I want to buy a parallel Nokia C6 01 How can I be sure that it is not a refurbished machine?

I summarize the experience of others and my own experience to identify the refurbished machine: 1. Screw twisting traces, generally speaking, the refurbished machine will also pay attention to this problem, but there are a certain number of refurbished machines have this situation. 2. Whether there are traces of wear and tear at the charging contact point can only be used to judge whether it must be a refurbished machine, not a refurbished machine.

3. Whether the IMEI code of the label behind the machine is the same as the built-in IMEI code of the machine, most refurbished machines are the same. There are a certain number of refurbished machines whose labels are blurry and feel like mimeographs, and the fonts of new machines are generally angular and angular. 3. Whether there are blackening marks on the metal solidified on the shell of the body, such as whether there are oxidation marks in the metal that may appear in the battery compartment, if the new metal is silvery, it should be bright, and if it is copper, it should not be bright or stained.

4. Whether there are scratches on the shell, because some scratches cannot be covered under the spray paint, so pay attention to observation, and remember to check whether the accessories are brand new and no scratches! 5. Take a closer look at the quality of the shell jet, because most of them are re-painted, which cannot be carried out under vacuum conditions, and it is inevitable that there will be tiny dust particles falling on the mobile phone during the jet process. In addition, use a small amount of saliva to rub the printed text a few times to see if there are any traces of falling off, and the new machine will definitely not have traces of falling off.

6. Look at the places that are difficult to renovate, this depends on the situation of different mobile phones, generally such as keyboard contacts, to see if there is wear and tear, whether there are defects in the painting. Another thing is to see if there is a feeling of two layers of paint in the area where it is difficult to spray paint.

The most obvious part is to observe where the phone touches the battery, and the refurbished machine will know at a glance! There is also a place that is also obvious, that is, the inner corner screws of the mobile phone, the refurbished machine must have been disassembled, so there must be different wear and tear from the screws! This is also a more intuitive method.

Let's do it this way:

1. Look carefully for any marks on the screen; Whether there is dust in the data cable, headphone jack, speaker hole, lanyard hole, etc.

2. Carefully look at the battery lock on the fuselage to see if there are scratches, and whether there are spin marks on the spindles of the upper and lower covers.

3. Carefully check whether there are any records in the WAP and voice functions and call log information functions.

4. Smell the smell, the new machine has a special sandalwood smell, which will not dissipate in the short term after purchase, this smell is different from the general detergent and perfume smell, and also different from the smell of plastic or chemicals (ps: carefully check the fuselage to see if there is sticky wax and oil, the nails are slightly scratched, and if there is one, it is beautified by the merchant).

5. Carefully check the SIM card contact points and the contact points of the fuselage battery to see if there are any wear marks and the brightness of the new machine.

6. Check whether the gap between the seams of the shell is uniform and small, whether there are pry marks, and whether there are pick marks at the two sealing points under the screen in the upper cover.

7. The keys of the new machine are very flexible, the physical key feedback is strong, and the left volume button is only slightly loose or not loose.

8. Carefully check whether the fixed gong nails of the fuselage have spin marks, friction marks, paint and ink (you can use a magnifying glass), and whether the trademark has pry marks and scratches.

9. See if there are scratches on the film, the new machine is a one-piece laminating film, and there will be absolutely no bubbles in the original film, although the film technology of JS may be very high, but this point must also be checked.

10. The overall appearance is coordinated, and the shell is bright without any scratches.

Congratulations, you are indeed buying a licensed black C6. I don't know what your sound quality is not very good compared to, and the sound quality is not good due to many factors, audio source, audio, ** decoding chip. But in my experience, I think it's due to the bad original Nokia headphones, I'm also using Nokia's little dance now, at first I used the original headphones to listen really badly, and then I changed an iron triangle to a lot better, you can try to change a good stopper to try.

The first floor brother explained too long, let me explain briefly:

Asia & Pacific Area, the full name of "Asia and Pacific Rim", mainly includes some countries in Oceania, Australia, New Zealand, etc., some countries in East Asia, China, Japan, South Korea, etc., North America, South America, and some countries along the Pacific coast, such as the United States. This kind of machine is a real parallel commodity for us in China.

Hong Kong bank, Hong Kong licensed, sales in Hong Kong can also be guaranteed in the mainland, the key is to buy Zhenggang.

Personally, I think of course it is good for Hong Kong, which is cheaper than mainland licensed goods, and enjoys the same warranty system. Parallel goods are generally just merchant store insurance.
