Moisture detected in charging port consistently appearing

[cave_felem]

Hi, I have had my 23 ultra for about 4 months. Consistently I am getting moisture detecting in the charging port for absolutely no reason at all. I've tried all the steps on here, multiples cables. It usually lasts for a few hours and then starts working again, however I am starting to get this issue multiple times a week. The phone consistently has not been near water/liquid

Did you clean charging port? There might be fluff accumulated there. I used a straw to blow it clean. If it persists though contact Samsung tech support

Additional fluff works as soaken sponge - takes ages to dry

I had s21 ultra since 2021 and it happened a year after I got, and recently, I had no contact with a y moisture, tried everything that samsung Web told me too, but still nothing, but after 24 hrs it dissapears and acts like nothing happened, I already had the charging port replaced the 1st time
