Anycall is in front, only banks in mainland China, Hong Kong and Taiwan are allowed.

Oushuidu is a Samsung.

The version numbers of Mainland Bank and Hong Kong Bank are D838Zfk 1 or L 1.

The version of Oushui is D830DXF__.

Nowadays, in the mobile phone market with dazzling 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.

Then, in the parallel market of Samsung, how to distinguish the right line, waterline and water reform machine? How to distinguish original accessories from counterfeit accessories? This is the main idea of this article. For a time, the author was lucky enough to "talk" with many Samsung fans through the Friends Business Forum, which benefited a lot. The superficial experience is that most people know little about Samsung's so-called common sense of straight line, waterline and water reform machine, and even have 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, waterline and water reform machine.

There have been different views on the classification of Samsung mobile phones. Judging from whether the products are in normal entry inspection, Samsung mobile phones should be divided into four categories:

I. Authentic licensed products (Line A) The so-called genuine products refer to the mobile phones produced in Korea or Tianjin, which have passed the normal entry inspection and the certification of the Ministry of Information Industry, and have the network access license and the national warranty certificate, 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 assurance. Parallel imports can be divided into two types. One is parallel imports (line B), which are strictly permitted. However, due to smuggling to the mainland, there is no network access card. However, due to the manufacturer's nationwide warranty, this kind of mobile phone can also be guaranteed. The other is the Bank of Hong Kong, 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 card, Hong Kong banks can't get warranty protection in the Mainland; The third is the water reform machine. This kind of mobile phone is usually called genuine parallel imports. This kind of mobile phone was originally sold to Europe and America and smuggled to the mainland. JS turned its English software into Chinese software (plus Chinese fonts), making it a mobile phone that supports Chinese. Because Chinese fonts occupy a part of the memory used for other functions, the mobile phone may "sacrifice" some of its original functions. Besides, there may be some bugs 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 mobile phone a revision machine, which is really inappropriate. From a dialectical point of view, the so-called modification should be divided into soft and hard. Water reform machine is a mobile phone that changes the original software without making any changes to the hardware. If you change the hardware, it should belong to the trigger in the second mobile phone mentioned later in this article.

The third type is the assembly machine, most of which is 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 a parallel import in the strict sense from the assembly site and sales channels, and 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 mobile phone and trigger. Renovation is to change the shell, clean up the appearance, and sell the second-hand mobile phone as a new machine. The trigger is to upgrade a certain part of the mobile phone to a high-end model through hardware transformation such as replacing parts, such as converting Siemens 35 18 to 3568. And the quality is not guaranteed at all. As mentioned above, many consumers who want to buy parallel imports but are afraid to buy them are afraid of meeting assembly machines and second-hand mobile phones, especially the latter.

So, how to distinguish right line, waterline and water reform machine?

In fact, as long as we pay a little attention, we will find that whether it is a Samsung straight 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 Hong Kong bank or a water reform machine, it has its unique anti-counterfeiting features without exception. Then, what are the internal and external characteristics of Samsung mobile phones, what are the different personality characteristics of each model, and how can we identify them?

First of all, try to talk about the external characteristics of Samsung mobile phones.

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

Of course, there are some special circumstances. For example, the external screen of SAMSUNG S308 mobile phone is printed with an italic "Anycall" laser anti-counterfeiting logo, and the bottom of the screen is printed with a bold "Samsung" laser anti-counterfeiting logo. On the other hand, the top of the screen of the water reform machine is blank, and the striking "Samsung" logo is printed on the bottom. Samsung T408 mobile phone is printed with italic "Anycall" laser anti-counterfeiting logo on the top of the outer screen and the rotating shaft, and "TFTCOLOR" logo is also printed on the bottom far away from the outer screen. Although the water reform machine also has this logo, a careful observation shows that the orange "F" in the middle of the licensed product is thinner and more delicate than the strokes of the water reform machine. For another example, T208' s mobile phone has the words "Anycall" printed on its outer screen, "AUTOFOLDERColor" printed on the bottom of the screen, and the striking "SAMSUNG" laser anti-counterfeiting logo printed on the bottom far from the screen. However, there is no sign above the outer screen of the water reform machine, only the "AUTOFOLDERColor" and the bold "SAMSUNG" sign below.

