Asus Zenfone 4 has many youthful color options similar to the Nokia X, competitors in the market today. According to Asus, this phone will have five color options including white, black, red, blue and yellow.
The case of Zenfone 4 is plastic with a rough surface that helps to grip and avoid fingerprints. The back of the Zenfone 4 is lightweight, giving the feel of holding hands when holding. On the front side, the angle of the machine is rounded look pretty soft. However, the design on the front of the Zenfone 4 has a thick bezel, especially at the bottom of the screen making it far longer than other 4 inch smartphones. Plus, the phone’s micro-USB charging port is upside down, not aesthetically pleasing and handy as it is at the bottom.
Details such as volume keys, power keys and connectors (audio jacks, micro-USB charging ports) are also well done, with neat lines.
The Asus Zenfone 4’s screen is about the same size and resolution as other smartphones and ranges: 4 inches, 800 x 480 pixels and a pixel density of 233 PPI. This is the average resolution that is sufficient to read newspaper online and use the applications on the phone.
When judged by the naked eye, the colors on Zenfone 4’s display are quite fresh, balanced in color, not as green as many other cheap machines and the screen brightness is also relatively high. On Zenfone 4, Asus also introduced a feature that allows users to manually adjust the color temperature, saturation and tint for the preference screen in the Splendid app.
The most notable weaknesses in this screen are poor viewing angles. When holding the camera horizontally, colors and contrasts almost disappear when viewed from left to right. This problem will greatly affect the viewing experience, such as playing Need for Speed, Asphalt 7/8, or Riptide. The screen protector is also slightly glossy, so it is hard to see when used in the sun. In addition to the cheap, the Zenfone 4’s screen also has no light sensor to automatically adjust the brightness, so users have to manually increase the brightness to suit different environments.
When measured on specialized equipment and software, Zenfone 4 performs better than the same price range in many basic criteria such as blackness, contrast, color temperature and color accuracy. However, also note that the screen on cheap phones often display non-standard color as on the mid-range and high-end.
Considering the specs, the camera is also the detail that Zenfone 4 has superiority over the same price range. This phone has a 5MP rear camera and a 0.3MP (VGA) front camera. In particular, the rear camera can shoot full-HD resolutions up to 30 frames per second (fps).
The camera application supports a variety of imaging features including HDR, panorama, GIF animation, self portrait, night capture, font removal, motion picture deletion, skin beauty and night shot mode.

We have experienced the Asus Zenfone 4 camera in detail, including quality comparisons with the Samsung Galaxy Pro laptops, NokiaX and Lumia 525. In general, the camera of this phone has the advantage. With the Nokia Lumia 525 and Samsung Galaxy X Lite and Nokia X, the two are priced at $100 equal Asus Zenfone 4 in the market now.
Software and performance
Zenfone 4 comes pre-installed with Android 4.3 (the manufacturer said it will soon be updated to Android 4.4 KitKat) along with Asus’s Zen UI customizable interface. Zen UI interface on this phone looks quite simple with icons designed squarely.
Looking at the interface of Zenfone 4 can be seen Asus has incorporated a little flat design style of iOS to his Zen UI. Asus also integrates several small applications in addition to familiar Google applications such as file manager, notes, audio editing software (AudioWizard) and screen adjustments (color temperature, saturation and sharpness). color).
It can be said that Asus has equiped the new Zenfone 4 Android version with a simple Zen UI user interface. However, software is not a factor to be concerned about on this phone but new performance is the point to be noticed.
Smartphones at a competitive price with the current Zenfone 4 such as the Nokia X and Samsung Galaxy Trend Lite usually have only 1GHz single-core or dual-core processor and 512MB of general-purpose RAM. Meanwhile, the Zenfone 4 is favored by manufacturers for dual-core 1.2GHz processor from Intel and RAM up to 1GB. This has made the machine smoother than the competition and play heavy 3D games that the same price range does not run or jerky.
When it comes to practical experience, Zenfone 4 is fast-paced with the ability to move between home screens, screens in the application tray, and for using the basic applications available on the phone such as calling, texting trust or open contacts list. The speed of web surfing is also fast, taking only about 4-5 seconds to open a website on BiaReview’s good Wi-Fi network and smooth scrolling.
This cheap phone also handles popular games like Temple Run 2. For heavy games like Need for Speed Most Wanted, Zenfone 4 does not play smoothly but does not jerk, slow to the annoying level. In general, the machine performs very well in the price range. Only one thing to keep in mind is the limited screen viewing angle, which greatly influences the experience of tilting the screen like Need for Speed. Also in battery testing, Zenfone 4 also consumes battery power fast for gaming activity.
When measured on the overall performance measurement software Antutu and Quadrant, Zenfone 4 scored much higher than the machines priced at $150-200 and reached the point of evaluation of these two software is good enough to play the game mobile has beautiful graphics.
Zenfone 4 has a memory of up to 8GB (with 4.6GB of free space for users), is also a big advantage over the same price range is only 4GB with an external memory card expansion to 64GB. However, the speakerphone of the machine has a slightly small volume and the operating image of the speakerphone detector of this phone does not have loudspeaker box. Maybe this is the reason why the loudspeaker of the machine has a small volume, because if the loud volume without the loudspeaker box will make the sound is hissing, poor quality.

With a relatively small 1,200mAh battery, perhaps the battery life is the most concerned about the Asus Zenfone 4.
In the BiaReview standard test for movie viewing, calling and gaming in a simulated environment, Zenfone 4 performs relatively well in movie watching (4 hours 15 minutes) and calls (8 hours 35 minutes). But battery life is fast in gaming tests (1 hour 45 minutes).
In real life, the battery life is fast when playing games and watching videos on YouTube, while surfing the web is slower. In particular, Zenfone 4 lost 18% of its battery power after 30 minutes of Temple Run 2, 13% of its battery after 30 minutes of Wi-Fi and 20% of its battery life after 30 minutes of YouTube video. With such results, Zenfone 4 users will need to consider the use of a second battery pack when purchasing a Zenfone 4.
In the overnight standby mode, Zenfone 4 takes about 4% of its battery life after 8 hours while the laptop is still on Wi-Fi. This is the level of acceptable battery life for low-cost smartphones, though still higher than mid-range machines such as the Sony Xperia M2 that lost just 2% after similar waiting times.
Zenfone 4 is superior to smartphones at the price of $100, such as Samsung Galaxy Trend Lite and Nokia X for agility, large capacity memory (8GB), camera with many features and more detailed photos. The handset has easy-to-hold design, multiple color options, and comes with a brand new version of Android 4.3, while promised to be updated to Android 4.4 KitKat soon.
The most noticeable issue in this phone is its small capacity battery that demonstrates fast battery life with gaming and YouTube video playback. Even though the manufacturer offers one more battery for backup but due to no charging dock, the use of this extra battery pack is not convenient. In addition, the screen of the Zenfone 4 has a poor viewing angle, greatly affecting the need to play games that need to inclined the screen control.
