Hi, i wash with simple water the phone, because dirty.
After awhile display shows headset connected, but it's not. I tried to plug the headset and unplug, but i seen water on the plug. Tried to dry the hole but same problem . After some hours problem fixed alone... I tried again today and the same result. Headset permanently connected but not.

after each contact to water be sure the ports for usb+jack are free of water. blow inside and dry it else the jack status is wrong or inserting usb plug could harm the device!
