How to identify a refurbished mobile phone?
Here is an introduction to the experience of how to identify refurbished mobile phones. For mobile phones, we can only feel them by touching and touching, and through the texture of the mobile phone from our hands.
Look at the mobile phone serial number (IMEI).
The so-called mobile phone serial number is the same as the ID card of the mobile phone. Since the IMEI number of each mobile phone is unique, it can generally be used to determine whether a mobile phone is genuine. The determination method is as follows: enter "? * #06 #" under the mobile phone? excluding quotes?, the string of numbers displayed by the mobile phone is the serial number of its main board, write it down; remove the mobile phone battery and look at the serial number on the white label in the two labels behind the mobile phone body? That is, the case serial number, and the other label is generally the network access license. Whether it is the same as the number written down in front; look at the IMEI number on the mobile phone box and compare the three to see if they are all the same. If the main board serial number and the case serial number are inconsistent, or even the main board serial number is not displayed or a string of strange numbers or symbols, then the machine is likely to be repaired or assembled from different parts, and you must not buy it. If the three serial numbers are the same, plus there is a network access license, then it can basically prove that the machine is genuine, but you can't be 100% sure, because today's unscrupulous businesspeople can fake anything, the main board serial number 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 caution, you should continue to verify according to the following method.
Look at the outer packaging and instruction manual of the mobile phone.
The packaging and instructions of regular new mobile phones are beautifully printed, mostly on coated paper, and the fonts and images are very clear and layered, while the counterfeit packaging boxes are mostly simple single-sided paper imitations, the fonts and images are very dry and rough, the printing is blurred, and many modified instructions from informal channels are even copied. There are also some refurbished mobile phones that use the original genuine packaging boxes and instructions, but after all, the machine is old, and the packaging box must be worn. The instructions must also have traces of use. If you pay more attention when purchasing, you can find it.
access network license
There is a watermark on the real network access license, and the color on the surface is uneven, ranging from deep to light, thick to thin; while the fake is mostly copied, and the surface color does not change. If you can't see it, you can also use the money detector to take a picture of the network access license. The license really has an anti-counterfeiting pattern inside? It will show a red "CMII" pattern.?, while the fake pattern is blurred. The real network access license is usually printed with a needle printer, with clear numbers and needle dents. The fake network access license is printed by an ordinary printer, and the numbers are not very clear and there are no dents. Generally speaking, the network access license is more difficult to fake, after all, the equipment required for counterfeiting is relatively expensive. In addition, you can also check the authenticity of the network access license online, which will not be explained in detail here.
Look at the phone case.
The "key parts" of the brand new mobile phone are protected by the manufacturer's film, such as the inner and outer screens of the new mobile phone, the lens of the camera phone, etc., because as long as these parts are touched, fingerprints, dust and traces of use will be left. New, after fingerprints are left on the mobile phone, it is likely to be a refurbished mobile phone. The gap between the upper and lower cases of the mobile phone, the gap around the keyboard, and the charger slot. The shaft of the flip phone will also leave traces of use. You should also pay special attention.
The shell used in refurbished mobile phones is generally imitation of the original, or the old shell is carefully polished, so the front and rear parts of the mobile phone shell are prone to tight closure and large seams. The identification method is to use your fingernails to see if it can be inserted into the seams of the upper and lower covers of the mobile phone. If it can be inserted, it is to assemble the shell. A brand new mobile phone, no scratches on the surface, no gaps, clean and new sound hole mesh cover, no friction and smooth feeling. The battery touchpoint is new, the mobile phone touchpoint has almost no traces, the SIM card touchpoint has no signs of long-term compression, and the screen has no signs of aging. Q-screen mobile phones are especially easy to distinguish. Pay attention to the keyboard, paint, and signal sensitivity response.
For those mobile phones that have not replaced the case, the merchant sprays it with a spray like a cleaner before selling, and the surface of the old case immediately appears a matte effect like the new one. If the buyer does not check it carefully, it will be fooled by unscrupulous merchants. However, it will not take long for the spray paint of the case to fall off. When you buy it, you must carefully observe the case, because no matter how good the merchant's craftsmanship is, it is not as advanced as the original equipment. If you check it carefully, you can see a little bit of dust. It is caused by not working in a vacuum room during painting. If it is a flip machine, you can also check the joint of the flip, because sometimes, even if the seller treats the surface of the machine well, these places will inevitably leave some traces of dust. In addition, check whether the fuselage screws are brand new and whether there are any traces of screwdrivers being twisted. What's more, many new mobile phones have a distinct sandalwood smell, while old mobile phones and shell changers generally do not have such a smell, or have a peculiar smell left by processing.
See warranty
Ask the dealer for the warranty period of the machine and ask for a regular 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 the warranty period is relatively short. If the seller says they are responsible for the warranty, they cannot agree, because regular mobile phones are generally guaranteed by the whole country. If the seller cannot do this, then there must be a problem with the mobile phone.
Look at the price
As the saying goes, if you are greedy for small and cheap, you will lose a lot. Before buying a machine, it is best to check the price of the mobile phone in the local newspaper or website. If the price quoted by JS is "very cheap", you should be vigilant. Such a "cheap" mobile phone is not a refurbished mobile phone or an informal channel product, but an accessory that is "short of weight". It is recommended to buy a mobile phone in a reputable and service-oriented regular sales store with a complete three-guarantee certificate? A valid delivery ticket and three-guarantee card. In this way, when there is a problem with the machine, the legitimate rights and interests can be guaranteed.
