Hammer Smartisan T2 It is a very controversial machine, together with a large number of hammer powder hammer black and water army, which makes it difficult for ordinary users to have a clear understanding of the machine itself, so I hope this evaluation can show you a complete and comprehensive Smartisan T2.
This evaluation report, in addition to the conventional screen, performance, photography, sound quality and endurance, focuses on the appearance and Smartisan OS Conduct analysis.

Appearance and workmanship
T2 is packed in a pure black paper box, with accessories including charger, power cord, instruction manual and card taking pin.
The left is the nut mobile phone package, the right is the T2 package
The package of T2 is almost the same as that of the lower grade nuts, but the relevant labels have been changed and the color has been changed to black.
The charger is also 5V1.5A and does not support fast charging. For a domestic mobile phone starting at 2499 yuan, this is really not very kind. It is no wonder that many media have criticized T2 for clearing the inventory of accessories for nut mobile phones.
The appearance of the two generations of Hammer phones is not different. They are also sandwich designs that pay tribute to the iPhone 4. The main changes focus on the metal frame and 2.5D glass. The forehead and chin are relatively wide. The metal frame is thicker than other phones outside the wide black edge of the screen, making it one of the few Android phones that can compete with the iPhone.
The official said that the white version would not be launched. In addition to the fingerprint absorption feature of the glass, T2 is also called a phone with fingerprints but no identification. Virgo may not be able to stand it, but the author, a hearty user, does not feel too uncomfortable.
The camera is on the left side of the forehead, and the light/distance sensor is integrated on the right side of the earpiece. The simple layout makes the broad forehead seem very open.
The physical buttons on the chin have large left and right positions, and the pressing feel is slightly hard. According to netizens, there is slight difference in the feel of the three buttons compared with the machine on our hands. Although it has little impact on the use, you need to be prepared before buying.
The logo of the camera and the metal patch in the middle is slightly lower than the glass, and the English logo is printed on the inside of the bottom glass. 2.5D glass is really beautiful, but it is slippery. Please be careful when putting it on the table.
On the top are noise canceling microphone and headphone connectors.
In the bottom symmetrical mesh, the microphone is on the left and the speaker is on the right. The flagship mainstream Type-C interface is not used.
The volume and brightness buttons are symmetrically placed on the left and right.
The SIM card slot is hidden below the volume key. The card holder is simple and exquisite in design. The built-in spring allows a larger tolerance and keeps the volume key tight. The empty position of the key in the card slot is even smaller than that on the left. Some netizens said that the left and right volume keys have different feel and tightness, but the machines we got are quite similar, perhaps due to the difference between batches.
It is worth noting that the card slot has high requirements for SIM cards. One of the two telecom cards cut into nano SIM size by the author cannot be identified. Users need to pay attention when purchasing and using them.
The matte grain of the metal frame without breakpoint is very large, and the matt effect is obvious, with a slight radian.
Seen from the drop scar, the coating is relatively thick, and the risk of paint dropping is small. The rear metal and glass are directly combined, and the workmanship is very good. There is no common "plastic washer". The structure and vision are much simpler and more capable than those of the previous generation, but the risk of screen breakage is high when falling.
Both T2 and T1 are 5-inch screens, with reduced thickness and weight, and slightly increased length and width due to the addition of metal frames (T1 is 141x67.74x8.23mm, 167g; T2 is 144.55 * 70.84 * 7.53mm, 146g). The weight is obviously lighter, the small body and the rough matte metal frame make it hold and feel significantly improved.
When operating with one hand, the center of gravity is seriously lower, so be careful when flying out
T2's industrial design and workmanship are worth praising. If you really want to find fault, the wide forehead, wide chin and horse racing frame are one, and the solid button on the chin is the biggest appearance and experience failure in the eyes of the author:
The physical button destroys the simplicity and beauty of the front, which is easy to hide dirt;
After the home key incorporates the power key function, the problem of service life will become more obvious;
It has a strong sense of separation between touch screen and physical keys;
The physical keys need more force to press, plus the front and back glass that is as slippery as soap, pay attention to the single hand operation;
Finally, there is a paradox in the design concept: try every means to remove the card slot and signal partition strip on the side, but there are three physical keys on the front

The T2 screen is also identical to the T1 screen, which is a 4.95-inch 1080P IPS screen with 445PPI supplied by Sharp. In addition to the thick protective glass, which slightly affects the screen fitting effect, the overall performance of the screen is excellent:
The highest brightness and backlight uniformity perform well: the highest brightness is 501 nits, and the corner brightness is between 479-493 nits;
The color temperature is obviously cold: in the default mode, the color temperature fluctuates between 9900K;
Excellent color standard performance: the average Delta E is 1.61, the highest value is 5.87, and the lowest value is 0.48. In contrast, the Delta E of the iPhone 6s is 1.09, and the basic mode of the Galaxy S6 is 1.6.
