Blue Devil i9s Pro

One "core" dual-use, two-sided life;
I have used a lot of tablets, all kinds of systems. First of all, what do we buy tablets for? What kind of functions do you want? Many friends bought a tablet because it was fun to see others buy it. Most of them used it to watch movies and play games. Of course, some business people used it to work. In short, the tablet was popular because of the pleasure of experiencing large screen games. The compact body can meet our needs of going out to work, Instead of carrying a heavy laptop, the tablet is divided into several commonly used systems, Apple System, Android System, and Win8 System. Apple System is a closed system, nothing to say, mostly used to play games, watch movies, and show off wealth; In fact, many times it will not bring more sense of superiority. The Android system is mostly used in daily life, and most of the applications on mobile phones on tablets can directly support tablets. Such a popular system naturally has games and applications. More importantly, the transition from mobile phone to tablet does not need to worry about system learning. The disadvantage is that this is just an expanded version of mobile phone. It is not compatible with many applications, so that the office experience is much worse. Win8 is my favorite system. Why. Because sometimes you can continue to work on the tablet on the way home when you haven't finished your work. Win8 system is basically compatible with the daily software on our computer, which is a feature that other systems don't have. Being a business person is really a good choice. The disadvantage is that there are relatively few popular mobile games on some mobile phones, which is extremely uncomfortable with the unstable application stores in China. Would you be surprised if you were given a tablet with entertainment and business functions? Today, let's take a look at Blue Devil, a handheld tablet with one "core" and two functions.

   Before introducing the product, let's get to know the brand of Blue Devil. Blue Devil Digital [1] is a leading design manufacturer of popular tablet computers in China. It was founded in 2001. At the early stage, we first knew that Blue Devil was MP3 Mp4. With the passing of the era of MP3 and MP4 trends, companies like Blue Devil and Oppo later transformed. Blue Devil transformed from MP3 and MP4 products to tablet computers. The difference is that Oppo transformed into mobile phones;

In 2009, Blue Devil was the first in the world to launch a tablet computer product W7 with Android system, which was the first time in the industry to launch the concept of a similar product, earlier than the emergence of the iPad. This belief may have given Blue Devil the courage to persevere. In 2011, Blue Devil released the world's first Android 4.0 tablet. At that time, the author had only been working for two years, and Blue Devil promised to release new products every year until September 2013, when the Intel core tablet of Blue Devil i series was officially released. In 2014, three tablets were released at one go, i7s，i9s、i10s。 The three tablets have different positioning, prices and functions. The i9s is divided into the normal version and the pro version. Today, the author mainly introduces the I9s pro version;

    First, I got this product. From the appearance, it looks like the front and rear glass panels are clamped with a metal shell, and a blue trim edge is clamped at the chamfer. The edge of the glass panel is also chamfered. I can't help liking the craftsmanship. First of all, I was attracted by the appearance of this tablet. The process of i9S is one of the best in China. The i9S seems to understand the voice of most people. There are original films on the front and back, especially on the back panel. If you don't look carefully, you can't see that the film has been pasted. The original membrane is capricious. Ok, let's officially start the formal evaluation of i9s.

If you don't know how attractive a tablet is, you can continue to look:

One "core" for two purposes, two-sided life, Unpacking ：

▲ I9s adheres to the consistent packaging style of Blue Devil. The box packaging has low resistance and cost, which is obviously favored by many manufacturers. Blue Devil is no exception. There is no reason to spend much effort on packaging products priced 1399. The simple packaging has given people a new feeling. Blue Devil still gives Intel quite a lot of advertisements. Who is the first Intel tablet partner in the world? It also shows Blue Devil's spirit of innovation.

▲ The factory film is still carefully pasted. The size is perfect and the hand work is perfect. If the current configuration can be given 90 points, if it is a glass film, I think it will be given 100 points. I don't know whether Blue Devil will save this trouble for users in the future. In short, I look forward to it.

▲ The standard configuration of Blue Devil is also the manual warranty card, charger, data cable, all of which are not equipped with spare parts that may not be used for cost saving. The power adapter adopts 5v 2A output power. Blue Devil uses 8000mAh BYD battery. Eh! Does BYD also make batteries for digital products? I have gained insight.

