iPhone 8 Plus Flash not working in cold
I am using an iPhone 8 Plus 64 Gb on iOS 11.2.1
There is an issue with the camera flash, it doesn't work in cold environment.
When I try to click pictures or shoot video outside the camera flash doesn't fire it just blinks in Photo mode and nothing happens in the Video Mode.
I understand that I live in a cold place however as per apple the operating temperature is 0° and 35° Celsius and
I am facing this problem with temperature of 3 to 5 degrees.
I have tried reseting the phone, restoring the software through itunes however the issue is still there.
The flash light works if I use it from control center, then I keep it on for sometime and the FLASH fires in camera app too BUT after keeping the phone idle for sometime the flash doesn't fire again.
Is this a design fault? The hardware is not supporting the cold?
