Asus zenfone 4 review in Spanish (full analysis)

A few weeks after the Christmas campaign ASUS has launched one of its star mid-range terminals. We are talking specifically about Zenfone 4, with which the company has put all the meat on the grill in regards to the cameras it incorporates and the quality of these. At first, things look good. Take a look at our review.

We thank Asus for trusting the product for its analysis:

Unboxing

Already in the serigraphy of the box it is evident with the phrase We love photo which is the section that they want to highlight of the terminal. Inside we find quite well organized:

Design

The Zenfone 4 has a unibody design with measurements of 75.2mm x 155.2mm x 7.5mm and a weight of 165 grams that is hardly noticeable in the hand. The terminal's greatest success is its rounded lines on the aluminum chassis and the glass construction of the rear with a concentric texture.

If beauty is its strong point, its ergonomics is a somewhat weaker point. Despite the fact that the use with one hand is very good and holds perfectly, it is not surprising that it can sometimes slip from the hand in an oversight as the chassis does not have a more rugged super. You can not have everything. The same happens when resting the device on some slightly inclined surface, the perfect uniformity of the back makes the Zenfone 4 slide little by little. It is not something that only happens to this terminal, but you have to be careful with it. Luckily, both these bugs can be solved by using the built-in gel case in the box. A cover that will also protect you from bumps and falls. Such decisions are to applaud and make everyone happy.

The front part has Gorilla Glass protection and a 2.5D contour on the edges. This does not mean that there are some small side frames and other quite wider ones above where the selfie camera, the call loudspeaker and the proximity sensor are located; and below where we find the fingerprint sensor and touch buttons to move around the system.

On the back, also with Gorilla Glass, the two cameras stand out at the top along with the flash and the ASUS logo is centered and screen-printed in silver.

On the side edges we find the usual arrangement. Volume and on / off buttons on right side. The nanoSIM and microSD slot on the left side. The only surprise is finding the top edge clean except for the noise canceling microphone and on the bottom the 3.5mm jack plug, the microUSB type C port, the call microphone and the multimedia speaker.

As seen, ASUS has chosen to include more conservative design features such as the touch button panel and frames, and more current ones such as the fingerprint sensor and the 2.5D front.

screen

We find a 5.5-inch screen. Although, it may seem larger at first due to the size of the terminal. Its FullHD resolution gives us a density of 401 pixels per inch. All this, together with IPS technology, provides us with a very good image quality. Both in color vividness and sharpness and viewing angle, although the latter could be even better.

At any time from the settings section it is possible to change the hue, saturation or temperature of the colors. It is a detail that always comes in handy and notes the good work at the software level.

In its outdoor use we have not had any problem to be able to see the screen at any time. It was something to expect knowing that it has a maximum brightness of 600 nits.

Sound

Playing multimedia content through the speaker leaves a good taste in your mouth by offering good sound power. Speaking of its quality, it is true that it tends to sound a little more distorted than the score. Above all, with maximum volume. It is an aspect that has left me a little cold considering that the terminal uses both the standard speaker and the calls.

Luckily my thing is music with headphones, and this section, despite not compensating the other, does offer more than notable quality with DTS certification . The included headphones also offer a good equalization.

OS

The Zenfone 4 comes by default with the update to Android Nougat 7.1.1 and with the promise of the company to incorporate Oreo in the future. On the other hand, we find the ASUS ZenUI 4.0 layer with a more minimalist design than what we are used to and with fewer unwanted applications, which does not mean that none come.

The desktop, as each one is more common, has few differences with pure Android and bets by default for both the folders and the application drawer. To everyone's liking. The only thing that can squeak a little more is the inclusion, as I mentioned in the previous paragraph, of the apps put in shoes such as customizing the theme, optimizing the system or Instagram. Although users prefer to install our own apps and companies add less and less, there is still a short way to reach the approval.

There are settings such as screen color mode, simple mode for the elderly and child mode for safe use for minors, which are always well received and give versatility to the system.

Other interesting adjustments are the cloning of apps to use two different sessions of the same, the bookmarks when browsing the Internet, the use of gestures of movements and tactiles, the use with one hand or the possibility of recording and optimizing games in video games for immediately stream on Youtube or Twich.

Lastly, the OptiFlex adjustment allows applications to be optimized automatically based on how we use them.

The operating system responds quite well both in fluidity and in use, and we have not had any type of bug or problem during the time that we have tested it. Today, that is saying a lot and they demonstrate the commitment put by the company in this section.

performance

The Zenfone 4 houses a processor according to its range, specifically a Snapdragon 630 with Kryo 280 architecture and with eight cores. Four of them go at 1.8 GHz and the others at 2.2 GHz along with an Adreno 508 GPU. To this is added the 4GB of RAM.

All in all, we came across really good specs on paper before. This hardware helps the system run smoothly at all times. By adding a bit more reed and working to the processor with demanding games, we have been able to see that it performs perfectly. It has even passed the test while playing while making use of video capture during the game that incorporates Zenfone itself without noticing any drop in frames.

The AnTuTu and GeedBench benchmarks have given a performance score of 68397 and 857 respectively.

We must also remember that the terminal comes with 64Gb of internal storage with the possibility of expanding it with microSD.

Finally, the fingerprint sensor does not stand out from other competitors. It works well and detection is fast, but sometimes it does not fully recognize the finger in slightly more tilted positions.

Camera

And we find the section so highlighted by the brand. This time ASUS mounts on its rear cameras, on the one hand, a 12.2-megapixel Sony IMX362 Exmor RS sensor with a 1.8 focal aperture and an 83-degree lens on the main and an 8-megapixel sensor, 2.0 focal length and 120 degree wide angle on the secondary camera. All this combined with optical image stabilization.

Jumping to the core, it should be noted without a doubt that the quality of the photos in well-lit environments is great. The captures have a very good definition and vivid and natural colors without image washing or overexposure. The contrast on the other hand is more than correct. The same goes for autofocus which has typically worked efficiently and quickly.

In night scenes or less illuminated the main camera behaves in a more than decent way. The captures made obviously sin of a greater noise, but they do not reflect badly the colors and the contrast.

The use of the dual camera is intended to achieve the Bokeh effect . It doesn't end up being very spectacular. The software is more to blame for this, needing some improvement still.

Another option that may be interesting is to switch between the main camera with a smaller angle and the secondary camera with a wide angle. The latter offers us greater image capture, but at the cost of sacrificing some quality.

The camera software also has a PRO mode . Through its use, manually modify the different parameters and even the possibility of leveling the image before shooting.

It is possible to record video in various resolutions and with optical and electronic stabilization. The modes are 1080p 30fps, 1080p 60fps, and 4k 30fps.

At the front we find an 8 megapixel camera and with the possibility of recording video up to 1080p. For selfies we find a camera that complies correctly. As an extra configuration add a beauty mode.

Battery

It seems that it is fashionable to use a 3, 300 mAh battery although in the end the important thing is how it is managed. Quality before quantity. In this case you can only have good words and affirm that there is quality. Making normal daily use of the terminal (surfing the internet, chatting and photographing) , the end of the day was reached with a third of the battery. And without making any load it was possible to arrive at the following noon.

In case you have to charge the device in a hurry, BoostMaster technology allows you to charge a good percentage of the battery in 5 minutes. With half an hour the charge is up to half the capacity.

Connectivity

In this section, the Zenfone 4 stands out by including Bluetooth 5.0, support for LTE Cat. 12 and 13 networks, Wi- Fi 802.11ac Dualband with MIMO, NFC and GPS using GLONASS.
