s9 heat walking

[Android Central Question]

Hello. My s9 is getting hot when i am walking. I tried with flight mode(with bt, wifi off), maximum battery saver, deleting s-health, factory reset, android oreo and android pie.
None of the above solved my problem.
It is completely normal when i am travelling with my car, or sitting at table or while using it.
Is there anyone who experienced same situation, or anyone who can suggest somethings.
Exynos model
Thank you very much.

Sounds like a rogue app

it sounds like a fitness app maybe trying to count steps or record distance while you are walking.
