S9+ screen goes black when the phone gets cold

[Sigurthor8]

So I cant even sleep with my window open, because the phone gets cold and then it goes black. And then the alarm clock docent work. I have sent the phone to get repair. They said the upgraded the hardware, done testes and everything work fined. But still it has the same issue. Any one here having he same issues?

How cold is cold? In northern Finland or northern Norway these nights, that's probably too cold for the phone. Anything lower than 32°F (0°C) is likely to shut the phone down. Not just the screen (although that's affected) but the battery too.
