Any battery operated device that wasn't intended to get wet, remove power / pull the battery immediately. I've seen moisture temporarily short out a device - but once dried it's ok. But if power is not removed, the moisture (through electrolysis) acid etches, changes component values, and that does a majority of the destruction.
Do not be impatient - that is what sinks 80% of the possible survivals.
Open every door, bay and crevice on that thing, and let it DRY OUT. Multi-layer circuit boards, flexible PCBs, and dense electronic packaging in modern electronics allow moisture to reside in there with next to zero air movement. (which is what is needed to dry out)
Don't do the opposite - and try to hit this thing with a heat gun, or an oven, that can be equally bad.
My buddy got the great idea to pull zero atmosphere on his phone after it got wet... and yeah, all the moisture evaporated w/o any heat. His caps and LCD also asploded in the process.
So yeah, wait, wait, wait, and then pray before you power it back up.