performance
T2 adopts the scheme of Snapdragon 808 with 1080P screen. The performance configuration is not flagship, but it is better than balance. Snapdragon 808 code MSM8992, CPU part is dual core [email protected] +4-core [email protected] , GPU is Adreno 418@600MHz (instead of the nominal 625MHz on the official website of Hammer). 3GB LPDDR3@933MHz Memory and 16GB/32GB Emmc5.0 storage (TF card expansion is not supported) are mainstream configurations.
Use Qiku's flagship mobile phone, Xiaomi 4c and LG G4 also equipped with Snapdragon 808, as well as Note5 equipped with Exynos7420, LeEco 1 Pro equipped with Snapdragon 810, and Xiaomi Note equipped with Snapdragon 801 as performance comparisons:
CPU computing ability test
GPU graphics performance test
Continuous read/write speed test of flash memory (affecting large games and applications but loading speed)
In general, hammer Smartisan The performance of T2 is the normal performance of Snapdragon 808, and it will win or lose with the flagship version of Qiku mobile phone, Xiaomi 4c and LG G4 which are also equipped with Snapdragon 808. The overall performance is better than the previous generation Snapdragon 801 and weaker than the flagship Snapdragon 810 and Exynos7420 of the same generation. Although it has not reached the real flagship level, its daily performance is more than enough.
photograph
Photo taking interface: Smartisan T2's camera app hopes to provide a photo taking experience as soon as you pick it up. The interface and functions are very simple, including HDR/Night View/Panorama mode. There are only 10 settings (in the middle of the figure above), including QR code and business card scanning functions.
Photography experience: the machine has smooth shooting, normal metering performance, and slightly slow imaging speed, but T2 has no phase focusing function. The daytime focusing speed also has certain disadvantages compared with the current thousand yuan machine with phase focusing; The weak light is hard to focus, and the phenomenon of pulling the bellows is serious. Fortunately, the final film rate is still high.
Parameters: Smartisan T2 adopts 13 million pixel rear camera, which supports optical anti shake and f/2.0 aperture. The sensor model has not been officially announced, but its previous generation was Sony IMX214, and it does not support phase focusing, so Smartisan T2 is likely to add optical anti shake on the basis of IMX214.
Performance prediction: IMX214 is a common configuration in the domestic flagship last year, while some models such as vivo Xshot and Moto's Nexus 6 are additionally equipped with optical anti shake. The sensor itself is 1/3.06 inch, and the unit pixel size is 1.12 μ m. The latter is the same size as the IMX278 arranged by RGBW and the IMX234/240 of 16 million pixels.
Comparison object: Nexus 6, the flagship of the previous year, is compared with one plus two, the domestic flagship of this year. The former is the optical anti shake IMX214 (probably the same model as T2); The latter is OV 13860 with 13 million pixels. The sensor area is 1/2.6 inch, and the single pixel size is 1.3 μ m.

Metering: slightly dark during the day; Under weak light, the metering light is slightly bright, and the brightness is much higher than that seen by the naked eye;
White balance: The Smartisan T2 has a very obvious and serious bluish color, which will be very obvious on gray objects, while red objects will change color directly, which is a problem that many thousand yuan computers may not have;
Daytime discrimination and noise control: It is better than the previous generation flagship Nexus 6, but there is still a significant gap compared with the current generation flagship One Plus Two;
Weak light discrimination and noise control: noise control is better than the previous generation flagship Nexus 6, but the discrimination is not as good as the latter, and the gap between one plus two is even more obvious.
