I have always wanted a tablet that can make calls. The price difference between the ordinary talkable tablet and the non talkable wifi version is quite large under the same configuration, which also worries users who buy the tablet. With so much money, is it meaningful to add a call function? I also had this idea myself. This time I had the opportunity to experience the 7-Rainbow G708 3G 8-core phone version. To be honest, the price of the 7-Rainbow G708 seems to be only 399. At this price point, the MTK6592 processor and 720p resolution screen are used. Even at the same price point, non call boards almost have no such performance. Seeing this price point and this configuration, I really don't believe it, If I can tell which mobile phone or tablet with the highest cost performance ratio I have seen from 2014 to 2015, I think it must be the seven rainbow G708 3G eight core version. Not much else. Here's my actual experience of the Seven Rainbow G708 3G 8-core phone version to understand how this tablet actually works. The first is the appearance of the Seven Rainbows G708 and its simple hands-on experience.

▲ Packaging and accessories: The appearance of many series of Seven Rainbow tablets seems to be the same. They all use this simple gift box packaging. I can hardly find any information except the brand information on the front. I don't know how Seven Rainbow distinguishes tablet models. Anyway, I can't see any model information from the packaging, And the packaging is exactly the same as the E708 I used to play. I think it's easy to confuse. It is not only easy for manufacturers to confuse, but also possible for users to confuse. They hope that some information such as model can be added on the package for differentiation.

The accessories of the Seven Rainbow G708 are really too simple. Compared with ordinary tablet accessories, there are mainly fewer charging heads. It seems that the main problem is to control the cost. Fortunately, the charging head of the Seven Rainbow G708 is universal with ordinary Android phones, and charging is not a problem. Given the low price of the Seven Rainbow G708, this is acceptable. After all, it is about 30 yuan to buy a charging head alone.

▲ Appearance: The Seven Rainbow G708 is mainly a mixture of white and cyan. The appearance is generally ordinary, not particularly beautiful, but not very ugly. The appearance of the tablet is rarely very ugly. Since the emergence of the iPad, almost all tablets have some shadow of the iPad. The front of the Seven Rainbow G708 looks a bit like a Samsung phone tablet, with rounded corners, white front frame and microphone sensor. Although the price should not be too high, I still suggest that the front frame should be narrower so that it is more convenient to hold and looks better. Nowadays, both mobile phones and tablets pay attention to the proportion of screens. The higher the proportion of screens, the more beautiful the mobile tablet looks. In fact, I also pay attention to the G808 calling tablet of Qihonghong, The screen percentage of G808 is ideal.

As a seven inch tablet, the Seven Rainbow G708 can only be barely taken down with one hand, but it is basically impossible to operate. The tablet still needs two hands to control. It is also because of the large screen that it is easier to play as a tablet. Although the operation requires two hands, if you make a phone call with someone, you can use one hand to make a phone call, provided that your hand is about the same size as mine.

Seven Rainbow G708 is distributed with sensors, phone earphones and front 300000 pixel camera on the top of the front. Some people may complain about the significance of 30W pixel front camera, which I think is very useful. For example, when you chat with QQ video, you won't hold the back camera against yourself, so the front 30W camera is good for online video chat, It's OK to see people clearly, but it's not necessary to have high pixels. I think the design of the tablet with earpiece is the real tablet. Sometimes I see some tablets without earpiece design. I use earphones to make and answer calls. This design really makes me drunk. If I want to make calls, I have to carry earphones with me. It's troublesome to think about it. Although the price of the Seven Rainbow G708 is not high, it still has a earpiece designed, It gives users great convenience in use. At the bottom of the front is the English LOGO of Seven Rainbows. On the whole, the front design of Seven Rainbows G708 is simple.

As for keys, the keys of the Seven Rainbow G708 are all distributed on the right side of the tablet, while the headset slot and USB data slot are on the top side of the tablet. At the bottom of the panel is a polar microphone hole. The design of keys and hole slots is relatively conventional, the feedback feel of keys is moderate, and there is no sense of looseness when shaking around keys. The workmanship is good.

As a cross-border product with communication function, the Seven Rainbow G708 also has a network access license. The Seven Rainbow G708 network access license is on the back of the tablet and pasted on the plastic sticker on the back of the tablet. It is recommended that new users tear off the sticker and save it for emergencies, because some information such as network access license is required for equipment warranty, I'm not sure whether Seven Rainbows is good or not. Anyway, it's right to keep it well.