The italic "Anycall" laser anti-counterfeiting logo printed on the top of the internal and external screens or on the rotating shaft is one of the external features that all Samsung mobile phones must have. However, on this basis, it is still impossible to identify the mobile phones of the main line, parallel line and Hong Kong line, because it is too easy for JS to replace a licensed shell.

2. Navigation keyboard. There is a concave direction arrow on the left and right direction keys of the oval navigation key of Samsung mobile phone, 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 usually only four small arrows or nothing on the navigation key of water reform machine.

There is a concave envelope mark and a staff icon on the left and right direction keys of the navigation key, which is one of the external features of Samsung's mobile phone. In the past, we can use this to identify Samsung's mobile phone and water machine, but now it seems to be no good, because the author found that there are also concave envelope marks on the left and right direction keys of Samsung's new T400 and T508 navigation keys.

3. Keyboard. There are Chinese strokes on the keyboards of Samsung's direct, parallel and Hong Kong mobile phones. Chinese strokes are in harmony with the English letters of the same key. Each Chinese character stroke is directly above the middle letter, and the numbers, letters and strokes are transparent. This is also one of the external characteristics of Samsung mobile phones. There are no strokes on the keyboard of the general water reform machine. The strokes of English mobile phones before T400 and T500 are usually added after JS. Because the keyboard of the water reform machine is designed with English letters in the middle, the Chinese strokes added at the back must be on K, left or right, which feels very hard and crowded. Appearance color is darker than numbers and letters, and it is generally opaque. Now, except for English versions T400 and T500, most keyboards of water reform machines are also transparent strokes. So I would like to remind everyone to pay attention when buying. Try scraping the strokes on the keyboard with your nails. If it is dropped, it proves that it is water and not goods.

In addition, the keyboard of the new machine feels more resilient and elastic, while the second mobile phone feels softer and has no toughness of the new machine.

4, PCB circuit board logo and mobile phone back post. Generally, the models of Samsung mobile phones are marked on the PCB in the SIM card slot, such as SGH—S308, SGH—S208, SGH-T108, SGH—T408, etc. And the European versions of SGH-300, SGH-S200 and SGH-T65438. There are also some Samsung mobile phones, such as T208, S 108 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.

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

Of course, it is not enough to judge whether it is a mobile phone only by the back sticker, because JS has a way to replace this back sticker. The author once witnessed a Samsung S 100 mobile phone with the label S 108 on the back.

Of course, there is still a difference between the back stickers on mobile phones in Hangzhou, Shanghai and Hong Kong and those posted after JS. If you look closely, you will find that the IMEI number of the water reform machine is printed very vaguely, but the printed goods are clearly visible.

(Recommended) 5, mobile phone IMEI code. IMEI (International Mobile Equipment Identification Code) is the abbreviation of international mobile equipment identification code, which is an "electronic serial number" composed of 15 digits, corresponding 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 manufacturer from production to factory.

Its composition is123456-78-901234-5: the first six digits are "model approval number", which generally represents the model; 7, 8 digits for the "assembly number", generally representing the place of origin; The next six digits are "serial number", which generally represents the production sequence number; The last bit of 1 is usually "0", which is a check code and has been reserved at present. The IMEI code is attached to the sign on the back of the mobile phone and read and write in the memory of the mobile phone. It is also the "document" and "ID number" of the mobile phone in the manufacturer. Now Samsung's new models usually add two digits after the inspection code. For example, the IMEI code is: 351005/89/059521/9 ... 01.