In general, the Smartisan T2 photography performance is satisfactory. The daytime and noise control are good, but the weak light performance has not caught up with the flagship of the previous generation with optical anti shake. In addition, the white balance has a very serious blue bias, which greatly affects the actual appearance. I hope the official can fix this problem as soon as possible.
tone quality
Smartisan T2 has placed one Texas Instruments OPA1612 operational amplifier chip (T1 is OPA2604) for the left and right channels respectively, but it still does not carry an independent DAC chip.
As compensation, Smartisan OS has built in Dirac HD Sound filtering digital processing technology. The system has built in acoustic models for special tuning of some earphones, and software corrections are made to frequency/transient response and sound pollution, hoping to give full play to earphones/speakers.
The Apple EarPods with the system's built-in tuning library is used for testing, and the actual effect is quite regrettable. The Smartisan T2 dual op amp brings a very obvious boost, which is much stronger than ordinary mobile phones There is a clear gap between the mobile phones with independent DAC chips such as vivo series, Xiaomi Note and PRO5. If the earphone used is not in the tuning library, the difference can even be recognized by one ear.
Endurance&fever
The battery capacity of the Smartisan T2 is 2670mAh, 18% of the power is lost for half an hour of games, and 6% of the power is lost for half an hour of network browsing. The performance is not good. The 2670mAh battery is really hard to deal with Snapdragon 808 and 5-inch screens.
Only allow WeChat to start automatically in the background, enable wifi without sim card, and power down 4% after 8 hours of standby; When the mobile data and wifi are enabled by inserting the card, 8% of the power is lost in the 8-hour standby mode, and the power is lost in the standby mode. The overall endurance performance is poor, and it is recommended to keep mobile power for daily use.
Charging function test of original charger, Meizu and anker quick charger
The charging speed of the Smartisan T2 is a very serious problem. In addition to the lack of fast charging, the original 5V/1.5A charger can only run at 5.1V/1.3A, and the charging power is not even as good as that of the machine four years ago. In addition, third-party and other brands of fast charging heads also failed to provide more than 5.1V/1.2A charging power
It takes 2 hours and 38 minutes to charge 0-100% of the machine. Even on the low-end machine, the performance is very ugly, and there is a huge gap with the flagship positioning of Smartisan T2.
After running NBA2K15 for half an hour, the maximum temperature on the front side appears on the left side of the three entity keys, which is 44.8 degrees; The highest temperature on the back appears near the volume down button, which is 44.3 degrees. Although the heat transfer between glass and metal materials is fast, the actual feeling is between warm hands and hot hands, but the temperature control is quite good.
system
Smartisan OS was first released on March 27, 2013 (known as Hammer ROM in the early years), and was available for download in June of the same year. The most pure Smartisan OS will wait until the release of Hammer T1 and Nut mobile phones. With the release of Smartisan T2, the version number of Smartisan OS has also been updated to 2.5.
The evaluation of this system by different users is very polarized. People who like it say that its functions are warm and practical, while people who hate it feel that it is an "old man ROM". After more than two years of development, it is not as rubbish as Hammer Black said, but certainly not as magical and useful as Hammer Powder said.
It is the most important selling point of the Hammer/Nut series mobile phones, which is not one of them. Therefore, this evaluation uses the largest space to restore a real Smartisan OS.
System UI and logic
Lock screen, desktop, setting page
Notification bar, shortcut button of notification bar, multi task page
Smartisan OS is famous for its rich and exquisite animations. The system has many things to learn from iOS6, which was supposed to be a physical benchmark in the past: the system interface on a gray white background, the multitasking interface called by double clicking the home key and the music player on the left, the browser layout and note modeling on the familiar side.
The operation logic of this system is different from that of its peers:
All of the three Android King Kong are solid keys;
Double click the home key to call up the task manager;
The setting key is reserved to call up the drop-down list globally. Because the set key is used infrequently and everyone has the habit of pulling down from the top, this key is rarely used;
In addition to the volume key on the right side, there are brightness up and down keys on the left side, which can realize practical advanced operations such as screen cutting and song cutting, and quickly opening applications.
System functions and details
9 The GOOGE desktop is the most complex component in the system. Even the MIUI in its heyday, the desktop functions may not be so detailed:
Imitative icons and animations with a large number of redraws and unlimited details;
The concept of using separate pages instead of folders;
Fast switching in 36 palaces (and above), and applications can be opened directly in multiple palaces;
Applications can be automatically arranged according to the icon color system;
Scan screen to remove corner marks, hide corner marks, hide desktop, etc.
