Meizu 18X Judge whether to Refurbish the Machine Tutorial
In fact, the situation of refurbished phones is very common in the mobile phone market today. If many small partners buy mobile phones in some unofficial channels, they will have the risk of buying refurbished phones. So it is necessary to check whether Meizu 18X is a refurbished machine. You can come to see the specific viewing methods compiled by Xiaobian for you, which is very convenient.
Meizu 18X determines whether to renovate the machine
Outer packaging and operating instructions
The packaging and instructions of regular new mobile phones are beautifully printed, mostly on coated paper, with clear fonts and images. However, the counterfeit packaging boxes are mostly made of simple single-sided paper. The fonts and images are very dry and rough, and the printing handwriting is vague. Many modified instructions from informal channels are even copied. Some refurbished mobile phones use the original authentic packaging box and instructions, but after all, the machine is old, and its packaging box must have worn the instructions and there must be traces of use, which can be found with more attention when purchasing.
Mobile phone cover
The shell of the new machine is tightly connected, and the gap is flat and smooth without burrs. Refurbishment machines generally use the original casing, with uneven gaps and burrs. The upper and lower parts of the mobile phone casing are prone to loose closure and large gaps. When identifying, you can try to insert your fingernails into the seams of the upper and lower covers of the phone. If it can be plugged in, it is a refurbished machine. And the mobile phone with small particles on the shell surface, which is like a new machine, should never be purchased. The paint on this kind of machine shell is sprayed on, and it will fall off after a long time (the dust particles on the machine shell are caused by the operation without vacuum environment during painting).
Internal smell
There is a light sandalwood smell when the cover of the new machine is opened. If the machine is renovated, it is generally necessary to beautify the body. Although the appearance is smooth, it is not dry enough. After the cover is opened or the battery is removed, there is a rubber smell, a plastic smell, or a chemical smell.
Keyboard and data cable interface
Due to the long-term plugging and unplugging of the charger plug and data cable, the charging interface of the refurbished machine will have black scratches that are difficult to eliminate. However, keyboard refurbishing machines mostly use the keyboard on the old machine or imitate the keyboard. The common feature of this keyboard is that it is soft and has no toughness of the new keyboard.
Charging test
The charging time should be longer, usually more than 10 minutes. Because many refurbished machines will be powered off if they are charged for a long time. This is also a very effective way to judge the refurbishment machine.
SIM card chip contact and battery contact
These two contacts cannot be replaced generally. If it is a refurbished machine, there must be clear friction marks on the contacts of SIM card chips, which look bright. This is caused by excessive friction. If the chip is unused in the new machine, the contact surface should be frosted.
Fixing screws
It mainly depends on whether there are obvious scratches on the screw and blade interface, and whether there are scratches on the two rubber pads under the inner screen.
Call quality
Take your own SIM card to test the machine. Call your friend, preferably a fixed line phone, and ask him or her about the quality of the call, whether the call sound is clear, whether there is noise or current, and whether the volume drops suddenly.
keyboard
Generally speaking, there are Chinese strokes on the keypad of Zhengxing, Shuixing and HongKong mobile phones. The Chinese strokes coordinate with the English letters of the same key. Each Chinese stroke is directly above the middle letter, and the numbers, letters and strokes are all transparent. This is also one of the external features of Zhengxing, Shuixing and Hongkong mobile phones. There are generally no strokes on the keyboard of the water machine. The strokes of English mobile phones before T400 and T500 are usually added after JS. Because the "water machine" keyboard is designed with the English letters in the middle, the Chinese strokes added after it must be on the top, left or right, with a sense of imposition and squeezing. The appearance color is darker than numbers and letters, and it is generally opaque. Now, except for the English version T400 and T500, most of the keyboards of the water conversion machines also have light transmission strokes. Therefore, we would like to remind you that you should pay attention when purchasing. Try to scratch the strokes on the keyboard with your fingernails. If there is any falling off, it is proved that it is a water change product. In addition, the handle of the keyboard of the new phone is relatively flexible and elastic, while the second phone feels relatively soft when used, without the toughness of the new phone.
PCB board logo and mobile phone sticker
For Zhengxing, Shuixing and Honghang mobile phones, the model of the phone is generally marked on the PCB circuit board in the SIM card slot. For some Zhengxing, Shuixing and Honghang mobile phones, although the model of the phone is not marked on the PCB circuit board, the model of the phone must be marked on the back of the phone after the type and SSN marked, or in front of the serial number S/N.
Generally, there will be a white cotton adhesive sticker on the back of the cargo at the screw opening of the fuselage, which reads "maintenance sticker, invalid if torn" in 8 Chinese characters. Of course, it is not enough to judge whether the back sticker is a mobile phone or not, because JS has the means to replace the back sticker. In addition, the back sticker on the mobile phones of the Bank of China, the Bank of Water and the Bank of Hong Kong is different from the European version and the back sticker on the back of the JS. After careful observation, it is still found that the IMEI number of the water change machine is printed vaguely, while the printing of the goods is clear.
Mobile phone IMEI code
IMEI (International Mobile Equipment Identity) is the abbreviation of the international mobile equipment identification code. The international mobile equipment identification code is a 15 digit "electronic serial number", which corresponds to each mobile phone one by one, and is unique in the world. Each mobile phone will be assigned a unique global number after assembly, and this number will be recorded by the manufacturer from production to delivery.
Its composition is 123456-78-901234-5: the first six digits are the "model approval number", which generally represents the model; 7. The 8-digit "final assembly number" generally represents the origin; The next six digits are "serial numbers", which generally represent production sequence numbers; The last digit is usually "0", which is the inspection code and is currently reserved. The IMEI code is pasted on the logo on the back of the phone and read and written in the phone memory. It is also the "file" and "ID number" of the mobile phone in the manufacturer. Now Samsung's new models generally add two digits after the inspection code. For example, the IMEI code is 351005/89/059521/9... 01.
To check the IMEI code of the mobile phone, first enter * # 06 #, check the IME code in the memory of the mobile phone, remember the number, then enter * 2767 * 3855 # to reset the code chip, the mobile phone will automatically restart, and finally enter * # 06 # to check whether the IMEI code has changed. If the number is consistent with the IMEI code on the back of the mobile phone and the external packaging box, and the model approval number is consistent with the mobile phone model, it is proved to be the original product. If it is inconsistent, or becomes a string of garbled codes, or the instructions are not executed, it indicates that the mobile phone is either a water conversion or a refurbishment.
You can use the above steps to determine whether your Meizu 18X is a refurbished machine. There are still many methods. However, if you want to completely avoid buying refurbished phones, you should still recognize the official channels to buy mobile phones, and be alert to informal channels, especially mobile phones that are extremely cheap.
