Wow are your temps still that low? How about when wireless charging? I have the South Korean version too and I hit about 40c when wireless charging, and a lot of times it just sits around 35c when doing normal tasks.
See the test temps below. It does heat up a bit when charging- let me test how hot next time i do.
It gets warm - but rarely and at rather odd times. Like yesterday, when the only apps i was using were MS edge and music.
It runs pretty cool when under the msot stressful tasks i guve like when i edit videos usuing inshot or when i run multiple apps on dex. It stands out especially because my old note 10+ got quite hot under both these scenarios.
I don't really game.
