appearance
Coolpad Grand View 4 adopts a rectangular round corner design, and the left and right borders are very narrow!
At the top center of the screen is the earpiece, on the left is a front 2 megapixel camera, and on the right is a sensor.
At the bottom is a physical Home key, and there are two capacitive touch keys on the left and right.
There is a special texture on the back, which is simple and will not appear too monotonous.
The camera is in the center, and two LED fill lights are beside it.
The camera protrudes slightly, but the camera glass is slightly lower than the outer circle, which can protect the camera from scratches.
Grand View 4 has a dual speaker design. There are speakers at the bottom and top. In order to enhance communication, the middle metal layer will have several sections, which is normal.
Grand View 4 has a one button mute design. The one on the power button is the mute key, and pressing it when necessary is the mute key.
The volume key is also made of metal, which feels good.
After opening the back cover, you can see that the dual card dual standby design of Daguan 4 has been completed. This one in Xiaobian's hand is a customized version of Telecom.
Grand View 4 uses a 5.9-inch 1080P screen, and the viewing effect is very good.

performance
Anthare didn't say much about it. The score is 31632, which belongs to a relatively normal level. The GPU performance seems to be weak. I don't know whether it is a problem that the engineering machine has not been well optimized.
GFXBench is a professional software for testing the GPU performance of mobile phones. The score is not ideal, and the GPU may not be optimized (reference model: Xiaomi 3 TD version, and the frame number of 2.5 Offscreen project is 57).
Vellamo is a software launched by Qualcomm to test the HTML performance of web pages. HTML 5 scored 2108.
3D Mark, in this test, the GPU performance is also slightly lower than expected, and the GPU performance should be better played when the official version arrives.
SunSpider， Using Chrome Bate, the final result is 584 ms (the lower the value, the faster), which is good.
From the above results, the GPU optimization of Daguan 4 engineering version is not very good, but it is believed that with the powerful strength of Coolpad, it is very easy for the official version to solve this problem.
game
NBA2K14, a large-scale basketball competitive game recently released by Androidy, has very high hardware requirements.
In the running process, the frame number performance is good, the average is about 25 frames, the picture details are good, the character details and the floor reflection are good, and the high special effect operation.
In Modern War 4, the picture effect is not high special effect, and the details are vague.
The average number of frames is fairly good, but some big bang and the like will get stuck slightly, which may be due to poor optimization.
Pacific Rim is a fighting game adapted from the movie, and its playing method is similar to that of Endless Sword.
The picture of the game is very good. The game has a variety of mecha and different monsters, and the frames are basically more than 50.
In Real Racing 3, the frame number is not very stable. The average frame number is about 30 frames.
From the above game experience, the effect is not very good, and Tegra 4 has not yet fully played its full power, especially the GPU frequency reduction. It may be that the physique obtained by Xiaobian is relatively poor, because the two machines sent in, the other one will run a little better than the Xiaobian one. I believe that when the official version comes, Coolpad can definitely solve this problem.
UI&System
CoolLife UI 5.0 is used in Coolpad Grand View 4, which is a set of UI designed by Coolpad itself. It basically maintains the original Android, and adds its own redesigned icons and plug-ins. In addition, there is a news integration page, where you can browse instant news by sliding up and down (you need to connect to the network).
The style of icons and plug-ins is basically consistent, and the icons for installing third-party applications will also be covered with a box.
The built-in cool show allows you to change different themes.
Grand View 4 uses Android 4.2.2 system, and also retains the design of double finger pull-down to call all shortcuts.
By default, Grand View 4 cannot click the Home key to wake up the screen, but it can be added to the auxiliary functions. In addition, there are some intelligent control settings.
In the dialing interface, click the red circle in the figure above to use the one hand dialing keyboard.
Speed dial can be set freely in the phone settings, and there is a quick search tool in the address book to help you find contacts quickly, which is really good.
The design of the dual card management is good, and the built-in vibration design for making and ending calls is also considerate.
The system has a folder containing various gadgets and shortcut settings. The compass can also measure the air pressure and altitude at that time, which is very considerate and practical.
The unique security mode of Coolpad can also ensure that your data will not be lost or stolen. In addition, there are some health detection applications, but they can only be realized with the special accessories of Coolpad. Because the small editor has not got those accessories, it can't be tested.
The video preview interface will capture a video GIF and play it on the preview interface, so the preview interface is dynamic, just like a magic album.
