Nowadays, in the mobile phone market with dazzling array of new products and fierce competition, Samsung mobile phones have won people's favor with their exquisite craftsmanship, modern appearance and outstanding quality. However, due to the proliferation of parallel imports of Samsung mobile phones, many buyers either flinch before buying or fall into the trap set by JS.

so, in the market where Samsung's parallel imports cross-flow, how can we distinguish between the straight line, the parallel line and the water reform machine? How to distinguish original parts from counterfeit parts? This is the main idea of this paper. The superficial experience is that most people know little about Samsung's so-called common sense of straight line, water line and water reform machine, and there are even some misunderstandings. Therefore, before the topic of this article begins, it is necessary to introduce the basic knowledge about Samsung mobile phone's forward line, water line and water reform machine.

There are always different opinions about the classification of Samsung mobile phones. From the point of view of whether the products are in normal entry inspection, Samsung mobile phones should be divided into four categories:

First, authentic licensed products (line A), that is, the so-called genuine products, refer to mobile phones that are produced in South Korea or Tianjin, have passed the normal entry inspection and the certification of the Ministry of Information Industry, and are officially sold in the market;

Second, parallel imports, that is, products that have entered the mainland through smuggling, failed to pass the certification of the Ministry of Information Industry, and have no network access license and quality guarantee. Parallel imports can be divided into two types. One is parallel (line B), which is strictly licensed. However, due to smuggling into the mainland, there is no network access certificate. However, due to the nationwide warranty of manufacturers, this kind of mobile phone can also be guaranteed for maintenance. The other is Hong Kong banks, which, as the name implies, refers to the licensed products sold by Samsung to Hong Kong, Singapore and other places. Due to the price difference between the mainland and Hong Kong markets, illegal JS is sold to the mainland market through smuggling. Because there is no network access card, Hong Kong banks can not get warranty protection in the Mainland;

the third is the water reform machine. This kind of mobile phone is usually called authentic parallel imports. This kind of mobile phone was originally sold to Europe and America, and smuggled into the mainland. JS turned its English software into Chinese software (plus Chinese font), making it a Chinese-supported mobile phone sales. Because the Chinese font occupies a part of the memory used for other functions, the mobile phone may "sacrifice" some of its original functions. Moreover, there may be a little bug at first. But with the upgrade of the software version, small bugs can be solved. The quality of the water reform machine itself is still trustworthy, so consumers don't have to worry.

here, the author wants to clarify a misunderstanding about the water reform machine. Some people call this kind of mobile phone a revision machine, which is really inappropriate. From the dialectical point of view, the so-called revision should be divided into soft and hard. The water reform machine is a mobile phone that changes its original software without making any changes to its hardware. If the hardware is changed, it should belong to the trigger in the second mobile phone mentioned later in this paper.

the fourth is the assembly machine, which is mostly assembled in Guangdong, so some people list it as a kind of parallel imports. The author believes that according to the general rules of the industry, this kind of machine is not strictly parallel imports from the final assembly place and sales channels, and it should not be included in the category of parallel imports;

the fourth category is the second mobile phone. This kind of mobile phone can be divided into three types: refurbished machine, pure second mobile phone and trigger. Refurbishment is to sell second-hand mobile phones as new machines by changing the shell and cleaning up the appearance. The trigger is to upgrade a certain part of the mobile phone to a high-model mobile phone through hardware transformation such as replacing parts, such as converting Siemens 3518 into 3568, etc., and there is no guarantee in quality at all. As mentioned above, many consumers who want to buy parallel imports but are afraid to buy them are afraid of encountering assembly machines and second-hand phones, especially the latter.

so, how can we tell the difference between a straight line, a water line and a water-changing machine?

any concrete thing has both internal and external attributes, and it has a special essence, that is, personality, which is different from other things, but it also has the same essence as other things of the same kind, that is, * * *. Because the individual contains the general and generally exists in the individual, people can guide the overall work by mastering the individual typical and finding out the regular things with the same * * *. This method of understanding and working summarized from practice is also applicable to the identification of Samsung mobile phones without exception.

in fact, as long as we pay a little attention, we will find that whether it is a Samsung bar model or a flip phone; Whether it is a black-and-white screen or a color screen; No matter whether it is a positive bank, a water bank, a port bank or a water reform machine, it has its unique anti-counterfeiting characteristics without exception. Then, what are the internal and external characteristics of Samsung mobile phones, and what are the different personality characteristics of each model, and how can we identify them?

first, talk about the external features of Samsung mobile phone.

