As a new comer, 360 mobile phone gave me the impression that it was only a 360 mobile phone. I haven't touched 360 mobile phone before, but I am very interested in 360 mobile phone. In today's brutal market, which depends on hardware and price, 360 F4 is not much better than similar products in terms of price and hardware, but this phone from 360 is destined to have a different side from previous phones. With the increase of Android users on the Internet, the virus and vulnerability time for Android users has become increasingly prominent, which is why 360 joined the mobile device as a battleground in the urgent need for security. From Qiku to Dashen, 360 mobile phones have stumbled. In the face of the mixed low-end market, the emergence of 360 f4 has undoubtedly become a shot in the arm for the thousand yuan mobile phone market, so that users can feel the security guard while purchasing mobile phones.

=Product unpacking=

The outer package of F4 of 360 mobile phone is designed in red and black, and 360LOGO and F4 product name logo are simply printed on the front of the red shell. According to the information marked on the black bottom shell on the back, we can know that there is a white mobile phone lying inside. According to the configuration information, we can see the 2GRAM+16GROM parameter, which indicates that this is a standard F4 for 599 yuan.

The interior of the product is arranged separately. The top is the mobile phone layer, but there are paper materials hidden in the interlayer at the bottom of the mobile phone, and the bottom is the charger and data cable.

The standard configuration of the 599 yuan version is as follows: warranty card, manual, charging head, data cable, mobile phone, card pin. Because most users care about random earphones today, earphones here do not appear as standard configurations.

The beauty of a thing often depends on its sense of symmetry. The 360 F4 phone has a fully symmetrical design on the front, giving people a feeling of beauty, neatness and orderliness. Users with aesthetic obsessive-compulsive disorder can be fearfully cured. And it makes the whole machine look more simple, and the white body also gives a little fresh feeling.

There are hidden breath lights, front facing cameras, round earphones, and light distance sensors on the top of the mobile phone from left to right. The small improvement of the round earphones, in addition to aesthetic considerations, also focuses on the sound quality of the earphones. The three virtual buttons at the bottom adopt the internal silver stamping process. The small dots on both sides of the big circle in the center are used for the best symmetrical design. However, there is no LED backlight inside the button.

The top and bottom metal frames of the mobile phone adopt a symmetrical partition process. A 3.5mm audio jack is set at the top near the right partition, while the middle area of the bottom frame is a Micro USB interface. The two interfaces are symmetrically opened with five round holes for microphones and speakers. This design may be a tribute to Apple in the era of Jobs.

The two metal keys inlaid on the right side of the fuselage perfectly match the metal frame, and the press feedback is also very clear; However, the obvious bulge is somewhat scrupulous for friends who don't like to wear a condom, which is negligible for users who wear a condom.

There is no special design in the card slot design. The tray supporting dual cards can choose one card slot to place the mobile 4G card. Because the SIM2 card slot is designed for the sharing of SIM card and TF card, when users need to use TF card, they need to give up the use of SIM2. Therefore, users who have two SIM cards and want to use TF card have no solution. However, VoLTE high-definition calls are supported, which will bring users a better call effect.

The 360 F4 is designed as an integral part of the whole machine, while the back cover is the same white as the phone panel. The back of the micro arc is matched with a skin like treatment, providing users with a good grip and a good fit to the palm design. The 360 LOGO below the back cover also embellishes the open shell.

The top lens arrangement is also very particular. The outer layer of the lens and fingerprint identification area is clearly delineated with silver white metal, so that the mobile phone can be upgraded in the cheap plastic texture. Not only that, the round flash lamp sandwiched in the middle can not only provide a good light source in the process of taking pictures, but also properly distinguish the two at a suitable distance.

=Hardware&Performance=

360 F4 is equipped with a 5 inch screen with 720P resolution, and the PPI is 294. Although the 720P resolution is not high, due to the full fitting process, the reflectivity of the panel glass is relatively low and the visual range is good. As the viewing angle becomes larger, the screen brightness attenuation and color distortion are controlled within an acceptable range. Compared with 1080P, the power consumption is reduced, making the whole machine have a longer life.

In terms of hardware, 360 F4 is equipped with MediaTek's eight core 64 bit processor MT6753+2GB running memory, with excellent performance. As an entry-level SoC MediaTek MT6753 last year, it has obvious advantages among chips of the same level. According to the running points of Anthare 35326 and Master Lu 34732, the results are quite good, and in the fluency test and HTML5 test, 360 has achieved higher scores than the mobile phones with better configuration or the same kind. It can be seen that 360 has made great efforts in the system fluency experience.

360 F4 video processing chip is equipped with GPU Mali-720, which has been mostly used in low-end computers since its release in 2013. Through the Anthare video test, from the test results, it still performs well in video playback and decoding, but it is not enough for 4K video and partial partial gate format playback. However, compared with ordinary users, it is enough for them to cope with the situation. Even the HD audiophiles will not use their mobile phones as players.

