• Flashlight Caution: Avoid direct skin contact with the camera flash while it is on. Swipe down the Quick Settings panel > Disable Flashlight immediately after use to avoid targeted heat exposure.

When heat is detected during battery charging

• Disconnect immediately: Unplug the charger, close all running apps, and allow the device to cool completely before resuming charging.


• Inspect the hardware: Check the cable and multipurpose jack. If the cable is frayed or damaged, replace it with a genuine Samsung accessory.


• Clear wireless pads: Ensure no foreign objects (metal, magnets, credit cards) are placed between the device and the wireless charger.

When heat is detected during regular device usage

• Update your software: Keep your device updated to the latest software version to ensure optimal thermal management firmware.


• Restart your device: Restart your device to clear temporary software conflicts between running apps.


• Turn off unused connectivity features: Swipe down the Quick Settings panel and toggle off features that drain battery and generate heat, such as Wi-Fi, Location (GPS), and Bluetooth, when not in use.

• Close background apps: Open Settings > Tap Device care to check for high battery consumption or background app activity, and close any unused apps.

• Clean up storage: Delete unnecessary files and uninstall unused apps to optimise storage performance.


• Reduce screen brightness: Lower the display brightness if it is set to its maximum level.


• Allow the device to cool down: If your device overheats severely, stop using it immediately and allow it to cool down.