To check the IMEI code of a mobile phone, first enter *#06# to check the IMEI code in the memory of the mobile phone, remember this number, and then enter *2767*3855# to reset the chip, and the mobile phone will automatically restart. Finally, enter *#06# to check whether this IMEI code has changed. If this number is consistent with the IMEI code on the back of the mobile phone and the outer packaging box, and the model approval number is consistent with the model of the mobile phone. If it is inconsistent, or becomes a string of garbled codes, or the instructions are not executed, it proves that the mobile phone is either a water-changing machine or a refurbished machine. The back 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 T208 with the model approval number of 520255 as a licensed product. If you know something about T208' s "Model Approval Number", I believe this will not happen.

6. Network access license. Network access license is a quality symbol. Mobile phones that are not marked with network access signs or marked with false network access signs shall not be sold in the market, nor shall they be connected to telecommunication networks.

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 network access permission sign is light blue, and the network access trial sign is green.

The sign of the network access license consists of 12 digits, and the format is xx-XX-XX-XXXX-XXXXXX, where the 3rd to 6th digits are the manufacturer code, the original code of South Korea Samsung is 1628, and the original code of Tianjin Samsung is 5827. From the network access license, it can be judged whether the origin of the mobile phone is Korea or Tianjin.

Network access license is also an important basis for identifying parallel imports and parallel mobile phones. Consumers can use the money detector lamp to illuminate the network access license. 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 see that there is a fluorescent vertical line on it, which is obviously concave and convex when you touch it with your hand.

Except for the mobile phones of Bank of China, the mobile phones of Shuihang, Hong Kong Bank and Shuigai have no network access licenses, 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 pin printers, with light blue background patterns, bold fonts, slightly thicker strokes and darker colors, so no matter from which angle, there will be no reflection and the numbers will be clear. Look carefully at the dent made by the needle; False network access signs are generally printed by ordinary inkjet printers. The background pattern is dark blue, usually in Song Dynasty. The strokes are thin and reflective, the numbers are not very clear, there are burrs and no dents.

At present, the most authoritative methods for mobile phone authentication are network access license and IMEI code query. Check the authenticity of the mobile phone: you can visit the website of the Ministry of Information Industry (); 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 then send it to 9500, 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 0 10-82058767 and 820503 13 for manual inquiry. Of course, you can also inquire through the free consultation telephone number of Samsung Technical Service Center. Don't worry, the fake network access license and IMEI code can't stand the query.

In addition, it should be noted that the licensed machine should see three obvious signs on the fuselage. One is a yellow circular label printed with CCIB letters, 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 mobile phones are imported through abnormal channels (the latter was only implemented in August this year).

The above is the identification of Samsung line and water machine from the external characteristics of mobile phones. Below, the author talks about how to distinguish the line water machine from the internal characteristics such as the software and hardware version and function of the mobile phone.

(Recommended) 1. Version information. Through the version information, you can know the old and new degree of the mobile phone. Because the time to market of licensed products and parallel products is different, the versions of mobile phones and water machines are also different. When inquiring about the software and hardware version of the mobile phone, enter "*#8888#" and "*#9999#" (or *#0837#) respectively to find the relevant information of the mobile phone.

Take S308 as an example. The hardware version of the licensed S308 is REV 1.0, and the software version is C 1, F 1, etc. After entering *#8888#, it will be displayed as follows: hwverrev1.0; ; After entering *#9999#, it will be displayed:

Version 1.6 hours-China

s38zwcw 1

Among them, the penultimate letter in the second line represents the date of production, and u represents 200 1 year; V stands for 2002; W stands for 2003, and so on. The last letter represents the software version number, and the letters A, B, C…L, etc. 12 respectively represent 12 months, and the above-mentioned C 1 represents the first version in March.

However, there are many versions of water modification machines, the hardware is generally 1.5, and the software versions are L 1, B5, A6, B8, B8++, B9, A8, A9 and so on. Take the B8 version as an example, as shown below:

HWVERREV 1.5

Version 1.6 hours-China

S38ZCWB8

In addition, you can also enter *#8999*8376263# or *#9998*8376263# for more detailed software and hardware version information and MP value of the mobile phone. Taking T408 as an example, after entering *#8999*8376263#, the following is displayed:

Hardware: hardware: MP 1.8000 (or 1.800 1, 1.9000).

