How does Lenovo mobile phone distinguish between true and false?
(1). Carefully check the screen for traces, data cable, earphone hole, speaker hole and tape hanging hole for dust.
(2) Look carefully at whether there are dial marks on the battery bolt of the fuselage, whether there are rotation marks on the rotating shafts of the upper and lower covers, and whether there are indentations on the two protrusions on the upper cover.
(3) Carefully check whether there are records in WAP, voice function and call record information function.
(4) Carefully check whether the contact point between the SIM card and the battery of the fuselage has wear marks (distinguish other contact points).
(5) Check whether the gap at the joint of the shell is even, whether it is below 1MM, whether there are pry marks, and whether there are pry marks at the two sealing points under the screen in the upper cover.
(6) Look carefully at whether there is rotary printing, painting and inking (magnifying glass can be used) on the fixed gong nail of the fuselage, and whether there are pry marks on the trademark.
2. Inquire about the mobile phone network access license: refer to how to identify licensed products!
3. Inquire about the mobile phone serial number IMEI: refer to how to identify licensed products!
Detailed methods for identifying new machines:
1. See serial number (IMEI).
Mobile phone serial number is the same as ID card, and the IMEI number of each mobile phone is unique. Generally speaking, it can be used to judge whether a machine 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 chassis. 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 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 different, then the machine is probably repaired or assembled. If all three serial numbers are the same and there is a network access license, it can basically prove that this machine is genuine. However, it is not 100% sure that the serial number of the motherboard can be written by computer and software, and the fake serial number label can be bought for a few dollars. For the sake of caution, we should continue to verify according to the following methods.
Note: The seventh and eighth codes of mobile phone serial number used to indicate the origin of mobile phones, but this method is no longer used to distinguish the origin of newly produced major brands of mobile phones. By analyzing the origin of mobile phone serial number to explain the quality of mobile phone, there is no theoretical basis at present, so please don't blindly follow.
2. Look at the machine packaging and instructions.
The packaging and instructions of the regular new machine are beautifully printed. Nokia's high-end models are mostly printed on coated paper, and the fonts and images are clear and layered. 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.
3. Look at the network access license
There is a watermark on the network access license, and 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. There is really an anti-counterfeiting pattern in it, but the fake pattern is very vague. 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.
Step 4 look at the phone case
When you open the new machine, you will obviously notice that the "key parts" of the machine are covered with film for key protection, such as the inner screen, the outer screen and the camera. As long as the used mobile phone leaves traces. In addition, dust and traces of use are inevitable when renovating the machine. (Ouku will check the appearance of each mobile phone and try to avoid leaving fingerprints when checking. Please forgive me if I accidentally leave fingerprints on the phone case. )
The gap between the upper and lower casings of the machine, the gap around the keyboard and the charger slot are all places that are 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.
5. Look at the screws and seams
You can check whether the seams of the mobile phone are even. Generally, the shell quality of refurbished machines is poor, and the gap will be narrower and wider.
In addition, check whether the screws of the fuselage are brand new and whether there are any traces of screwdriver screwing.
6. Look at mobile phone accessories
The new machine of the regular manufacturer has a full set of original accessories, which should be charged at least once. 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 the mobile phone is likely to be tampered with.
7. Look at the usage record and running status of the mobile phone.
Look at the records of games, short messages, phone books, call records, homemade ringtones and other items in the mobile phone. If there are, most of them are not brand-new mobile phones. 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.
8. Look at the warranty
Regular dealers will take the initiative to issue tickets and enjoy the service of three guarantees nationwide. 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.
9. Look at the price
As the saying goes, greed is cheap, and big losses. Before buying a machine, you'd better find out the price of a mobile phone online. 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".
Have a complete and effective ticket and warranty card, so that the legitimate rights and interests can be guaranteed when there is a problem with the machine.
10. odor
Most new machines have a special sandalwood smell when electronic products leave the factory, which is by no means imitated by ordinary perfume. However, old machines and shell changers generally do not have this smell, or there is a smell left during processing.
