How to check a new phone

Everyone uses new phones right away, assuming there won't be any issues with them. Can wait for you to identify the issue; the 7-day package return/15-day package replacement period has long since gone and only the ability to send for disassembly and repair is left. Therefore, new owner and new machine: haste to complete the next six checks.

 

Aesthetics

 

It is best to inspect the phone in a well-lit area to ensure that the box is intact and there are no cracks or scratches in the paint. The phone will then check to see if the IMEI code matches the box by dialing *#06# in the dialing key. Additionally, the iPhone's card slot will display the IMEI code. If it is not consistent with the box, it is most likely a refurbished machine.

 

Screen

 

Look for issues with the phone's screen, such as poor spots, bright spots, dark spots, light leaking through the screen, a green screen, and others. Use a background image with a solid color—pure white works best—to detect. Use WeChat's shaking feature to find it with another phone in the dark if the screen is green like it is with the Huawei Mate20 Pro. It is advised that you concentrate on testing because there is a higher likelihood that the screen will have issues.

 

Sound

 

Sound can play music outside or make phone calls to test the speaker and earpiece. Finally, connect the original headset and use it to make calls and listen to music to check for any issues. As a side note, try the center button.

 

Camera

 

Tests of cameras Only a few photographs can be taken with the front and back cameras. Take as few shots of the subject as you can, like of a white wall. This will enable you to check whether the photos you shot are clear or if the lens has a black spot, dust, or both.

 

Warning

 

Start by measuring the call signal and the network signal. Call to check if the call quality is stable; the call signal is quite straightforward. Despite network unreliability, it is possible to use traffic and WiFi to watch TV shows and play games, respectively. The frequency of the issue is likewise high in the signal.

 

Charging

 

Of course, charging is used to test the data line and charger; regular charging is OK. After the phone has been fully charged for the first time, you can test the charging time and battery life. It is advised to use the aftermarket testing if, in comparison to the online information test, the charging time is very long, the range is inadequate, or there is another issue.