By using professional game performance testing software and testing scores in different modes, 360 F4 can cope with various popular large and medium-sized mobile phones; Even large-scale 3D mobile games can be presented to users smoothly.

=System&Security=

Whether a mobile phone is easy to use is directly related to the mobile phone system in addition to the strong hardware; Nowadays, many mobile phone manufacturers have tailored appropriate systems for their own mobile phones. At first sight, the 360os system did not bring much surprise to people. The icon style of the system itself is also very common. The flat style has a little ink color, and the splash like lock screen wallpaper has a great contrast with the dusty desktop. The top menu bar and the notice bar are displayed in the native system, and all menu functions are displayed in the secondary sliding mode.

360os supports digital unlocking, drawing unlocking, fingerprint unlocking and other methods in the aspect of unlocking screen; The most convenient is the fingerprint unlocking function. Whether the screen is on or off, touch the fingerprint identification module on the back to enter the system immediately, and the identification process can be completed quickly at the moment of touch. However, there is another interesting setting in the password unlocking state. When the number of password errors reaches 3 times, the system will secretly call the front camera to capture the face information of the current operator, and will lock the phone according to the number of attempts to prevent the phone from being broken.

If you don't have the habit of setting lock screen password, the built-in system also does a good job of personal privacy and mobile phone security. Due to the deep integration of 360 security software, users can easily achieve mobile phone location tracking through the binding of 360 cloud service accounts and mobile phones. In terms of privacy protection, applications, pictures, videos, files, desktop icons and even dials can be encrypted through privacy space programs, and no trace can be seen under the desktop and directory. The application lock is applied to the application. If you want to use the application, you only need to enter the preset password and fingerprint.

In addition to the above functions, a directory named "Black Technology" is specially prepared for users in the 360os system. However, let's experience how "black" the black technologies in this directory are. The first is the separate management, which is believed to be well understood by everyone. Users can open WeChat in a virtual way. However, compared with some third-party software, 360's separate management is not so dark. One card with multiple numbers enables users to support multiple virtual numbers through the network. The annoying harassing calls caused by phone information leakage can be regarded as a killer. A virtual number can be created for users to take a taxi and purchase online for 5 yuan per month. Red packet reminder can monitor the dynamic status of red packets in WeChat, Alipay, QQ and other applications and remind users that they no longer have to worry about missing every red packet.

However, my favorite black technology should also be location traversing and heat source tracking. Every time I see my friends on Weibo and in the circle of friends, I can only sit in front of work. Once I have a location, I can pretend at any time and anywhere. By means of virtual location, you can also leave your desired geographical footprint on different application platforms. 360 F4 really helps you to pretend easily. However, the mobile phone fever is also a headache. Through heat source tracking, an alarm will be sent when the mobile phone exceeds the safety alert temperature. Users can quickly find out the application that caused the fever and kill it through searching, so that the mobile phone has reached its best operating state.

Due to the openness of the Android system, even if security precautions are taken in other aspects, mobile payment is still very worrying. As a well-known security enterprise in China, 360 will not shame the location of 360 F4. In order to solve users' worries about payment, 360 OS has specially added a property isolation system. This function can isolate a completely closed independent space in a complex system environment, eliminate all insecurity factors, and provide 360 F4 users with up to 120000 annual compensation property security insurance. It can be seen that 360 has great confidence in this system.

=Photo experience=

In terms of camera configuration, 360 F4 adopts a 5 megapixel front camera and a 13 megapixel rear camera with F/2.0 aperture front and rear, and the rear camera is equipped with PDAF focusing technology. In addition, the new FOTNATION4.0 intelligent beauty photography engine is built in, so that you can automatically enjoy the beauty function in real time during the photography process. In addition, the built-in professional mode and night view mode can make users shoot better under complex conditions. In addition, for the first time, the SLR mode has been added, which is said to be able to shoot the virtual effect of the SLR.  

The camera effect of F4 is reflected from the following sets of samples. Whether in outdoor sunlight or in tunnel light, the photos taken are still in place in terms of color processing, which can clearly show the details of the things taken.

=Experience summary=

Through experience, I have a certain understanding of the appearance, performance and configuration of the 360 F4 mobile phone. The moderate size screen gives people a good grip. The ultimate symmetry aesthetics and excellent feel also give the product a lot of points; In addition to supporting fingerprint payment, it also uniquely enables a more secure property isolation system, allowing users to more effectively avoid snooping programs when operating funds. Not to mention the location traversal, split management, one phone with multiple numbers and other black technologies that are unheard of on other mobile phones, we can see that 360 has made great efforts in user experience. Whether you are a student or a business person, whether you use it as a host or as a backup, the 360 F4 mobile phone worth 599 yuan is very practical. After all, people's functions and prices are clearly marked there.
