Recognition method of refurbished mobile phone

The first trick is to look at the mobile phone serial number (IMEI)
The so-called mobile phone serial number is just like the mobile phone's ID card. Because the IMEI number of each mobile phone is unique, it can be generally judged from this whether a mobile phone is genuine. The judgment method is as follows: In the standby state of the mobile phone, enter "* # 06 #" without quotation marks. A series of numbers displayed on the mobile phone is the serial number of the motherboard, and write it down. Remove the mobile phone battery and look at the back of the phone's body. The serial number on the white label of the two labels is the serial number of the case, and the other label is generally a network access license. Whether it is consistent with the numbers written down before; look at the IMEI number on the phone box, compare the three to see if they are all the same. If the motherboard serial number is inconsistent with the case serial number, or even the motherboard serial number is not displayed or a strange series of numbers or symbols, then this machine is likely to be repaired or assembled with different parts. Do not buy it. If the three serial numbers are the same, and if there is a network access license, then this machine can basically be proved to be genuine, but it can not be 100% sure, because the current illegal merchants can fake anything, the motherboard serial number can be used Computer and software flashing, fake serial number labels and network access licenses can be bought for a few dollars. For the sake of caution, you should continue to verify according to the following method.
The second trick is to look at the packaging and instruction manual of the mobile phone
The packaging and manuals of regular new mobile phones are exquisitely printed, mostly printed on coated paper. The fonts and images are very clear and layered, while the fake packaging boxes are mostly imitations of simple single-sided paper. The fonts and images are very dry and rough. The printed writing is blurred, and many of the manuals modified by informal channels are even copied. There are also some refurbished mobile phones that use the original authentic packaging and instructions, but after all, the machine is old, the packaging must be worn, and the instructions must have used traces. Pay attention to them when you buy them.
The third trick to see the network license
Really there are watermarks on the network access permit, the surface color is uneven, there are dark, light, thick and fine; while the fake ones are mostly copy, the surface color does not change. If you can't see it, you can also use the currency detector to take a picture of the network access permit. There is really an anti-counterfeiting pattern inside. It will show a red "CMII" pattern. , While the fake pattern is blurred. Real network access cards are usually printed with a dot-matrix printer. The numbers are clear. Look carefully at the dents on the needles. The fake network access permits are printed by ordinary printers. The numbers are not very clear and there are no dents. Generally speaking, the network access license is relatively difficult to counterfeit, after all, the equipment required for counterfeiting is relatively high in cost. In addition, you can also check the Internet to check the authenticity of the network access license, which will not be described in detail here.
The fourth track is to look at the phone case
When you open a brand new mobile phone, you will notice clearly that there are manufacturers' films in the "key parts" of the mobile phone for key protection, such as the inner screen, outer screen of new mobile phones, camera lens of mobile phones, etc., because these As long as the part touches, it will leave fingerprints. So when you see the fingerprint on your new phone, let the vendor explain how you do n’t listen. In addition, dust and traces of use are also difficult to avoid when refurbishing a mobile phone. The gap between the upper and lower cases of the mobile phone, the gap around the keyboard, and the charger slot are all places that are easy to "contaminate dirt". You will also have used traces on the shaft, so please pay special attention too.
Refurbished mobile phones generally use the original shell, or the old case is carefully polished, so the two parts of the front and back of the phone case are prone to close tight, leaving a large seam, the identification method is to test with a fingernail Test if you can insert the seams of the upper and lower covers of the phone. If you can insert them, it is to assemble the case.
For those mobile phones that have not been replaced, a spray of a cleaner-like spray is used before the sale. The surface of the old case will immediately have a matte effect like the new one. If the buyer does not look carefully, it will be illegal. It ’s confusing, but it wo n’t take long for the spray paint on the case to come off. When you buy it, you must carefully observe the case, because the craftsmanship of the merchant is no better, and the original equipment is not advanced. If you look closely, you can see To a small particle is 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, no matter how well the dealer treats the surface of the machine, some traces of dust will inevitably be left in these places. Also check whether the body screws are brand new and there are no traces of the screwdriver. It should be noted that many new mobile phones have an obvious sandalwood scent, while old mobile phones and shell changers generally do not have such a taste, or have an odor leftover from processing.
Fifth trick to see mobile phone accessories
If it is a new mobile phone from a regular manufacturer, there should be a full set of original accessories, and at least one charge and one charge. The accessories of refurbished mobile phones are generally not complete or are not the original products. Before purchasing, it is best to go to the relevant website to find out what the standard original accessories are. In addition, if there are scratches on the plugs of the charger and headphones, then this phone is probably not brand new.
Sixth trick to see usage records
Take a look at games, text messages, phone books, call logs, self-made ringtones, and more on your phone. Records of whether the project has been used or not, if any, there are very large renovation suspicions. In addition, during normal use, if the phone frequently shuts down or freezes frequently, it can be said that there is a certain problem with the phone's motherboard or software.
Seventh trick to see the warranty
Ask your dealer for the warranty period of your phone and ask for a formal invoice. Refurbished mobile phones cannot enjoy all the benefits 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 nationwide. If the seller can't do this, then there must be a problem with the phone.
The eighth trick to see the price
As the saying goes, greed is cheap and suffers a lot. Before buying a mobile phone, consumers are advised to check the price of the mobile phone in the local newspaper or website. If the price quoted by the mobile phone dealer is "very cheap", you must be alert. Such "cheap" mobile phones are not refurbished Mobile phones and products from non-formal channels are accessories that are short of two. Consumers are advised to purchase mobile phones from reputable and service-oriented regular sales stores, and have a complete three-pack certificate to effectively send them.
