2. Generic machine: the so-called licensed machine, which enjoys three guarantees in customer service.
3. Hong Kong banks are licensed in Hong Kong. Since NOKIA now carries out joint warranty in Greater China, machines of Hong Kong banks can enjoy joint warranty in mainland China only with valid purchase certificates.
4. Parallel imports: 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.
5. Water reform machine: This kind of mobile phone is usually called authentic parallel. This kind of mobile phone was originally sold in Europe and America, and smuggled into the mainland. By translating its English software into Chinese software (adding Chinese font), it became a mobile phone sales supporting Chinese.
6. Original parallel imports: generally from European countries, usually English machines, upgraded to Simplified Chinese through software.
7. Refurbisher: It refers to selling a second mobile phone with its casing replaced as a brand-new machine, which is of poor quality. In fact, it is to collect the original movement, casing or outer packaging for maintenance or processing, and then sell it as a new machine. There are many kinds of them, mainly, the old machines with a circuit board problem are repackaged and sold after maintenance or parts assembly, and the performance of such machines is the most unstable; Second, the shell of the normal old machine is sold as a new one after being treated or replaced; Thirdly, informal channel machines are sold as new ones after being refreshed and repackaged by software, and the stability of general software of such machines is lacking.
8. charging machine: the mobile phone with nearly brand-new color is sold as a brand-new machine after being processed.
9. trigger: a machine assembled with accessories in pieces, with a general service life of less than one month.
The above-mentioned machine softwares, such as XinJi, Hong Kong Bank and Pure Water, are all good, and there are no bugs. From the appearance, the licensed He Hong Bank has Chinese strokes on the keys of the machine, while the European version does not. From the startup point of view, the licensed products are simplified Chinese, and the Hong Kong version is traditional Chinese. Needless to say, the European version must be written in English or other countries. What needs attention is renovation, charging new machines and triggering machines.
Let me talk about the identification of refurbished machines:
1. First of all, we must get out of a misunderstanding. The most common thing people look at when buying machines is *#6# to distinguish the place of origin. The seventh and eighth codes of serial numbers indicate the place of origin of mobile phones. The code of Nokia is as follows:
1: Finland;
2: Germany;
3: Korea;
4: Beijing;
6: Dongguan,
But the new nokia mobile phone no longer uses this number to distinguish the place of origin. When the mobile phone is in standby mode, enter # 6 #, and a string of numbers displayed by the mobile phone is its motherboard serial number, so write it down; Take off the battery of the machine, and look at the serial number on the white label in the two labels behind the machine body, that is, the serial number of the casing, and the other label is generally the network access license. Whether it is consistent with the previous figures; Look at the IMEI number on the box of the machine again and compare the three to see if they are all consistent. If the serial number of the motherboard and the serial number of the chassis are inconsistent, then this machine is likely to be repaired or assembled, and you must never buy it. If the three serial numbers are the same, plus the network access license, it can basically prove that the machine is genuine, but it can't be 1% sure, because JS can fake anything now, the serial number of the motherboard can be written by computer and software, and the fake serial number label and network access license can be bought for a few dollars. For the sake of prudence, we should continue to verify it in the following ways.
2. Many people who have used Nokia machines will also know a command, that is, standby input *#9272689#, but this command is that Nokia s4 machines can enter the engineering mode of the machine ~ where Life Timer stands for the total talk time of the machine ~ and Repaired stands for maintenance information, etc. ~ but this command is invalid in Nokia s6 machines.
3. Carefully check whether there are any poking marks at the battery lock of the fuselage, whether the sim card slot and contacts are worn, and whether the contact points of the MMC card are imprinted. It should be brand-new and bright.
4. Look at the packaging and instructions of the machine: the packaging and instructions of the regular new machine are beautifully printed, mostly on coated paper, with clear fonts and images, and a sense of hierarchy, while the counterfeit packaging boxes are mostly made of simple one-sided paper, with rough fonts and images, blurred printing, and many instructions for modification in informal channels are even copied. There are also some refurbished machines that use the original genuine packaging boxes and instructions, but after all, the machines are old, the packaging boxes must be worn, and the instructions must have traces of use. You can find them if you pay more attention when buying.
5. Look at the network access license: there is a watermark on the network access license, and the color of the surface is uneven, with deep and light, thick and thin; The fake ones are mostly copies, and the surface color has not changed. If you can't see it, you can also use the money detector to take a look at the network access permit. Is there really an anti-counterfeiting pattern in it? Will present a red "CMII" pattern. The fake pattern is blurred. Real network access permits are usually printed by pin printers, and the numbers are clear. Look carefully at the dents made by pins, while fake network access permits are printed by ordinary printers, and the numbers are not very clear and there are no dents. Generally speaking, it is difficult to fake the network access license, after all, the equipment required for fraud is relatively high in cost. In addition, you can also check the authenticity of the network access license by online inquiry, which will not be explained in detail here.
