How to check if the Samsung 5830i is a refurbished phone?

1. Screw twisting traces, generally speaking, refurbished machines will also pay attention to this problem, but there are a certain number of refurbished machines in this regard.

2. Whether there are traces of wear and tear at the charging contact point can only be used to judge whether it must be a refurbished machine, not a refurbished machine.

3. Whether the IMEI code of the label behind the machine is the same as the built-in IMEI code of the machine, most refurbished machines are the same. There are a certain number of refurbished machines whose labels are blurry and feel like mimeographs, and the fonts of new machines are generally angular and angular.

3. Whether there are blackening marks on the metal solidified on the shell of the body, such as whether there are oxidation marks in the metal that may appear in the battery compartment, if the new metal is silvery, it should be bright, and if it is copper, it should not be bright or stained.

4. Whether there are scratches on the shell, because some scratches cannot be covered under the spray paint, so pay attention to observation, and remember to check whether the accessories are brand new and no scratches!

5. Take a closer look at the quality of the shell jet, because most of them are re-painted, which cannot be carried out under vacuum conditions, and it is inevitable that there will be tiny dust particles falling on the mobile phone during the jet process. In addition, use a small amount of saliva to rub the printed text a few times to see if there are any traces of falling off, and the new machine will definitely not have traces of falling off.

6. Look at the places that are difficult to renovate, this depends on the situation of different mobile phones, generally such as keyboard contacts, to see if there is wear and tear, whether there are defects in the painting. Another thing is to see if there is a feeling of two layers of paint in the area where it is difficult to spray paint.

You open the back cover and see if the screws have any traces of twisting, and take off the battery to see if there are any scratches on the inside.

Dial with mobile phone:* There will be an IMEI number displayed Compare the IMEI on the phone box to be the same, that is, otherwise it is not.

There should be no refurbishment in the regular store, only parallel goods and licensed goods.

You need to check this yourself:

Method 1: Turn on your phone and enter the dialing interface, enter *, and then the IMEI code will pop up automatically, and the displayed IMEI code should be the same as the IMEI code under your phone's battery.

Method 2: Go to the regular ** inquiry, preferably a foreign **, because now the fraud network usually has the following characteristics of refurbished opportunities: although it looks like new, but the chip inside will be damaged, there are many ways to identify the refurbished machine:

1.Find a professional to disassemble the phone for identification.

2.Double-check whether the accessories on your phone, such as the battery, are compatible with your phone. Because most of the accessories of the refurbished machine are non-original.

3.**Whether it is much lower than the market price.

I bought it in **, and tell me the name of the store. I have been selling mobile phones for 7 or 8 years, and I have to see if the three codes are consistent. If they are all consistent, there is also a network access license mark that is licensed. Give a high score.

See if the SIM card slot is new.

Check on Samsung's official website. If you have an activation date, you will find out.

The meaning of the three-in-one code refers to the IMEI code, and each machine has an IMEI code, which can be found in 3 places on the machine. If it's all the same, then a few liters of the refurbished machine will be very small!

The first strip appears on the box of the machine.

The second is that you can see it when you remove the battery.

The third one requires you to install the battery, and after turning on the computer, enter * on the keyboard and a string of numbers will come out, which is the IMEI code.

If these 3 are the same, congratulations! If you hit it all hands, please laugh and make a noise!

1. The biggest feature of the refurbished machine is that it generally appears on the old models, and the new models basically do not have refurbished machines, because there are no old machines as raw materials.

2. When purchasing, be sure to check whether there is a complete package, and all mobile phone packaging boxes have serial numbers, please confirm whether the serial code on the body is consistent with the packaging box before installing the battery. Then turn on your phone and type* to see if the two match. If there is any difference, it can be judged to be a refurbished machine.

3. Of course, the seller may not provide packaging on the grounds that it is a parallel import, so you can check the following aspects. However, if the boss does not provide the box, it can generally be directly identified as a refurbished machine.

4. Check all the jacks, generally not attach a protective layer to all the jacks. The easiest to identify is the headphone jack, which is generally empty all year round in mobile phones, and the caliber is large. It is very easy to enter the dust.

Just check for dust. Due to some limitations, it is not possible to completely remove the dust from the headphone jack during refurbishment.

5. Finally, you can observe the fit of the screw, because the refurbished machine is usually not the original shell, the tolerance will be relatively large and the seal is not good.