1, the fuselage. SAMSUNG's mobile phones are usually on the top of the inner and outer screens or at the rotating shaft, and at least one place is printed with the italic "Anycall" laser anti-counterfeiting logo, and the bottom of the outer screen is usually the bold "Samsung" laser anti-counterfeiting logo. However, the water reform machine usually only has the bold "SAMSUNG" laser anti-counterfeiting logo in the corresponding position, and there is no italic "Anycall" laser anti-counterfeiting logo.

of course, there are some special cases. For example, the italic "Anycall" laser anti-counterfeiting logo is printed on the outer screen of SAMSUNG S38 mobile phones, and the bold "Samsung" laser anti-counterfeiting logo is printed on the bottom of the screen. On the other hand, the top of the screen of the water reform machine is blank, and the bold "SAMSUNG" logo is printed on the bottom. Printed with the italic "Anycall" laser anti-counterfeiting logo is one of the external features that all Samsung mobile phones must have. However, it is still impossible to distinguish the mobile phones of the bank, the bank and the bank, because it is too easy for JS to replace a licensed case.

2. Navigation keypad. There is a concave direction arrow on the left and right direction keys of the circular navigation keys of Samsung's mobile phones, and there is an envelope symbol on the left key, which is a short message shortcut key, and a staff icon on the right key, which is a ringtone shortcut key. However, there are generally only four small arrows on the navigation key of water reform machine, or nothing at all.

There is a concave envelope sign and staff icon on the left and right direction keys of the navigation key, which is one of the external characteristics of Samsung's direct, parallel and Hong Kong mobile phones. In the past, we could identify Samsung's direct and parallel mobile phones by this point, but now it seems that it is not working, because the author found that Samsung's later navigation keys T4 and T5(T48 and T58 water-modified models) also have them on the left and right direction keys.

3. keyboard. There are Chinese strokes on the keyboards of Samsung's mobile phones, Shuixing's mobile phones and Hong Kong's mobile phones. The Chinese strokes

are coordinated with the English letters of the same key, and each Chinese stroke is directly above the middle letter, and the numbers, letters and strokes are all transparent. This is also one of the external characteristics of Samsung's mobile phones. Generally, there are no strokes on the keyboard of water reform machine, and the strokes of parallel mobile phones are usually added after JS. Because the English letters are centered in the design of the "water machine" keyboard, the Chinese strokes added after it must be * up, left or right, which feels forced and squeezed. The appearance color is darker than numbers and letters, and it is generally opaque. Now, except for English versions T4 and T5, most keyboards of water reform machines also have transparent strokes. Therefore, I would like to remind everyone to pay attention when buying. Try scraping the strokes on the keyboard with your nails. If it falls off, it proves that it is water instead of goods.

in addition, the keyboard of the new machine feels more resilient and elastic, while the second mobile phone feels softer when used, which is not as resilient as the new machine.

4. PCB board logo and mobile phone sticker. Generally, the models of Samsung's mobile phones are marked on the PCB in the SIM card slot, such as SGH—S38, SGH-S28, SGH-T18, SGH-X18, etc., while the European versions of SGH-3, SGH-S2, SGH-T1 and SGH-X1 are marked separately. There are also some Samsung mobile phones, such as T28, S18 and so on. Although the model of the mobile phone is not marked on the PCB circuit board, the model of the mobile phone will definitely be marked on the back of the mobile phone, behind the SSN or in front of the serial number S/N of the mobile phone.

Generally, there will be a white cotton sticker on the screw hole of the fuselage on the back of the licensed goods, which reads eight Chinese characters: "Maintenance sticker, tearing it up is invalid".

Of course, it is not enough to judge whether it is a mobile phone or not just by the back sticker, because JS has the means to replace this back sticker. I have witnessed a Samsung S1 mobile phone with S18 on the back.

Of course, there are differences between the back stickers on mobile phones of Hang, Shui and Hong Kong, and those posted after JS. After careful observation, it will be found that the IMEI number of the water reform machine is printed vaguely, while the printed goods are clearly visible.

5. IMEI code of mobile phone. IMEI (International Mobile Equipment Identity) is the abbreviation of international mobile equipment identification code, which is an "electronic serial number" composed of 15 digits, which corresponds to each mobile phone one by one, and the code is unique in the world. Every mobile phone will be given a unique group number in the world after assembly, and this number will be recorded by the manufacturers from production to delivery.

its composition is 123456-78-91234-5: the first 6 digits are "model approval number", which generally represents the model; 7 and 8 digits are "final assembly number", which generally represents the place of origin; The next 6 digits are "serial number", which generally represents the production sequence number; The last digit is usually "", which is a test code and is currently reserved. The IMEI code is attached to the sign on the back of the mobile phone and read and written in the memory of the mobile phone. It is also the "file" and "ID number" of the mobile phone in the manufacturer. Now Samsung's new models generally add two digits to the back of the inspection code. For example, the IMEI code is: 3515/89/59521/9…1.