There is a 200W camera on the back of the Seven Rainbow G708. It doesn't seem to support auto focus. This camera is meaningless to me. I don't know if anyone needs this camera. Of course, it is better than nothing. At the same time, the speaker on the upper right corner of the back is shown below, and the model memory and other information are shown. The back of the Seven Rainbow G708 seems to have undergone some texture processing. From my personal perspective, the texture is not beautiful, but it feels better than the smooth back. The friction of the touch is greater when you master the tablet conversation with one hand, and it is not easy to slip off.

Seven Rainbow G708 is a call tablet. There is a small gap on the right side of the top of the back, which can easily open the top rear cover. After opening, you can insert a micro sim card and a tf expansion card. The network system supports mobile 2G Unicom 2G 3G. In other words, China Mobile Unicom can make phone calls. Unicom 3G Internet access will be faster. Here I have to complain again. After the back cover is buckled, the back plate and the flat plate are separated. I think it would be better to have a rubber band connection like this. Users like me who are careless may lose the back plate after opening it, and it is better to have a rubber link, so the back cover plate and the flat plate are inseparable.

After opening, I can't wait to insert my phone card In the Seven Rainbow G708 tablet, open the tablet to experience the feeling of using the tablet phone.

▲ First hand experience: after opening the tablet, after network settings, I entered the system, but after entering the system, I found that the system seems to use Lefrog OS system customized based on Android, the system's icon and call dialing interface, etc. I think it is basically based on Android native, because I am used to the deeply customized MI UI system, so the next MIUI system theme was set, It feels more comfortable to use. The system engineers of Qihonghong don't spray me here. I'm really used to the icons and interface styles of MIUI system, and I think they are very nice. Unauthorized modification of icons, etc. Please see Sorry. With simple use, the system is relatively smooth as a whole, the call experience is also good, the sound quality is clear, and I haven't found any problems when talking with friends for more than ten minutes. It's refreshing to use the tablet to make phone calls.

▲ Summary: The preliminary appearance and system call experience are good for me. The overall appearance is OK, and the system is also good and smooth to use. The experience of talking for more than ten minutes is also quite good. Considering the price of the Seven Rainbow G708, I really can't find any major problems. More detailed experience will be brought later.

The Seven Rainbow G708 is an eight core telephone tablet with a price of 399 yuan. It uses MTK6592 eight core processor, 1G running memory, 8G storage memory, 720P screen resolution, and full fit screen technology. Taken together, these hardware parameters make it hard to imagine that such a tablet only costs 399 yuan. As usual, even a 5-inch mobile phone with this configuration has to be 700 up. Not to mention the 7-inch tablet, in order to experience this 7-inch tablet, I think it is necessary to have a comprehensive experience of the screen and performance.

▲ Screen parameters: The screen of Seven Rainbow G708 adopts a 1280X720 resolution IPS wide view screen with full fitting process. The screen parameters and process are very good. Compared with ordinary screens, the IPS wide view screen is more expressive in terms of color permeability, more bright and transparent in color, and easier to see under high brightness or direct sunlight. Although the 720p resolution does not reach the retinal level ppi on the 7-inch tablet, it is acceptable for ordinary users.

▲ Solid color display: Seven Rainbow G708 Solid The performance is OK. The IPS panel with the full fitting process has a good color performance compared with the flat panel at the same price. Especially under the full black solid color, there is no light leakage, and there are no two bad points found under each solid color state. The quality control is still good.

▲ Gray scale display: Seven Rainbows G708 The grayscale is excessively natural and clearly layered, which is easy to distinguish. The grayscale display is good, which is mainly due to the fully fitted ips panel. Seven Rainbows G708 At most 5 points can be touched at the same time. Although it is less supported than the 10 point touch screen, in practice, on the seven inch tablet, it is difficult for you to use 10 points to control the touch screen at the same time. Five touch is OK.

▲ Appreciation of live screen shooting: The overall parameters of the Seven Rainbow G708 screen are absolutely good among the tablets at the same price. The 720p resolution, full fit screen, as can be seen from the following live picture samples, is also good in the actual picture experience. Although compared with the retina screen, there is still some difference in the fineness, but after all, this is only a 399 yuan tablet, and it is also an eight core tablet that can talk.

