[Galaxy Note GT-N7000 General] dr. xp55:
I went to the beach today and put my phone in my shoes on some rocks near the water (yes I know, very stupid mistake) . A huge wave came and knocked my shoes along with the phone into the water. My phone was literwlly floating in the water for about 5 seconds. At that point I didn't care about anything else, and ran and scooped it out and ran to dry it with my shirt. I took out the battery, sim and sd card and left it for half an hour. Despite what just happened, it turned on, with still fully functioning touch, no water in the screen, just about everything works, except a major issue of the speakerphone and mic. But i tested it with headphone and hands free and it is working. Other than this issue, which IS a major issue, i am just amazed that it is still functioning 95% properly.

Does anyone know what I could do to fix the speakerphone and mic? Can I fix it myself by opening it up, or should I just send it to Samsung? Would they figure out its water damaged, and not fix it? Or would they fix it, but for a cost?
[Galaxy Note GT-N7000 General] anonymous572:
Try to put it in to the rice for 20-30 hours
[Galaxy Note GT-N7000 General] dr. xp55:
Yeah I know about this trick. But that's usually if the phone doesnt turn on, or its going haywire which is not the case for me. Would it fix the speakerphone and mic?
[Galaxy Note GT-N7000 General] drkalo:
I guess it's kinda late but I would suggest that you keep it off with battery, and sim and sd card out for much more than 30 minutes. Let's say overnight at a dry and warm environment.

Edit:

p. s. Your oven is not an option :)
[Galaxy Note GT-N7000 General] anonymous572:
It might help with many things. It helps me with mic and touch on my galaxy s two years ago. Screen was working and buttons too but touch did not respond and speaker was a half silent. After this rice procedure everything was fine.
[Galaxy Note GT-N7000 General] BUBA0071:
You can bay Spare parts

I have changed my usb print-port, and i thing you can get trubble with charger, going beeb, beeb. showing your phone is on charger when not. Spare parts are cheap on ebay. I would get

"OEM Charger Port Micro USB Connector Mic Flex Cable Samsung Galaxy Note N7000" and

"Samsung Galaxy Note jack conn. flex with speaker"

You can get both parts for 28 US $. And your Note will be good as new. the usb port contains new mic.

If you are handy the note is a frendly phone to service.

There should be Youtube videos out there by now.
[Galaxy Note GT-N7000 General] Master_User:
Last year in sommer i have a similar problemm with you. I have let my phone without batterie in my balconie in a shadow place for 2 days after that it works again. Outside temperatur was 30-40 C°. Give it i try if no one else have a better idee :)
[Galaxy Note GT-N7000 General] kawgirlval69:
myth..doesnt work... and for those who will disagree...please tell me how the rice cleans the corrosion that occurs when water hits the board when it is on..and i guarantee that happens.... all rice does is get dust in the ports... if it is not touching the liquid then it is not absorbing it any faster than it is already evaporating on its own... a fan will do 100 times better than rice... moving air=faster evaporation. then after its dry it needs to be cleaned and treated so the corrosion does not come back..

it needs to be cleaned and treated by a professional that knows what they are doing and has the right tools and chemicals...

smart advice

@dr. xp55 pm me and ill help you out getting this working again the proper way...
[Galaxy Note GT-N7000 General] dr. xp55:
Thanks guys, I'll try all these ways. Hopefully it will be in working order by the end of the weekend.

Thanks, I've sent you a PM :)
[Galaxy Note GT-N7000 General] Pika007:
The rice treatment is not a myth. When treated quick enough (same day, day after tops), the rice absorbs the moisture out of the device, and prevents corrosion from developing. Why does it work better than just leaving the device out in the open? the air around you has moisture, sticking it in rice creates a much dryer environment, so water dry up faster, and moisture get sucked out faster. A fan is moving air, but air with moisture in it. Unless you're in a desert. So, either rice or hair dryer on low heat setting and very carefully.

