How to test whether an apple is genuine?

1. Click Open Settings on Apple's mobile phone desktop. 2. Click to enter the routine. 3. Click to open [About this machine]. 4. Then, we can see [model] and [serial number] on the next page. We can check it by querying Apple official website. 1. Open Apple official website:/,and click the technical support option in the upper right corner of the page. 2. Select the device to query. For example, to query iPhone, select iPhone. 3. On the Technical Support page of iPhone, select Contact Support. 4. Click the page to view your warranty period. 5. Enter your serial number in the inquiry page, and click Continue (serial number acquisition: open phone settings-General-About this machine-serial number). 6. If there is no problem with the serial number of your device, the detailed information of the device will be displayed. Here is a special note: some friends will use red characters to prompt after entering the serial number: the serial number is invalid or not registered, so if there is no error in entering the serial number, it must be a problem with the equipment! Probably a refurbished machine or a patchwork machine.
