It has been more than a year since the official launch of Xiaomi Mobile 4 on July 22 last year. Xiaomi Mobile 4 is a mobile phone equipped with Qualcomm 801 main frequency 2.5GHz chip, a 5-inch 1080P screen, and a stainless steel metal frame. When it was first launched, it was snapped up on the official website, After one year, the price of the Xiaomi 4 mobile phone has also been reduced to 1499 yuan, which is very popular among rice noodles. As a modern machine cleaning artifact, it can not only use the deeply customized MIUI system based on Android, but also is a classic mobile phone that can brush Windows 10. This is the special version of Xiaomi 4, which was started last year during the Double 11 Festival. In fact, the only difference between this version and the standard version of Xiaomi 4 is that the running memory is only 2GB. Other configurations are identical. I started using this mobile phone in May this year. Later, due to various reasons, I haven't given it a comprehensive evaluation, and I'm still a little sorry. Let's take this opportunity to make a simple evaluation.

·Unpacking&Appearance·

▼ The special version of Xiaomi's mobile phone 4 is still packed in the same kraft paper as Xiaomi, and there is only a big "MI" mark on the upper right side of the front.

▼ The packages of the special version and the standard version of Xiaomi 4 are the same, but you can still distinguish them from the label on the back of the box. The label contains some configuration information about the special version of Xiaomi 4.

▼ The appearance and standard of the special version of Xiaomi mobile phone 4 are the same. As the first metal framed mobile phone of Xiaomi, it was also given the title of "the most beautiful mobile phone of Xiaomi" during the period when it just came into the market. Of course, the title now belongs to Xiaomi note.

▼ The special version of Xiaomi mobile phone 4 uses a 5-inch Sharp/JDI screen, 1080P resolution, 441PPI, high color saturation, and a newly upgraded sun screen.

▼ There is a light sensor, handset and an 800W pixel Sony/Samsung front camera on the top of the mobile phone screen. There is a 3.5mm headphone jack and an infrared transmitter on the top of the mobile phone. This infrared transmitter is also a feature of Xiaomi mobile phone 4, which can turn the mobile phone into a universal remote control in an instant.

▼ There are three white backlight virtual keys under the screen of the special version of Xiaomi mobile phone 4, and there are 45 sound cavity holes and a Micro USB interface at the bottom of the mobile phone.

▼ The back cover of Xiaomi mobile phone 4 special edition is made of plastic material with IMT 9-layer process, 0.06mm extremely fine texture, which can effectively reduce fingerprints. The rear camera of the mobile phone uses a 1300W pixel Sony/Samsung stack sensor, which can focus at a maximum speed of 0.3 seconds, and is equipped with a flash below.

▼ There are volume+/- keys and power switch keys on one side of the special version of Xiaomi mobile phone 4, but the feedback strength of the keys is not very good. It feels stiff when you press them. Although the 1.3mm stainless steel metal trim is beautiful, it is also very easy to have scratches because of the large bevel. Personally, I suggest you use a phone case.

▼ There is a Micro SIM card slot on the other side of the phone, but it only supports a single card, which seems a little less at present.

▼ It's summer, and I just have a wooden back cover of Xiaomi mobile phone 4 in my hand. Hurry to change it for a new one, and feel cool in the hot summer. The wooden back cover and the mobile phone fit well, and there is basically no gap.

·System&Experience·

▼ The special version of Xiaomi mobile phone 4 can be upgraded to MIUI 7 system at present, and most models can experience it now, so we won't introduce too much here. The icon still continues to be flat and extremely simplified. Let's first take two screenshots of the main interface and lock screen interface.

▼ On the "About Mobile Phone" interface of the mobile phone, we can see some configuration information of the mobile phone. Here, we can see that the running memory of the special version of Xiaomi Mobile Phone 4 is 2GB, which is different from the 3GB running memory of the standard version.

▼ Maybe some friends are worried that 2GB of running memory is enough. After the actual test, there is still 450MB of running memory in the cloud after opening 10 APPs. If you are not a hot player, you should still be able to meet your daily needs.

▼ Although Xiaomi has not been competing for points for a long time, the running points can still reflect some performance of the mobile phone from some aspects. Let's test the performance of the mobile phone with Anthare. Xiaomi Mobile 4 Special Edition scored 39954 points after clearing the memory, which is still very good.

·Hide&Features·

Now let's briefly share with you some special small functions I found in the special version of Xiaomi 4. Of course, this is not only available in Xiaomi 4, but also some functions that can be used in other Xiaomi phones. Most of the following have existed in MIUI 6 before, and of course, they can still be used in the latest MIUI 7.

▼ Quickly enter the desktop editing interface: first, use a few quick gestures. Pinch your fingers, and you can quickly enter the desktop editing interface.

