Foreword
For a long time, I haven't sent any post about digital. This time I just got Sony's latest flagship mobile phone XZ Premium (hereinafter referred to as XZP). I believe that the gods have also seen all sorts of out-of-box posts on the Internet for the first time, so I won't go into details. This is my second Sony mobile phone, the first is the Sony Ericsson K750C. The two mobile phones were separated by 12 years, and technological advances are no longer comparable.
For Sony mobile phones, has always been my blank field, before the iPhone party, Huawei glory 8 as a backup machine. This time Sony XZP is considered a very high evaluation this year models, hardware equipped with Qualcomm 835CPU + 4G memory +64GB will not say, in addition to the iPhone, Huawei two home their own CPU, major manufacturers flagship models are basically this configuration, and Sony For the 4K HDR screen and exclusive IMX400 Sensor's blessing, let XZP even more powerful.
Sony (SONY) Xperia XZ Premium G8142 Mobile Unicom Dual 4G Phone Hyun Black 5699 yuan Jingdong to buy Unpacking steps
Open the box 
2. Take out the phone and put it to the side. The lower part of the box is the data cable, earphone, power supply, and instructions. 
3. Carefully appreciate the XZP, taste good, well, of course, is the smell of smell, sip, metal taste. 
A lot of online video out of the box, the above steps are skipped, the key is the third step. 
one. The appearance of a matter of opinion
Sony upholds the design of the Xperia series in the past and is well-placed. There are no arcs in the corners, earpieces (subspeakers) and main speakers (yes, the opening below the screen is the main speaker, and the small hole next to the USB TypeC connector is the main microphone). Symmetrical design ensures that two speakers sound when the screen is landscaped (supports virtual surround sound). The sound is good when watching videos.
XZP screen accounted for a small proportion, there is no follow-up Samsung S8 and millet MIX's full screen (SHARP also out of a few days out of a special-shaped screen, you know), holding the feel with the iPhone 7 plus almost. The back of the mirror design makes people look bright (if it is silver, it is a mirror), but it is also easy to become a fingerprint collector, easy to scratch in daily use, so with shell is still necessary.
Power key integrated fingerprint identification, and the volume size keys are placed on the right side of the screen for easy one-handed control (but for me this left-hander ..... 
)On the left side of the screen is a nano sim card slot. The card slot is designed to be shared by Micro SD card slot. It is a separate type. One of the card slot bottom brackets is embedded inside the fuselage. You need to use your fingertips to click and take it out. Sony does not use a card. The design of the two cards should be waterproof, and you can see a thin rubber ring on the outside of the slot cover. The top of the fuselage is 3.5mm headphone jack and vice microphone, the bottom of the fuselage uses USB TYPE C interface, support QC3.0 fast charge, while the body supports IP65/68 waterproof, anyway, I will not risk losing the warranty bubble Play in the water (wash the screen, showering is still no problem). The upper left corner of the back is the Motion Eye main camera lens and laser focus sensor (also no follow-up dual camera), infrared sensor and flash, the center is the NFC sensor area.
Overall, Sony has always had its own set of design concepts. Instead of following the trend, the company looked at the previous models and felt no significant changes compared to previous models.
two. 4K HDR screen is not easy to use
The fifth-generation Corning Gorilla Glass and 4K screen plus SONY's own 4K HDR display program, a total of standard, professional, ultra-realistic third-grade adjustable, I currently use professional mode, when you need to modify the map to adjust to the standard mode (SRGB color area). As for the ultra-realistic model, individuals feel too bright and use it as appropriate. Although the screen is a 4K screen, the XZP does not display at full 4K resolution, but rather starts 4K rendering under certain circumstances depending on the resolution of the content source. No difference in daily use, science to see the tubing 4K video, display effect is almost a bunker, and I also tested to the phone after copying into the 4K movie playback quality is also hacked days, screenshots can do wallpaper. In addition, the photos taken by a7r2 are transferred to XZP and displayed in the album at 4K resolution. There are also large foreign gods tuned into 4K full-time display, which will result in some applications with small fonts, playable, and low availability.
three. Experience
Flagship standard not pit
Qualcomm 835 CPU with 4G + 64G with, it should be regarded as the standard flagship model in 2017 (of course, there are other manufacturers out of 6G memory and even 8G memory), support dual card dual standby, but does not support telecommunications cards, non-commercial. Flash memory also uses the UFS 2.1 standard, and you don't have to worry about speed being pitted in data transfer. The data cable with USB Type C also supports 10Gb transfer rate (XZP support to 5Gb transfer rate).
