Cool your iPhone

If you get a message that says Flash is disabled The iPhone needs to cool down before you can use the Flash, which means the area around the Flash is really hot due to the iPhone’s temperature. If you are using the iPhone or keeping the iPhone in the hot climate outside, move it to a cooler area so that iPhone cools down, and then try checking whether you are still facing this issue.
