When recharging the battery did you receive the message “USB port moisture detected” on your Samsung smartphone? In this guide, we will see how to fix the error on Samsung Galaxy devices, so as to allow you to recharge the phone without any problem. If you have a Samsung device like a Galaxy S7/S8/S9, Note 8, Note 9 or Note 10, you must know that the manufacturer has classified these devices as water-resistant with IP68 certification which guarantees resistance to water sprays and dust as long as the device is not submerged to depths greater than 1.5 meters and that is not kept immersed for a period exceeding 30 minutes, furthermore certain behaviors could make the resistance to liquids less effective, such as the immersion of the device in salt water, ionized water or alcoholic beverages as they could inevitably lead to an entry of liquid fast.
The level of impermeability is questionable, there are people in fact who used the Samsung at the sea and after a few tens of centimeters of immersion, the phone started to show the first problems of malfunction caused by water. So be careful not to exceed the depth limits set by the manufacturer or the liquid in which the phone is immersed or you could find yourself with serious damage to the device, even if it is classified as water-resistant. Several people have had the opportunity to experience the immersion of the smartphone in water, others have kept the phone in a very humid place, finding themselves at the time of recharge with a message on the display of the Samsung phone with the writing USB port moisture detected and in this case any attempt to recharge the smartphone battery will be impossible. In this guide, we will see all the methods that can be used to bring the device back to its normal functioning.
The IP68 certification indicates that Samsung devices such as the Galaxy S7 / S8 / S9, Note 8, Note 9 or Note 10 can manage water pressure up to 1.5 meters deep and for a duration of 30 minutes, preventing damage both if accidentally wet or immersed in water. However, by immersing the smartphone in the water on its own, it could still cause damage to the phone, as the resistance of the device to the liquid may depend on many factors and if one of these fails the warranty in case of need, it may not be responsible for failure. We see below all the methods and tricks that you can try if you received the USB Port moisture detection message on a Samsung device when trying to recharge the battery.
