1. Look at the mobile phone serial number (IMEI) ^[1]
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: input in the standby state of the mobile phone * # 06 #
A string of numbers displayed on the phone is the serial number of the motherboard, and write it down; remove the battery of the phone and look at the serial number on the white label in the two labels on the back of the phone body, that is, the case serial number, and another label Generally it is a network access license; then look at the IMEI number on the phone box, compare the three to see if they are 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, and you should never 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 authentic, but it can not be 100% sure, because some illegal merchants can fake anything, and the motherboard serial number can use a computer Flashing with software, fake IMEI labels and network access licenses can be bought for a few dollars. For the sake of caution, you should continue to use some methods to identify

2. Look at the outer packaging and instruction manual of the mobile phone. The formal new mobile phone packaging and instruction manual are exquisitely printed, mostly printed on coated paper. The fonts and images are very clear and layered, but the fake packaging boxes are mostly simple. The single-sided paper is imitation, the fonts and images are very dry and rough, the printed handwriting is blurred, and many manuals modified by irregular 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 there must be traces of used instructions in the instructions. Pay attention to them when you buy them.

3.Look at the network access license. < Br There are watermarks on the network access license. The surface color is uneven, ranging from dark to light, thick and thin. The fake ones are mostly copies, and the surface color does not change. If you can't see it, you can also use the currency detector to illuminate the network access permit. There is really a security pattern that will show a red "CMII" pattern. 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.

1. Housing <br The shell of the new machine is tightly connected, and the gap is smooth and burr-free. Refurbished machines generally use imitation original shells, the gaps are uneven, and there are burrs.
The upper and lower parts of the mobile phone case are prone to being closed tightly and leaving a large gap. You can try to insert the seam of the upper and lower covers of the mobile phone with your little finger nails during identification. If it can be inserted, it is a refurbished machine. Mobile phones that have a matte surface like the new one and have small particles are absolutely unavailable. The paint of this machine case is sprayed by JS. As time passes, the paint will fall off (small particles of dust on the case are caused by the vacuum environment operation when painting).
2.In the case

The new machine has a faint sandalwood scent when it is opened. If it is a refurbished machine, JS generally needs to beautify the body. Although the appearance is smooth but not dry enough, there is a rubbery or plastic smell after opening the cover or removing the battery, or The smell of chemicals
3. Keyboard and data cable interface .
Due to the long-term plugging and unplugging of the charger plug and data cable, black scratches on the charging interface of the refurbished machine will be difficult to remove. The keyboard refurbishment machine mostly uses the keyboard on the old machine or is modeled on the keyboard. The common feature of this keyboard is that it feels softer and does not have the toughness of a new keyboard.
4. Charging test.

It's best to charge for a longer time, usually more than 10 minutes. Because there are many refurbished machines that take longer to charge, they will lose power. This is also a very effective way to judge the refurbished machine;
5. SIM card chip contacts and battery contacts.

These two contacts JS cannot be replaced in general. If it is a refurbished machine, then there will be clear friction marks on the contacts of the SIM card chip, which will look shiny, which is caused by excessive friction. If it is a chip that has not been used in a new machine, the contact surface should be matte;
6. Fix the screws.

It mainly depends on whether there are obvious scratches on the screw and the blade interface, and whether there are any scratches on the two rubber pads under the inner screen.
7. Call quality.

Come with a SIM card test machine, call your friend, preferably a fixed phone, and ask the other party how the call quality is, whether the call sound is clear, whether there is noise, current sound, whether there is a sudden drop in volume
8. Price.

Because the parts of the refurbished machine are mostly early products, the quality is also poor, so the price is also low. If you encounter an outrageously low price, but the merchant calls it a parallel phone, it can basically be determined as a refurbished machine.
