Galaxy Watch4 overheating

dig through and see if there are any other connections/things turned on that are not actually connected..i know in the past usually if a device was heating up it was due to it searching for a connection over and over until it could find one..this constant searching would heat up devices..not fully sure this is what you have going on there but cant hurt to check..you might also jump over to Samsung forums. usually you can find others running into like issues and at times ways to fix it or work arounds until its fixed by Samsung if this is whats going on.
