I want to buy a Samsung E908 recently. Please tell me how to distinguish between parallel imports and licensed products.

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 "TFT COLOR" 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 screen is printed with the words "Anycall", the words "AUTO FOLDER Color" are printed at the bottom of the screen, and the striking "SAMSUNG" laser anti-counterfeiting logo is printed at the bottom far from the screen. There is no sign above the outer screen of the water reform machine, only "automatic folder color" and the eye-catching "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. Before T400 and T500, the strokes of English version of mobile phones were usually added after JS. Because the keyboard design of the water improvement machine is English letters in the middle, the Chinese strokes added at the back must be * up, 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. General Samsung mobile phone models, such as SGH-S308, SGH-S208, SGH-T 108, SGH-T408, etc. , should be marked on the PCB in the SIM card slot, while 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. Generally, there will be a white cotton swab on the screw hole of the fuselage on the back of the licensed product, which reads eight Chinese characters: "Repair sticker, tearing it off 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. 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: 351005/89/0595219 ... 0/.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. 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 network access license consists of 12 digits, and the format is xx-XX-XX-XXXX-XXXXXX, in which the 3rd to 6th digits are the manufacturer code, and 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 uneven when you touch it with your hand. In addition to direct mobile phones, the mobile phones of Shuihang, Hong Kong Bank and Shuigai have no network access licenses, and even if they do, they are fake-fake documents 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. It should also be noted that licensed machines should see three obvious signs on the fuselage. 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 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. First, 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 authorization S308 is REV 1.0, and the software version is C 1, F 1, etc. After entering *#8888#, it will be displayed as follows: hwver rev1.0; ; After entering *#9999#, it will display: rev s1.6h-CHN s38zwcw1,where the penultimate letter in the second line represents the production date 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 B8 version as an example, the display is as follows: hwver rev1.5 rev s1.6h-CHN S38 zcwb8. In addition, you can also enter *#8999*8376263# or *#9998*8376263# to obtain more detailed mobile phone software and hardware version information and Take T400 as an example. After entering *#8999*8376263#, it will be displayed as follows: HW: mp 1.8000 (or1.8001.9000) SW: T48ZCWA8main: 9000. Second, internal functional differences. 2. 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, generally speaking, the menu settings of line and water machines 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 the author's level is limited, fallacies are inevitable, so I hope Samsung people will criticize and correct me. Limited by the conditions, the author can't give all the contents of the columns listed in the table, and some data need further research. I hope people of insight can join hands with * * * to finish the unfinished business of the author. From the battery: 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 battery is not the target 3.7v lithium ion polymer, but only 3.7V lithium ion; 5. The combination with the nose is not very tight, and there is a creaking sound when you press it with your hand. 7. The charging problem of S508 battery in the middle of S/N/which looks similar to the real thing: 1, use direct charging, and 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. After testing, it is found that the power consumption of 508 battery is about 0.0 1V per hour, the battery is fully charged at 4. 17V, and it will automatically shut down at 3.44V when there is no power, which means that theoretically the battery standby time will not exceed 73 hours. Frequently asked questions: 1, some machines cannot be charged due to software version, fake charger or fake battery, etc. The reason may be a software problem ... 3. If you scroll too fast, some computers will restart ... 4. Some computers occasionally turn off the alarm clock, and I have encountered it once. 5. Close the cover immediately after starting the machine, and it is common that the keyboard background light will not go out. 6. Use the *#8999*8378# command to check the battery information. Gprs Settings *2767*86927# Direct input! Can be set automatically! 1. Authentication: 1. The original seat is normally inserted and used, and the yellow light does not light up 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, use the original charger to charge: 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 >; Primary charger >; Ordinary seat charger >; Ordinary line charging. 4. Direct charging is high current charging, and the saturation after charging is worse than that of the seat that can be charged by trickle. The original factory seat can reach 4. 16V when fully charged for two hours, while the original factory direct charging voltage is mostly 4. 12V. 5. 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 with a 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. Questions about various data lines: S308, S208, V208, P 108, P408, D4 18, E608, S 108, C 108, etc. They are all PCB093LBE, and the data cables of these models are universal! The data lines of N628, T 108, T408, T508 and T208 are all PCB037DBE, and the data lines of these models are universal! S508, E708, X 108, E 108, X608 and other models of data cables. They are all PCB 133LBE, and the data cables of these models are universal! In addition: except for refitting the data cable, Samsung mobile phone version number description * (viewed through *#9999#). Example: S38ZWF 1 is split into S38ZWF 1, and the first part, the model part is English machine: s30 = s300s3m = s300mv20 = v200t10n62 = t100n62 = n620c/kloc. Year x = 2004w = 2003v = 2002u = 200 1 part iv, month a = month b = month c = month d = month part v, which month version a 1 = 1 day version a2 = On the back of the computer, the old motherboard has two COM ports! Most new motherboards are COM ports. It's easier to connect, but it's important to connect when you turn it off. Boot can only be connected to USB port! The computer will find out whether there is a data cable connected to the COM port during the self-check! Otherwise it will burn out the motherboard! Second, make sure that your BIOS and CMOS have opened the COM port channel! If you can't set up CMOS. Restart the machine, press the DEL key, and enter the BIOS settings. Ordinary CMOS will have two items starting with LOAD! Move the cursor to these two items, of course, you can't move to these two items at once! One by one, enter, y, enter, second, enter, y, enter. Then press F 10, y, and enter. The machine restarts automatically. At this point, your COM port must be opened! 3. When I arrive at the WINDOWS window and see my computer, right-click my computer. Select "Properties" and a window will pop up, as shown in the following figure. If your line is connected to COM 1, please double-click the communication port (COM 1). If your line is connected to COM2, please double-click the communication port (COM2). Select the baud rate, data bit, parity, stop bit and flow limit corresponding to your mobile phone! The pictures related to this question are as follows: Select the "Resources" tab to see if there are any conflicts. If yes, tick off the front of "Use Automatic Settings", double-click the "Interrupt Request" as shown below, and select the up and down arrows to the right of the point value until there is no conflict! Confirm all return! Fourth, according to the requirements of your mobile phone, open the software and choose the correct parameters, whether to connect or open the software first, that is your own business! It is better to restart before brushing, so as to avoid any system error when brushing, and restart again, not good! Note: The values used by the software must be the same as those set by the computer! XP Right-click my computer and select Hardware Configuration!
