This usually confirms that it's not a refurbished machine.
Retreader is a mobile phone that takes back some second-hand mobile phones and cleans them with chemical liquids, replaces the case, and is sold as a new phone with batteries, chargers (counterfeit) and packaging. There are several ways to identify whether it is a refurbished machine:
1 Outer packing and instruction manual
The packaging and instructions of the regular new mobile phone are beautifully printed, mostly on coated paper, the font and image are very clear and have a sense of hierarchy, while the fake packaging box is mostly a simple single-sided paper imitation, the font and image are very dry, rough, and the printing handwriting is fuzzy, and many informal channels of modified instructions are even photocopied. There are some refurbished mobile phones, although the original genuine packaging box and manual are used, but after all, the machine is old, its packaging box must be worn, and the manual must have traces of use, which can be found when you pay more attention to the purchase.
2 Mobile phone cover
The new machine shell is compact, the gap is smooth and smooth, no burrs. The refurbished machine generally uses the imitation original shell, the gap is uneven, there are burrs, and the upper and lower parts of the mobile phone shell are easy to close loosely and leave a large gap. To identify, try to insert your pinkie nail into the seam of the top and bottom cover of the phone. If it fits in, it's a retreader. The surface of the shell is sanded like a new machine, and there are small particles of mobile phones, it is absolutely not to buy. The paint of the shell of this machine is sprayed up, and after a long time, the paint will fall off (the dust particles on the shell are caused by poor spray painting, and the reasons are many, such as the spraying environment, the spraying pigment, the spraying material, etc.);
3 Internal odor
The new machine has a light sandalwood smell, if the refurbishment machine, generally to the fuselage for a beauty, although the appearance is smooth but not dry enough, open the cover or remove the battery after the rubber smell, plastic smell, or chemical odor;
4 Keyboard and data cable ports
Due to the long-term insertion and removal of the charger plug and data cable, the charging interface of the refurbished machine will appear black scratches that are difficult to eliminate. The keyboard refurbishment machine mostly uses the keyboard on the old machine or is copied the keyboard. The common feature of this keyboard is that it feels soft and has no toughness of the new keyboard.
5 Charging Test
The charging time is better, generally more than 10 minutes. Because there are many retreaders charging a little longer will power off. This is also a very effective way to judge the refurbished machine;
6SIM card chip contact and battery contact
These two contacts are generally impossible to replace. If it is a refurbished machine, then the SIM card chip contacts will leave clear friction marks, looking shiny, which is caused by too much friction. If it is a new machine has not been used chip, the contact surface should be frosted;
7 Fixing Screws
Mainly look at the screw and knife interface part has no obvious scratches, the two rubber pads under the inner screen have no pick marks.
8 Call Quality
Bring your own SIM card test machine, call your friend, preferably a fixed phone, ask the other party about the quality of the call, whether the call sound is clear, there is no noise, current sound, the volume of the phenomenon of sudden decline;
9-keyboard
For example, there are Chinese strokes on the keyboards of Samsung, Water and Hong Kong mobile phones, and the Chinese strokes are coordinated 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 Samsung Zhengxing, Waterline, and Hong Kong mobile phones. There is generally no stroke on the keyboard of the water machine, and the English mobile phone strokes before T400 and T500 are generally added after JS, because the \"water cooler\" keyboard is designed so that the English letters are centered, the Chinese strokes added after must be on, left or right, there is a sense of imposition and extrusion, the appearance color is deeper than the numbers and letters, and is generally opaque. In addition to the English T400 and T500, most of the keyboards of the water reform machines also have transparent strokes. Therefore, in this remind you to buy must pay attention to, may wish to try to use nails to scratch the strokes on the keyboard, if there is a falling off phenomenon is proof of water change goods. In addition, the feel of the new keyboard is more resilient and flexible, while the use of the second phone feels softer, without the toughness of the new machine.