▲ First of all, there is a familiar button under the glass panel, so this button is a unique sign of the win8 tablet, and the Blue Devil is also equipped with that means that the Blue Devil is a win8 tablet.

▲ It's beautiful. This kind of frame is not a single layer structure, but the effect of several layers of superposition. The buttons are designed in the upper right corner of the front. All metal buttons have good tolerance and fit. The touch feeling of the buttons is particularly comfortable, and the buttons are rounded and chamfered, so no matter how you touch them, they will not feel cut.

▲ The Blue Devil i9s has speakers designed on both sides, which are not easy to block. It has a wider sound range. There are 32 holes on both sides as audio output holes. Watching TV and listening to music can release your ears.

▲ The Blue Devil i9s is equipped with a front 200w and rear 500w lens. Although it is still a little different from many mainstream cameras, it is good that not many people take photos with a tablet. It is enough to record the facts. It is not as comfortable as one sample:

▲ Although the Blue Devil pro version has 64g of memory, it has designed a maximum 128g TF card expansion for users. This is an important role. More importantly, it is because this 8.9-inch tablet has no spare space to design a USB, or that designing a USB in such a small size will disrupt the overall beauty of the entire i9S. Therefore, this card slot also serves as a function to read and copy data.

▲ The process design of the Blue Devil i9s is very beautiful, including that these interfaces are just right, no more, no less, no less, no less. On the left side of the tablet, a Micro HDMI interface, a Micro USB 2.0 interface and a 3.5mm headphone access port are designed. If this is an Android tablet, I think it is a good allocation scheme, but don't forget that i9S also takes into account the Win8 system, so it seems a bit thin according to the traditional interface of the Win8 system. If you want to connect a keyboard and mouse externally, there is no standard USB interface, which can only be realized through the OTG cable, but only one can be connected at the same time, You must also have a splitter, or a keyboard and mouse shared transmitter type to fully support. If feasible, it is suggested that the next generation can take this into consideration in the design. It may be necessary to sacrifice the thickness and beauty of the plate...

▲ Make a small summary of the appearance part: such a design polishing process, double glass design, in my opinion, is the best in China. I can't see any gaps in the panel connection, and the hardness is also a bar. In the interface design, Blue Devil still put the concept of beautiful and thin design first, sacrificing the separate power interface and standard USB interface. At that time, it was a waste of time, The Blue Devil i9S is first of all a handheld tablet, so the choice is different.

One "core" for two purposes, two-sided life, System:

I have used many tablets and Intel chips, but I can't use the Win8 system. I checked later, because some Intel chips are specially designed for Android system, so I can't use one core for two purposes. The i9s uses Intel Atom Z3735F with the highest main frequency of 1.8Ghz. Obviously, this is a relatively cheap CPU. Fortunately, it runs stably, can realize dual systems, and has a good cost performance ratio. Otherwise, the board will cost 2000 yuan. Let's take a look at the charm of dual systems.

▲ The blue magic dual system switching is very convenient and foolproof. Xiaobai can also understand the Chinese prompt in the upper right corner. The volume increases and decreases to confirm the entry. How do you see which system is selected? It is very simple to choose a system whose icon has color. The Blue Devil i9s pro has 64g of memory. The Blue Devil divides it into two parts. Each system allocates 32g of memory. Interestingly, the 32g partition of Android system can be seen intuitively in the win8 system. If the Android part can root, the file information of win8 can also be viewed through file management. It is easy to think about the mutual transfer of files.

Android system

--------------------------

▲ First of all, what will be our impulse to buy an Android tablet? The author also doesn't know the psychology of everyone. At least, the author thinks that if he buys an Android tablet, it is mainly because the screen of his Android phone is not big enough, he is not happy playing games, and watching TV videos is not as happy as the big screen, and then he can easily drop it into the bag and carry it with him. After all, with the growth of Android users, many good game software companies are willing to make a fortune in Android. The benefit must be our users.

