Does anyone know what this symbol during charging means?

Occurred a while back on my Tab S9Fe and hasn't re-occurred since. I'm talking about the yellow triangle thing.

Dirty/wet charging point. Might be an issue with the charging point as well. Unplug the phone and try again in some hours.

This occurred a while back. I just now remembered I had taken a photo and wanted to ask. It was the first charge ever though. The tablet was new.

The yellow sign indicates a problem with the charger or connection. Try a different charger to see if that solves the problem.

Could be the cable, too.

The problem occured like a month ago and hasn't re-occured since. I was just wondering what it meant.

Dann sollte in der Mitte ein Ausrufezeichen stehen und kein Blitz.

It's the cabe from my samsung phone. The problem never occurred on my phone and hasn't re-occured in like a month. So maybe it was really just wet. But doesn't it just refuse to charge if it's wet? It charged normally, not sure if it took longer or anything though.

Das gelbe Warndreieck zeigt einen Ladefehler an. Entweder war das Kabel nicht in Ordnung oder es gab tatsächlich ein Problem mit dem Akku.

Und wenn das seitdem nicht mehr aufgetreten ist, war das aber was einmaliges?
Ich glaub ich hab die Einstellung während des Ladens auf Schnellladen gestellt (also das Kabel rausgezogen, nachdem es schon ne Weile lud, umgestellt, wieder reingesteckt). Kann's vielleicht daran gelegen haben?
