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.

Wäre möglich, da es auch nicht mehr aufgetreten ist. Ich kann es aber auch nicht 100% bestätigen, dass wäre reine Spekulation. Du solltest immer ein original Ladekabel verwenden was nirgendwo defekt ist.

I had the same problem... That means there are problems with the charging cable (or the USB port). Try a different adapter and/or charging cable (official from Samsung). If it still doesn't work, then it must be the USB port. It has to be firmly connected. If you pull on it gently, it shouldn't come loose. If it still comes loose, then the cable is definitely damaged.
