Samsung D608) query; users of China Mobile and China Unicom can also send text messages for verification, that is, enter: RW#license number#scrambling code#mobile serial number in the mobile phone. After inputting, send to 9500, The telecommunications equipment network access certification management information system will automatically reply with consumer identification information; you can also call the inquiry hotline of the Telecommunications Administration Bureau of the Ministry of Information Industry: 010-82058767, 82050313 for manual inquiry. Of course, you can also inquire through the toll-free consultation hotline of Samsung Technical Service Center. Don’t worry, fake network access licenses and IMEI codes cannot withstand inquiries.
In addition, when purchasing, everyone should also pay attention to the fact that there are three obvious signs on the body of the licensed machine. One is a yellow round mark with the letters CCIB printed on it. This is the China Commodity Inspection Bureau. The signs issued by the Ministry of Information Industry; one is the light blue network access license sign 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 determine that the mobile phone was purchased through abnormal channels (the latter was only implemented in August this year).
The above is to identify Samsung phones and water machines based on the external characteristics of mobile phones. Next, the author will talk about how to distinguish Samsung phones and water machines from the internal characteristics of mobile phones such as software and hardware versions and functions.
1. Version information. The version information can tell how new or old the mobile phone is. Since the launch time of domestic products and parallel products is different, the versions of domestic and parallel products are also different. When querying the mobile phone hardware and software versions, enter "*#8888#" and "*#9999#" (or *#0837#) respectively to find out the relevant information of the mobile phone.
Take S308 as an example. The hardware versions of licensed S308 regular, water and Hong Kong products are all REV 1.0, and the software versions include C1, F1, etc. After entering *#8888#, the display is as follows: HWVER REV 1.0 ; After entering *#9999#, it will display:
REV S1.6h-CHN
S38ZCWC1
Among them, the penultimate letter in the second line indicates production Date, U represents 2001; V represents 2002; W represents 2003, and so on. The penultimate letter represents the software version number, with 12 letters such as A, B, C...L representing 12 months respectively. The above-mentioned C1 represents the first version in March.
There are many versions of water conversion machines, the hardware is generally 1.5, and the software versions include L1, B5, A6, B8, B8++, B9, A8, A9, etc. Taking the B8 version as an example, the display is as follows:
HWVER REV 1.5
REV S1.6h-CHN
S38ZCWB8
Except In addition, you can also enter *#8999*8376263# or *#9998*8376263# to learn more detailed software and hardware version information and MP value of the mobile phone. Taking T408 as an example, after entering *#8999*8376263#, the display will be as follows:
HW: MP 1.8000 (or 1.8001, 1.9000)
SW: T48ZCWA8
Main: 98C OGM: CCC
T400 is displayed as:
HW: MP 3.2001 (or 3.2002, 3.3000)
SW: T48ZCWA8
Main: 98C OGM: CCC
2. Intrinsic functional differences.
There are certain limitations in distinguishing mobile phones and mobile phones through software and hardware versions, especially when mobile phones and mobile phones have the same version number but are actually two completely different versions. As mentioned before, T408 and T400 both have A8 versions, but they are actually two different versions. Therefore, in the process of mobile phone identification, it is particularly important to test the internal call quality and functions of the mobile phone.
The general principle is to use the licensed model of the purchased model as a reference standard, learn about the model’s version and various functions in detail from the manufacturer and dealer, and test them one by one during the purchase process. One of the most effective methods for branches and water machines.
Take T408 and T400 as an example. The licensed A8 version of T408 has phone message and language dialing functions. The calculator function can be used in Chinese mode, and the key tones have the voices of girls and ladies. The A8 version of T400 does not have the above functions.
Generally speaking, the licensed version is better than the modified version in terms of stability and language compatibility. The early modified version has more bugs. With continuous improvement, these bugs are gradually solved. . This is the main reason why there are more water-modified versions than mobile versions.
In addition to different internal functions, in general, the menu settings of row and water machines are also slightly different, so please pay attention.
Finally, you need to plug in the SIM card to test the call quality and signal strength of the mobile phone. Whether it is a commercial or parallel product, the voice of a genuine phone should be clear during calls, without noise or current, and the volume should be loud enough. , plug in the headphones and it can be used normally. Cover the antenna with your hand and the signal reduction should not exceed two bars at most. Otherwise, it means there is something wrong with the quality of the phone.
Some people are worried about buying a refurbished phone, so how to check whether the phone they purchased is a refurbished phone?
1. Shell. The shell of the new machine is tightly joined, and the gaps are flat and smooth without burrs. Refurbished machines generally use imitation of the original casing. The gaps are uneven and have burrs. The upper and lower parts of the mobile phone casing are prone to not closing tightly, leaving large gaps. When identifying, you can use your little fingernail to try to insert it into the seam between the upper and lower covers of the mobile phone. If it can be plugged in, it's a refurbished machine. And you should never buy a mobile phone with a matte surface like a new phone and small particles on it. The paint on the casing of this kind of machine is sprayed by JS. Over time, the paint will fall off (the small dust particles on the casing are caused by the lack of vacuum environment when painting);
2. New There is a faint smell of sandalwood when you open the cover of the machine. If it is a refurbished machine, JS usually needs to do some cosmetic work on the body. Although the surface is smooth, it is not dry enough. There is a rubbery, plastic, or chemical smell after opening the cover or removing the battery. The smell of chemicals;
3. Keyboard and data cable interfaces. Due to long-term plugging and unplugging of charger plugs and data cables, black scratches will appear on the charging interface of refurbished machines that are difficult to remove. Most keyboard refurbished machines use the keyboard from the old machine or imitate the keyboard. The uniqueness of this keyboard is that it feels soft and does not have the toughness of the new keyboard;
4. Charging test. It is best to charge for a longer time, usually more than 10 minutes. Because many refurbished machines will lose power after charging for a long time. This is also a very effective way to judge refurbished machines;
5. SIM card chip contacts and battery contacts. These two contact JS generally cannot be replaced. If it is a refurbished machine, there will definitely be clear friction marks on the SIM card chip contacts, which will look shiny. This is caused by excessive friction. If it is an unused chip from a new machine, the contact surface should be frosted;
6. Fixing screws. Mainly check whether there are obvious scratches on the screws and the knife-edge interface, and whether there are pick marks on the two rubber pads under the inner screen.
