"shaking and blowing" or "send in for service"? You call that a solution?
This is a bug and people are reporting it coming back AFTER repairs. I've only had this stupid phone 3 months and it's doing this. I am really regretting buying a samsung product.
Update: I read in another forum that a couple of people reported this issue after leaving the b EA ach. I live at the beach. Recommendation was to rinse out charger port with distilled water and let dry. I did that. About an hour later the notification went away by itself.
Exact same issue happened this year with my Galaxy S8+, had it repaired and traded it with the Galaxy S9+, now happening again with it too. This is so frustrating 😤. My S8+ was only 8 months old and S9+ is just 6 months old. I don't know what's wrong with Samsung phones. Please help me if someone can find a solution to this issue.
I solved this problem by:
1. Clearing cache under Settings | Apps | Device Maintenance;
2. Clearing cache under Settings | Storage; and
3. Clearing all notifications on the notifications screen (including the moisture detected notification).
(4. A device restart might help on top of the steps above if they don't work alone.)
I don't know if all of these steps were necessary, or only one or two of them were.
I do know, like most people have reported, that even if my phone picked up any moisture around the charging (USB C) port, it was barely any, and it was probably dry for hours (including after leaving the phone in front of a fan heater) while the moisture notification continued to appear and prevent charging.
Ergo, this is a software glitch.
Ergo, Samsung is obnoxious for failing to fix it, where numerous people have complained, including on previous models.
One more reason not to shop Samsung.
