iPhone 8. Problem with flash of camera

“Very low end”??? What are you saying??

The recommended operating range is from 0 to 35 degrees. My flash stops working at 10-22 degrees (Celsius). I believe this limit is far away from the low end of operating range!! This is unacceptable!

And it’s also unacceptable that Apple doesen’t answer to all the people complaining for this problem!!

Your flash isn't working

Use Control Center to test the LED flash. Turn the flashlight off and on. If the LED flash doesn't work as a flashlight, contact Apple Support.

If the flash isn’t working, or it goes off every time you take a photo, check your flash settings. Tap in the upper left of the screen to choose a different setting.

If you take extended video with the flash on, or you’re using the device in a very warm environment, you might see a message that says the flash is disabled. The message remains until your device cools down.

I have the same problem. Outside, with cold temperatures (+10/12 Celsius), the flash of the camera doesn’t work. Even if you force it. I tried all the procedures you’ve suggested and the led light works properly. Only when I try to take a picture, the flash doesn’t work. I also tried the DFU procedure. No way. Same problem. Please solve it!! 949€!!!! And I cannot take picture outside!!!!

This a user to user forum and you will never get an official response from Apple. They merely host the forum. If you want to be heard by Apple, then submit your thoughts to apple.com/feedback or contact Apple support. You can call my comments useless if you like, the fact of the matter is that the operating range is just that, an estimate.

That's at the very low end of the acceptable operating temperature. You may want to minimize your use at that temperature.