10PCB circuit board logo and mobile phone back
Samsung is line, water line, Hong Kong bank mobile phone, generally in the SIM card slot PCB circuit board marked with the model of the phone, such as SGH-S308, SGH-S208, SGH-T108, SGH-T408 and so on. The European version of SGH-300, SGH-S200, SGH-T100, SGH-T400 and other mobile phones are marked SGH-S300, SGH-S200, SGH-T100, SGH-T400, respectively. There are also some Samsung, water, Hong Kong mobile phones, such as T208, S108, etc., although there is no mark on the PCB circuit board on the model of the phone, but on the back of the phone labeled TYPE (TYPE), behind the SSN, or in front of the phone serial number S\/N, will be marked with the model of the phone.
Generally, there will be a white cotton adhesive sticker on the back of the fuselage screw port, which says \"Maintenance label, tear invalid\" 8 Chinese characters.
Of course, it is not enough to judge whether the back sticker is a line or a water phone, because JS fully has the means to replace the back sticker. I have witnessed a Samsung S100 mobile phone labeled S108 on the back.
Of course, the back sticker on the line, water line, Hong Kong Bank mobile phone and the European version of the mobile phone, as well as the back sticker affixed after JS is still different, careful observation will find that the IMEI number of the water reform machine is printed more blurred, and the printing of the goods is clearly visible.
11 IMEI of the mobile phone
IMEI(International Mobile Equipment Identity) is the abbreviation of the international mobile equipment identification code, the international mobile equipment identification code, is composed of 15 digits of the \"electronic string number\
Its composition is 123456-78-901234-5: the first 6 digits are the \"model approval number\
To check the IMEI code of the mobile phone, you should first enter *#06#, check the IMEI code in the memory of the mobile phone, remember this number, and then enter *2767*3855# to reset the chip, and the phone will automatically restart, and finally enter *#06# to check whether the IMEI code has changed. If this number is consistent with the IMEI code on the back of the mobile phone and the outer packaging box, and the model approval number is consistent with the model of the mobile phone, it is proved that the original product is authentic. If it is inconsistent, or becomes a string of garbled codes, or the instructions are not executed, it proves that the phone is either a water modification machine or a refurbished machine.
Everyone remember that the so-called \"three codes in one\" of online JS basically can't explain what, and many profitmakers have changed the IMEI, that is, changed a \"legal\" IMEI code that compares the new factory date (available on the official website).
12 Network access license
There are watermarks on the real network license, and the color of the surface is uneven, deep and shallow, thick and fine; The fake ones are mostly photocopies, and the surface color does not change. If you can't see it, you can also use the detector to take a look at the network license, there is really an anti-counterfeiting pattern inside, and it will show a red \"CMII\" pattern. And fake patterns are blurry. The real access card is generally printed with a needle printer, the numbers are clear, and carefully look at the indentation of the needle; The fake access license is printed by an ordinary printer, the numbers are not very clear, and there are no dents. In general, the network license is more difficult to fake, after all, the equipment required for fraud is relatively high in cost.
In addition, you can check the authenticity of the network license online.
The operation method is:
1. Access the telecommunications equipment access certification network, the mobile phone attached to the network license number and access license sign the third line of the \"scrambling code\
2. If the Internet is not convenient, you can also call the official authenticity inquiry phone for manual inquiry. You can also use mobile phone SMS to identify, send \"RW# access license number # 'scramble code' # mobile phone body number\" to 9500, and the telecom equipment access certification management information system will automatically reply to consumer identification information.
mobile phone spare parts
If it is a new mobile phone from a regular manufacturer, there should be a full set of original accessories, at least one charge.
13 Usage Records
If there is any record of games, text messages, phone books, call records, and self-made ringtones in the mobile phone, there is a very big suspicion of renovation. In addition, in the normal use of the process, the machine frequently automatically shut down or crash, then it is certain that the motherboard or software of this mobile phone has some problems.
14 Warranty
Ask the dealer about the warranty period of the machine and ask for a proper invoice. Refurbished mobile phones can not enjoy all the rights and interests of the regular mobile phone \"three guarantees\
15 Price
As the saying goes, penny wise eats pound foolish. Before buying the machine, it is best to understand the price of the mobile phone in the local newspaper or website, if the price is \"very cheap\
