Apple 1 1 Mobile inspection of new aircraft:
1, preparation before purchase
After buying a new machine, I suggest you register an Apple ID in Apple official website as soon as possible. Click here to create an Apple ID. I believe that friends who have used Apple mobile phones know the importance of this Apple ID. To register with their own email, be sure to remember the login password and the answers to security questions. If you are afraid of forgetting, it is recommended to back up and record this information after registration.
Get the SIM card ready. Of course, it is an activated SIM card, which can be used normally.
2. Check in in time after purchase
Appearance of fuselage: after unpacking, be sure to check whether there are any paint drops, black spots, scratches, black spots and other anomalies, especially scratches.
Display screen: Check whether there are bright spots, light leakage and green lines on the screen after starting.
Parts sound: press the power button gently with your fingers and shake it in your ear at the same time to see if there is any sound echo of loose parts.
Camera flash: check whether the front and rear lenses are normal and whether the flash can flash; Turn on the flashlight and see if it works properly.
Physical buttons: check whether the buttons on the side of the fuselage can be used normally.
Screen Touch: Check whether the screen touch is available normally, and open the control center to check whether the function is normal.
Call test: Insert the prepared SIM card and call a person to check whether the call function is normal.
Speaker: Turn on the video or play music to see if the speaker hole is playing normally.
Touch ID or Face ID: Enter fingerprint or face information through device settings to detect whether it can be unlocked for normal use.
Accessories: Check whether the charging accessories can be used normally, and can be directly connected to the equipment for charging.
3. Further check.
Check whether the equipment is brand new:
After the iPhonexr phone is activated, we can go to Apple official website and check the warranty date through the serial number (System Settings-General-About the phone); If "serial number is invalid" is not found or prompted, then the device is not completely refreshed or all data is erased. Check whether there is a hidden id lock.
