Hardly, hehe, only a small number of machines can be seen in a simple and direct way, and most machines are directly invisible. I can tell you as an insider. If you want to learn something, you can hi me if you have time, there are some things that will offend some merchants if you talk about them here.

Now on the market, the general factory machine for more than 2 years, as long as it is new, 9% is refurbished, no need to look.

1. The refurbished machine generally adopts the imitation original shell, the gap is uneven, there are burrs, and the upper and lower parts of the mobile phone shell are prone to close tightly, leaving a large gap. In addition, from the aspect of feel, you can also roughly feel that the new machine is very comfortable in the hand, and the refurbished is not as good as the second-hand mobile phone with a better shell due to the use of imitation shell.

2. There is a faint sandalwood fragrance when the lid is opened for the new machine, if it is a refurbished machine, there is a rubber smell, plastic smell, or the smell of chemical agents after opening the lid or removing the battery.

3. Due to the long-term plugging and unplugging of the charger plug and data cable, the charging interface of the refurbished machine will be scratched. If you look closely, you can see that even the most professional person can hide the scratches that have been moved.

4. If there are conditions, you can carry out a charging test, many refurbished machines will lose power after a long charging time, and this situation will not occur in new and second-hand mobile phones with good motherboards.

5. Take a closer look at the SIM card chip contacts and battery contacts, these two contacts JS generally cannot be replaced. If it is a refurbished machine, then there will definitely be clear friction marks on the contacts of the SIM card chip, which will look shiny, which is caused by too much friction. If it is an unused chip for a new machine, the contact surface should be frosted.

6. Look at the fixing screws in the bright place, mainly to see if there are obvious scratches on the interface between the screws and the knife edge, and whether there are any picks on the two rubber pads under the inner screen.

7. Look at the earphones and expansion card slots for dust, whether they are worn, generally speaking, there are metal contacts inside, but it is not particularly easy to see directly from the outside.

8. Try the call quality, which is crucial no matter what kind of second-hand mobile phone you buy, and the call quality largely determines the value of the mobile phone.

The box summarizes the above points of identification methods for refurbished mobile phones, hoping to bring some help to friends who buy mobile phones, beware of buying refurbished machines.