Software: T48ZCWA8

Main: 98COGM:CCC

T400 is displayed as:

Hardware: MP 3.200 1 (or 3.2002, 3.3000)

Software: T48ZCWA8

Main: 98COGM:CCC

Second, internal functional differences.

There are still some limitations in distinguishing line from water by software and hardware versions, especially for line and mobile phones with the same version number, which are actually two completely different versions. As mentioned above, both T408 and T400 have A8 versions, but they are actually two different versions. Therefore, in the process of mobile phone authentication, it is particularly important to test the internal call quality and function of the mobile phone.

The general principle is that it is one of the most effective ways to distinguish the company from the water pump by taking the licensed products of the purchased models as the reference standard, knowing the versions and functions of the models from the manufacturers and distributors in detail, and testing them one by one during the purchase process. Take T408 and T400 as examples. T408 is a licensed A8 version, which has the functions of telephone message and language dialing. The calculator function can be in Chinese, and the key sounds are more the voices of girls and ladies. A8 T400 does not have the above functions.

Generally speaking, the licensed version is better than the water revision in stability and language compatibility, and there are more bugs in the early water revision. With continuous improvement, these bugs are gradually solved. This is also the main reason why the number of versions of water reform machines is more than that of wire machines.

In addition to the different internal functions, in general, the menu settings of the line and the water machine are slightly different, please note.

Finally, try the call quality and signal strength of the mobile phone on the card. No matter whether it is parallel imports or parallel imports, the sound of genuine mobile phones should be clear, without noise or current sound, and the volume should be large enough to plug in headphones for normal use. Cover the antenna with your hand, and the signal attenuation shall not exceed two squares at most. Otherwise, there is something wrong with the quality of the mobile phone.

Some people are worried about buying a refurbished machine, so how to check whether the purchased mobile phone is a refurbished machine?

1, shell The shell of the new machine is tightly attached, and the gap is smooth and smooth without burr. Refurbishers generally use imitation original shell, with uneven gaps and burrs. The upper and lower parts of the mobile phone shell are easy to be closed loosely, leaving a large gap. When recognizing, you can try to insert a small nail into the gap between the upper and lower covers of the mobile phone. If it can be plugged in, it is a refurbished machine. The surface of the shell is frosted like a new machine, and the mobile phone with small particles is absolutely not to be purchased. The paint on the machine shell was sprayed by JS. After a long time, the paint will fall off (the dust particles on the shell are caused by the operation without vacuum environment when painting);

2. The shell of the new machine has a faint sandalwood smell. If it is a refurbished machine, JS generally needs to beautify the fuselage. Although the appearance is smooth, it is not dry enough. After opening the lid or taking out the battery, it smells like rubber, plastic or chemical;

3. Keyboard and data cable interface. Due to the long-term plugging and unplugging of the charger plug and data cable, there will be black scratches on the charging interface of the refurbished machine that are difficult to eliminate. Keyboard refurbished machines mostly use the keyboard on the old machine or imitate the keyboard. The * * * of this keyboard is that it feels soft and has no toughness of the new keyboard;

4. Charging test. It is best to charge for a long time, generally 10 minutes or more. Because there are many refurbished machines that will run out of power after a long charging time. This is also a very effective method to judge the refurbished machine;

5.SIM card chip contact and battery contact. Generally, these two contacts JS cannot be replaced. If it is a refurbished machine, there will be obvious friction marks on the contacts of the SIM card chip, which looks shiny, which is caused by too much friction. If it is an unused chip of a new machine, the contact surface should be frosted;

6. Fix the screws. Mainly depends on whether there are obvious scratches at the interface between the screw and the blade, and whether there are pick marks on the two rubber pads below the inner screen.

7. Call quality. Bring your own SIM card to test the machine, call a friend, preferably a fixed phone, and ask the other party how the call quality is, whether the call sound is clear, whether there is noise, current sound and volume drop suddenly;

8. price. Because the spare parts of refurbished machines are mostly early products with poor quality, the price is also low. If you encounter a mobile phone that is ridiculously low in price but is called parallel imports by merchants, you can basically conclude that it is a refurbished machine.

