[Preface]

In recent years, as major mobile phone companies expand their territory into the low-end mobile phone market, entry-level mobile phones, once a barren land, are now full of flames of war. 360, which started with software, has now completed the construction of its own mobile phone brand through cooperation with Coolpad. As a subordinate of 360 mobile phone brand, the entry-level mobile phone 360 f4, which has a halo of "design", Wearing an aluminum alloy coat, holding the "safety" sword, and riding the f4 of the eight core fast BMW, can we open up a kingdom of our own in the current competitive market environment? Please follow me into the world of f4 to understand its strength!

[F4 Unpacking] It's thriving, adding luster to youth

The outer package of F4 mobile phone is mainly red (red rice is not red),

On the upper left corner of the front of the package is the logo of the silver stamping enterprise with 360 words, while on the lower part of the package is a letter f and a four dot pattern, representing the mobile phone model. This design is familiar, easy to understand, beautiful and generous, and does not have the common sense of conventional model labeling.

▼ Two packaging labels are printed on both sides of the packaging box (to facilitate access, it is recommended that the user tear off the labels on both sides, keep the bonding at the bottom, and stick the thumb and index finger on the torn half of the label to easily pull out the packaging body).

▼ Open the box cover. What caught my eye was a white mobile phone. It is worth mentioning that. A red label is connected to the rear membrane of the fuselage. Convenient access to mobile phones.

Below the phone are instructions and card taking pins. At the bottom is a 5V, 1A charger, data cable, Sim card pin.

▼ Finally, let's have a family photo.

[Mobile phone appearance]: simple, contains the beauty of design

This time, the author got the standard version of f4. The whole body is white (five colors are available for official sales), the whole machine is clean and simple, and the upper part of the front panel of the phone is distributed with indicator lights from left to right (normally hidden under the panel), cameras, earphones, and sensors; At the bottom of the panel are three hot silver touch keys (is it silly to distinguish the return key from the task key? My fingers are blind, and I always press the wrong key).

▼ In the middle is a 5-inch display screen with a resolution of 1280x720. The viewing angle is up to 178 °, and the screen pixel density is 294ppi. The screen adopts full fit technology. In the era of high resolution screens running horizontally, the screen with such parameters is a bit out. However, in the actual use process, the imaging effect and the viewing angle are both good. After all, the human eye is just the human eye, It can't compete with technology. Another thing worth noting is that if there is a partner who uses VR, it should be carefully considered. This mobile phone is a bit reluctant to use for VR viewing. When watching movies through VR devices, it can see pixels in a grid.

Visual condition of each angle screen

▼ In terms of the frame, f4 uses the metal middle frame sanded by sand blasting process to decorate the CNC high bright edge, which is a good design to transfer the screen to the back cover, In terms of key layout, the phone has a 3.5mm headphone hole at the top, a symmetrical speaker at the bottom (to avoid the speaker being blocked due to the palm or the phone being placed flat) and a data interface (unfortunately, the latest Type-C interface is not used). There are power keys and volume keys on the right. The feedback of key pressing force is moderate, and the feel is good, but the sound of key pressing is a little loud. I hope that the model will be improved in the future, The left side is the card slot position.

▼ The card holder adopts a two out of three design [SIM1: Nano SIM; SIM2/TF: Nano SIM&TF card] (you can choose one card slot to support 4G network, and the other card slot will use GSM network) The front end of the card holder has a "T" type anti dazzle design to prevent the phone card from being damaged due to the wrong insertion method (the phone card can be inserted or removed when the phone is turned on, and the flash memory card needs to be uninstalled and then removed).

▼ The back of the fuselage adopts an arc design, with a frosted plastic back cover. The whole back is only equipped with symmetrical openings composed of cameras, flash lights and fingerprints. This design makes the whole back cover fully present (some articles say that the back cover can be disassembled, but after several days of use, there is still no door open. Is it my wrong routine?) The lower part is printed with the 360 brand logo.

The overall grip of the phone is comfortable, and the opening layout and design are very symmetrical, making people feel that 360 is full of sincerity and sincerity

[360 OS] Smart, free and safe

In terms of system, 360 mobile f4 adopts 360 OS, which is deeply optimized based on Android 5.1

The system focuses on lightness and safety

▼ Phone power on settings.

Available RAM after power on, ROM。

▼ The system has less built-in software and can be uninstalled. And as a mobile phone, there is no mobile company software. This really surprised the author, because the mobile phones I used have more mobile company software built in, which immediately made me like 360OS, and I am really fed up with mobile apps. Like "clean".

In addition, except for Android basic applications, other applications in the system can be uninstalled as you like, and you can play as you want. For such freedom, I give full marks. In terms of application search, 360OS is also more humanized. A search box can pop up when you slide your finger up the screen to easily find applications. In addition, you can switch back and forth between desktop application folders to make your girlfriend never have to find an application again.... Smirk

▼ The biggest highlight of this machine should be fingerprint recognition. Its built-in fingerprint identification system. Five groups of fingerprints can be entered, and any application in the mobile phone can establish association for each group of fingerprints. The speed of fingerprint recognition was almost uninteresting when I first got the mobile phone. After several days of use, the recognition speed was slightly delayed. For the back fingerprint, many people feel awkward to touch the fingerprint button with the middle finger due to finger restrictions. Here, the author gives you a suggestion: divide the finger of the index finger into top, bottom, left, right, and middle five sides, just enough to enter five groups of fingerprints! Easily crack the shortage of thick and short fingers.