If it already has corrosion, nothing can really help.
[Galaxy Note GT-N7000 General] anonymous572:
This "myth" helps me to fix my Galaxy S after water.
[Galaxy Note GT-N7000 General] kawgirlval69:
is a MYTH and if you would like to argue im glad to in pm... as for the corrosion... if the phone was on when it got wet it has corrosion...100% guarantee so your whole point is moot... and again if the rice isnt touching the liquid it is not absorbing it hence it is evaporating at the same rate bottom line.... and since you want to try to debunk the fan...well the fan creates friction and the friction will promote faster evaporation whether the air has moisture or not... there is a difference between humidity and large areas of liquid... so again rice DOES NOT WORK... i work on these things for a living so i think i may know a thing or two about this...

im trying to help people save their phones so dont think im trying to stop diy... im just trying to show you a better way that actually works and is scientifically proven...

btw how long have you been working on phones??? just curious on your background... and please feel free to keep on using your rice.. even if your phone starts to work again... it wont be long till the corrosion catches up and your phone wont be working... your call because again i dont care what you do... im trying to help others that want help and good advice..not idiots that want to argue...

lastly if it has corrosion..i can make it work again.. i do it daily and make a nice living at it.. so i really dont think you should be giving advice on this since you say there is no hope if there is corrosion... sorry but it is what it is..

---------- Post added at 02:11 PM ---------- Previous post was at 02:09 PM ----------

im sure it did... and i hope it makes you feel better believing that it did.... taking the battery out and letting it dry on its own would have done the same thing... either it didnt get anything wet that was electrical or it is just a matter of time before the corrosion catches up...

again just trying to help and again if you want to argue pm me...
[Galaxy Note GT-N7000 General] Akiainavas:
The rice thing does work, although people misunderstand its purpose... It won't do a thing if your phone was damaged. It simply helps to take the water out of phone's chassis etc. - if it already touched the board and damaged the circuits, it won't do anything. Anyway, best to use silica-gel or at least salt crystals as they work ten times more effectively.
[Galaxy Note GT-N7000 General] kawgirlval69:
again it does not help... IF THE PHONE WAS ON WHEN IT GOT WET, IT GOT DAMAGED SOMEHOW..THERE WILL BE CORROSION SOMEWHERE... I GUARANTEE IT... if the rice is not touching the liquid then it is not absorbing it... unless you take the whole phone apart and i mean the heat shields and all and then immerse the phone in the rice it is not absorbing... and if you went to all of that trouble then rice is not necessary...

this is to all others who doubt my reasoning... please tell your # of years experience working on phones and your training....

again im not trying to argue im trying to help you save your phones when they get wet and for them to still be working a year or so later...

i prove it daily when customers bring in their phones to my shop in bags of rice that have been in there for weeks and still nothing... i do my method and they work... proof enough for me and my customers...

It does help
[Galaxy Note GT-N7000 General] Akiainavas:
Have you even read my post, or just the first sentence ? It doesn't matter if the phone was ON or OFF. If water got through the case and touched the board while the battery was in - it's most likely fried, and even a ton of rice won't help.

If water never touched the board and got only on the case, or between the case, then it might help - not fix the phone, simply absorb the water from the case, so it won't pour on the board.

Anyway, it doesn't matter. Don't put it in rice... putting it in rice is the method for people who don't want to take their phone apart - but know what ? If you wet your phone, your warranty is void anyway, believe me - service will know what happened. Just take your phone apart as soon as possible, let it dry, and pray that water didn't reach the internals...
[Galaxy Note GT-N7000 General] PoisonWolf:
You probably want to wash the device's internal with really strong alcohol....the salt in the sea water is not good for the device....
[Galaxy Note GT-N7000 General] sujal:
I just don't get why the hell are people arguing over this? I don't care if it's a myth or not, if it works for you then good, if not, go find some other way around. Putting each other down won't change anything, neither the facts nor the opinions. Relax guys!? :)
[Galaxy Note GT-N7000 General] apd:
Quite right. Kawgirlval - perhaps just saying it once and not being quite so aggressive might get people to listen more. There are ways and ways.....
[Galaxy Note GT-N7000 General] apd:
We all value the views of people who know more than us. Just no one likes being lectured. Keep it civil and I'm sure you have a huge amount of experience to offer us all.
[Galaxy Note GT-N7000 General] M3TALLICA:
Both the methods work ??