For the game, I usually do not play, but also measured the king of glory, fluency image quality without any problem, but played about 15 minutes, the back of the fuselage is obviously warm.
The biggest highlight is the camera
The biggest highlight of the XZP hardware is the 19 million pixel F2.0 Motion Eye camera, using Sony's exclusive IMX400 memory storage stack 1/2.3 inch CMOS Sensor, can achieve 960fps super slow motion video capture, exciting moments at the same time press super slow motion The key may record the video at 960fps for more than 1 second. After testing, it has high playability and can record exciting moments. It is a unique function of Sony.
At the same time, XZP supports five-axis image stabilization in 720P and 1080P video shooting, Steady shot in 4K video shooting, but not five-axis image stabilization. It is found that turning off the Steay Shot in 4K shooting mode will turn the viewing angle to be smaller than that of opening. . Under the 1080p quality contrast video hands on, you see.
In addition, the XZP camera has an automatic predictive shooting mode and automatically takes 4 photos according to the subject for later selection. When using the smart shooting mode, the camera automatically recognizes and adjusts the parameters according to the scene of the shooting object. I use the mobile phone to shoot at the small baby of the friend's house. The lower left corner can even recognize the icon of a baby.
The front camera is equipped with a 13MP F2.0 large aperture, blessing automatic whitening function, face recognition focus, these are standard, manual mode can adjust the exposure compensation, white balance and HDR, camera mode can support Steady Shot anti- Shaking, but the same viewing angle will be a bit narrower than turning off image stabilization.
Measured photographs are still good, and the problem of distortion that exists on the Internet does exist (the iMac below is proof), but it is still acceptable, and can be corrected later in the app. In the night mode, the focus speed will be occasionally pulled by the focus speed in the automatic mode. There are still some smear marks. It is recommended to use the manual mode and fix the mobile phone, otherwise it will be easy to shoot. Viewing the photos taken in the album will be a little blurry. After zooming in, the photos will be shown in more detail. It is inferred that 4K rendering should be performed.
Native system is also OK
About the system is currently the latest Android 7.1.1 (I hope to upgrade Android 8.0), is almost native Android, State Bank version replaces the Google family bucket with Baidu family bucket, the system is very good in terms of fluency. This time, the BNM has saved power-saving features to optimize the app and achieve power savings. Of course, there are hints under this function. If there is an app exception, it does not support power saving. The gods also studied how the Hong Kong bank's firmware saved the country's energy-saving features. In addition to not directly upgrading the firmware, users who prefer to use Google's native firmware have more choices.
Battery life lever
The XZP BNM firmware saved power saving and assisted with the STAMINA power-saving mode, and pro-tested daily usage to 20% electricity at 8pm, which was very satisfactory. On the charge side, QC3.0 fast charge can rush to 50% in about half an hour, and the efficiency is good. After the built-in STAMINA is turned on, the daily experience is not much different, but the Ultra STAMINA mode can only use several basic mobile functions, such as telephone, text messaging, and camera.
Look forward to: Sony Dafa hardware + software both hands must be hard
The hardware configuration and system performance of the XZP made the cable powder amazing. In my opinion, Sony can do even better. The biggest expectation is that in terms of system optimization, in the rise of the national mobile phone brand today, major manufacturers have made great efforts in software optimization, and Sony has almost zero in system optimization. I think that once the software is optimized, it will be unique to Sony. The hardware black technology definitely has a great market competitive advantage.
camera
For hardware, XZP uses Sony's own IMX400 sensor, which has high imaging quality. However, for common continuous shooting, 4K video shooting, and panoramic shooting modes, camera applications exist, and some need to be downloaded separately. trouble. Personally think that Sony can further optimize the camera function software, integrate these camera functions into the camera and camera mode, and for AR effects, creative effects, audio photos, background blur and other camera applications can be retained in the camera application, After all, the frequency of use is not panoramic, 4K shooting, continuous shooting more.
