Question:

Why does the camera on my Galaxy S20 FE display an "Exit Camera" pop-up mentioning "battery temperature too high" and not function properly?

Answer:

This issue occurs when your device has experienced an increase in battery consumption due to intensive usage or prolonged use of features or applications. As a result, your phone may temporarily heat up. Additionally, external environmental factors such as prolonged usage in hot areas, storing the device in extreme temperatures (hot or cold), or exposing it to direct sunlight can contribute to overheating.

When your device overheats, its features and performance may become limited, or it may power off to cool down. To reduce the temperature, the screen brightness and performance speed will be restricted, and battery charging will cease. Background apps will close, allowing only emergency calls until the device cools down. Consequently, the camera may shut down during use due to the elevated temperature.

This behavior is a standard safety feature designed to protect your device from potential damage. Wait for your device to cool down before attempting to use the camera again.
