tablet again several years later. Now let's enjoy the new Freer X9 tablet computer brought by the Cube.

Part 2： Unpacking

The packaging of Kubi Rubik's Cube products has its own characteristics, and the packaging of each product is different. The packaging of the Kubi Rubik's Cube Freer X9 tablet computer is simple and simple. The overall package is a black textured paper box. The middle of the box is branded with the brand of Kubi Rubik's Cube, and the Freer logo appears below.

The white label sticker is located on the top side of the packaging box, which is particularly bright against the overall black background. The label paper shows the model, memory, color, executive standard and relevant QR code of the Kubi Rubik's Cube tablet. The packing box is sealed with two symmetrical transparent plastic stickers with the Kubi Rubik's cube watermark, and the outermost layer is not sealed with plastic film.

The inner part of the packaging box adopts a double-layer design. The top layer is the Kubi Rubik's Cube Freer X9 tablet computer. The tablet is sealed with a plastic bag and the surface of the tablet is also pasted with an original plastic film, which can be used immediately after being lifted. In order to protect the tablet from damage, hard plastic foam is built around the tablet, and more importantly, an outlet is reserved. The lower layer of the panel is a accessory box fixed with cardboard. The accessory box is also equipped with an opening, which makes the experience very intimate.

Finally, let's show the full set of accessories at a glance. Of course, the tablet is the leading role. In addition, there are instructions, warranty cards, quality certificates and a big white cartoon message card that I lost. What I can't accept is that there is no original adapter. What's more, I can't help laughing and crying is that the user manual of the Kobe Rubik's Cube Freer X9 tablet shows the instructions of the Kobe Rubik's Cube iPlay 10 tablet.

Part 3： appearance

The overall size of the Kubi Cube Freer X9 is 228 * 144 * 8.3mm. It uses an 8.9-inch IPS screen with a resolution of 2560 * 1600 and a black frame full glass panel. The weight of the body is about 366g, and the thinnest part of the body is only 7mm. It can be seen that the Kubi Cube Freer X9 is quite thin. There is a 5 megapixel camera at the top of the screen, and there is only a HOME entity button at the bottom of the screen. Unfortunately, there is no fingerprint identification function.

The back of the Kobe Cube Freer X9 is made of all metal body, and aviation grade aluminum is preferred. It has undergone twelve excellent manufacturing processes, such as advanced sand blasting and polishing. In addition, the CN cutting process is used at the junction between the middle frame and the screen to create such a colorful body of the Kobe Cube Freer X9. When the hands touch the metal body, you can clearly hear the crisp friction feeling, and there will be no fingerprints on the back.

There is a 13 million pixel camera on the top of the back. I would like to say a few more words about the camera matching of the Kubi Rubik's Cube Freer X9. In the era of mobile phones with more than 20 million pixels, the matching of the Kubi Rubik's Cube Freer X9 seems a bit shabby. Although it supports auto focus, it seems relatively simple in playing. The camera is organically integrated with the built-in antenna and the metal body, so that the back is not monotonous, and the Kubi Rubik's Cube logo at the bottom plays a finishing role.

In order to ensure the overall beauty and practicality, the Kubi Rubik's Cube Freer X9 adopts CNC trimming and curve transition at the corner of the long side and the middle frame, which makes the whole machine more suitable to hold, and also makes the whole machine more beautiful and fashionable. Two layers of CNC trimming, one layer of metal primary color, and one layer of body primary color. The combination of light and shade makes a sharp contrast between the two. For men, the overall grip is just right, but for girls, it is really difficult to hold 8.9 inches with one hand.

There is a built-in speaker output port and a TF card socket on the top side of the fuselage. The TF card socket supports 128G memory expansion at most, which solves the problem of insufficient memory at the source. There is no key and interface design on the left side of the fuselage, and there are volume+/- keys and power keys on the right side. The first feeling after use is that the key stroke is short, the operation is convenient, and the key feedback is sensitive.