Secondly, there are some system settings in the shooting process that are quite different. For example, the camera has tapped the screen before shooting but only the focus can be selected (automatic metering can be performed). After the shutter button is pressed, the bellows is pulled for focusing (if it is already focused Very fast, focusing shutter at one go), while the photo store has a certain time lag to enter the album preview, compared to last year I bought glory 8, feeling slower fast 1 second (but does not affect continuous single shot), but I I think this can definitely be solved if the software is optimized. In the previous video, you guys took a look. Due to one-handed shooting, the operation is not very good. You can make do with it. The mode used is automatic (focal point is default to the center). There is internal storage of non-SD card (to avoid questioning the SD card speed. Problem causing album preview to be slow
Again, automatic prediction shooting will start when there are many moving objects on the screen. What do you ask me to see? Of course, because this function is activated, the viewfinder screen will be stuck, it is presumed that the camera is already recording photos, but in reality, I just look at the scene. If this sensor's memory storage function is used for continuous shooting, the number of consecutive shots will be more, and the feeling effect will be more direct, and it will also reduce unnecessary computational pressure caused by the automatic detection of moving objects, resulting in the appearance of stuck.
Finally, 960fps super-slow video requires a lot of light, which can cause flickering and smearing of the screen if the room lights. This is only looking forward to the next generation of products for improvement.
other
Fingerprint recognition is fast, but fingerprint payment is not supported. In addition, the screen capture function is very simple, and long-pressing the power button can not be intercepted and edited immediately after the interception is completed. At the same time so far, there is no recording function. (Even Apple's iOS 11 has added screenshot editing and recording capabilities under pressure, and Sony has to keep up with the rhythm.)
Hong Kong Bank firmware? State Bank firmware? Is ROOT?
During the month-long use, the system fluency was good, and both the BNM firmware and the Hong Kong-based firm's firmware I had experience. For BNM's firmware, there are no full buckets such as Google services. Sony's built-in software is also different from the Hong Kong line's firmware. In addition to the "Power Saver," the BNM's firmware can only download software through the official website or other third-party software stores, in addition to downloading via Sony Select. There was an incident of rogue software in the domestic third-party software store. I was cautious about how to download the software and minimize the security risks. It is important to note that some Sony-certified software is still safe in Sony Select, and some software is provided through Baidu at your own risk. Therefore, for example, QQ, Wechat, Weibo and other softwares are downloaded directly from the website of the official website. The software that is not available is then downloaded via "Sony Select", hoping to avoid the possibility of some rogue software being implanted. At the same time, I made serious choices about the system permissions of all installed software. On the one hand, it saves electricity, and on the other hand, it reduces software to read unnecessary private data. As for the Hong Kong line firmware, downloading software directly from the Play Store, the relatively high safety factor, after all, is Google's official product, but can only be downloaded through the scientific Internet access, software that is not really only looking for alternative apps. Secondly, the Hong Kong firm's firmware has no power-saving features and can only be added to this function through the flashing machine, but it is noted that OTA upgrade cannot be performed afterwards (the same applies to brushing VoLTE function).
In short, the two firmware, I eventually chose the Hong Kong line firmware, although it is necessary to scientifically access the Internet, but the relatively safe source of the software is still the first place, and I want to brush the oil pipe, ah, BNM's firmware wants to brush the tubing must first Root Can you run Google service framework and other software... So, consider whether to use Hong Kong line firmware. As for the dark areas and Root strongly suggest it or stay away ... Data security and system stability is still the first, there is no need to go to achieve some special features and risk (may be heavy), reminds me of the year with the geek rabbit 2 into the brush each The period when the modified firmware was finally brushed into bricks.
Four. Summary, with an attached egg
As an iPhone handset party, the general feeling of Sony XZP is that the hardware is very powerful, and the experience is still good, but the software owes the ignition. For example, go to the SONY Mobile official website to download the SONY Communication application and the 404 page not found. Dragon. I hope that Sony will be able to link the Playstation with a mobile phone and link it with SONY TV to apply the 4K HDR TV display technology and the camera 5-axis image stabilization technology to the mobile phone. It will optimize the system's other core functions and make the powerful hardware configuration equally powerful. The software platform does support.
