Notifications on and off :presence of dirt or liquid on usb port

Hi all,

On my FP6 I get regular notifications that the usb port is disabled because there is dirt or that it is wet. I assure you I keep my phone safe. After some time, it tells me that port is fine and it is activated again. To be sure I did vaccum the port and cleaned it with a small paintbrush. The notification still appeared after. Did anyone get the same issue ? Any idea on what to do to fix this. I am afraid it might refuse to charge when I need it.

Thanks

Hi, small update no more notification today. May be that is the kind of stuff that annoys users but resolve by itself.
