Although the battery life is not as good as expected, Oppo Yoyo R2001 is still a noticeable choice among the same segmented products by its good performance, good looks, camera features, beautiful ColorOS interface, easy to use.
The Yoyo R2001 is a mid-range, mid-range smartphone that Oppo recently launched, targeting young, dynamic users. The handset has a slim, eye-catching bezel design and shiny metallic bezel along the sides of the device. In addition to the white-sanded version that contrasts with the glossy black screen surface, the Yoyo R2001 also has the option of using a glittering back cover on blackish-black paint that looks quite attractive.
The Yoyo R2001 features a 4.7″ IPS panel technology that promises quality assurance at narrow viewing angles. The handset is also equipped with two SIM slots (a micro-SIM slot) supporting both GSM and 3G (WCDMA). The internal power of the machine is a combination of quite powerful hardware components such as 1.3GHz Mediatek quad-core processor, integrated Mali-400MP graphics core. But to reduce some of the cost to end users, RAM capacity on the Yoyo R2001 only Oppo limited to 1GB. The memory capacity of the machine is still only 4GB, but in return, users still have the option to expand the storage space with microSD memory card (maximum capacity of 32GB).
Of course, the Yoyo R2001 also supports full range of sensors such as light sensor, proximity sensor, digital compass, gyroscope … To serve as The Yoyo R2001 is also equipped with a 5-megapixel main camera with a built-in LED flash. The front-facing camera is also upgraded to 2-megapixel, which promises to better serve the needs of video conferencing through the Internet. In addition, the ColorOS operating system on the Yoyo R2001 has also been upgraded to version 1.2 supporting more touchless gestures and lock screen gestures than the older versions.
The special feature of the Yoyo R2001 is the wireless connection near HotKnot with data transfer speeds up to 5MB / sec. This smart wireless connectivity solution, like NFC, just touches the screen of two compatible devices for high-speed connectivity and data transfer. In addition to this connection, the Yoyo R2001 also supports Bluetooth, GPS and OTG connectivity for use with PCs and peripherals.
Design, screens and performance
With dimensions of 138.5 x 69.5 x 9.2 mm, the Yoyo R2001 looks quite “long” but very hand-friendly compared to looks. Despite using most of the plastic material, the Yoyo R2001 is still very solid. The white back cover version available at Test Lab has good adhesion – but not too sensitive to dust during use. The physical button cluster design (power button, volume control) on the Yoyo R2001 is well laid out and easy to familiarize. The soft keys of the Android platform on the Yoyo R2001 blend seamlessly with the black tones of the screen bezel, which looks nice and does not bother you in a dimly lit environment. LED backlight is quite sensitive. The actual exposure shows that the Yoyo R2001 has a good exterior design, suitable for young users. However, the downside to the seamless design of the mainstream is that users do not have the option of replacing the hot-swappable SIM or memory card.
While supporting only the qHD resolution, but with a pixel density of 240dpi, the Yoyo R2001 can easily pass the Test Labs visibility test. Trials on the granularity of the 4.7 “screen all gave good results as expected. Even small letters in the name of the application on the home screen still look “sharp”, without the aliasing. The ability to reproduce the color of the screen is also pretty decent because color uniformity, black saturation also looks very attractive. However, according to Test Lab, the IPS panel still does not give the most power to the viewing angle due to the large gap between the screen panel and the protection glass, plus the glossy surface when setting low brightness. Fortunately setting a screen brightness above 30% can partially overcome this obstacle.
Compared to some smartphones that have been tested, the Yoyo R2001’s automatic screen brightness control function works smoother. But throughout the testing process, the speed of automatic brightness change is still rather slow compared to changes in the environment. Particularly for touch control operation, Test Lab almost without any obstacles. The touch screen is highly responsive and responsive even when using gloves – even though the screen surface remains sensitive to fingerprints.
With the strength of the MT6582 quad-core processors, designed by Mediatek based on ARM v.7 architecture and released in mid-2013, the Yoyo R2001 can easily pass office tests, multi-processor performance Fun, as well as entertainment with HD movies. Throughout the testing process with specialized benchmarking tools, Test Lab found that the final score that Yoyo R2001 achieved was very positive. For example, Epic Citadel’s graphical performance test shows that the camera has a high frame rate even when using the “High Quality” setting. The actual usage shows that the machine has screen transfer speed, navigation between control menus and switching between applications smooth. However, due to the limitation of main memory capacity, the startup speed of heavy applications is sometimes slow, especially when there are many applications running in the background. Particularly for games, the Yoyo R2001 is also capable of satisfying high-speed 2D games like Sonic Dash, Temple Run – to 3D action games like Dead Trigger 2, FiFa 14, Iron Man 3, Real Racing 3. However, in many zoombie scenes; Yoyo R2001 sometimes appears as a slight stoppage.
Compared to the previous ColorOS versions, the upgrade adds a slew of Screen-off Gestures alongside many of the other major enhancements that bring a lot of convenience to the user. For example, the machine allows some gesture in front of the secondary camera to switch screen pages on some applications, take screenshots by 3-finger scan, auto answer the call when the phone is placed near the ear, open Screen by double tap. Users also have many options to customize the interface ColorOS in his own style because the machine supports a lot of pre-installed themes as well as online theme. The Yoyo R2001 also has a large numeric keypad, which is easy to use with one hand, but does not take up too much of the annoying screen area for quick viewing of conversation lists. Throughout the testing process, the call quality was generally stable, sound was clear. The built-in microphone has a wide recording range and does not cause echoes at the test strings. Loudspeakers are generally “fit” for hands-free conversation rather than entertainment – as loudspeakers are occasionally subjected to minor shaking.
Particularly for the camera, in good light conditions, the Yoyo R2001 has fast autofocusing speed – but the ability to capture fast motion is somewhat limited. In terms of imaging performance, image reproducibility over some of the same products and segments tested, the Yoyo R2001 offers the best color saturation – albeit in some cases The camera’s automatic metering capability is a bit limited. The lack of brightness, autofocus capabilities, color reproducibility, and camera detail are still limited. The flash light comes on once activated but also fixes some of the illumination phenomenon, but the range is still somewhat limited. Best users should use the Fill Flash feature to limit red-eye at portraits in low light.
The 1,900mAh battery on the Yoyo R2001 generally suffers from a long day spent using Wi-Fi to connect with friends and moderate listening / call / messaging frequencies. Particularly in the battery performance test by showing HD movies, activating most of the connections, constantly updating background apps, combining the use of most custom gestures, gestures in the application. Lock screen and set the maximum screen brightness – the battery attached to the machine can “hold” about 4 hours 29 minutes.
In a nutshell, Oppo Yoyo has a nice, easy to use interface and lots of touch-screen controls. The camera incorporates many imaging options and is quite good quality in good lighting conditions. However, the limit on the amount of memory that will integrate users to consider when installing more heavy graphics games.
