Hello, We understand how frustrating it is when the phone is overheating.
Whether you're using a phone, tablet, smartwatch, or earbuds, all Galaxy devices have a set temperature range, where they operate at their best. While they may feel warm under certain conditions, like charging, this does not affect the device's lifespan or performance. However, if your devices get too warm, it could cause some issues.

Next, check to see if a third-party application may be responsible for this behavior. You can check with Safe mode: https://www.samsung.com/us/support/answer/ANS00062983/ If the device does not overheat in Safe mode, uninstall third-party applications until normal device operation is restored.
If the troubleshooting is not helpful, the phone will need to be evaluated by a certified technician.
