My FP3 has fallen in water for 30 seconds.
When it got out of water, i still worked; I imediatelety stoped it.
After 30 minutes, when I got home, I started dismantling it.
I separated the screen, then the top module,
and now I still see some water near the fingerprint sensor , between the plastic case and a metal plate 1 cm wide.
I guess I should remove the big metal L shaped piece protecting the motherboard, But I could not find any video or information in Internet on that …
That was before reading the water damage wiki :
so I didn’t remove the battery before 30 minutes, and I’m afraid damage is done !