There was flood in our district. Water was knee high on the streets and I wanted to see how much force it had.

It was silly. I was dragged 20-30 meters with my galaxy ace in my pocket. As soon as I got out I removed battery, sim card and sd card. Rushed to home and blow hot air with hairdryer; then I put it in with rice.

And there was no problem, it worked the same as it was working earlier. (Until I put hot bowl of noodles on the screen).
[Galaxy Note GT-N7000 General] Note_E:
Rice is a great home remedy for wet, blocked ears but I wouldn't let it near my phone. Best thing you can do is remove battery, SD card, and leave it off for at the very least 24 hours. Before the age of smart phones, I used to put the phone in the oven at 150 degrees F but I definitely do not recommend that on today's phones.

Kawgirl is 110% right though, corrosive damage is done...and nothing rice can do about that.

To OP, sorry for your luck. There is a small chance the mic will begin working again after it completely dries.
[Galaxy Note GT-N7000 General] dr. xp55:
aright just a heads up, up till about an hour and a half ago, I've kept it off with the battery, sim, and sd card removed. Now I have managed to disassemble my phone (yea youtube is awesome :) ) I've un-hitched all the cables and removed all the pieces. So my phone is right now in about 8 different pieces (including stylus and back cover) I cleaned it with just tissues, cause there was sand and dust, and now air drying it. Should I clean it a different way? someone mentioned alcohol. Also at close inspection with a magnifying glass, I do see corrosion in the usb port. I'm gonna leave it like this for the next 24 hours.

Based on what kawgirl and some others have said about the corrosion, what am I looking at? Is it screwed?

I appreciate all the help and comments about what works and doesn't.

and kawgirl, desperate times calls for desperate measures. Initially I did put it in rice for a little while :p :rolleyes: (just the whole phone piece and battery). Maybe it did something, maybe it didn't. But now I'm trying your way ;)
[Galaxy Note GT-N7000 General] samic:
I can attest that rice method works. Rice can absorb a fair amount of moisture out of your phone, but I've seen people doing it wrong all the time... You're supposed to put crapload of rice with your phone in a ziplock bag. How much of rice? your phone should be burying with rice.

Straightly speaking you should use Silica Gel instead of rice, like this:

http://www.lifehacker.com.au/2012/03/save-silica-gel-to-rescue-a-wet-phone/

Also don't submerge your phone into Alcohol. Your phone may have components that was glued together (for example, mic and headphone) so don't do that. What you should do is took apart your phone and clean the metallic parts with q-tips and alcohol. Remember to use purest alcohol possible. No it wouldn't be perfect but hopefully it will make you phone last a bit longer.

One last thing, if you battery was dry it's okay. But if it's been wet before, even it seems to be working don't use that battery. Just buy another one. Corrotion in battery is no laughing matter.

To kawgirlval69,

Try to put your hand in a bucket of rice for 5 mins, then come back and tell me it's a myth. Be ready for some lotion action.
[Galaxy Note GT-N7000 General] RavenY2K3:
Just to give my experience when this happened to me...

I , ike you, was on a beach, walking just deep enough in water to cover my feet, my phone was in my pocket and I some how got water in it, perhaps off my hands when checking for messages.

It seemed to be fine for a couple of days until I noticed it would not charge, closer inspection revealed that the salt water is MEGA CORROSIVE and damaged the USB port, but luckily that part is like £10 or there about on Ebay. So if I were you I'd get looking for a replacement part and save it in your watch list ready. You have to make sure you get the right revision for your device, Rev 1.0 I think, as Rev 0.0 is for i9220.

