How to tell if Nokia phones are refurbished?

Operate * # 06 # on the mobile phone. Will send a serial number, then check the serial number on your phone box, and then look at the warranty card. The serial number is correct, and it is normal with the warranty card.

1, shell The shell of the new machine is tightly attached, and the gap is smooth and smooth without burr. Refurbishers generally use imitation original shell, with uneven gaps and burrs. The upper and lower parts of the mobile phone shell are easy to be closed loosely, leaving a large gap. When recognizing, you can try to insert a small nail into the gap between the upper and lower covers of the mobile phone. If it can be plugged in, it is a refurbished machine. The surface of the shell is frosted like a new machine, and the mobile phone with small particles is absolutely not to be purchased. The paint on the machine shell was sprayed by JS. After a long time, the paint will fall off (the dust particles on the shell are caused by the operation without vacuum environment when painting);

2. The shell of the new machine has a faint sandalwood smell. If it is a refurbished machine, JS generally needs to beautify the fuselage. Although the appearance is smooth, it is not dry enough. When the cover is opened or the battery is taken out, it will smell of rubber, plastic or chemicals.

3. Keyboard and data cable interface. Due to the long-term plugging and unplugging of the charger plug and data cable, there will be black scratches on the charging interface of the refurbished machine that are difficult to eliminate. Keyboard refurbished machines mostly use the keyboard on the old machine or imitate the keyboard. The commonality of this keyboard is that it feels soft and has no toughness of the new keyboard;

4. Charging test. It is best to charge for a long time, generally 10 minutes or more. Because there are many refurbished machines that will run out of power after a long charging time. This is also a very effective method to judge the refurbished machine;

5.SIM card chip contact and battery contact. Generally, these two contacts JS cannot be replaced. If it is a refurbished machine, there will be obvious friction marks on the contacts of the SIM card chip, which looks shiny, which is caused by too much friction. If it is an unused chip of a new machine, the contact surface should be frosted;

6. Fix the screws. Mainly depends on whether there are obvious scratches at the interface between the screw and the blade, and whether there are pick marks on the two rubber pads below the inner screen.

7. Call quality. Bring your own SIM card to test the machine, call a friend, preferably a fixed phone, and ask the other party how the call quality is, whether the call sound is clear, whether there is noise, current sound and volume drop suddenly;

8. price. Because the spare parts of refurbished machines are mostly early products with poor quality, the price is also low. If you encounter a mobile phone that is ridiculously low in price but is called parallel imports by merchants, you can basically conclude that it is a refurbished machine.
