I recently updated my Galaxy Fold 6 to the latest patch version: F956UTUES2AXKF / F956UTOYM2AXKF / F956UTUES2AXKF. Since this update, I’ve been repeatedly receiving a "Check charger/USB port" notification indicating "moisture" or "foreign material."
However, I’ve thoroughly inspected the USB port, and there’s nothing inside. The phone is practically new and hasn’t been exposed to moisture or anything that could have damaged the port. Despite this, the alert keeps appearing and disappearing intermittently.
Before the update, I didn’t experience this issue.
@juanpedro86 If there is no debris or moisture in the port, this could indicate that the USB port has been damaged. This typically occurs when using a cheaply made or damaged USB cable. The damage can accumulate over time.
I would first try replacing your USB cable with a well made quality cable to see if the warning disappears. If it doesn't, you should contact Samsung Care+ about getting the device evaluated.
