2. Shell, the shell commonly used for refurbished machines is original, so the front and rear parts of the mobile phone shell are easy to close tightly, leaving a big gap. The identification method is to insert the little finger nail into the seam between the upper and lower covers of the mobile phone! If you can plug it in! Is to assemble the shell, for those mobile phones that have not changed the shell, spray a layer of mist like a cleaner, and the surface of the old shell will immediately appear a matte like a new machine. Buyers don't look carefully, so most of them can get away with it, but after a long time, the paint on the shell will fall off. 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 closely, you can see some particles (dust, which is caused by not working in a vacuum room when painting).
3. Keyboard and Interface Due to the long-term plugging and unplugging of the charger plug, the charging interface of the refurbished machine will have black scratches, and the refurbished machine mostly uses the keyboard on the old machine or the imitation keyboard! This kind of keyboard feels soft! Not as strong as the new keyboard.
4. Charging, preferably for a long time, usually 10 minutes or more. Because there are many refurbished machines that will run out of power after a long charging time. This is also a very effective way to judge the refurbished machine.
5.SIM card chip contacts are the same as battery contacts, which cannot be replaced by JS! Therefore, it can be seen that the refurbished machine has obvious contact and friction marks.
6. Fixed screw, the fixed screw part can't completely judge the authenticity of the mobile phone yet! But it can also be used as a reference, mainly to see if there are obvious scratches on the contact surface between the screw and the blade. If there is, there is no need to judge anything else! No, just look at other identification methods.
7. Price, because the spare parts of refurbished machines are all early products with poor quality, so the price is very low. If you encounter this kind of mobile phone that is ridiculously low in price but is called parallel imports by merchants, you can basically conclude that it is a refurbished machine.
8. Quality: After the previous precautions are passed, it is a trial run, and JS is happy to let you try. Usually he will give you a card with no money and ask you to call 1 12. Actually, you. You can bring your own money card, call your friend (landline) and ask him how the call quality is. Identification method of refurbished mobile phone 1: carefully check whether there are traces on the screen, and whether there are dust on the data cable, earphone hole, speaker hole and strap hole. 2. Look carefully at whether there are dial marks at the battery lock of the fuselage, whether there are rotation marks at the rotating shaft of the upper and lower covers, and whether there are indentations at the two protrusions of the upper cover. 3. Carefully check whether there are records in WAP, voice function and call record information function 4. Shells. The shell of the new machine is tightly attached, and the gap is smooth and smooth without burr. Whether the gap at the joint 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. Refurbishers generally use imitation original shell, with uneven gaps and burrs. The upper and lower parts of the mobile phone shell are easy to be closed loosely, leaving a large gap. When recognizing, you can try to insert a small nail into the gap between the upper and lower covers of the mobile phone. If it can be plugged in, it is a refurbished machine. The surface of the shell is frosted like a new machine, and the mobile phone with small particles is absolutely not to be purchased. The paint on the machine shell was sprayed by JS. After a long time, the paint will fall off (the dust particles on the shell are caused by the operation without vacuum environment when painting). 5. smell it. The new machine has sandalwood, which is different from ordinary detergent and perfume. There should be no wax and oil on the fuselage (if there is, it is beautified by JS). 6. Carefully check whether the contact point between the SIM card and the battery of the fuselage has wear marks. The contact surface of the chip not used in the new machine should be frosted. 7. Compared with the new machine, the elasticity of the keys and the brightness of the internal and external display screens, the strokes of the water machine keyboard are engraved, and the light distribution is not very uniform. The keyboard of the new machine feels more resilient and elastic, and the second mobile phone feels softer when used, so there is no new machine. 8. Look carefully at whether the fixed pins of the fuselage are rotary printing, painting and inking (a magnifying glass can be used), and whether there are pry marks on the trademark. Mainly depends on whether there are obvious scratches at the interface between the screw and the blade, and whether there are pick marks on the two rubber pads below the inner screen. 9: Take a pure black photo and a pure white photo to see if there are any white spots and dark spots. 10: Speak clearly, without noise or current, and the volume is loud enough for normal use with headphones plugged in. Cover the antenna with your hand, and the signal attenuation shall not exceed two squares at most. Otherwise, the price won't be too big, so don't be greedy and cheap ~)*# 1234# Software version (this can be changed, and many friends who buy Eurowater will display the licensed version after inputting it. This is normal ~ it's convenient for you to use, so don't worry ~)*#2222# hardware version * # 9998 * 228 # temperature display (some buy real water and electricity, but the input doesn't respond) Software version meaning: area code definition: -D908ZCGA2 as an example -D908ZCFJ 1DX Eurowater D908 indicates the machine model- After the reset, the mobile phone will automatically restart (after the reset, the IMEI code will be restored to the factory state, and the number changed by the machine can also be restored. Plus: this will not change the version of the computer because of the reset, nor will it change the Chinese version to the English version. Don't worry, thank you 132 floor for your questions. I'm here to answer! ! ! Don't try it if it's okay. Mine was completely reset by my brain fever, and my tears ~) After the phone is automatically restarted, enter *#06# to check the serial number and write it down, and compare it with the serial number on the label in the battery compartment (the IMEI number of parallel imports is printed vaguely).
