Samsung has released a video to help users with moisture detection warnings on Galaxy smartphones, which indicate liquid in the USB charging port. The video suggests practical steps such as unplugging the charger, cleaning the port and connector, and allowing the device to dry. Additionally, it recommends clearing the cache of the USBSettings app, suggesting that the moisture detection system may be malfunctioning rather than indicating a hardware issue. The steps to clear the cache include accessing Settings, selecting Apps, showing system apps, searching for USBSettings, and clearing the cache. Samsung does not guarantee this will fix moisture issues and advises seeking professional help if the problem persists. Users may consider wireless charging as a temporary solution while addressing any moisture concerns.
