How to tell the authenticity of Nokia mobile phone
First of all, we should observe carefully with our eyes.
1. access card: the handwriting should be clear and concave-convex, and the word CMII should be written under the irradiation of the money detector.
2. Battery: A. There is a small word "Nokia" in the "I" of "Nokia";
B. The charger limits the voltage to 4.2V instead of 4.2 V, and the difference lies in whether there are spaces;
C only use the charger approved by Nokia, and the two "mouths" on the word "device" are very small;
D. The raised "Nokia" has a strong three-dimensional effect.
E. the surface gloss of the battery contact metal sheet is not high. If you look closely, you should find that the metal sheet is covered with a protective film and the grid lines are very shallow. If it is a new battery, it should be unopened, without electricity, and the contact protection film is complete, without any marks of squeezing and scratching.
Second, it is natural to use IMEI code manually after eye observation, and the three codes are integrated (mobile phone, battery and outer packaging).
Enter *#92702689# in standby mode.

Page 2 Date of production
Page 3 Date of purchase
Page 4 Maintenance Date
Because it is a new machine, the above information should be close to the initial value, that is, close to 0 is correct, because it may be a machine that others have tried. If the incoming message is displayed for too long, it is a refurbished machine.
In standby mode, enter: *#0000# Check the software version number.
The first line shows the version number of the native software.
The second line shows the software release date.
The third line shows the phone model information.
You can check online after you buy it, and you can talk to the mobile phone manufacturer in advance, because it is stipulated that the mobile phone can be fully refunded within seven days after sale. If you find that the goods are not the right version, you can naturally find trouble with the mobile phone manufacturer.
Three outer packing boxes
1) The boxes of the new mobile phones are all brand new, except that there is no dirt or handwriting on the boxes. And there is no re-labeling-especially those with IMEI code (because some mobile phones have been repaired, manufacturers label them and merchants resell them).
2) prevent mobile phone smuggling; The box should be marked in Chinese, including product name, model, factory name, address, contact number and other information. If the English logo on the box is incomplete, it may be a smuggled mobile phone.
3) prevent replacement of accessories; If the box is sealed (such as Ericsson, Philips, Siemens, Samsung, etc.). ), remember to open and tear the seal yourself (because some businesses use a hair dryer to open the seal, which is invisible by scraping the seal), so that you can check whether it has been opened. And some merchants deliberately unpack in front of you, which is generally a fake action of the merchants. In fact, the packaging may have been unpacked and the internal accessories have been replaced. What you see is "unpacking", so you won't have doubts.
After unpacking, first check the category and quantity of the standard configuration of the manufacturer. Generally, it should include: body, battery, charger, earphone, waist clip, product instruction manual, warranty card, accessories instruction manual, etc. What needs to be emphasized here is that the warranty card is the guarantee for the after-sales service of each mobile phone. If there is no formal warranty card from the manufacturer, don't buy it. Some mobile phone warranty cards also indicate the body code, pay attention to check whether it is consistent with the body code marked on the packaging box.
Four batteries
1) The "NOKIA" logo "i" on the genuine Nokia battery is composed of very small Nokia characters, and the instructions and bar codes on the battery should feel obviously concave and convex. Authentic mobile phone boxes all have original factory certificate, original barcode card, original factory warranty card, and parallel imports do not.
2) Appearance of the battery: The surface of the metal sheet of the new battery is covered with an oily substance (which looks unclean), and it is even, and there should be no scratches. However, if the surface is bright or scratched, alcohol may be used for cleaning, and the performance of the battery may not be guaranteed.
Battery model: for example: genuine Nokia 82 10 original lithium battery model is BLB-2, with a capacity of 650mAh and a voltage of 3.6V, and now it is 750mAh.
3) NOKIA trademark: When we identify the battery, please carefully check that the I of the battery trademark NOKIA is composed of the small letter Nokia.
4) Label text: The text on the battery label is etched on the battery surface, just like the black words on the computer keyboard. Fake batteries are usually affixed with a self-adhesive paper.
5) Standby time: 800mAh battery stands by for about 3 days (shut down at night, and the daily call time is about 12 minutes). IT 168 nokia forum. _9K6D(~-s5O，`
6) Pay attention to whether the metal contacts of the battery cross (if they cross, they must not).
7) battery origin: the battery is produced by Shenzhen Sanyo Huaqiang. The original charger is provided by Flextronics Technology (Zhuhai) Co., Ltd.
8) Nokia's logo has been carved many times, in which the I is composed of the tiny word "Nokia", and the bar code feels uneven. The two mouths above the word "charger" are larger than the two below.
Five fuselage
1) requires shell replacement on the spot. When disassembling the shell, please carefully check all the parts that can be seen, and be clean and seamless;
2) The keyboard of the new machine feels tight when pressed. If you are more comfortable and elastic, you should be careful.
3) Check whether the phone head is worn or fingerprinted, whether the screen protective film is flat and whether the back cover is loose.
4) Check whether there are records of received calls, missed calls and dialed calls in the phone book, alarm clock settings and self-made ringtones.
5) Check whether the production date of the nose is consistent with the warranty.
After reading the above items, you will know the authenticity of your mobile phone!