It is worth noting that although the official launch of the Hammer desktop app, the Hammer mobile phone cannot replace the third-party desktop, at least not before root. If users like the hardware of the machine but don't like the desktop, they should pay attention before buying a mobile phone.
Screenshot function, alarm clock, camera that will display direction when shooting horizontally
Imitated materialized notes, calendars, timers also Imitated materialized
One page weather app, recording recorder, traditional music player with interface
There are many detailed functions of the system:
The system has its own thumb to pull down and hover;
It comes with screen recording, scrolling screenshots, framing and graffiti functions;
There are video/GIF editors in the gallery;
Delay sending of SMS and recording of recorder;
When taking a horizontal picture, it will show which direction is up, with its own QR code and business card scanning;
The flashlight will call the light sensor to prevent the flashlight from being opened in the pocket by mistake;
Each alarm clock can see the time from the alarm;
The new remote assistance is simple and easy to use. The sound and picture under wifi are timely and smooth, but only the hammer mobile phone can be used temporarily. See our previous videos for details (starting at 5:40)
Although there are many small innovations, the system will make people feel incompatible when used. Many application functions have been specially enhanced, but there are still many functions to be added to the basic applications, such as:
There is no temperature curve for weather application;
Unable to control the volume of alarm clock;
The location of shortcut buttons in the notification bar cannot be customized;
The notification bar cannot be slid left or right to switch between the notification and shortcut button interfaces;
No harassment, interception, etc.
Deep hidden background bootstrap
In addition, there are many details like semi-finished products:
The necessary auto start control in China has been deeply accepted, and normal users can not find it at all. By default, almost all applications except Weibo and WeChat are blocked. The third-party alarm clock and calendar are killed in the background, and they can't work normally without knowing how to save them;
There is no file manager in 22 basic applications;
When the player is playing songs in the background, there is no control button in the notice bar; When the third-party player plays songs, the shortcut button is also folded by default;
The so-called change of desktop theme is just a change of desktop background
The multi task interface treats the installation page of each application as an independent task, which should be manually deleted after installation;
Press Return after installing the program, and you will be forced to return to the desktop;
The voice assistant, whose practicability is still very low, is always forced to appear in the notice board and music;
The built-in alarm clock application animation is too many and cumbersome. After opening it, it will take 1 or 2 seconds to load it;
The alarm clock list cannot be edited directly. The timer can only be accurate to the minute and can only last for 1 hour.
What is particularly intolerable is the disordered setting list: the first level setting items are incredibly long and arranged in disorder; The screen is automatically rotated and the multi language is used at an extremely low frequency, which actually occupies a single line (looking at many national flags, but there are only five kinds, namely, simple and complex, Britain, Japan and South Korea).
In addition to the over materialized, wired and huge Jiugongji desktop, which the author does not like very much, the system also has some personal preferences, but not very pleasant mandatory settings. Of course, whether you like them or not varies from person to person:
As the essence of Android desktop, the desktop plug-in function has been canceled, and there is no clock and weather plug-in;
Unable to change the real theme;
The photo sound cannot be turned off and the resolution cannot be selected;
The desktop wallpaper is forced to blur. Except for the instant of unlocking, the wallpaper is almost invisible
Compared with Xiaomi, Meizu, vivo, OPPO, Jinli and other old manufacturers, the number of iterations and personnel input of the hammer system is still too small. In addition to the performance of the setting menu, the internal logic has not been completely unified, and there are even contradictions. For example, as an easy to use system, why are there so many hidden/hidden functions such as double clicking the home key, double finger zoom on the desktop, dock bar sliding, and extremely hidden self starting management? There are many ways to play the extra entity combination keys, but these are against the principle of easy use.
Fluency
The Smartisan T2 performs well in the conventional continuous read and write test of flash memory, but its performance in the random read and write test that has a great impact on the use experience is not even as good as that of the previous generation flagship model.
In the random write speed statistics collected by netizens, the performance of Smartisan T2 is the lowest level (3 on the left of the above figure is our test machine), which is far lower than the LG G4 equipped with the same SoC, or even worse than T1. This achievement is directly related to system optimization. The occasional unknown stuttering of the system in actual use is probably related to this poor achievement.
