  1. My Galaxy S7 Edge is displaying the “moisture detected in USB port” message, however it’s been two days and it still has yet to go away. I have followed all of the advised steps, including sealing it in a container full of rice. I’ve also tried other USB cables. However, the source of whatever is causing the message to appear has yet to be fixed. I’m down to 45% battery without a wireless charger. In short, my phone is bleeding to death. Any advice short of taking it to a specialist?

  2. My s7 edge has never been exposed to water and is giving me the moisture detection message. Wont charge or do anything. Tried the cloth, the hairdryer, and rebooting. Nothing is working. This feature is a major fail from samsung. Definitely will be switching to a different android soon.

    • agreed! I hate my s7 edge , it was cute and fun when I preordered it but its proven to be the most complicated device Samsung has. I have never experienced this may malfunctions with other devices. my phone has also never been exposed to water (even though the best feature is its water proof capability )

    • Turning off your phone doesnt always charge when the phone is getting this error message. Mine is getting this problem intermittantly even though it hasnt been exlosed to water at all. This is wacky! I wish there was a way to disable this function as clearly its malfunctioning since theres no moisture whatsoever! :(

  3. I find it stupid saying its waterproof etc but its not if you getting error message and after you even try dry out the port still same error and no charging that clearly is a issue with the design of the Samsung port that they need to either cover the port or redesign the port to stop with this issue

    I got a new a5 and now today 5days having it moisture error 2017 model and not been in water so for after using compressed air can blowing and rebooting phone and put the usb in at same time its charging but soon as you unplug and charge again it fails so I be taking it back and replacing with a different phone so annoying
