It has to be said that Apple mobile phones occupy most of the market. We are still the biggest sales channel of Apple mobile phones in China. Many people think that Apple mobile phones are easy to use, and there will be no card after long-term use. The performance of mobile phones is still very good. However, in the second-hand mobile phone market, many netizens say that they buy fake mobile phones, which is more worrying. So how can Apple second-hand mobile phones be identified Don't be true or false? If you want to buy a second-hand mobile phone, you must pay attention to it.
1. Click Set touch ID and password to see if there is an ID, and then test the fingerprint. The fingerprint must be tested before the detection is completed. Then test the WiFi function. After entering the WiFi interface, if the number of WiFi searched is changing all the time, sometimes many and sometimes few, it means there is a problem with the WiFi function. Finally, enter the ringing interface, press the volume + key and - key several times, and the mute key is also moved up and down several times. If there is no problem, you can enter the next step of detection.
2. Open the SMS interface and select the bright spot and gray mark under the pure white background. At this time, if there is hair and dust on the screen, you can see clearly. This belongs to the problem of backlight, not the quality of the machine, and will not affect the use of the mobile phone. Or in the SMS interface, after watching the white interface, pull down the status bar at the top, and then look at the gray interface. You can see abnormal dotted lines in this interface. If you don't see anything with special color in this interface, then continue to the next step.
3. Turn on the compass to see if it rotates normally. If there is no problem, slide left to the white interface and test again. *** Usually, if the external screen of the mobile phone is broken and you want to change the external screen, you will also look at the black interface. If no other color is displayed on the black interface, this detection is basically OK, and you can go to the next step.
4. Look at the voice memo, record a note by yourself, then listen to it in the receiver mode, and then listen to it in the amplifying mode again. If there is no noise in the receiver, then there is no noise in the amplifying mode. By the way, put your hand on the front camera to test whether the sensitivity is normal. If your hand covers the screen and goes out, it means no problem. Then you can go to the next step.
5. Go back to the main interface and drag an application at will. Drag along the Z-shape in the top-down order, and then drag along the edge of the screen. If pulley is applied in the middle, test the position of pulley and then continue. After the test, if the application icon automatically returns to the original position, the test passes and you can enter the next step. This step is mainly to test the sensitivity of the screen touch. Do not drag too fast. Focus on the edge and corner areas. If the model is more than 6S, then test whether there is a problem with the 3dtouch function.
6. The last step is to test the camera, the front and rear cameras, and the flash. If the display is normal, it means no problem. If according to the above steps after testing, there is no display problem, it can be judged that it is a real machine.
In addition, many people have proposed to check the serial number and serial number (IMEI) of Apple's mobile phone. In fact, these two numbers are equivalent to the ID card of each iPhone. You can find out the activation time and warranty time of the iPhone. It doesn't make much sense after the security time. You don't need to study the two serial numbers too deeply. When you get the mobile phone, you just need to check whether it matches the machine information in your hand. I hope you can learn this skill well, so that you will never be afraid of being cheated again!
