Where is the designated after-sales service center of iPhone6S in Minhang District, Shanghai?

You can go to Room 803, Building 1, Lane 7866, Humin Road, Minhang District, Shanghai for professional testing, or try to call the 02 1 Apple 629 Customer Service 200 Service 98 hotline for consultation. I believe they can repair and replace the good solution and maintain the price.

Restart equipment

Press and hold the On/Off button until "Move the slider to close it" appears. Move the slider to turn off the device. After the device is turned off, press the On/Off button to turn it back on.

If you can't restart the device, press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds until the Apple logo appears to reset the device.

Clean the screen with a wet lint-free soft cloth.

Hope to adopt! !
