Hello butterscotch_s,
Welcome to Apple Support Communities!
If we understand your post correctly, you're receiving a message on your iPad that the flash has been disabled and the iPad needs to cool down before you can use the flash. We'd like to help!
Below is an article for help with the camera on your iPad.
If the camera or flash on your iPhone, iPad or iPod touch aren't working
Also, have a look at the article below to see what may happen when your iPad gets too warm or cold.
If your iPhone, iPad, or iPod touch gets too hot or too cold
Specifically, this section in the article:
iOS and iPadOS devices have built-in protections to prevent overheating. If the interior temperature of the device exceeds the normal operating range, the device will protect its internal components by attempting to regulate its temperature. Here are some of the higher ambient-temperature conditions and activities to avoid, because they might cause the device to change performance and behavior:
- Avoid leaving the device in a car on a hot day
- Avoid leaving the device in direct sunlight for an extended period of time
- Avoid using certain features in hot conditions or direct sunlight for an extended period of time, such as GPS tracking or navigation in a car, playing a graphics-intensive game, or using augmented-reality apps
If the interior temperature of your device exceeds the normal operating range, you might notice these changes:
- Charging, including wireless charging, slows or stops.
- The display dims or goes black.
- Cellular radios enter a low-power state. The signal might weaken during this time.
- The camera flash is temporarily disabled.
- Performance slows with graphics-intensive or augmented-reality apps or features.
Additionally, if you're navigating, the device might show this alert and turn off the display: "Temperature: iPhone needs to cool down." Navigation still provides audible turn-by-turn directions. When approaching a turn, the display will illuminate to guide you through the turn."
Let us know if you have any questions.
Thank you for using Apple Support Communities.
Take care!