To check the IMEI code of the mobile phone, you should first enter *#6#, check the IMEI code in the memory of the mobile phone, remember this number, then enter *2767*3855# to reset the chip, and the mobile phone will automatically restart. Finally, enter *#6# to see if this IMEI code has changed. If this number is consistent with the IMEI code on the back of the mobile phone and on the outer packaging box, and If it is inconsistent, or becomes a string of garbled codes, or the instructions are not executed, it is proved that the mobile phone is either a water reform machine or a refurbished machine. The latter chip reset function has been blocked by JS.

IMEI code is the main basis for mobile phone authentication. I really don't understand why many people don't pay enough attention to IMEI code now, so that they are deceived repeatedly. Someone once bought T28 with the "model approval number" of 52255 as a licensed product. If you have a certain understanding of the "model approval number" of T28, I believe such a thing will not happen.

6. network access license. Network access license belongs to the quality mark. Mobile phones that are not labeled with network access mark or labeled with fake network access mark shall not be sold in the market, nor are they allowed to access the telecommunication network.

there are two kinds of network access signs: one is the network access permission sign, and the other is the network access trial sign. Among them, the sign of network access permission is light blue, and the sign of network access trial is green.

the network access license sign consists of 12 digits, in the form of XX-XX-XXXX-XXXXXX, where the 3rd to 6th digits are the manufacturer's code, the original code of Samsung in Korea is 1628, and that of Samsung in Tianjin is 5827. From network access license, we can judge whether the origin of the mobile phone is Korean or Tianjin.

network access license is also one of the important bases for the identification of parallel mobile phones. Consumers can illuminate network access license with a banknote detector lamp. The real network access license is on the lower right of the sign, and you can see the red fluorescent letter CMII (the English abbreviation of the Ministry of Information Industry) and an unclear number. In addition, you can also see a fluorescent vertical line on it, which is obviously concave and convex when you touch it with your hands.

Except for the direct mobile phone, the mobile phones of Shuihang, Hong Kong Bank and Shuigai do not have network access license, and even if they do, they are fake-fake certificates printed by ordinary printers. Parallel mobile phones are slightly different from genuine network access signs: the real network access signs are generally printed by needle printers, the background pattern is light blue, the font is bold, the strokes are slightly thick, and the color is dark, so there will be no reflection when viewed from any angle, and the numbers are clear. Look carefully at the dents made by needles; Fake network access signs are generally printed by ordinary inkjet printers. The background pattern is dark blue, usually in Song style. The strokes are thin and reflective, and the numbers are not very clear, with burrs and no dents.

At present, network access license and IMEI code query are the most authoritative methods for mobile phone authentication. Inquire about the authenticity of mobile phones: you can visit the website of the Ministry of Information Industry () to inquire; Users of China Mobile and China Unicom can also send short messages for verification, that is, enter: RW# license number # scrambling code # mobile phone serial number in the mobile phone, and send it to 95 after input, and the telecommunication equipment network access authentication management information system will automatically reply the consumer authentication information; You can also call the Telecommunications Administration of the Ministry of Information Industry at 1-8258767 and 825313 for manual inquiry. Of course, you can also inquire through the free consultation telephone number of Samsung Technical Service Center. Don't worry, fake network access license and IMEI codes can't stand the query.

in addition, you should also pay attention to three obvious signs on the fuselage of licensed machines. One is a yellow round label with CCIB letters printed on it, which is a sign issued by China Commodity Inspection Bureau; One is the light blue network access license logo issued by the Ministry of Information Industry; The other is the "CCC---" sign. As long as one of the first two signs is missing, consumers can assume that the mobile phone is imported through an abnormal channel (the latter was only implemented in August this year).

The above is to identify the Samsung mobile phone and the water machine from the external characteristics of the mobile phone. Below, the author will talk about how to distinguish the mobile phone and the water machine from the internal characteristics such as the software and hardware versions and functions of the mobile phone.

1. Version information. Through the version information, we can know the old and new degree of the mobile phone. Because of the different launch time of licensed and parallel products, the versions of the mobile phone and the water machine are different. When querying the hardware and software version of the mobile phone, enter ""