Seven Rainbows G708 The live screen effect is very good. For users who are not particularly picky about screen requirements, it is very good. Of course, the basis of these experiences is that this is a low-cost tablet with excellent cost performance. But you have to say that compared with the 2199 yuan iPad mini 2, the display effect of the iPad mini 2 is not as good as that of the iPad mini 2. On the contrary, it can be comparable with the iPad mini in terms of delicacy. The overall color restoration effect of Seven Rainbow G708 is good, the color is real, and the picture is relatively transparent.

Today, most Android tablets have excess performance. The performance experience can be summarized through the running score software. When it comes to running score software, Anthare is a performance testing software recognized by most people, and I personally like to refer to the performance based on Anthare's running score. It doesn't matter how high the performance is. It's enough. You can play mainstream games smoothly, watch ultra clear videos without cards, browse web pages smoothly, and experience various applications smoothly. I think this is the highest and best requirement for tablets.

▲ Anthare V5.6: Anthare believes that I don't need to introduce it too much, and many people also understand it. But for novice players who don't pay much attention to understanding this software, their scores can only be used to compare with other tablets, and their actual performance is almost unknown. Then, through my subjective experience, I will give you a rough classification. Today, there are scores from 1W to 5W on tablets, Here is an example of Anthare V5.6. For a tablet with a score of about 1W, there is little pressure to watch online videos, browse the web, and watch videos below 1080p, and its fluency is not so good. However, for large 3D games, the number of frames will be less, which can only be said that some large games can barely be run. The level from 2W to 3W can basically pass the mainstream 3D tablet mobile games. I personally think the gap is not so obvious if the score is more than 3W. Basic mainstream applications and large applications can run all over the world, and the gap is only the difference in the frame number of large games. Seven Rainbow G708 runs 2w7, which can cope with various mainstream application games. Let's put it this way, the actual score of Seven Rainbow G708 is higher than that of Red Rice Note 4g version, which is equivalent to that of Red Rice NOTE 3G enhanced version.

▲ Stability test: In Anthare v5.6, stability test of tablet or mobile phone is newly added. Through performance copying machine, data collection is conducted for tablet or mobile phone, and stability evaluation is conducted for its CPU and other processing performance. Whether it is very accurate is unknown. This stability is for your reference only. The stability test takes a long time, and you can have an intuitive experience of its stability curve and battery temperature after the test. As shown in the figure below, the smaller the curve fluctuation of the upper green curve, the more stable the performance is. The curve fluctuation in the figure is very good in terms of performance stability, and the fluctuation is very small. The battery temperature is also very stable, basically maintained at 28 degrees.

Use Master Lu to run HTML5, The Seven Rainbow G708 is definitely the mainstream performance in browser functions, and the performance of the 6592 eight core processor is really eye-catching.

▲ Summary: The seven rainbow G708 eight core version performs well on the screen effect. At a very low price, it gives the mainstream even more than the mainstream performance experience. Both the screen and the performance are completely enough for most people to use. How about actually playing games? More detailed use experience will be introduced later.

Although the price of the Seven Rainbow G708 is low, its configuration is definitely mainstream. The 6592 eight core processor is equivalent to the performance of the Xiaolong 600 processor and close to the performance of the Xiaolong 615 processor, The MTK6592 processor I have used Huawei's 3X before, and I also use this processor. I think this processor is optimized very well. It is not only mainstream in performance, but also hot. Compared with most CPUs, the standby power consumption also has considerable advantages. How about the Seven Rainbow G708 in mainstream entertainment experience? Let's try the performance experience with the game experience with the highest requirements first.

▲ Game experience: first try two large games The actual game performance of the seven rainbow G708 eight core version, Grand Theft Auto, I believe, is needless to say. Many people who like to play large games know that Grand Theft Auto is a game with relatively high performance requirements on the tablet, and can basically run this game smoothly. There are no problems with other games. In the actual experience, the Grand Theft Auto driver runs smoothly with sensitive touch, and the actual frame number is stable at more than 30 frames through visual inspection.

