Samsung S22Ultra judging whether to refurbish the machine

As the last generation flagship model of the Samsung S series, the Samsung S22Ultra still belongs to a very competitive mobile phone at the same price in terms of performance and appearance, but this is the model released last year, which is why the probability of a refurbished phone is much higher than that of a new one. So how do you judge whether you have bought a refurbished phone on the Samsung S22Ultra?

Samsung S22Ultra determines whether to refurbish the machine tutorial

1、 Enclosure

The shell of the new machine is tightly jointed, and the gap is flat and smooth. Refurbishment machines generally use imitation original shells, with uneven seams and burrs. The upper and lower parts of the mobile phone shell are prone to loose closure and large gaps. During identification, try to insert the fingernail into the seam of the upper and lower covers of the mobile phone. If it can be inserted, it is a refurbishment machine. For mobile phones with small particles, the surface of the shell is sanded like a new machine. The paint on the shell of this machine is sprayed by JS, and the paint will fall off after a long time (small dust particles on the shell are caused by the operation without vacuum environment during painting).

2、 Odor

There is a faint smell of sandalwood when the cover of the new machine is opened. If it is a refurbished machine, JS generally needs to have a beauty treatment on the body. Although the appearance is smooth, it is not dry enough. There is a smell of rubber, plastic, or chemical after the cover is opened or the battery is removed.

3、 Call quality

Carry your own SIM card test machine, call your friend, preferably a landline phone, and ask the other party about the quality of the call, whether the call sound is clear, whether there is noise, current sound, and whether the volume has dropped suddenly.

4、 Check attached accessories

Whether the headset, power supply and battery are rough, and whether there is noise when listening to music. The battery charging time should be longer, generally more than 10 minutes, because many refurbishing machines will lose power if the charging time is longer, which is also a very effective way to judge refurbishing machines. Although many battery identification tutorials have been published before, the author recommends a most direct way to identify the authenticity of batteries. Mobile phones such as Galaxy SIII with NFC access address book function can read information directly with the random bus card. If there is information prompt in the mobile phone, confirm that the battery is true, and basically confirm that the battery is false without any prompt.

The above is the specific content about whether the Samsung S22 Ultra is a refurbished machine. Most of the methods are relatively simple and do not take too long. It is applicable to most models of glory. Even the mobile phone Xiaobai can accurately judge.