▼ Quick access to the desktop thumbnail: you can quickly access the desktop thumbnail interface by holding a three finger pinch gesture on the mobile phone screen, and then we can set the main interface and add pages in this interface.

▼ Lock application: Next, let's give you a small practical function. If you like me often clean the memory, this function must be used. That is to lock the application icon. When cleaning up recent tasks to release memory, ensure that the application is not forced to end running. Long press the Home button to enter the recent task cleaning interface. Select the application icon you want to lock, and then pull down to lock it.

▼ Custom operator icon: Are you tired of the monotonous operator name in the status bar of your mobile phone? In fact, our MIUI can be modified directly. Enter the setting interface, and then select the "Notification and Status Bar" option. After entering, you will find a "Custom operator name" option. After entering, you can modify it, However, if you want to use various trademark symbols, you need to import trademark symbol files and use the corresponding fonts. I usually use Milan and Yan, which can be displayed normally.

▼ Share network password: Our MIUI system has the automatic memory function of WiFi password. Just input it once, and next time you enter the range of WiFi, you can directly click to connect. In addition to this function, our MIUI also has a sharing function. You can know the password of the current WiFi network by a simple scan.

▼ Private photo album: With the continuous optimization of mobile phone cameras, more and more people begin to use mobile phones to take photos, but the security problems of photos that come with them are also attracting more and more people's attention. In order not to become the protagonist of the next event, we'd better take precautions in advance. MIUI system provides us with a private photo album function. We can encrypt some photos that we don't want others to see at will in advance, which adds a layer of security to photos. After entering the gallery, select the Cloud Album option, and then slide down to enter.

▼ Private SMS: Since there is a private photo album, there will also be private SMS. You can put some SMS that you don't want him or her to see in it. This is also a relatively hidden function. After entering the SMS interface, you can enter by sliding your fingers down. The best cooperation between two fingers can increase the success rate of entry.

▼ Divine Hidden Mode: After the setting in the latest MIUI6 development version, there is an additional Divine Hidden Mode, which allows you to significantly save power consumption when the mobile phone power is low. Enter the "Settings" interface, select "Other Advanced Settings", and select the "Power and Performance" option, then we can see the legendary "Shenyin" mode.

▼ Android Egg Game: In fact, many functions in MIUI6 are hidden in the "About Mobile Phone" interface. Quickly click the "Android Version" 3 times to enter the Android Egg Game interface, and then continue clicking the screen to enter another game interface.

▼ Open the developer option: just click "MIUI Version" 4 times in a row in the "About Mobile Phone" interface to open the hidden "Developer Option". Generally, the first thing I do after I get the mobile phone is to open the "Developer Option". Then you can adjust all the options in the animation scaling to 0.5X, which will slightly improve the smoothness of the system. You can try it.

▼ Grab the log log: click the "Processor" option five times in a row in the "About Mobile Phone" interface, and the system will automatically generate a log file. This function should be more useful for members who join the internal test group. Ordinary users can only learn a little about it, but it is not useful in general.

▼ Phone information: Click the "Body Storage" option for five consecutive times in the "About Mobile Phone" interface to enter the "Phone Information" interface, where you can test the phone card information, battery information, usage statistics and WLAN, and see the signal strength of the mobile phone in the current state.

▼ Mobile phone hardware detection: click the "kernel version" option 4 times in the "About mobile phone" interface, and we can enter the cit interface, that is, the mobile phone hardware detection interface. There are 30 detection items in total. Here we can detect some hardware on the mobile phone, and judge by ourselves whether the problem is caused by hardware failure or system, If the detection is not a hardware problem, we can solve the problem by updating the mobile phone system. If the detection is a hardware problem, we have to go to after-sales service.

·Summary·

Xiaomi Mobile 4 has also been released for more than a year, and the special version of Xiaomi Mobile 4 in my hands has also been used for 9 months, most of which are used by my wife, because she doesn't play many games, mainly WeChat, QQ and watching videos. I haven't heard that there is a situation of "stuck". After several rounds of price reduction promotions, the current cost performance ratio is relatively high. If you are not an avid player, in fact, it is good to choose a 5-inch 1080P high-definition large screen Xiaomi mobile phone 4. The 5-inch mobile phone feels just right, and there is no pressure to hold it with one hand. MIUI7 will also be released on August 13. It is said that Xiaomi mobile phone 4 is also on the list of first updates. In addition to MIUI7 system, Xiaomi mobile phone 4 can also be flashed into WIN10 system as soon as possible, allowing you to experience a variety of different operating systems. If you like it, it is a good choice to start now. Of course, you can wait until the new product launch, However, I don't think the price will change much.
