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.
(the frontage of OPPO U2S)
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.
(it is 9.4mm thick.)
In the aspect of the key arrangement, OPPO U2S is almost alike to others and the keys, interface are designed on the surroundings.
the Baby Skin spraying technology is outstanding.
The back core of OPPO U2S adopts the Baby Skin spraying technology, which seems to be with the matte texture and good to prevent the fingerprints. On the low side of the back core is the position of the loudspeaker while the 800W pixel display main camera with LED flashlight is on the upper side.
(the 3000mAh battery)
it is not quite easy to open the back core of the OPPO U2S and the workmanship is quite professional. When the back core is opened, a 3000mAh battery comes into our sight, which is enough to cope with the daily applications. Above the battery compartment are the two SIM card slots and support GSM/WCDMA model.
The various OPPO applications
OPPO U2S adopts the Android 4.2.1 OS and it is further developed by OPPO. The wallpaper, the special effect in switching the interfaces, the themes and so on can be reset by clicking on the menu key on the desktop.

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.
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
