Are refurbished and used phones a concept?

There is a difference between a refurbished machine and a used phone concept.

Refurbished machine refers to cleaning some first-hand mobile phones with chemical liquids, repackaging the shell, replacing them with new chargers, batteries, etc., and packaging them as new machines for sale.

Second-hand mobile phones refer to mobile phones or redundant mobile phones that others do not use when they are updated, that is, old mobile phones that have been used by others. Phones usually have some functional problems or are in old condition and are not completely broken.

1. Refurbished mobile phone refers to the use of a second-hand mobile phone for a shell to pretend to be a new machine, the quality is very poor, that is, to collect the original movement, shell or outer packaging for maintenance or processing, and then sell it as a new machine. There are many types of them, the main ones are old machines with defective circuit boards, which are repackaged and sold as second-hand mobile phones after repair or parts assembly, and the performance of such machines is the most unstable;

2. The shell of the normal old machine is sold as a new one after treatment or replacement;

3. Machines from informal channels are sold as new ones after software refresh and repackaging, and the stability of this kind of mobile phone software is poor.

4. Second-hand mobile phones may have a little stain on the appearance or screen scratches, etc., and the depreciation machine is generally due to the personal reasons of the previous user or because of the quality of the machine itself to the second-hand market. The second type is the refurbished machine, the machine is generally acquired by the second-hand dealer, after the refurbishment treatment, and then put into the second-hand market, and even a part of the JS will directly put this type of machine into the new machine market, the appearance is generally relatively new, but the proportion of refurbished machine problems in the second-hand phone is very high.

1. The serial number cannot be found at all, which belongs to a completely different category, because any maintenance and sales records that are not official to Apple cannot be recorded in the database corresponding to the serial number. If it is a normal second-hand phone, the serial number should be able to know the activation time and warranty date, the vast majority of ipad2 has been warranted, and if an ipad2 has been refurbished, as long as the motherboard has not been replaced, it shows just an old machine that is out of warranty (or even may not be out of warranty but you can't get a warranty), which you can't find at all.

2. Even if you want to check it yourself, it is very difficult. Upstairs, a rookie said to check whether the screws have been screwed, I want to say, have you ever disassembled the ipad and mini? Do you think the iPad is so easy to disassemble?

First of all, you have to use a heat gun or hair dryer to blow the 3m super glue of the frame softly, and then you can open the front cover to operate, and this first step alone is not something that most ordinary users can handle. And in case this machine has really not been dismantled, you come out like this, and tear off the Bluetooth antenna inside (this is often glued to the front panel, and it is easy to damage it by inexperienced people), so who do you cry to?

3, so the inspection is very important, no matter what channel bought the machine, must agree on a certain inspection time, preferably more than one day, so that you can fully test whether its screen is intact (whether the inner screen has bright spots or bad pixels, whether the outer screen is sensitive to touch, etc., you can test by dragging the icon on the desktop, in addition, you can use the fruit ninja to test multi-touch, this is the most important, many second-hand ipads are broken on the outer screen and then find someone to replace it, and then **, the screen is usually OEM, The quality is uneven, so be sure to test it clearly), whether the Bluetooth can be paired correctly, whether the wifi speed and signal strength are normal, whether the microphone and the front and rear cameras are used normally, whether there is abnormal heating, and whether the battery life meets the requirements.

The activation time is the warranty start time, so it is normal for an inactive machine** to be a few hundred dollars higher, and usually an unactivated machine is absolutely insured.

To be honest, the identification is difficult, the value of the second-hand mobile phone itself is not enough, if you add some witness costs, there will be a lot of rip-offs. So I suggest that either you don't care if it's refurbished or not, or you go and buy a new one.

The difference between Apple's official flip and the new one:

First, the packaging method is different.

1. New machine: The packaging is not disassembled, and the complete package is sent together. The manufacturer of the original sealing machine will have a very regular arrangement of venting holes during the packaging process.

2. Official flip machine.

The packaging and the machine are sent in batches, the machine arrives first and then arrives, and then packs. In the process of transportation, it is easy to get the machine and replace the accessories halfway.

Second, the quality of the letter is different.

1. The new machine key eggplant: the manufacturer is a sealed package from the factory, and the quality of the mobile phone is better whether it is accessories or the main parts of the mobile phone.