To sum up, this paper focuses on the internal and external characteristics of walking machine and water machine, and introduces the identification method of walking machine and water machine. In the next part, the author will try to distinguish the experience of buying and selling mobile phone accessories. Because of the author's limited level, fallacies are inevitable and still hope.

Three stars criticize and correct me.

Attachment: List of Samsung mobile phone network access license and equipment approval number (I and II). Due to the limitation of conditions, the author can't give all the contents of the columns listed in the table, and some data need further textual research. I hope people of insight will work together to finish the work that the author has not finished.

1. The fake battery has no module number, just the words 1- 1, 1-2; 2. The workmanship is not excellent enough, especially the edges are not lubricated enough, and there are similar burrs;

3. The color is slightly darker than the real disk;

4. The target of the battery is not 3.7 VLI ions, but only 3.7 VLI ions;

6. The combination with the nose is not very tight, and there is a creaking sound when you press it with your hand.

7. The one in the middle of S/N also looks similar to the real thing (JS learns really fast).

Solve the charging problem of S508 battery:

1, with direct charging, just find a Samsung original direct charging instead;

2. The original seat charger can be modified with T408 seat charger, but it needs to be connected with direct charging;

3. It is better to replace it with T408 seat charger such as Scud. First insert the seat charger and push the battery into the card slot. There is usually a red light (power supply) and a green light (saturation). Don't worry, the mobile battery shows two red lights (power supply and charging), and there is no need to tie it with a rubber band at all.

I found through the test that

508 battery consumes about 0.0 1V per hour.

The fully charged battery is 4. 17V, and the automatic shutdown without power is 3.44V.

In other words, in theory, the battery standby time will not exceed 73 hours.

1, some machines can't be charged because of software version, fake charger or fake battery, etc. ...

2. Restarting an individual phone when it enters voice dialing may be a software problem. ...

3. If the scroll is too fast, individual machines will restart. ...

Occasionally, the alarm clock of individual machines won't ring. I met once.

5. Close the cover immediately after starting, and the keyboard background light will not go out, which is more common.

6. Check the battery information according to * # 8999 * # 8378.

Gprs Settings *2767*86927# Direct input! Can be set automatically!

A, about the identification of straight true and false:

1, the original charger is used normally, and the yellow light does not light when charging;

2. The screw of the charger is hexagonal. After disassembly, the circuit board is green and the components are arranged neatly; The connection between the circuit board and the power plug is connected by clips, not by welding;

3. Disconnect the plug of the mobile phone, and a small refined circuit board is connected to the wire.

4.J, S, V and P series direct charging universal;

5, Samsung customer service asking price 150 yuan, too J ..

Second, some suggestions:

1, charging with the original charger: the original charger helps to improve the charging quality and protect the battery;

2. If the original line charger and the seat charger are available at the same time, it is recommended to use the seat charger for charging, because the trickle charging of the seat charger can ensure full and sufficient battery power;

3. After charging, take out the battery and use *#8999*8378# to check the battery status. The normal voltage is between 4. 1V and 4.2V (usually, the original seat can be charged to 4.2V or nearby, and the line charging is almost the same). Above 4.2v is overcharged, and below 4. 1v is usually not fully charged.

Charging effect of charger: original seat charging > original line charging > ordinary seat charging > ordinary line charging.

4. Direct charging is high current charging, and the saturation after charging is worse than that of trickle charging seat. The voltage of the original seat can reach 4. 16V after being fully charged for two hours, while the voltage of the original seat after direct charging is mostly 4. 12V.

If you use direct charging, stop charging after 2 ~ 3 hours, and the voltage will drop slowly. If you unplug the direct charge and plug it in, you will find that the battery is charging, which is normal.

After charging the seat for 3 ~ 4 hours, it will switch to the low current maintenance process, and the battery power will not drop too much. The 4.09V is a little low, but it should not be a big problem.

As long as the battery standby time is normal, you don't have to care too much, and you don't have to care too much about the displayed power.