Wild and drag racing 8 is my favorite game. The Seven Rainbow G708 is also very smooth when playing Wild and drag racing 8. The frame number can be stabilized at more than 30 frames. So far, at the level of eight core 6592, there are basically no games that can't be played. Users who like to play games need to consider whether the downloaded large game data package conforms to the tablet GPU.

Of course, small games and some leisure games, The Seven Rainbow G708 is easier to cope with. It is sensitive to touch. The picture icon is larger than the mobile phone, and the picture is larger than the mobile phone. Compare the feeling on the phone as shown in the figure below.

▲ Online video experience: Seven Rainbows G708 online video is the most frequently used online video, such as Youku's ultra clear mode, I often watch the ultra clear mode of pptv and high-definition online videos such as Sohu Video and iQIYI. A year ago, I was worried about whether the tablet could watch the ultra clear video online, but now I don't have to worry about it. I have downloaded many online video software, none of which is not fluent in ultra clear. It is very smooth to watch with my 30M network drag.

The 7-inch screen of the Seven Rainbow G708 is much larger than the 5-inch mobile phone in your hand in terms of display area. Maybe many people don't know how much to call. The following picture is a comparison with the 5-inch mobile phone. Of course, the large screen means that the possibility of one hand operation is greatly reduced. Do you want to be big and comfortable, or small and refined?
▲ Web browsing: Seven Rainbows G708 Web browsing is the most basic use function. At 720p resolution, the font display is still very clear. As shown in the figure, the amount of information on a vertical page is also large, while the amount of information on a horizontal page is slightly small. When browsing the web page, it is recommended to view the web page vertically. Seven Rainbows G708 The tablet is really good for browsing the web and shopping.

▲ Reading experience.
▲ Summary: Seven Rainbow G708 eight core version, based on the mainstream 6592 performance experience, is well optimized. The performance is enough. The performance of games, videos, browsing and reading is very smooth. As a 399 tablet phone, the performance is very good. Outstanding cost performance.

The performance of the Seven Rainbow G708 is really good, with high performance and low price. Now in the tablet era with excess performance, I think the experience of system optimization is absolutely a very important aspect. The eight core phone version of the Seven Rainbow G708 is equipped with Lefrog OS system. Lefrog OS system and MIUI are basically the first Android systems developed and optimized for the second time in China, However, the popularity of MIUI is obviously higher today. Qihonghong can enable Lefrog OS system, which shows that Qihonghong is paying more attention to the system UI. Let me briefly describe the UI experience of the 7-Rainbow G708 8-core phone version.

▲ LeFrog OS: The design of LeFrog OS is almost the opposite of MIUI. MIUI is a system that integrates a lot of functions. Users hardly need to install much software when they get it. Common MIUI software is basically built-in. Lefrog OS, on the contrary, is to simplify and simplify almost all the software that can be simplified, including many things native to Android. To be honest, I don't like the simplified system. Some people really like the simplified system. They like to download the software and install all the software they like. I'm a lazy person, and I hope that once I get my mobile phone, Most of the software needed is already available, so I don't need to bother downloading and installing it. So I prefer MIUI system.

At the same time, Lefrog OS system icon and dial-up interface, SMS interface almost follow the original Android system interface, while I am still used to the MIUI icon and dial-up SMS interface.

The Seven Rainbow G708 eight core call version, as a call tablet, can be installed on almost all mobile phones' desktops and desktop themes. As shown in the figure, the WIN8 version of the desktop theme is more suitable for the elderly. I think the WIM8 version of the theme is more suitable for the elderly. The large dial interface is very obvious, and the tofu block's desktop icon is also easy to identify. Equipped with a win8 desktop, the seven rainbow G708 eight core phone version turns into a large screen phone for the elderly.

The screenshot of Lefrog OS system interface is very familiar to Lefrog old users, but I always prefer the system icon of MIUI. Regardless of setting or dial-up SMS interface, LeFrog OS almost always uses Android native, including the background cleaning provided by the system. LeFrog OS also uses Android native. To complain about LeFrog OS, there is no one click cleaning for this background program. You have to go to the additional one click cleaning software, which is really troublesome for lazy users like me.

The music player, file view, recording, calculator, etc. that comes with the Seven Rainbow G708 are almost simplified functions that cannot be further simplified. The music player does not support online song search, etc. The file manager is simple and the recording function is also extremely simple. Even the calculator is just a simple calculator, as if there is no advanced calculator. I can only say that the system is too simple...

