How to distinguish refurbished machines from original machines on Taobao?

It is easier to distinguish high imitation phones because the system will be different between high imitation and high imitation. If you usually know something about mobile phones, you can distinguish them from refurbished phones. There is a way. Press *#92702689 #Check the accumulated system call time. Even if the mobile phone call time is cleared, this will not change. Other methods (copied online) of refurbishing mobile phones are actually collecting the original movements, casings or outer packaging for repair or processing, and then selling them as new machines. There are many types, the main ones are:

1. Old machines with circuit board problems are repackaged and sold after repair or parts assembly. The performance of such machines is the most unstable;

2. Normally, the casing of an old machine is processed or replaced and sold as new;

3. Machines from informal channels are refreshed and repackaged through software and sold as new. Generally, the stability of the software of such machines is lacking.

These refurbished machines have a unique feature, that is, they cannot enjoy the same after-sales service as regular licensed products.

★The following is the experience of how to identify refurbished mobile phones. Let’s take a look.

★Look at the serial number (IMEI)

The mobile phone serial number is like the ID card of the mobile phone. The IMEI number of each machine is unique. Generally speaking, it can be judged from this Whether a machine is genuine.

The identification method is as follows: Enter *#06# in the standby state of the phone. The string of numbers displayed on the phone is its motherboard serial number. Write it down;

Remove it For the battery of the machine, look at the serial number on the white label among the two labels on the back of the fuselage, which is the chassis serial number. The other label is usually the network access license.

Is it consistent with the previous number? Look at the IMEI number on the machine packaging box and compare the three to see if they are consistent.

If the motherboard serial number and the chassis serial number are inconsistent, then the machine is likely to have been repaired or assembled with parts, and you must not buy it. < /p>

The motherboard serial number can be rewritten using a computer and software. Fake serial number labels and network access licenses can be purchased for just a few dollars. To be cautious, you should continue to verify according to the following method.

★Look at the outer packaging and instructions of the machine

The packaging and instructions of regular new machines are beautifully printed, mostly on coated paper. The fonts and images are very clear and layered, while the fake ones are Most of the packaging boxes are imitations of simple single-sided paper.

The fonts and images are very rough, and the printed handwriting is blurred. Many modified instructions from informal channels are even copied. There are also some refurbished machines that use the original genuine packaging boxes and instructions.

But after all, the machines are old, the packaging boxes must be worn, and the instructions must also have signs of use. Please add more when purchasing. Pay attention and you will find it.

★Look at the network access license

There is a watermark on the real network access license, and the color on the surface is uneven, dark and light, thick and thin; while the fake ones are mostly copied , there is no change in surface color.

If you can’t see it, you can also use a banknote detector to take a picture of the network access permit. If there is an anti-counterfeiting pattern inside, it will show a red “CMII” pattern. The fake pattern is blurry.

Real network access licenses are usually printed with dot matrix printers, and the numbers are clear. If you look carefully, there are dents made by the pins, while fake network access licenses are printed with ordinary printers, and the numbers are not very clear.

No dents. Generally speaking, it is difficult to fake network access licenses because the equipment required for counterfeiting is relatively high in cost. In addition, you can also check the authenticity of the network access license by searching online.

I won’t go into details here.

★Look at the mobile phone case

When you open a new phone, you will obviously notice that there are films on the "key parts" of the phone for key protection, such as the inner screen and the outer screen. , camera, etc., as long as these parts come into contact,

fingerprints will be left. When you see the fingerprint on your new phone, don’t listen to JS’s explanation.

In addition, dust and traces of use are also unavoidable in refurbished machines.

The gaps between the upper and lower shells of the machine, the gaps around the keyboard, and the charger slot are all places that can easily harbor dirt and evil practices. ” place, the hinge of the flip-top machine will also leave traces of use.

Special attention should also be paid to this.

★The casings used in refurbished machines are generally imitations of the original ones, or the old casings are carefully processed, so the front and rear parts of the machine casing are prone to not closing tightly and leaving large gaps.

The identification method is to use your fingernails to see if they can be inserted into the seam between the upper and lower covers of the mobile phone. If it can be inserted, the case is assembled. For machines that have not had their casing replaced,

JS sprayed it with a spray like detergent before selling it, and the surface of the old casing immediately had a matte effect like a new one. If you don’t look carefully, it will You will be fooled by JS,

But it won’t take long for the paint on the casing to come off. You must carefully observe the casing when purchasing, because no matter how good JS’s craftsmanship is, it will not be the original equipment. Advanced,

If you look carefully, you can see some small particles, which are dust, caused by not working in a vacuum room when painting.

★If it is a flip machine, you can also check the joint of the flip cover, because sometimes, no matter how well JS handles the surface of the machine, these places will inevitably leave some traces of dust.

Also check whether the screws on the fuselage are brand new and whether there are any signs of being turned by a screwdriver. What's more important to note is that many new mobile phones have a distinct smell of sandalwood.

Old phones and shell-replacers generally do not have such a smell, or there is an odor left during processing.

★Look at mobile phone accessories

New phones from regular manufacturers have a full set of original accessories, and they must at least have a battery and a charger. The accessories of refurbished mobile phones are generally not complete or not original.

Before purchasing a mobile phone, it is best to go to the relevant website to find out what the standard original accessories are, so as to prevent JS from deducting accessories. .

In addition, if you find scratches on the matching charger and headphone plug, then the phone is likely not brand new.

★Look at the usage records

Look at the games, text messages, phone book, call records, self-made ringtones and other items in the mobile phone to see if there are any usage records,

If so, it is highly suspected of being renovated. In addition, during normal use, the phone automatically shuts down or freezes frequently.

It can be said with certainty that there is a certain problem with the motherboard or software of this phone.

★Check the warranty

Ask the dealer about the warranty period of the machine and ask for a formal invoice. Refurbished mobile phones cannot enjoy all the rights and interests stipulated in the "Three Guarantees" of regular mobile phones.

Therefore, there is generally no warranty period or the warranty period is relatively short. If the seller says that they are responsible for the warranty, they cannot agree, because regular mobile phones are generally covered by a nationwide joint warranty.

If the seller cannot do this, then there must be something wrong with the phone.

★Look at the price

As the saying goes, those who are greedy for small gains will suffer big losses. Before buying a phone, it is best to check the price of the phone in the local newspaper or website. If the price quoted by JS is "very cheap", you should be wary of such a "cheap" phone. They are either refurbished mobile phones, products from informal channels, or accessories that are lacking in quality. It is recommended to buy mobile phones from regular sales stores with good reputation and high service.

Have complete three-guarantee certificates, valid delivery invoices and three-guarantee cards. , so that when there is a problem with the machine, the legitimate rights and interests can be guaranteed.

★Smell

Most new machines have a special aroma that occurs when electronic products leave the factory. This smell cannot be imitated by ordinary perfume. A similar fragrance can also be smelled on newly manufactured computer accessories. Refurbished machines generally don't have this smell. Even if JS has been scented, it will never smell like a new machine.
