The time it takes for the moisture notification to disappear depends on the moisture level and the device's capability to detect and dispel the moisture. In most cases, the notification disappears within a few hours once the moisture has evaporated or dissipated. However, if the device's sensors are malfunctioning or the moisture level is too high, it may take longer for the notification to go away. Therefore, it is recommended to keep the device in a dry and well-ventilated area and avoid exposing it to water or high humidity to minimize the chances of moisture-related issues. Additionally, if the notification persists even after drying the device thoroughly, it may indicate a hardware problem that requires expert assistance.