In addition, Smartisan OS has a special negative score optimization. After some score running software is detected, the system will automatically lock into a single core minimum frequency. In the process of routine score running, the machine has a bug that the lock screen will be stuck. After restarting, the system will still be stuck in the negative optimization mode. You need to re-enter the score running app and exit manually to "detoxify". To prevent users from scoring, a blacklist is specially made. Although it is not of any substantive use to users and occasionally causes trouble, it is really an important manifestation of the hammer's "paranoia"
Snapdragon 808+3G memory should have no concern about fluency, but the hammer subsystem occasionally has problems such as stuck, multi task interface animation frame dropping, alarm clock application reloading, etc. In addition, the most frequently used entity There is a delay of a few tenths of a second when you press the home button and the return button. It's hard to make you feel as happy as a flagship.
Coupled with the slow and gorgeous preset animation, it can not be associated with the word "fast". Users who are used to the real flagship speed or are familiar with smart phones should not have too much hope for the speed of this system.
To sum up, this is a system with rich personal preferences (Laoluo team). Many applications have special and thoughtful improvements, and the overall usability is high. However, there are still many missing functions to be added, which makes people feel that the overall function planning has not been completed, and there are many advanced functions mixed in. In fact, the fluency is OK, but there is still a certain distance between the speed and his flagship.
summary
The following is a summary of the conclusions of this evaluation. The project weight can be determined according to the needs, hoping to give readers interested in T2 a general understanding:
Accessories and packaging: the packaging and accessories of middle and low-end machine nuts are almost used, and the power of the charger is too low and not too generous;
Appearance: Some of its design and workmanship are worth praising, but the extra physical keys are not easy to use;
Screen: This is a 1080P screen with excellent brightness, color accuracy and other performances, except for the high color temperature;
Performance: Although it does not reach the real flagship level, its performance is fully adequate;
System: Both the UI and the functions are very distinctive, but compared with the customized ROMs of MIUI, Flyme, futouch OS and other domestic manufacturers, the overall ease of use and smoothness have no advantages.
Photo: The comprehensive performance can catch up with the normal level of the previous generation flagship, but it is still a long way from this year's flagship;
Sound quality: It has great power and software tuning, and its performance is obviously better than that of ordinary mobile phones, but there is still a significant gap for mobile phones with independent DAC;
Endurance and heating: poor endurance performance, no fast charging and worrying charging speed. These two are serious shortcomings, but the heating control is good.
Price: For a Snapdragon 8081080P screen with moderate photo performance, poor endurance, and no quick charge and fingerprint identification, the price of 2499 is indeed on the high side
Personal feelings about machines
It may be because the company is small or out of time. The Hammer mobile phone always has a gap with the real flagship. It has just made up for the metal body, optical anti shake and All Netcom that the peers had a year ago, and fingerprint recognition and fast charging have been popularized in other flagship and even low-end computers. These regrets will have to wait for the T3 next year to make up.
Obviously, this is a mobile phone that has been made with great intentions, but the design of various paranoia is good and not good, and whether it looks good or not is another problem. Smartisan OS always makes you laugh at one or two places when you use it. This is a complex of contradictions. There are many small innovations in functions, many stubborn places in design and functions, and advanced and simple functions coexist.
However, young users may feel a sense of incompatibility. To sum up the reason, it may be because it is a system tailored by Lao Luo for himself and his engineers, which is different from the needs/perceptions of normal users. With this assumption, Geek flavor features such as notes with markdown grammar, various shortcut key operations, tape recorders that can be managed, and N-Palace desktops will become more natural.
Extending to the appearance, why the front and back glass? Why 5-inch screen? Why such a huge icon? The answers to these questions may only be Lao Luo's personal preference, and he happens to be a middle-aged, presbyopian, fat man with a small hand and a small height.
The configuration and experience of Smartisan T2, at 2500 yuan and below, have too many competitors to choose from. The Smartisan T2 is also a machine that needs to be filled with feelings. But for the industry, it is always good to have one more manufacturer; As a consumer, it is always good to have more choices. Although the author will not and does not recommend that you buy T2, the next generation should still have hope.