The bottom interface of the fuselage is relatively rich. The figure above shows 3.5mm headphone interface, built-in recording MIC hole, full-featured Type-C interface and built-in speaker output hole in turn. To be honest, it is really unexpected that the Kubi Rubik's Cube Freer X9 platform, as a thousand yuan file, has a Type-C interface. The design of independent stereo cavities on both sides makes the Kubi Rubik's Cube Freer X9 have a distinctive stereo surround sound effect, making watching movies as if you were in the scene.

Part 4： to configure

The Kubi Rubik's Cube Freer X9 uses a 4-core MT8173 CPU from MediaTek. It is equipped with two Cortex-A72 and two Cortex-A53 processing cores. The single core frequency can reach 2GHz. The GPU is equipped with a PowerVR GX6250 chip, which can support 4K video content and online games focusing on image quality. In terms of transportation, storage and storage, the current mainstream 4+64G combination mode of mobile phones is used.

Running points is the simplest and most brutal way to show performance. In order not to bury the conscience of the Kubi Rubik's Cube Freer X9 configuration, two mainstream running points software, Anthare and Master Lu, were used for comprehensive performance testing. Antu Rabbit actually measured 67190 points, Master Lu's comprehensive score was 81857 points, and the experience score was 127.42 points. In terms of the overall running performance, the performance was at the middle and upper level, which corresponded to the overall configuration.

Part 5： screen

The color display of the screen has always been the strength of the Kubi Rubik's Cube. The Kubi Rubik's Cube Freer X9 is equipped with an 8.9-inch 2560 * 1600 resolution high-definition retinal JDI screen that supports OGS touch technology (JDI is the product of the combination of small and medium-sized displays from Sony, Toshiba, and Hitachi). It has the characteristics of low energy consumption, high image quality, and supports 10 point touch. The JDI screen and the powerful GX6250 CPU make every frame of the Cube Freer X9 incomparable.

We can feel the reality above the screen through the live photos. The Kubi Rubik's Cube Freer X9 can show the gorgeous colors incisively and exquisitely. Whether in brightness, contrast, color saturation or analytical power, the Kubi Rubik's Cube Freer X9 can be easily controlled, Through the display screen, all kinds of wonderful image quality are continuously displayed in front of our eyes. The only pity is that the system does not support the function of automatically adjusting the screen brightness.

Part 6： system

The Kubi Rubik's Cube Freer X9 is equipped with the Android 6.0 operating system. The system interface is fresh and simple, which is its biggest highlight. It is also particularly convenient to use. The system has few built-in software and supports self deletion. The software for basic needs is all inclusive. The use of the system is much the same as that of the mobile phone operation. The only advantage is that it is not as complicated as the mobile phone operation and has no excessive functions.

The system information prompt is located on the top. One glide can easily call out the information prompt. The second glide can continue to call out the common settings such as WIFI, Bluetooth, anti color, flight mode, automatic rotation, position information, projection, etc. The most distinctive feature of the Kubi Rubik's Cube Freer X9 is that it not only has a physical HOME key, but also has a virtual key similar to Huawei's mobile phone, which can be easily called out by sliding up at the bottom. The three virtual keys are Back, Home and Multi task Management in turn.

Part 7： use

The tablet is not very demanding in use functions. Its basic functions are shopping, watching videos, listening to music, reading e-books, handling emails, viewing office documents, playing games, etc. Personally, I can't use the tablet to operate other functions except watching videos. Because the Kubi Rubik's Cube Freer X9 supports 4K playback, it is easy to capture videos of 1080p and below, and there is no jam in the whole process (the Internet speed is not good and can't be relied on).

Although playing with the tablet outside can relieve the embarrassment of boredom, the Cube Freer X9 does not support adding a SIM card, so even if you take it with you, it can only be a blind eye. Unless you have downloaded all kinds of movies before going out, or you know that the place you are going to has wifi, or you can open your mobile hotspot for its use. It is strongly recommended that the SIM card slot should be added to future products. For a product, one more function is one more way out.

