Although second-hand mobile phones are cheap, what should I pay attention to when buying them?

First of all, we must recognize the category of second-hand mobile phones. Maybe many people don't understand. Isn't the second-hand mobile phone used by others? It is true that second-hand mobile phones are used by others, but in the market, not all second-hand mobile phones are used by others, which is also the reason why the second-hand mobile phone market is deep. At present, there are mainly five kinds of second-hand mobile phones in the second-hand mobile phone market, which are quasi-new machines, official turnover machines, refurbished machines, assembly machines and second-hand mobile phones. So what's the difference between these five kinds?

Among these five kinds, what Bian Xiao can tell you is that the quality of the quasi-new machine is the highest, which is generally the profit of the mobile phone evaluation agency. That is to say, some small evaluation agencies buy their own mobile phones, open the packaging, activate the mobile phones, and make an evaluation. Basically, it is not necessary to put them in the second-hand mall. The official turnover machine is a machine officially recycled and refurbished by mobile phone manufacturers. The advantage is that you still enjoy the official warranty. Refurbishers are mobile phones refurbished by some mobile phone shops, and the quality is not guaranteed. Assembly machine is that some mobile phone shops recycle different parts and reassemble them into a mobile phone, and there is no quality guarantee. The second mobile phone is sold after personal use.

Among these types, half of the prices of official turnovers and quasi-new machines are close to the prices of new machines. If you have a chance to see your favorite second-hand mobile phone in real life, you must do these jobs well. The first is to test the basic functions of the mobile phone. What are the basic functions? That is, phone calls, text messages, cell phone signals and WiFi functions are all normal. The second is to look at the wear and tear of the mobile phone case, which is what we often call 99 new and 9 new. The third is to observe the screen carefully to see if there is light leakage, white spots, panda screen and even brightness.

If there is no problem above, the next step is to check the core hardware and camera. The core hardware can be checked by running software, such as Master Lu and Ann Bunny. The camera needs to be turned on by itself to distinguish. If all these tests are completed and the price is within your acceptable range, congratulations, you probably missed it. On the contrary, if one of these steps goes wrong, don't buy it no matter how cheap it is. This is what Bian Xiao summed up for you to pay attention to when buying second-hand mobile phones. If you think it is helpful, forward the collection and tell your family not to be fooled!
