ceqv1m1N8X8tEThe 4.5-inch screen OPPO Ulike2 belonged to the mainstream screen at the beginning of this year while it is obsolete at the moment when the large-screen becomes dominant. Thus, some optimization must be made in OPPO U2S. OPPO U2S features a 5.5-inch screen with the 1280×720 pixel display,which has the excellent display effect. The visible angle is 180 degree.

Meanwhile, it is also with the Corning 2G glass screen.

At the very start of the this year, OPPO Ulike 2 that focuses on the shooting function was released. Its 500W pixel display front-facing camera is of course the highlight among the smart phones. Moreover, the smile shooing and the extreme beautifying function are also quite popular even up to today.
Just a few days ago, the upgraded version of OPPO Ulike 2-OPPO U2S was issued, in which the screen size and functions are developed a lot. Then we will come to review the performance.

Since it is the smart phone focusing on the shooting ability, the design of its appearance of course takes the female aesthetic standard into account. The four corners are with the arc design and the frontage is surrounded by the silver edging decoration stripe. The height of the screen is slightly higher than the edging, which is quite impressive. The size of OPPO U2S is of 152×75.8×9.4mm and its weight is of 182g.
Above the screen is there a receiver of the shape of pinhole and on the left side of the receiver are the sensors. A charging signal is on the left side of the sensors while on the right side of the receivers is a 500W pixel display front-facing camera. When the screen is touched, the virtual keys will be lighted.

Quadrant Advanced Edition

Quadrant is the senior-level mobile equipment testing tools developed by Aurora Softworks, which includes storage test, four I/O test, 2D graphic processing test, three 3D graphic processing test to have a comprehensive feedback of tested equipment. The equipment without GPU unit cannot process this program. In theory, higher score equals the better comprehensive property.
Quadrant includes three versions of Standard、Advanced、Professional. Besides final tested result, the Advanced version also provides offline browsing. There is no difference between Professional and Advanced version in function, only the former caters to commercial consumers(such as agent, cell phone manufacturers),and the price of software is higher. Our test selects Quadrant Advanced Edition.

the test of CPU property
AndEbench includes two performances of AndEMark Native and AndEMark Java.

AndEBench is the software issued in 2012, which provides the way to evaluate Android’s platform property and can test CPU and Dalvik( Dalvik is the virtual machine in Android system, which is to process the application programs, so it’s also the important property.) and compare the difference between Java. The software can also testify the function of multithreaded performance and the final performance is for the pre-installed application’s execution efficiency and the installed application from the third party’s execution efficiency.

It has become the most popular benchmark to test high-quality computer system’s floating point function. Compared with tablets, Linpack of Android cellphone is relatively simplified. The updating version includes the test of single-thread and multiple-thread. As its name implies, the higher score means better calculation ability of processor. The dual-core or multiple-core processors’ advantages shall be shown in the part of multiple-thread test and the result is shown via Flops.

Performance test2/ conclusion
GPU test——

3D Mark is the software to test the video card’s property put forward by Futuremark. With the upgrading of those software, 3D Mark has become the software to measure its comprehensive function. In February,2013, after the release of the 3D Mark11, the product of the new generation is launched with the name 3DMark. Besides Windows platform, other three versions such as Android, iOS and Windows RT are added. Three situations are loaded for 3DMark, in which FireStrike which is specially designed for the high-end product based on DirectX11, Cloudgate based on the mainstream hardware DirectX10 and IceStrom designed for the entry-level Direct X9. However, only IceStorm is reserved in versions of Android and iOS.

Though the complexity of the tested animation varies in IceStorm and IceStorm Extreme, the content is the same. Three tests are included- Graphics test 1, Graphics test 2 and Physics test. The first two tests are to check the GPU property, in which graphic test 1 focused more on the vertex shader in the condition of declining pixel load; graphic test 2 is prone to pixel rendering and post-processing. As to the third test, the CPU’s property is mainly examined. The animation background adopts static pictures, which is in order to decline the effect of GPU and test the CPU’s physical property.

As to the terminal, the system version of the tested Android equipment needs to be better than Android 3.1, have over 1GB RAM storage and over 300MB ROM storage as well as also contain OpenGL ES 2.0. iOS’ version shall be better than iOS 5.0. with regards to the Apple products, it should be the products which come later than iPhone4, iPad2, iPod5 and the storage shall be more than 300MB
Basemark ES 2.0 Taiji

Basemark ES 2.0 Taiji is the software to test graphic image, in which the situation that a girl is playing shadowboxing is preinstalled to test the equipment’s three-dimension graphic function, which can examine the speed of the equipment in processing games and pictures.

Sunspider0.9.1 is the software to test the web browser by virtue of checking out the display speed of kinds of data and pictures. The tested programs are rather multifarious, including 3d、access、bitops、math、string and so on. After the test, the gross score will be obtained. The lower the number is, which means the needed time to display the kinds of information is less, the better the property of the browser is.

Vellamo is the benchmark testing application developed by Qualcomn(it’s like Neocore), which can test the property of your cellphone and its stability, including Java, network and interface. Likewise, it also includes several testing programs, but only the gross performance is concluded. The higher score means better level of optimization and nicer web browsing.
As the benchmark tool of cellphone webpage, Vellamo includes two main models. HTML5 model can be used to evaluate the property of mobile webpage browser while Metal model is applied in measuring CPU’s subordinate system’s property of mobile processor. The test suite can be applied by clicking, which is convenient and fast. Kinds of categories including repeated playing, 3D graphic image, video, RAM/ROM can be evaluated.

HTML5 test——

Fishbowl(25 fish are set)

The name “fishbowl” indicates that the property of HTML5 is tested by the image of a fishbowl which is full of fish. The number of the fish can be set. During the test the fish in the bowl are swimming. Provided that the number of fish is the same, the quicker they swim, the better property the HTML5 is. On the left side of the interface the score is also provided, likewise, higher score means better function.

As the next main revised edition, HTML5 is still in development, whose main advantage is reinforcing the performance of webpage, and providing better optimization of searching engine. The webpage APP is operated more quickly and is linked to the network more quickly and it will perform better in downloading pictures and more exquisite webpage animation effect.
Conclusion: At the moment, consumers are paying more attention to the size of the screen. OPPO U2S is with the 5.5-inch large screen is quite outstanding among the smart phones. Moreover, its 500W pixel display front-facing camera is also the highlight.
During the times when the function of taking pictures is so important, OPPO U2S is applied the large screen, quad-core professor, high pixel display, which is indefinitely outstanding and sure to make a hit.

1 It is of the 5.5-inch large screen.
2 It is of the 500W pixel display front-facing camera.
3 It is of the quad-core processor.
The noise can be seen in some sample pictures taken in the evening.