2. Official flip machine: Accessories such as chargers, headphones, etc. may be worn or defective. There may be refurbished machines in the back sealing machine, and there are quality problems.

3. The warranty is different.

1. New machine: According to the regulations, the warranty time of the mobile phone is one year, and the repair time is not counted. The warranty period of the battery is half a year.

2. Official flip machine: the warranty period is less than one year, usually about half a year.

1. The packaging is different.

There is no mobile phone pattern on the box of the official flip phone, the white box, and the words "Apple Certified Pre Owned" are printed on the box. The official replacement machine is the same as the original machine box.

2. The definitions are different.

The official refurbished products are mainly second-hand refurbished products certified by Apple, and they will be strictly tested by the original Apple factory before being sold. Also enjoy all after-sales service. The official replacement is because after the iPhone has a problem, it is sent back to Apple's original factory for repair, which is specially used for after-sales replacement, and you can also enjoy Apple's after-sales service.

3. The serial number is different.

The phone's serial number records the details of your iPhone, as well as the activation status. The serial number can be queried to the activation time, purchase time, sales place, etc. of the iPhone. The beginning of n is the official change of machine. The beginning of f is generally an official flip machine.

Buy a mobile phone online In order to avoid buying a refurbished machine, you can choose the official website or go to the offline *** to buy, no matter which way you choose, you must choose a formal platform and channel. Nowadays, there are more and more second-hand mobile phones on the market, and many consumers will sell their old mobile phones to manufacturers to reduce their purchase pressure when buying new mobile phones, and these old mobile phones sold will be reassembled by many manufacturers as new mobile phones and sold. Therefore, when buying a mobile phone, we must distinguish between a new phone and a refurbished phone.

1. Buy on a regular platform.

With the development of the Internet era, there are more and more platforms for selling mobile phones, and when buying mobile phones, we must choose formal platforms and channels. If you are not at ease with some platforms, you can go directly to the official website or official *** of a brand of mobile phone to buy. The most practical way is to go to the offline store to buy and inspect the machine, and then make a choice.

2. Learn to distinguish between new and refurbished machines.

When buying a mobile phone, the first thing to pay attention to is the case of the mobile phone, the new mobile phoneEnclosureare relatively smooth, and the upper and lower parts of the refurbished machine will not be tightly closed. The second thing to pay attention to is thatData cable interfaceThe new machine will not have any scratches because it is not opened, while the refurbished machine will have scratches on the charging port because of frequent use and cannot be cleaned. The last thing to focus on is the phone's**Under normal circumstances, the gap between the new machine and the official price reduction is not very large, but because of the quality of the refurbished machine, the difference in the price of the mobile phone will have a big gap.

3. Go to the official website to check the activation time.

Many people are more excited to open and activate the mobile phone after getting the mobile phone, at this time we must confirm whether their mobile phone has been activated before that, and you can choose to check the activation time on the official website. If the time displayed on the official website is exactly the time when you activate the phone, then this phone is **, if not, it is likely to be a refurbished phone.

Refurbishing a mobile phone is actually collecting the original movement, case or outer packaging for repair or processing, and then selling it as a new machine. There are many types of them, the main ones are: 1. The old machine with defective circuit boards, repackaged after repair or parts assembly**, the performance of such machines is the most unstable; 2. The shell of the normal old machine is sold as a new one after treatment or replacement; 3. Machines from informal channels are sold as new ones after being refreshed and repackaged by software, and the stability of the general software of such machines is lacking.

The discrimination method is as follows: in the standby state of the mobile phone, the person 06 is lost, and a string of numbers displayed by the mobile phone is the serial number of its motherboard, which is written down; Remove the battery of the machine, and look at the serial number on the white label in the two labels behind the fuselage, which is the serial number of the case, and the other label is generally the network access permit. whether it is consistent with the previous figures; Look at the IMEI number on the packaging box of the machine, compare the three, and see if they are all consistent.

The packaging and instructions of the X0D X0A regular new machine are beautifully printed, mostly coated paper printing, the font and image are very clear and hierarchical, while the counterfeit packaging box is mostly a simple single-sided paper imitation, the font and image are very rough, the printing handwriting is blurred, and many informal channels of modified manuals are even copied. There are also some refurbished machines, although the original packaging box and manual, but after all, the machine is old, its packaging box must be worn, and the manual must also have traces of use.
