The flash of Apple's mobile phone camera has been turned off. What happened?

Open the camera application of the mobile phone, find the "flash" button in the upper left corner of the camera interface, click and turn on the flash, and then take a photo with the camera at will to see if the flash can work normally. If the flash can work normally, there is nothing wrong with the flash hardware of the mobile phone.

2, set the flashing prompt

If you want a flashing reminder when you receive a message, you can open the settings, click the "General" option, click the "Auxiliary Functions", and then turn on the "LED flashing reminder" function. After turning on the phone, lock the screen of the phone, let others send messages or make phone calls, and see if the flash of the phone will flash.

3. Hardware damage

If the flash does not work with the above method, it may be caused by hardware failure, and the mobile phone needs to be sent to Apple's after-sales service point for maintenance.

Precautions for buying a mobile phone:

1. If you buy offline, you can unpack the machine in front of the clerk and solve the problem immediately. Online shopping, don't unpack the phone before you get it. You can check whether the seal is damaged first, especially if the iPhone 13 is replaced by an environmental seal, which can effectively avoid being unpacked by others in advance.

2. Check the attachment. Don't be busy turning on your mobile phone, and pay attention to check whether the accessories in the box are complete. IPhone 13 continues Apple's environmental protection concept since last year, without a charger. Attached with a data cable, you need to buy your own charger.

3. Check the fuselage. Check whether there is dust on the data interface of the mobile phone, carefully check whether there are obvious plugging and unplugging marks, whether there are scratches on the body and whether there are scratches on the screen. If there are any, contact customer service immediately for after-sales service.