7. Call quality. Bring your own SIM card to test the machine, call your friend, preferably a landline, and ask the other party how the call quality is, whether the call sound is clear, whether there is any noise, current sound, and whether the volume suddenly drops;
8. Price. Since most of the spare parts for refurbished machines are early products and of poor quality, the price is also low. If you encounter a mobile phone with a ridiculously low price but the merchant calls it a parallel import, you can basically conclude that it is a refurbished phone.
To sum up, this article focuses on the internal and external characteristics of rows and water machines, and introduces the identification methods of rows and water machines. In the next article, the author will try to identify mobile phones and water dispensers from mobile phone accessories, as well as the experience in purchasing accessories. Due to the limited level of the author, fallacies are inevitable, and I hope the Samsung family will criticize and correct me.
Attachment: List of Samsung mobile phone network access licenses and equipment approval numbers (1 and 2). Due to conditions, the author cannot give all the contents of the columns listed in the table, and individual data needs to be further verified. .
I hope that people with insight can work together to complete the work that the author has not completed.
1. The fake battery does not have a mold number, that is, 1-1, 1-2, etc.; 2. The workmanship is not sophisticated enough. Especially the edges are not smooth enough and have a burr-like phenomenon;
3. The color is slightly darker than the real board;
4. The battery is not the standard 3.7v li-ion ploymer, only 3.7v li-ion;
6. The connection with the machine head is not very tight, and there is a creaking sound when pressed by hand.
7. The / in the middle of S/N seems to be too It’s similar to the real thing (JS is so fast to learn).
Solve the charging problem of S508 battery:
1. Use direct charging, just find an original Samsung direct charging instead;
2. Use original charging The dock charger can be modified with a T408 dock charger, but it needs to be connected to a direct charger;
3. It is best to use a T408 dock charger such as Scud instead. Plug in the dock charger first and push the battery into the card slot. , usually there will be a red light (power) and a green light (saturation). Don’t worry, move the battery so that it shows two red lights (power and charging). No need to tie it with rubber bands at all.
I found after testing
The 508 battery consumes approximately 0.01V per hour.
The battery is 4.17V when fully charged and 3.44V when it automatically shuts down when empty.
This means that theoretically the battery standby time will not exceed 73 hours.
1. Some machines may not be able to charge. The reasons include software version, fake charger or fake charger. Battery, etc...
2. Some machines will restart when entering voice dialing. The reason may be software problems...
3. Some machines will restart if they scroll too fast. ..
4. The alarm clock will occasionally not sound when some machines are turned off. I encountered this once.
5. It is relatively common to close the cover immediately after turning on the machine and the keyboard background light does not go out.
6. Use the *#8999*8378# command to check the battery information.
Gprs setting *2767*86927# type directly! It will be set automatically!
1. Regarding the identification of authenticity:
1. Insert the original The charger is in normal use, and the yellow light does not light up when charging;
2. The screws of the charger are hexagon sockets. After being disassembled, the circuit board is green and the components are arranged neatly; the connection between the circuit board and the power plug is It is connected with a clip, not welded;
3. Open the plug on the mobile phone and there is a small refined circuit board connected to the wire.
4. Direct charging of J, S, V, and P series is universal;
5. Samsung’s customer service charge is 150 yuan, which is too much.
2. Several suggestions:
1. Use the original charger to charge: The original charger helps to improve the charging quality and protect the battery;
2. If you have both the original line charger and the cradle charger, it is recommended to use the cradle charger for charging, because the trickle charging of the cradle charger can ensure full battery power;
3. After charging, remove the battery and use *# 8999*8378# Check the battery status. The normal voltage is between 4.1V and 4.2V (usually the original cradle charger can charge to 4.2V or near it, and the line charger is worse). If it is higher than 4.2V, it is overcharged. If it is lower than 4.1V, it is normal. Because I am not full.
The charging effect of the charger: original stand charger>original line charger>ordinary stand charger>ordinary line charger.
4. Direct charging is a high-current charging. The saturation after charging is worse than that of a stand charger that can trickle charge. The voltage of the stand charger can reach 4.16V after two hours of full charge. The voltage after the original direct charger is fully charged is mostly 4.12V
5 If you use direct charger, charging will usually stop after 2 to 3 hours, and the voltage will drop slowly. If you unplug the direct charger If you plug it in again, you will find that the battery is charging again, which is normal
Use a cradle charger. After 3 to 4 hours of full charging, it will switch to a low current maintenance process, and the battery power will not drop too much. More, 4.09V is a little lower, but it shouldn’t be a big problem
As long as the battery’s standby time is normal, you don’t need to care too much, and you don’t need to care too much about the displayed power.