▼ Power saving mode. There are three built-in power saving modes. Intelligent power saving. This mode can be used for daily life

General power saving. This mode can be applied to tasks with high CPU utilization, such as playing games, watching large movies, etc

Super power saving. It can be provided when the mobile phone has low power. It is longer and has a long life. In this mode. Any display on the phone will turn black and white. (It can also be used in the night mode in the dark). This is the first time I have seen it.

Pass the trial in these days. F4 mobile phone can be used under normal conditions, and the battery can last one and a half days.

▼ Dial up contacts and SMS integrate some functions of 360 mobile phone guards. SMS provides classification, displays the summary content of SMS on the first interface, and displays the functions associated with the contact number in the SMS input box, which is similar to WeChat public account!

▼ Features ： Built in system, double WeChat. Property isolation system. One card with multiple sizes. Heat source tracking. Use a cold room. And many other black technologies.

① Dual WeChat, the system has built-in WeChat separation function, which provides convenience for users with dual WeChat, and avoids the insecurity risk caused by using online WeChat separation. The author has a deep understanding of this, and will never have to worry about missing girlfriend information because of too much work information in the future.

  ② Property isolation system. To ensure the security of mobile payment, under this system, if you suffer economic losses due to trojans or phishing websites, you can enjoy a single payment of up to 10000 yuan, and a compensation guarantee of up to 120000 yuan throughout the year. Therefore, screenshots cannot be taken in the system. So the screenshot is a picture downloaded from the network.

③ Application refrigerator: For many users, there are many applications loaded in the mobile phone, but some applications are not used frequently. It is a pity to abandon them if they are tasteless. What should we do? 360OS provides an application freezer, which can freeze and store applications that are not used frequently, saving RAM space, so that the mobile phone can run more smoothly. When we need to use frozen applications, it is convenient to unfreeze the applications by tapping them?

④ Location crossing: provide simulation of national and foreign famous scenic spots, which is really a sharp weapon for men and women to wear

⑤ In terms of private protection, 360 OS has a built-in privacy protection space, which supports three encryption methods: fingerprint, dial, and desktop icons. After the password is set, the privacy protection software disappears (no way has been found to close the application and let the icon appear). Without the password, no one can find it. In the future, the phone can be used generously and lent to others. Hum, See how you can peep into my privacy.

Finally, a wave of practical small functions that you may find

In addition, there are other features. Let's get to the f4 quickly!

[Performance] down-to-earth, sufficient daily consumption

In terms of hardware configuration, f4 has built-in MT6753, a mid-range chip of MediaTek. This chip uses eight 64 bit ARM Cortex-A53 processors, with a main frequency of 1.5GHz, and its GPU is Mali-T720. It supports Open GL ES 3.0 and Open CL 1.2 APIs, and can support global full mode networks. However, f4 only supports mobile 4G, which is regrettable.

The following is the score of the running score software

▼   In the ranking list, the score of the evaluation run of Anthare is 35293, ranking 26th, which is relatively good among entry-level mobile phones.

▼ The score of 360's own performance evaluation by Master Lu is 35898; The experience evaluation score is 105; The evaluation score of h t m l5 is 31860

The overall performance focuses on daily use, but running general large-scale games is completely stress free, which will be introduced later

[Photograph] Clear, leaving wonderful moments

In terms of camera configuration, 360 mobile phone f4 uses a 5 megapixel front camera and a 13 megapixel rear camera (the aluminum alloy frame of the camera has a cutting feel, and the details are not properly handled). The front and rear cameras use a large aperture of f/2.0, and the rear camera is equipped with PDAF focusing technology. It is equipped with the new FOTNATION4.0 intelligent beauty function, so that beauty will not be delayed, so that you can take photos as you want.

It also supports 1080p full HD camera Age recognition, filter effect, square Watermark camera, countdown photography, touch screen photography Geographic location recognition, fingerprint photography, real-time HDR SLR mode, night view mode, professional mode Panoramic photography, live navigation, time-lapse photography.

Here is a group of live pictures

▼ Photo mode pictures, clear imaging effect, high color reproduction, leading the shooting ability of the same type of mobile phones

▼ It is not difficult to see the contrast between the night scene and the photographing mode (because the image in the night shooting mode is too large, the original image cannot be uploaded). Under the night shooting mode, the noise is significantly reduced, and the light inflow is also increased.

Left: Normal mode. Right: Night shot mode

Left: Normal mode. Right: Night shot mode

▼   SLR mode

▼ Long shot

▼ The front camera provides age recognition, square, watermark and voice capture Countdown photography, touch screen photography, fingerprint self photography Real time HDR, geographical location recognition, gesture photography Support 1080p full HD camera.

Mobile phone photo function is more than enough for daily life

[Amusement game] It's very enjoyable

In general mode. We tested two games.

▼ One is Battlefield: Rebellion Company 2. It is a conventional game with a size of 756M. In the monitoring of perfMon, the CPU occupancy rate is relatively high, only 41% at the highest time. However, there are many online cores of the CPU, and six of the eight cores are running.

▼ The other is "NBA2K16", 1.9G in size, which is a very large game on mobile phones. During the test, the CPU utilization rate was high, but there were two cores offline at the highest time, which showed that the CPU computing power could still cope with large games.

After the test of two large-scale games, the f4 can easily cope with it. It can be seen that the overall performance of the mobile phone is good. You can play large-scale games as the official publicity of 360 said. If you want to feel the happy gunfight and experience the thrilling cool run, then start with it and let it take you into the game boundary!