6. Look at the case of the mobile phone: When you open a new phone, you will obviously notice that the "key parts" of the phone are covered with film for key protection, such as the inner screen, the outer screen, the camera head, etc. As long as these parts touch, they will leave fingerprints. When you see the fingerprints on the new phone, don't listen to JS's explanation. In addition, dust and traces of use are also unavoidable when renovating the machine. The gap between the upper and lower shells of the machine (generally about 1MM), the gap around the keyboard, and the charger slot are all places that are easy to "shelter evil people and shelter evil people", and the rotating shaft of the flip machine will also leave traces of use, so special attention should also be paid to it. Generally, the shell used in the refurbished machine is original, or the old shell is carefully processed, so the front and rear parts of the machine shell are easy to be closed loosely and have a large gap. The identification method is to try whether it can be inserted into the seam of the upper and lower covers of the mobile phone with fingernails. If it can be inserted, it is an assembled shell. For the machine that has not replaced the shell, JS uses a mist like detergent before selling, and the surface of the old shell immediately appears a frosting effect like that of the new machine. If you don't look carefully, JS will muddle through, but it won't take long for the paint of the shell to fall off. When buying, you must carefully observe the shell, because JS's technology is no matter how good, and it is not as advanced as the original equipment. If you look carefully, you can see a little particle. It's dust, which is caused by not working in a vacuum room when painting. If it is a clamshell machine, you can also check the joint of the clamshell, because sometimes, even if JS handles the surface of the machine well, these places will inevitably leave some traces of dust. In addition, check whether the screws of the fuselage are brand-new and whether there are any traces of screwdriver twisting. More importantly, many new mobile phones have an obvious smell of sandalwood, while the old phones and shell changers generally don't have such a smell, or have an odor left during processing, while the new machines will have a smell of sandalwood, which is different from the general detergent and perfume. The body can't have sticky wax and oil (if there is, it is beautified by JS).
7. Look at the screen sticker: the brand-new one should be pasted well, with no air bubbles or anything, and it is seamless.
8. Look at mobile phone accessories: The new machine of a regular manufacturer has a full set of original accessories, and at least it must be charged once. The accessories of refurbished mobile phones are generally incomplete or not original. Before purchasing, it is best to go to the relevant website to find out what the original accessories are as standard, so as to prevent JS from deducting accessories. In addition, there are scratches on the plug of the matching charger and earphone. Generally, the old machine must have been charged, but you can still see the difference. See if the earphone of the mobile phone is black. If it is, it may be refurbished or used.
9. Look at the records: Look at the records of games, short messages, phone books, call records, self-made ringtones, WAP and voice functions, call records and other items in the mobile phone. If so, there is a great suspicion of renovation. In addition, in the normal use process, the machine frequently shuts down or crashes automatically, so it can be said for sure that there is something wrong with the motherboard or software of this mobile phone.
1. Look at the warranty: ask the dealer about the warranty period of the machine and ask for a formal invoice. Refurbished mobile phones cannot enjoy all the rights and interests stipulated in the "three guarantees" of regular mobile phones, so there is generally no warranty period or a relatively short warranty period. If the seller says that they are responsible for the warranty, they can't agree, because regular mobile phones are generally guaranteed nationwide. If the seller can't do this, then there must be something wrong with the mobile phone.
11. Look at the price: Before buying a mobile phone, it is best to find out the price of the mobile phone in the local newspaper or website. If the price quoted is very cheap, you should be on your guard. Such a "cheap" mobile phone is either a refurbished mobile phone or an informal channel product, or its accessories are "short of weight".
Identification of batteries, chargers and earphones:
1. The packaging cover of the original electric appliance is dark, which is matt paint, and the color of the assembled electric appliance is bright because it contains fluorescent powder in the middle.
2. There is a small dot next to the contact of BL-5C in the original electricity, but BL-4C does not. This is very important, please pay attention.
3. When buying a battery, you can push the edge of the packaging skin with your nails. The original battery will not peel, but the assembled battery will definitely.
4. The contact color of the original battery is matt and not bright, and the battery will be scratched after being used once.
5. Generally, the labels on licensed mobile phones sold in Chinese mainland are printed in simplified Chinese, while many parallel batteries are sold abroad, so the labels on them are all in English. Some sellers use fake batteries instead of real batteries, which are also printed in Chinese. However, the workmanship of the fake battery is very rough, while the real battery has a neat appearance and no redundant burrs. The outer surface has a certain roughness and feels comfortable, and the inner surface feels smooth, and fine longitudinal scratches can be seen under the light. Moreover, the real battery label has clear handwriting, a battery label corresponding to the battery type, a clear outline of the manufacturer's font, a good brightness of the anti-counterfeiting mark and a three-dimensional appearance.
6. Generally, the price of original electricity will not be lower than 1. If the price is low, you should pay attention.
Nokia earphones are different from ordinary earphones. When you buy them, you are optimistic about the quality. Authentic earphones are very fine in workmanship.
There are so many things mentioned above, but we should pay attention to the following points when shopping:
1. Try the machine: Sellers often agree to let you try the machine, and usually give you a fee card to make free calls. Remember not to use their card at this time, use your own card to play the phone for your friends to try the call quality. Be sure to try it more and try it for a long time, and check whether there are any problems in all aspects of the machine.
2. When testing the machine, remember to take an all-black photo, or take an all-black photo with your hand to see if there is any bad spot on the screen. This bad spot is divided into many colors and will shake all the time. Although it will not affect the use, your screen will not be used for too long.