I have a couple of this component spare, just in case such occurrences happen in the future, as I had similar problems with my S II, so paying the small sum to have spares is better for me, than my phone going away for repair for 2 weeks.
[Galaxy Note GT-N7000 General] bamboo12:
water is in a constant state of evaporation and condensation.. what the rice does is absorb the evaporated water vapor and reduces the condensation rate, a fan does the same thing by moving the water vapor away and also reducing the condensation rate and thus drying it

if it doesn't work.. why do food manufacturers put silica bags inside their packaging? maybe they have a bit more of an idea than you do, i mean you only fix mobile phones, what degree do you need for that? don't act like you know everything
[Galaxy Note GT-N7000 General] drachers:
The rice thing is placebo folks. The main thing that's going to get the water out of there is air and gravity. Rice is for eating and throwing at weddings.
[Galaxy Note GT-N7000 General] Tuffcheez:
I know this is old but.... Went into a steam room with my watch on, the watchface got filled with moisture. Buried watch in a bag of rice and ziplocked it. Following day all moisture was gone, and the watchface was clear.
[Galaxy Note GT-N7000 General] samic:
Nobody accuse you of lying, kawgirlval69. I (or we?) just don't agree your assertion that silica gel and rice are useless. You don't have to take it personally.

silica gel also used in gas mask canisters during WWI so it does absorb measurable amounts of moisture as well. I just pull a quick search on the interweb and take a quick look of normal commerically available silica gel spec and as it turns out it does quite a good job of absorbing moisture:

http://www.apsnyc.com/pdf/silica_gel_SW_2003.pdf

The OP said the phone "flow" on water so we all persume it wasn't totally submerge in the water and it might still worth a try to get the mic and phone working. I don't think anybody raised the expectation of OP so much so that this *MUST* works. Many people find these methods useful and all we did was giving suggestions.

Did quite a bit work on reflow/reballing as well as chip replacing during the Xbox's RROD haydays. Was a good run before the slim version came, nothing to brag about it. I know you're good doing your job but how good you're doing your job is, no offence, not relevant of helping OP. You can suggest OP to try your way, and if it helps everyone's happy.

I don't act I know. I know because the rice method worked for me as well as many other people. It's an anecdotal evidence so before this discussion getting too religious, let's just leave it with that.

Since you keep referring to Uncle Ben, I hope you tried white rice, not uncle ben's praboiled rice. Praboiled rice doesn't absorb much moisture vs. white rice. Just saying.
[Galaxy Note GT-N7000 General] Rulinglionadi:
that rice myth is really funny.....i mean who can possible believe that ???

water damage is the worst nightmare for any electronic gadget...i lost my N73 and X6 because of it...NOTE is currently out of any kinda touch from H2O...thank god..:p
[Galaxy Note GT-N7000 General] emuX:
To wade in on the heated debate, rice and silica gel can work but you need to put it in a sealed bag or container, so the relative humidity of the air is reduced by the action of moisture absorption of the rice/gel.

The main cause of corrosion in pure water is electrolysis, when the electrical current is passed through the conducting medium and causes oxidation. If the phone is kept off from immediately after the water ingress until it has been dried out then it could be damage free.

In the OP's case though, it was SALT water which is caustic and likely to eat away and cause damage even if the phone's internals are completely dried out.

So anonymous is right but so is kawgirl to some extent! ;)
[Galaxy Note GT-N7000 General] dr. xp55:
Update

Thanks to all for the comments and suggestions. I have just put my phone back together after using some cleaning methods kawgirlval told me. We have a working mic and speakerphone! Everything is working as is.. Ok not everything. When I connect it to my PC, it doesn't recognize my phone, and actually my phone doesn't recognize that its connected to the pc. So now I have the issue of being able to transfer files to/from my phone. But it is charging. So I may have to buy a new USB port. I'm willing to spend the 15 bucks, not a big deal. I'll just use a wi-fi file transfer method

I used every suggestion, even the rice method. But in all honesty, I think what Kawgirlval is saying is that its just better to open your device and physically clean and dry it rather than use a passive method of just putting it in rice. Especially if there is corrosion cause rice really won't help with corroded metal. You def need to physically clean it.

Or maybe she's just saying eff the rice. :p

Yea I have a feeling I might run in to problems down the road. I just really hope not.

Anyways thanks a lot guys
[Galaxy Note GT-N7000 General] reinbeau:
Thread cleaned

If more arguing ensues, the thread will be closed and some will earn infractions. No one should take this personally, the rice thing will work in some cases, but corrosion isn't something that can be cleared up with it. Move on.
[Galaxy Note GT-N7000 General] dr. xp55:
ok scratch the charging. Its not doing that anymore either now. bummer. I could have dealt with the speaker and mic not working, using the hands free as a work around for the time being, but this one just sucks.
[Galaxy Note GT-N7000 General] PoisonWolf:
The salt in the water will kill your device.