▲ Blue Devil made a small change to the Android 4.4.4 native system, optimizing the secondary menu to the primary large icon menu left by everyone. It is true that the mobile phones used today are all based on the Android deeply optimized system, so it is also a necessary trend for Blue Devil to optimize its own tablet system. Today, we see a little progress, and next time, we hope to see a better interactive interface. It is easier to control.

▲ 32g of memory is allocated and 23.5 can be seen except for the system program. Such a large space is relatively undeveloped. There are a lot of things left.

▲ System upgrade. Every time there is a new system package, you will be curious to experience the upgrade. I hope Blue Devil can directly push the ota upgrade in the future.

▲ The score of 33419 is also the real score of this CPU. Fortunately, it runs smoothly. The feeling of experience is not bad.

▲ The Blue Devil has its own application market and game market. Fortunately, the Blue Devil i9s supports gps, which means that as long as we download the offline map, we can also complete the navigation task outdoors. This is a place to add points to the i9s pro.

  ▲ Summary: The experience of the Blue Devil i9s in dual system switching and Android system is very good, and the combination stability of hardware and software is very good. The calorific value is also well controlled, and you can easily play ordinary games. It's a pleasure to add some features of your own to the Android system.

WIN8 system part

--------------------------

If you ask me what is my favorite system? I will not hesitate to say that Windows, facing the computer every day, is familiar with the system, and from time to time wants to do some processing on the shuttle bus on the way to work. However, other systems have no choice about the compatibility of some computer software. The system of Windows 8.1 can just solve this part of my office troubles. If it is a short-term business trip, I can complete the work at hand with a small tablet. So why do I have to carry the heavy laptop? Wouldn't it be better to make room for some other things you can carry with you?

▲ The Win8.1 system of the Blue Devil i9s pro has not been changed, and the storage space of the Android system can be directly accessed from the Win8 system to achieve file sharing. In terms of operation, connecting the keyboard and mouse with the computer is a game. Android system may not be able to control the running points. So under the win8 system, today we will focus on testing the performance and stability of the Blue Devil i9s:

▲ After reaching 56000+points through Master Lu's run, it is really OK to perform under win8.

▲ AIDA64, formerly called EVEREST, is a good tool for professional testing of hardware information and system information. It can detect more information for system hardware than professional hardware detection software such as CPU-Z. It also supports hardware performance testing, which can obtain information such as memory read/write speed, CPU overclock speed, and hard disk read/write speed. The CPU score is 11651, and the frequency is 1583MHz. Office and some small and medium-sized games are completely stress free.

▲ From the data, the maximum write speed of 178MB/s is also very good, 102Mb/s.

▲ Super PI Mod is generally known by those who have played overclocking. Because of its powerful computing function, many people use its computing speed to measure the computing performance of the CPU, as well as the stability of the CPU. It is a tool used by overclocking players to score. The running time of 2.09 million bits is 1 minute and 54 seconds. The computing ability is pretty good.

▲ To summarize win8, Intel chips run more stably on Windows systems, and there is no pressure on multitask optimization. After several score tests, the performance is good. Of course, there are many programs developed based on Windows. Naturally, the win8 system has the advantage. I like to process some small pictures on the computer and install the enterprise version of communication tools to get a perfect transfer on win8. This is a hard truth about liking.

Blue Devil i9s Pro

                                One "core" for two purposes, two-sided life, summary:


Insufficient: There is no separate power interface and no standard USB interface;

advantage: Excellent workmanship, compact, 64g memory, high speed writing, 1900 * 1200 resolution, gps， Dual system, stable performance and affordable price.
Summary: At first sight, Blue Devil i9s pro was attracted by the workmanship. After playing many domestic tablets, they felt that the plastic taste was too strong, or they became trade unions and discounted the price. This time, they really saw the work of Blue Devil's conscience. Of course, the dual system is the place where the Blue Devil i9s pro becomes the main character. I think you can understand that the existence of dual systems is not only a gimmick, but also more gratifying that the switching and operation of dual systems do not affect each other. After several days of experience, the two systems have no problems in the game trial. It can be seen that this board can stand the test of time. If you want to own both Windows and Android systems with high cost performance, the Blue Devil i9s is A good choice  。
