What should I do if my iPhone shows a white screen when I buy it from Meituan?

1. Press the HOME button twice, then clean up the background programs, and then restart. If the white screen on your phone is not resolved, just press and hold the power button and home button at the same time and wait for it to turn on.

2. If the above two methods do not solve the problem, you can download iTunes on the computer, and then connect the phone to it with a data cable to flash the phone. Remember to make sure that it does not flash during the flashing process. There is a power outage or network outage, otherwise the phone may become bricked.

3. The root cause of the white screen on the mobile phone is the aging of the mobile phone battery. Therefore, if the white screen often appears, you can replace the battery, or contact the manufacturer for related repairs.
