Hi,
it depends how long the phone has been in the water, here is a post were a FP2 survived a “toilet dip”:
I would suggest to disassemble all parts a put them in a box with rice or even better silica.
It seems to me that the phone has been switched on a bit too early. On a vacation my old Nokia phone got totally wet due heavy rain. After several days of drying in a rice bag it worked again.
Good luck!
EDIT: rice is very dusty, so Silica is definitly the better choice!
Further to my earlier comments about the rice - I’m looking for a good explanation about why rice isn’t a good idea. So far I’ve mainly found studies commissioned by phone repair companies. so this comes some disclaimers about source impartiality.
There’s results from one study:
From a different study (has some flaws, though!), using sponges to determine how effective desiccants are:
Finally a BSc project:
What I took away from reading these and other sources is:
The real difficulty is what happens when the moisture is salty (sea water, soup, …), as then you’ll need to remove the traces of salt - which is sometimes done by rinsing in water - which obviously can introduce more moisture damage! As always: if unsure, contact a repair professional as soon as possible.
I guess silica could be actually more effective, but in emergency cases it’s easier to find rice in your household or a nearby supermarket, so you gain precious minutes to save your phone from corrosion.
But if air is more effective in every cases, then disassembling as fast as possible and putting the phone on a paper towel is the best way to rescue your phone.
I did drown the FP2 too (half of it but obviously enough). Drying (silicon, many days in tupper and so fourth) did not help. Just does not switch on. Any news here? Only solution asking FP to get substitute motherboard (if they have any at all yet)? Any good ideas?
@cgjanna managed to revive the FP2 by disassambling it and cleaning it with contact cleaner spray:
Thank you, it eas a good try, however it did not work, unfortunately. No reaction even after quite a few days of waiting. Corrodate parts seem clean now, however. I just can’t see which part is really affected, so I don’t know what to try next. Thanks for the help anyway. Any more hints would be highly appreciated. BTW interesting experience trying to learn to live without mobile again, as old substitute is dying, too. Could be Fairphone 3: not having any

So, I dropped my fairphone into a catfish tank at the aquarium (small child involved!). It was fished out within about 30 seconds, had switched itself off, I took it apart, dried out the pieces, and put it into a box of rice for 48 hours when I got home. It looks dry now and I have charged it but the phone is completely dead. What next?
Rice is a bad idea. Take it apart again and get a gas duster to clean the rice particles off of all the modules. Then just let it dry some more days just laying around.
Once you done that report back and we’ll find out which modules are destroyed and which ones still work.
I have only realised you could seperate the inner module from the screen…which I have just done. Inside there is lots of white sediment, do you think this is salt from the aquarium water? Should I clean it off?
You should really sepparate the individual modules to let them dry and clan any salt or rice off of them.
By best guess would be, that that’s rice, but could be salt
Yes, take it apart - https://de.ifixit.com/Teardown/Fairphone+2+Teardown/52523
Hi folks,
with the help of a dried fruit automat, it may take only one day and the phone is dry again. This item works with a max. temprature 55-60°C. Not too much for the Phone. DO NOT TRY TO DRY THE Li-Ion-Akku with this machine. 
Greetings

To my knowledge it is not only for drying any electronic device. BUT the cleaning from the remaining conductive particles. It is not the “fluid” itself causing the damage, but the “conductivity” if its ingredients.
Therefore rinsing is prior to the following drying step.
Anything “cleaner” than usual fresh water would do. If nothing cleaner is available destilled water would do a better job than fresh water (as it is generally clean enough for being used in conventional lead batteries), medical alcohol (70% +) from the pharmacy even works best.
Rinsing the mainboard at least twice and drying it properly at an moderate temperatur of less than 50°C may recover the mainboard if it did not experience any short circuit within the first minutes taking an unvoluntary bath. Using silica may support the drying process. Actually time is the vital point here.
Having a try inserting the battery or furthermore powering up the device within short time due to impatience may simply bring further damage setting the final state to any electronic device, which mostly is irreparable damage (finally a candiate for the repair service which maybe could have been avoided).
There is also a good step-by-step guide how to do at “http://praxistipps.chip.de/anleitung-smartphone-mit-wasserschaden-reparieren_27179” (unfortunately in German language).
Having only conventional options will expect users to have at least 1-2 days of patience for the first test.
Hey there,
maybe here’s hope for all the sad people that dropped their phone in water, like me one year ago.
Directly after the accident nothing worked to dry the phone. I seperated all the parts, put them in rice, on the heater, tried to remove the white spots… After about 2 weeks I had given up my nearly brand new phone and “buried” it in his shipping pack.
Circa one month later I coincidentally picked it up again - and it is working perfectly since this day till now! All the data ist still there, even the screen is (except one little spot) not damaged.
So don’t loose hope and stay patient!
Good luck, Anna
If the phone was dead when taken out of the water, there is unfortunately also a good chance you had a short circuit (particularly if it was salt water) or some part broke already.
Anyhow, good luck, maybe it will still work later, as some posters experienced.
On case you have access to a second phone you could also try to replace the different modules one after the other to see if only one module broke.
I also had a water-related incident recently… My water bottle leaked in my bag on the way to a dance class. Unfortunately the bag held the water really well so the phone was probably sat in an inch of water for maybe 5-10 minutes 
When I got it out the screen was off, but the torch was on, and I was unable to turn the phone/torch off, only by removing the battery. I took the back off the phone and battery out immediately and dried as best I could, then put in rice when I got home (wish I’d seen this first, although I only have one tiny sachet of silica at home!). I left it in the rice for a couple of days, and when I tried again the torch was still stuck on and the phone wouldn’t start up. The red dots on the back panel had bled so I guess the connections are messed up… Recently the side of the case, where the volume button is had warped and split, so I water got in quite easily. Really wish I hadn’t put off replacing the back case now!
There are a lot of useful things in this thread, so thank you to all who have contributed! There are definitely things to try before I give up, or send for repair. However I have never taken the phone apart fully before, so not sure how to do it. Is there a video anywhere that someone could share the link for? I have looked but unsuccessfully so far.
Thank you
Hey @Selkie_Emily I just wrote a guide for situations like this in the hope that more people will read the relevant information in time.
You can find it if you click on #waterwiki. Please check out the “Check for damage” paragraph.
Oh and for taking the phone apart check out our #disassemble guide.
