Suddenly, this morning (in fact a very cold morning) this message showed up in my xperia 5. In any case, I did not poor any water on the device and the device seems to charge normally.
Same thing started happening on my Xperia 5 II today too. It's not got wet or exposed to moisture, it stays in a case and in my pocket when I'm out. No firmware updates recently either, so really not sure why this is happening. Restarting the phone doesn't solve it.
@adyburns try the force restart instead of the normal restart. Also clear the phone's cached data first (settings - storage - clear cache & data - press OK)
