What is the reason for the camera's black screen, flashing light and slow response after the iPhone 7 plus is broken?

At present, the known solution to this problem is to leave it to Apple for after-sales maintenance. Speculation may be a hardware problem. Apple has not yet responded to this matter, nor has it launched a related maintenance plan. It is suggested that users with problems can take the initiative to contact Apple for solutions.

Hello! The cable of the camera is loose. Take off the phone and press the cable of the camera back. Please be careful not to break the screen if you want to take it down. If you find someone else to repair it, it depends on the price you negotiated with that person, almost tens of dollars! The mobile phone LED indicator is abnormal, so users are advised to:

1. operation: set-display -LED indicator-charge/low battery/notification/voice recording, and select the box as required.

2. If the LED indicator lights up automatically all the time, it is recommended that the standby interface slide down the top curtain of the screen to check whether there are missed notices or missed calls in the notification bar.

3. If the LED indicator is still not normal, it is recommended to try to back up data (contacts, text messages, pictures, etc.). ) and restore the factory settings (Settings-Reset/Privacy/Personal-Restore Factory Settings).

4. Check whether the phone has the latest firmware version, and if so, try to update the firmware. Operation: Settings-(General)-About Equipment-System Update.

If it is invalid, the user will bring the purchase invoice, maintenance card and machine to the mobile phone for after-sales service, and the professional after-sales engineer will help with the inspection.
