Xiaobai must know these three test tools when buying a second-hand iPhone.
The first is Aisi Assistant, which is also the most commonly used tool for everyone. You need to download Aisi Assistant software on your computer first, and then connect the mobile phone to be inspected with a data cable to get a complete machine verification report. Including the sales type of mobile phone, the place of sales, whether the hard drive, battery, camera and other information are replaced.
However, as a third-party detection software, ISIS Assistant is not 100% reliable, and merchants may also use special means to modify the ISIS Assistant's machine inspection results.
The second type is an hourglass tester similar to Aisi Assistant. It is also the same as connecting the mobile phone to the computer and verify the machine through the software. If the verification score is 100, it means that there is no problem with the mobile phone. But it also has the same problem as Aisi Assistant.
The third type is gsx machine verification. You need to use the mobile phone's serial number to query the original information of the device. You can also query the sales type, sales place, memory capacity, whether there is a network lock, activation lock, etc. Although you cannot check whether the accessories are original, it is relatively convenient to check. You can do gsx for the merchant before purchasing, or ask the merchant to provide the serial number. Secondly, as long as the serial number is true, the result of gsx detection is the most authentic and reliable.
