Some people worry about buying refurbished machines, so how do I verify whether the mobile phone is a renovation machine?
1, housing. The new machine housing is engaged with compact, and the gap is smooth and smooth, no burr. Refurbished machines generally use imitation original housings, gaps are not flat, there is burr, and the upper and lower parts of the mobile phone case are easy to close, there is a big gap. When I identify, you can use a small finger nail to try the seam of the cover of the phone. If you can insert it, it is a renovation machine. And the surface of the shell is asked as the new machine, and the mobile phone with small particles is more than 10,000. The lacquer of this machine housing is from JS, and the time is long, the paint will fall off (dust small particles on the casing, there is no vacuum environment during painting);
2, the new machine opens the cover, there is a touch of sandalwood. , Or chemical odor;
3, keyboard and data cable interface. Because the charger plug, the data line is long-term plugging, the refurbished machine charging interface will have difficulty black scratches. The keyboard renovation machine uses the keyboard on the old machine or the keyboard. The commonality of this keyboard is soft in touch, and there is no toughness of the new machine keyboard;
4, charging test. The time to charge is preferably longer, usually in 10 minutes. Because there are many renovation machines to power out. This is also a very effective way to judge the renewal;
5, SIM card chip contacts and battery contacts. These two contact JSs are generally could not be replaced. If it is a renovation machine, then the SIM card chip contact will definitely leave a clear friction mark, looks bright, which is excessive friction. If the new machine has not been used, the contact surface should be matte;
6, fixed screws. It is mainly seen that there is no obvious scratch in the screw and the knife interface interface, and the two rubber pads below the inner screen have no traces.
7, call quality. With SIM card, call to your friends, it is best to fix the phone, ask the other party's call quality, whether the call sound is clear, no noise, current sound, volume size, no decline;
8, the price. Since the renovation machine is mostly the early product, the quality is also poor, so the price is also low. If the price is low, the merchant is called the palette, it can basically be refurbished.
