How to identify whether a mobile phone is newer?

Refurbishing a mobile phone is actually collecting the original movement, shell or outer packaging for maintenance or processing, and then selling it as a new machine. There are many types, mainly: 1. Old machines with circuit board problems are repackaged and sold after maintenance or parts assembly, and their performance is the most unstable; 2. The shell of the normal old machine is sold as a new one after being treated or replaced; 3. Irregular channel vendors' machines are sold as new products after being refreshed and repackaged by software, which lacks the stability of general software for such machines. These refurbished machines have a common feature, that is, they can't enjoy after-sales service like regular licensed products. ★ The following is how to identify the experience of refurbished mobile phones. Let's have a look. ★ Look at the mobile phone serial number (IMEI). Just like the ID card of a mobile phone, the IMEI number of each mobile phone is unique. Generally speaking, you can judge whether a mobile phone is genuine or not. The discrimination method is as follows: enter * # 06 # in the standby state of the mobile phone, and a string of numbers displayed by the mobile phone is the serial number of its motherboard, so write it down; Remove the battery of the machine and look at the serial number on the white label in the two labels behind the fuselage, that is, the serial number of the casing. The other label is usually the network access license. Whether it is consistent with the previous figures; Look at the IMEI number on the box of the machine and compare the three to see if they are all consistent. If the serial number of the motherboard is different from the serial number of the chassis, then the machine is probably repaired or assembled, so don't 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 100% sure, because JS can fake everything now, the serial number of the motherboard can be written by computer and software, and fake serial number labels and network access licenses can be bought for a few dollars. In order to be cautious, we should continue to verify from the following aspects. ★ Look at the outer 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. However, counterfeit packaging boxes are mostly copied on simple single-sided paper, with rough fonts and images and blurred printing handwriting. Many instructions modified by informal channels are even plagiarized. There are also some refurbished machines that use original packaging boxes and instructions, but after all, the machine is old, the packaging box must be worn, and the instructions must have traces of use. You can find it when you buy it. ★ Look at the network access license. There is a watermark on the network access license. The surface color is uneven, deep and shallow, thick and thin; Most of the fakes are imitations, and the surface color has not changed. If you can't see it, you can also use the money detector to look at the network access license. If there is an anti-counterfeiting pattern inside, the red "CMII" pattern will be displayed. The false pattern is blurred. The real network access license is usually printed with a stylus printer, and the figures are clear. Look carefully at the dent caused by the pin, but the fake network access license is printed by an ordinary printer, the number is not very clear, and there is no dent. Generally speaking, it is difficult to fake the network access license, after all, the equipment cost required for fraud is relatively high. In addition, you can also check the authenticity of the network access license through online inquiry, which will not be explained in detail here. ★ When you look at the phone case and open the 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 and the camera. As long as these parts touch, they will leave fingerprints. Don't listen to JS's explanation when you see the fingerprints on the mobile phone. In addition, dust and traces of use are inevitable when renovating the machine. The gap between the upper and lower casings of the machine, the gap around the keyboard and the charger slot are all places where it is easy to "hide dirt and shelter evil people", and the rotating shaft of the clamshell machine will also leave traces of use, so special attention should be paid. ★ Generally, the casings used for renovating mobile phones are original or carefully processed old casings, so the front and rear parts of the casings of mobile phones are easy to close loosely and have a large gap. The identification method is to try whether the fingernail can be inserted into the gap between the upper and lower covers of the mobile phone. If it can be inserted, the housing is assembled. For machines that don't replace the shell, JS uses a mist similar to detergent before selling, and the surface of the old shell immediately appears a matte effect similar to that of the new machine. If you don't look carefully, JS will get away with it, but it won't take long for the shell to be painted. Be sure to look at the shell carefully when you buy it, because JS technology is no matter how good it is, and it is not as advanced as the original equipment. If you look carefully, you can see a small particle, dust and dust. ★ If it is a clamshell machine, you can also check the joint of the clamshell machine, 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 screwing. More importantly, many new mobile phones have obvious sandalwood smell, while old mobile phones and shell changers generally do not have this smell, or the smell left during processing. ★ Look at mobile phone accessories. The new machine of the regular manufacturer has a full set of original accessories, at least one charge and one charge. The accessories of refurbished mobile phones are generally incomplete or not original. Before buying, it is best to go to the relevant website to find out what the original accessories are standard, so as to avoid JS buckle accessories. In addition, if scratches are found on the plug of the matching charger and earphone, then this mobile phone is probably not brand new. ★ Look at the usage records to see if there are any usage records of games, short messages, phone books, call records, homemade ringtones and other items in the mobile phone. If there is, there is a great suspicion of renovation. In addition, during normal use, the machine frequently shuts down or crashes automatically. It can be said for sure that there is something wrong with the motherboard or software of this mobile phone. ★ Look at the warranty and 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 short warranty period. If the seller says 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. ★ Look at the price, as the saying goes, greed is cheap, big losses. 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 of JS newspaper is "very cheap", be on your guard. Such a "cheap" mobile phone is either a refurbished mobile phone, an informal channel product, or an accessory that is "short of weight". It is recommended to buy mobile phones in regular stores with good reputation and heavy service, with complete three-guarantee vouchers, valid invoices and three-guarantee cards. In this way, the legitimate rights and interests can be guaranteed when the machine has problems. Smell Most new machines will have a special smell when electronic products leave the factory, which is by no means imitated by ordinary perfume. A similar fragrance can be smelled on the newly manufactured computer accessories. Refurbished ones generally don't have this taste. Even if JS is fragrant, it is by no means the smell of a new machine. According to reports, there are many kinds of imported brand mobile phones with parallel imports. South Korea's Samsung mobile phones with the most parallel imports have five types of goods on the market: A goods, genuine licensed products; B goods are licensed, the source is in doubt, but it can be guaranteed; C goods are parallel imports, most of which are assembled in Guangdong; D goods are also parallel imports, but assembled in Korea; And electronic goods. This is a revised mobile phone. There is no such style at all. It uses the body of other mobile phones. According to experts, under normal circumstances, when buying a mobile phone, you can distinguish parallel imports from three aspects: the outer packaging of parallel imports is rough, the handwriting of the instructions is illegible, and the paper is ordinary one-sided paper, which has poor hand feeling; There is no mark on the contact part between the battery and the fuselage, and parallel imports often like to stick a mark, which is actually broken glass; The novelty and delicacy of the action. According to insiders, the difference between licensed goods and parallel goods now mainly depends on the body number and license plate number. It is more certain to see whether the production of mobile phones is approved by the Ministry of Information Industry. Consumers can also use the online inquiry system. The usual operation method is to access the network access authentication network (w ww) of telecommunication equipment. tenaa。 com。 Cn), and input the network access card number attached to the mobile phone, the "scrambling code" in the third line of the network access permission sign and the mobile phone body number one by one. The website will inform consumers of the authenticity of the mobile phone, and dial the number "(*) # 06 #" to get the mobile phone body number. If the network is inconvenient, you can also dial 0 10-82058767, 820503 13 for manual inquiry. You can also use SMS authentication, send "RW # network access certificate number #' scrambling code' # mobile phone body number" to 9500, and the telecommunication equipment network access authentication management information system will automatically reply the consumer authentication information.
