How to tell the difference between a new phone and a refurbished phone

Enter "06" on the main interface of the mobile phone, and the mobile phone will automatically pop up the serial number of the mobile phone (if there is no serial number, it is a fake), check whether it is consistent with the serial number marked on the back of the mobile phone (remove the battery), if it is the same, it is genuine. As for parallel goods and licensed goods, there is actually no difference in quality.

I summarize the experience of others and my own experience to identify the method of refurbished machine:

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. Whether the IMEI code on the back of 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.

There are many ways! You have it, and the methods between brands are not the same!

How to distinguish between a new mobile phone and a refurbished mobile phone is as follows:

1. Carefully check the mobile phone equipment: check whether there are scratches and dust on the mobile phone screen, headphone hole, speaker hole, and data cable hole, and carefully see whether there are scratches at the battery lock of the fuselage, whether there are spin marks at the rotating shaft of the upper and lower covers, and whether there are indentations at the two bumps on the upper cover. Carefully inspect the SIM card contact points for wear marks on the body battery contact points.

Check whether the new phone is a refurbished phone, the most important thing is to check the details.

2. Check IMEI: Usually each mobile phone has a unique identification code, that is, IMEI, when the mobile phone is assembled, each mobile phone will be given a unique set of numbers in the world to identify. The number of the identification code contains the phone's:

Model (the first 6 digits) + production place (2 digits) + production sequence number (the last 6 digits) + inspection code (the last 1 digit).

3. Check mobile phone accessories: mobile phones have a full set of original accessories, while refurbished mobile phone accessories are generally incomplete or not original products; If you find scratches on the plugs of the companion charger and headphones, the phone is not new.

Problems with refurbished machines:

One of them is an old machine with a defective circuit board, which has been repaired or repackaged after parts assembly**, and the performance of this type of machine is the most unstable.

Second, the shell of the normal old machine is sold as a new one after treatment or replacement.

Third, the informal channel machine is refreshed and repackaged as a new one after the software is refreshed, and the stability of the general software of such machines is lacking. <>

1.Serial number query tool,Apple products must have a serial number,So,Generally for iPhone, it's a setting-general-about the serial number in the machine.,The string of 11-digit alphanumeric codes displayed in the serial number position of the machine。 You can enter the serial number in the professional Apple serial number query tool for inquiry.

2.If it is a normal refurbished machine when it is sold as a new machine, the warranty time, purchase place and other information queried here will definitely help you identify the service life of the machine, whether it is a national bank and Hong Kong bank, etc.

How can I tell if my phone is refurbished?

Due to the existence of copycat machines, parallel imports, cloning machines, refurbished machines, etc., the IMEI number of mobile phones can be changed by means of flashing and other means, so it is impossible to accurately identify the authenticity of mobile phones and whether they are licensed goods by serial number, software detection, IMEI number, and mobile phone origin.

If you want to identify whether the mobile phone is the best licensed, please bring the purchase invoice, repair card and machine, to the nearest service center, the consulting service center personnel machine within the scope of the warranty if there is a performance failure can be repaired, if the machine can be repaired, if the machine can be repaired, it is the first licensed machine. This is the best and most accurate method.

As people become more aware of these machines online, fewer and fewer people are being scammed. There is still no shortage of refurbished and assembled machines for sale. In the Android market, this situation is rare, and it generally appears on the iPhone, and today I will also talk about how to distinguish whether the iPhone is a refurbished machine or not.
