How to tell if the Nokia phone you just bought is a refurbished phone?

Refurbished phone: It is a second-hand mobile phone with a new case and packaging. Parallel imported phones can be refurbished as new. Some parallel imported phones are refurbished and sold as licensed products. Some licensed products that have passed the warranty and do not want the warranty are refurbished and sold as parallel imports. There are also some that are refurbished or refurbished. Mainly sold as new machines. Nowadays, those doing renovations are more professional. Generally, the original shell and original accessories are used, but due to the packaging, original goods are not available. Therefore, most of them are assembled, the workmanship is relatively rough, and the paper instructions are not as exquisite as the original ones. Refurbished phones are mainly supplied to the new phone market. Selling refurbished phones second-hand will only result in a loss, so they will not be sold as second-hand phones. Therefore, players who buy new phones should pay more attention, mainly not to be greedy for small gains. Because there is a big price difference between refurbished phones and brand-new phones, it is easy to attract players who want to buy new phones cheaply.

Refurbishing a mobile phone is actually collecting the original movement, casing or outer packaging for repair or processing, and then selling it as a new machine. 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 a new one;

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 serial number of a mobile phone is like the ID card of a 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 the battery from the phone and look at the white one of the two labels on the back of the phone. The serial number on the label is the chassis serial number, and the other label is usually the network access license. Is it consistent with the previous number? Look at the IMEI number on the box of the machine 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 from parts, and you must not buy it. If the three serial numbers are consistent, and there is a network access license, it can basically prove that the machine is genuine, but it cannot be 100% sure, because the current JS can fake anything, and the motherboard serial number can be obtained using a computer and software. Flashing, fake serial number labels and network access licenses can be bought for 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, with rough fonts and images, and blurred printing. Many modified instructions from informal channels are even copied. There are also some refurbished machines that use the original packaging box and manual. However, since the machine is old, the packaging box must have wear and tear, and the manual must also have signs of use. Pay more attention when purchasing and you will be able to find out.

★ 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 license. Is there really an anti-counterfeiting pattern inside? It will show a red "CMII" pattern. The fake pattern is blurry. Genuine 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 and there are 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, which will not be explained in detail 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 where dirt can easily hide. There will also be traces of use on the rotating shaft, so you should also pay special attention to it.

★ 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 casings replaced, JS sprayed them with a detergent-like spray before selling them, and the surface of the old casing immediately had a matte effect like a new one. If you don’t look carefully, you will be fooled by JS. < /p>

But it won’t take long for the spray 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 is not as advanced as the original equipment. If you look carefully, it will 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, there will inevitably be some traces of dust left in these places. 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, while old phones and shell-replacement machines generally don't have such a smell, or there is an odor left behind 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, it is best to go to relevant websites 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 probably not brand new.

★ Check the usage records

Look at the games, text messages, phone book, call logs, 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 can't do this, there must be something wrong with the phone.

★ Look at the price

As the saying goes, those who take advantage of small things 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. Such "cheap" phone is not a refurbished phone or an informal channel. Products are accessories that are “fine and short”. It is recommended to buy mobile phones from regular sales stores with good reputation and high service, and have complete three-guarantee certificates, valid delivery invoices and three-guarantee cards. In this way, when there is a problem with the machine, the legal rights and interests can be guaranteed.

★ Smell

Most new machines have a special aroma that comes from electronic products when they 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, and even if JS has been scented, it's definitely not the smell of a new machine.

7. Recharging a new phone: Recharging a new phone mainly means that the phone has been used for a short period of time and cannot be seen as used. Some licensed products still have a warranty. The host and accessories are all original, licensed and parallel imports are available, and the price is relatively cheap.

I really don’t know whether it’s a good thing or a bad thing to sell such a machine. It’s best not to know it to yourself, so that your psychology will be more balanced.

8. Board machine: Board machine is called assembly machine and assembly machine. Mainly based on assembly, because usually the motherboard is purchased from a small factory and assembled with parts, and then assembled into a finished machine. That’s why it’s called a board machine. There are big quality problems with board machines. Because during the production process, parts that are not functional or sound are generally not installed into the machine. (For example: 8310 only has a bottom frequency of 900Hz and no high frequency of 1800Hz. 7610, 6610, 6100, etc. are not equipped with infrared rays.) Generally, board machines are only produced for machines with good sales volume because they can be driven. (Such as: 8210, 8250, 8310, 7210, 7250, 6610, 6100, T618, T628...) These are the most common models. Similarly, motherboards are only supplied to second-hand sellers. Players who buy new machines do not need to worry about buying a motherboard.
