S24 Ultra overheating

[Adi0]

How is this possible? I haven't had this issue one a Samsung phone since S6. I'm using YouTube in picture-in-picture,  posting some videos on Instagram and TikTok. There's air conditioner working in the room.

Maybe an app you've installed recently? Not fully compatible with multi window. Try it in Safe mode and monitor for a couple of hours.

Multi window has a Labs option, too, to force apps not necessarily designed for multi window. Forcing the app may cause overheating.

Which region do you reside in @Adi0 

I think I remember your not in the UK/ Eu. 

Even though you have air conditioning turned On the phone could still be affected.

I think he is in the EU.

I am in EU. We got Snapdragon Gen 3 here too for the S24 Ultra only.