2G RAM also ensures smooth operation of the phone.
Although the CoolLife UI 5.0 of Grand View 4 is mostly based on the original, it also adds its own design elements, redesigned icons and some intelligent control and user-friendly convenient functions. The system design is relatively mature. 2G RAM ensures smooth operation of the whole machine, but the built-in storage space of only 16G is not enough. Fortunately, it can be remedied by inserting a TF card.
Video playback
The video is played using MX play hard decoding:
My sister is not so cute, MP4 format, 720P, playing and dragging smoothly.
The Song of Ice and Fire, RMVB format, 720P, can be played and dragged smoothly.
The Big Bang Theory, in MKV format, 720P, plays and drags smoothly.
Iron Man, MOV format, 1080P, playing and dragging smoothly.
The trailer of "Assassin's Creed", MP4 format, 1080P, plays and drags smoothly.
The Big Bang Theory in MKV format, 1080P, plays smoothly, and does not get stuck when dragging.
Battlefield 3, MP4 format, 1080P, large bit rate video of 60 frames/second, plays and drags smoothly, and basically keeps 60 frames playing.
From the above experience, the playback ability of Grand View 4 is quite good. 5.9 inch, 1080P high-definition large screen brings a very good visual experience!
photograph
Grand View 4 is equipped with Sony's latest 13 million pixel, F2.0 large aperture camera. The daytime imaging is good.
The macro performance is also good, very soft outside the focus, and clear details inside the focus.
For night scene imaging, in order to ensure a brighter picture, the system uses a high ISO of 1600 by default. In fact, such a high ISO will hurt the picture.
It is better to adjust the ISO according to the environment. Even if the picture is darker, it is better than full of noise.
Due to the limited space, the shooting evaluation of Coolpad Grand View 4 will be updated in the future. Please pay attention.
fever
After playing the game for half an hour, the hottest temperature at the top left of the horizontal screen is 42 ℃.
The hottest part on the back is also at the same position, the hottest part is 45 ℃. Of course, because the frame is metal, the thermal conductivity is strong, so pay attention when using it.
Endurance
When about 50% of the power was left, the brightness of NBA2K14 was set to 100% and played for half an hour. After the game, 15% of the power was left. At last, the microblog was used normally for 20 minutes. After 50 minutes, 6% of the power was left. Although the Grand View 4 uses a 3000 mA battery, after all, the screen is large, which will add a lot of burden to the endurance. In addition, the Tegra 4 is not a power saving product. Although it has a power saving core, it still consumes a lot of power when playing games with full power. Fortunately, the battery can be replaced. If you have high requirements for endurance, you'd better bring an extra battery.
summary
This time, Coolpad Grand View 4 followed the trend and used Tegra 4, a powerful processor, which improved the overall performance of the mobile phone by more than one grade! The 5.9-inch FHD screen and the ultra narrow frame design show the cool and solid industrial design, and the metal inner frame further improves the solid degree of the whole machine. The appearance design is simple and elegant, and the dual speaker design can have a very good listening experience when watching videos!
In the process of testing the game, the GPU optimization of the engineering machine was not enough, so the performance in this aspect was not strong enough. But when the final version was released, I believed that the powerful power of Coolpad would perfectly eliminate this problem. As for the audio and video experience, Grand View 4 has always had an excellent performance. In terms of shooting ability, Coolpad Grand View 4 uses the 13 million pixel camera of Sony Stack, and its shooting ability has been further improved by excellent components and Coolpad's excellent camera optimization ability.
In terms of the system, although based on the original, Coolpad has added its own design elements, as well as some intimate small functions. The excellent design of dual card dual standby has experienced Coolpad's powerful mobile phone design and production capabilities. Due to the use of Tegra 4, this processor is already very hot, so the Grand View 4 is a little hot. It's good to pay attention to its normal use. In addition, the battery life is also due to Tegra 4, an electric tiger, which consumes a lot of power when playing games or dealing with multitasking and large software. For those who have high requirements for battery life, it is better to reserve an extra battery.
In general, Coolpad Grand View 4 has changed the impression of Coolpad in the past. Its powerful processor, excellent industrial design, intimate functions and increasingly demanding dual card dual standby functions are all exciting! If you want to buy a mobile phone with operator subsidies, you need a powerful mobile phone with large screen, dual card and dual standby. Kupai Grand View 4 is a good choice.