In order to meet my personal usage habits, I set the MIUI system desktop theme, and dial-up and SMS interfaces look much more comfortable. and Seven Rainbow G708 already has a MIUI system that can be brushed. As a mobile tablet, its basic functions are the same as those of mobile phones, which means that mobile desktop themes can be used universally. So how many theme desktops are there? I believe you all understand.

▲ System summary: About I think the Seven Rainbow G708 is too simple. The factory system almost does not have any customized software. I need to install many common software when I get it. I am not used to it. I like the system with full functions when I get it. Of course, each has his own preference. The simple system makes the system less garbage and simple, Unused software will not occupy more space when installed on the tablet. Fortunately, for users like me, the Seven Rainbow G708 is a tablet phone, and the use of system functions can be solved by installing the phone theme or by self ROOT brushing. Whether you prefer a simple system or a system with many functions and complex functions depends on your personal preference.

The Seven Rainbow G708 is a cross-border product, which is both a tablet and a mobile phone. One phone has both in hand. The 399 yuan eight core 7-inch call tablet is really cost-effective. On the journey home, a mobile phone with a large screen and a convenient tablet can make our journey more enjoyable while waiting for boredom on the journey. The Seven Rainbow G708 has GSM and WCDMA networks. You can use your mobile phone card to access the Internet through 3G. It's really convenient to take this tablet with you on the journey. Do not bring a mobile phone, because it is a mobile phone, and do not bring a tablet, because it is a tablet.

On February 14, International Valentine's Day, I had to take a bus to accompany my girlfriend for the holiday because I lived separately from her. It would be faster to travel from Hefei to Bengbu by high-speed railway, but I arrived at the station ahead of schedule. It was estimated that the time was wrong. I arrived an hour earlier than driving. The people in the station were pretty good. As the New Year approached, many people had already returned home, and there were not too many people in the station. High speed rail G110 from Hefei to Beijing.

Boring waiting time. When I saw people around me, some were playing with their mobile phones and some were playing with their tablets. They were all waiting in boredom. They just took the Seven Rainbows G708 out to play games and surf the Internet. Previously, they had installed love elimination, wild car racing and other games in their tablets. It was best to pass the time without chatting.

It's better to play games on the screen. The size of 7 inches is just right, not too small, and easy to store.

With 3G network, it is very quick to open the web page. Look at the web page, see the news, and a lot of things about Valentine's Day. Fortunately, brother and sister have papers.

The Seven Rainbow G708 has a large screen and clear handwriting. I think it is more eye friendly to look at the web page than the small screen of my mobile phone.

Knife Tower Legend is a very popular game. I am also playing it. It has reached level 90. The newly added dream, the Tower of Thrones and so on are also quite interesting. Previously, I played it on a 5-inch mobile phone, but now I play it on a 7-inch mobile tablet. I suddenly feel that my career is open, the icon is large, and the painting surface is good.

The online fight against landlords is also one of the main games to kill time.

After getting on the high-speed railway, I pulled out the Seven Rainbows G708. There was nearly an hour left on the high-speed railway. This time, playing games and surfing the Internet would not be too boring. Chat on QQ, WeChat, etc. are all functions that we often play with mobile phones. Playing on the seven inch tablet of the Seven Rainbow G708 has another feeling.

The picture of the Seven Rainbow G708 is average. Compared with the ordinary 1000 yuan mobile phone, there is a big gap, but some is better than none. After all, the price is there. At a low price of 399, it includes mobile phone functions, eight cores, seven inch screen, camera, etc.

As a tablet phone, the 7-Rainbow G708 8-core 3G version runs smoothly. Although it only has 1G memory, it is also enough for ordinary users. After all, look at the hot mobile phones like Hongmi 1 and Lenovo K3, which also have 1G memory, Although 1GB of memory is not much, it is absolutely enough. Of course, if the Seven Rainbow G708 can be upgraded and added with 2GB of memory, even if it adds 100-200, it will definitely be the king of price performance.

The overall experience of using the Seven Rainbow G708 is that the screen is large, the performance is good, the price is low, the operation is smooth, the phone can be called, the 3G Internet can be accessed, and all mainstream applications can run smoothly. It is the most cost-effective tablet phone I have ever seen.