Children are the happy fruit of every family, but when children cry, it is also called a heart rending. With the Kubi Rubik's Cube Freer X9, it is also a good medicine to put his favorite cartoons on when he is crying, which can instantly attract his attention to it. In addition, the tablet can also play various educational videos and music for children, so that the tablet can accompany children to grow easily.

Part 8： game

The last game outside of work is also a kind of fun in life. It can be easily operated for games like Fight Landlord and Xiaoxiaole, such as Kubi Rubik's Cube Freer X9. For the current large-scale mobile games, there will also be stuck and delayed under multiple tasks, but fortunately, it can be easily controlled under single tasks. It is more enjoyable to play King's Glory with the Cube Freer X9 than with a mobile phone, and you will get a joy every time you win.

Yin Yang Shi is a 3D aestheticism and wind mobile game independently developed by NetEase in 2016. The game is beautiful and ethereal, and has a peaceful artistic conception. At first, there was a doubt about whether the Kubi Rubik's Cube Freer X9 could play this game. When it entered the game, all doubts disappeared. Not only is the whole process smooth and free from any jam, but also the picture quality is very beautiful. During the game, I feel that I am in the midst of it. It is very beautiful.

Part 9： Endurance

The Kubi Rubik's Cube Freer X9 has a 5500 mA lithium battery, which supports the fast charging of 5V-2A. However, the actual experience is a bit disappointing. It takes nearly 5.5 hours to charge from 0 to 100%, and it only takes about two and a half hours for my 5000 mA mobile phone to be fully charged. This shows that the charging speed of the Kubi Rubik's Cube Freer X9 is somewhat inadequate.

In terms of endurance, the performance of the Kubi Rubik's Cube Freer X9 can be said to be satisfactory. According to the measured data of half an hour from six aspects, such as games and video playback, the power consumption of half an hour from games is the largest, and that of half an hour from online shopping is the smallest. After three hours of measured data, the remaining power is 69%. Since the system does not support application recycling, the power consumption is faster if the application is not turned off during standby. As far as daily use is concerned, there is no suspense for one day.

Part 10： dissipate heat

Heat dissipation is also important for flat panels. People will get confused as long as their brains get hot, let alone flat panels. If the tablet brain is hot, it is definitely the rhythm of cards, cards, and cards. In order to make the measured data more realistic, I purposely measured the screen temperature half an hour after the game. At the same time, the measured processor surface screen temperature was 33.4 ℃, which is generally good. If it is hot in summer, the estimated temperature will be higher.

In order to measure the temperature control of the processor under full load, the Kobe Cube Freer X9 was under high load through the pressure test of Anthare. During the 15 minute test, the measured maximum temperature was 40.7 ℃, and the average data was maintained at about 35 ℃. In terms of overall performance, the temperature control measures of Kubi Rubik's Cube Freer X9 are very effective.

Part 11： summary

After many years of encountering again, I didn't expect that Kubi Rubik's Cube had developed into a leader in the domestic tablet industry. This experience of the Kubi Rubik's Cube Freer X9 made me look at Kubi Rubik's Cube again. Although the performance of the Kubi Rubik's Cube Freer X9 is commendable, its overall performance is still worthy of its price of 1299 yuan, or even its cost performance is extremely high. For students and family members, the Kubi Rubik's Cube Free X9 should be excellent. Finally, give some personal suggestions to businesses;

1. Since the entity HOME key is left, fingerprint identification is also integrated into it.

2. Charging is a hard injury. It is recommended to add original adapters and adjust the fast charging mode to solve the user's pain at the root.

3. Add SIM card slot to open the way for going out and avoid the embarrassment of no network availability.

4. The system adds the application recycling function, and the used applications can be automatically recycled in time to ensure a smoother system.

5. The camera configuration is low, and the camera pixels are increased to develop more novel play methods.
