Look at the serial number

The serial number of a mobile phone is just like the ID card of a mobile phone, and each mobile phone has a unique IMEI number. Generally speaking, it can be used to judge whether a mobile phone is genuine or not.

Look at this shell

The shell used for refurbished machines is generally original, or the old shell has been carefully processed. Therefore, the front and rear parts of the machine casing are easy to close loosely, leaving a large gap. The identification method is to carefully observe whether there are traces of warping or opening at the joint of the front and rear shells. Observe whether the two screws under the fuselage are touched by a screwdriver.

For machine with no shell replacement, that merchants spray them with wat mist similar to detergent before selling, and the surface of the old shell immediately appears a frosting effect similar to that of the new machine.

When buying, you must carefully observe the case, because the technology of the merchant is no matter how good, and the original equipment is not advanced. If you examine it carefully, you can see uneven painting and color cast.

Look at the usage records

Look at the price

As the saying goes, greed is cheap, and big losses. Before buying a mobile phone, it is best to know the price of the mobile phone on the website. If the price of js newspaper is "very cheap", be on your guard. Such "cheap" mobile phones are either refurbished mobile phones, informal channel products or accessories. It is recommended to buy a mobile phone in a regular store with good reputation and heavy service.

There is no software, only a website, and there is a UC browser in the mobile phone to directly let the fruit powder check what battery cycle, main frequency and screws are only superficial, so you can probably see if they are new. Don't blame me for copying the third point above, it's all my own. Actually, I'm afraid of buying a high imitation iphone. The easiest thing is to go to qq to see if the iphone is online. If it is a small mobile phone on the internet, it is definitely a high imitation ~

Good luck ~