Your phone will die. It is only a matter of time before more damage is dealt.

It is inevitable, sorry to say.
[Galaxy Note GT-N7000 General] kawgirlval69:
I hate to disagree but with the correct cleaning and treatment most phones can be saved.. I live at the beach and i do many a week.. Id say 90% if them i get working fully...
[Galaxy Note GT-N7000 General] sumsy2011:
I droped my galaxy s in my marine tank lol but i used one of these bags http://www.bheestie.com/ or somthing similer to it and worked . But dont try to power it on Untill dry
[Galaxy Note GT-N7000 General] CGI_Ram:
What about using contact cleaner to prevent corrosion?
[Galaxy Note GT-N7000 General] Cruzaders:
This is NOT a myth.

Thousands of years ago, the Egyptians used to preserve the corpse through the process of mummification. This technique consisted of removing the organs of the dead guy, and for a few days, the body was subjected to dehydration through the salt. The organs were stored in small jars of honey.

Some years ago, these organs were found intact in the honey. Honey had the power to kill bacterias and other decomposers coz osmosis.

The same is true for salad, for example. When we put salt in the salad happens a process of loss of water through osmosis, leaving each cell flaccida.

All these processes shows the salt absorption power

Why rice?

In some restaurants, or even at home it is possible to find salt shakers with rice inside to not let the salt create "stones" and block the little hole.

And the phone?

I'd suggest you to put your phone inside a small plastic bag with five or more tablespoons of salt and tie it (its important to not let the salt touch on phones buttons and connectors) and just let it for a day. dont open and make sure its tied very well. Remove the battery and the back cover.

I know it's gonna sound insane... but it really works.

but anyways, just saying: Im not responsable if something goes wrong. All i said is using chemical and physical theories. If nothing happens, well, u didn't lose anything.

Good Luck
[Galaxy Note GT-N7000 General] blindbox:
Corrosion? Seriously? CORROSION!?

One, your whole phone's PCB is OXIDIZED. The exposed tracks (which are only at the soldering points) are OXIDIZED. That means it can't get CORRODED any further.

Two, it's shortcircuits that's causing the problem (hence why it's recommended you leave the phone overnight to dry) but because we're working with low voltage and the fact that they have a small OCP circuit (perhaps), the damage might not be so bad and reversible after drying and cleaning. Cleaning's as important as drying here, you got salt on your device and that stuff makes water conduct electricity much better. Which means that moisture in the air can shortcircuit your phone despite it being dry.

Three. Speakerphone problem is probably because the water got into the drums

Rice works as it absorbs moisture. moving air doesn't work too well when you have tight crevices.

Who came up with corrosion? If it corrodes with air and salt the only thing that happens is that it oxidizes and no further corrosion occurs. This is copper and solder we're talking about, not iron and steel. Unless you're going with the big assumption that seawater is highly acidic.

I'm wondering what field do you work in. Heat from friction for evaporation? I could give you a short calculation to show that the frictional energy caused by moving air is about 0.000000001W. What helps in evaporation isn't the friction. It's the additional kinetic energy.

Drying agents such as silica gel works by removing water vapour. Removing water vapour creates dry air. Dry air makes it easier for water to become water vapour. Certainly works better compared to forced convection, and of course, having both at the same time is even better but that's a little hard to do. This is assuming you don't take apart your phone completely.

Forced convection does works better if you are willing to take apart your phone almost completely. Which in OP's case works and that's great.

P.S. Maybe my tone is a little bit rough but I wanted to clear up on the corrosion and the FUD. My family's practically full of engineers and I myself, am too. Not a friggin day past by without us discussing engineering related stuff like effects of moisture in atmosphere on equipment, designing the simplest solution to a problem, etc, to the point that I'd expect the talk coming when two of us in the family seat together, lol. It gets annoying sometimes.

EDIT: Anyway, overall, best to be thorough like the OP did. Open it up, clean it up, clean it up, clean it up. Then dry it.
