Some people are worried about buying a new phone. How can we check whether the new phone is a new phone?

1. Shell. The new shell is compact, and the gap is smooth and smooth without glitches. The refurbished machine generally uses an imitation of the original shell, the gap is not smooth, there is a burr, the upper and lower two parts of the mobile phone shell is prone to closed is not tight, there is a large gap. During identification, you can use your finger nails to try to insert the seams on your mobile phone. If it can be inserted, it is a new machine. The shell surface is like a new machine, and there are small particles of the mobile phone, it is not to buy. The paint of this machine shell is sprayed by JS. After a long time, the paint will fall off (the dust and small particles on the shell are caused by no vacuum operation during painting );

2. There is a faint sandalwood smell in the cover of the new machine. If it is a new machine, JS generally needs to make a beauty on the body. Although the appearance is smooth, it is not dry enough. There is a rubber smell after it is opened or removed from the battery, smell of plastics or chemicals;

3. keyboard and data cable interfaces. Due to the long-term Plugging Of the charger plug and data cable, black scratches that are difficult to eliminate will occur on the refresh charging interface. On the keyboard refresh machine, the keyboard on the old machine is usually used, or the keyboard is modeled like the keyboard. This kind of keyboard features a soft feel, without the flexibility of the new keyboard;

4. Charge Test. It is recommended that the charging time be longer, generally more than 10 minutes. Because many refresh machines will be powered off after a short charging time. This is also a very effective way to judge the refurbished machine;

5. Contact between SIM card chip and battery. These two contact JS cannot be changed. If it is a refurbished machine, then the SIM card chip contacts will leave clear friction marks, looks shiny, this is caused by excessive friction. If it is a new unused chip, the contact surface should be frosted;

6. Fixed screws. It mainly depends on whether there are obvious scratches on the screw and knife interface, and whether there are any pick marks on the two pads under the Internal screen.

7. Call quality. Bring your own SIM card to test the machine and call your friends. It is best to make a fixed phone call. Ask the other party about the quality of the call, whether the call sound is clear, whether there is noise, current sound, or whether the volume suddenly drops;

8. Price. Because the spare parts of the refurbished machines are mostly early products with poor quality, the price is also low. If the price is too low, but the seller calls it a fake mobile phone, it can basically be determined as a new phone.
