I recently dropped my phone into the toilet where it stayed for about 2-3 seconds. After that i pulled the battery, sim card, sd card and the other parts and let them dry for the better part of a day. When I put everything back it worked fine with the exception of the vol dwn button being activated when i press vol up. After a few days I am noticing the phone is barely holing a charge. It was off the charger for 2 hours and went from 100% - 66% (1 or 2 phone calls and a few internet pages). Should I replace my battery or is it my phone being messed up?
Not even worth troubleshooting. Just get a replacement from AT&T. Be sure to not tell them that you dropped it in the toilet

Isn't there a water sensor sticker on the phone somewhere? Im pretty sure the tab on battery is red too...
i hope u got that sweet insurance.... 125 replaces anything!!!
I think I might try getting a new battery..since the water sensor is there for some reason...
that will not solve your problem. there's another water sticker inside the phone right behind the usb-socket under the back cover...

If you can't exchange it then I would replace the battery. Chances are that it shorted out briefly and probably fried a few cells in the battery.
if the fuze does go in the toilet is it a good idea to flush it with rubbing alcohol to flush out the water and also cuz alcohol evaporates quickly? would that have saved it?
i saved serveral cellphones from certain death with the following steps:
immediately take out the battery (obvious)
dissassemble the whole phone (even the smallest pieces!!!) and flush everything with isopropyl alcohol
put the mainboard and other circuit boards in a bowl with alcohol and leave it alone for some hours
dry the circuit boards with a cloth and put them on a radiator for 24 hours
reassemble the phone and if you're lucky it will work again
i even got phones to work again which took a bath in beer and softdrinks...
Another trick that I have heard is to put it in a bowl of uncooked rice. The rice should absorb any moisture that is around it. I've never had to do it, but it seems like it would work.
Also, be careful with isopropyl alcohol if you use it. Make sure it's the highest concentration you can get. There is a lot of water (50%) in the "cheap" stuff. If you look around you can get 70% alcohol. You can't really get 100% unless you work in a lab...it tends to burst into flames at 70 degrees F.

At room temperature? Not without a source of ignition - I work in a lab and haven't had any problems with that. It is, of course, highly flammable though. You wouldn't necessarily want to use absolute (100%) ethanol though, as, unlike 96% ethanol, as it often contains benzene, which isn't especially pleasant.
Someone I work with recently spilled wine on their MacBook and tried to recover it by flooding the machine with ethanol the next day, but since it was turned on at the time it seems that it shorted immediately and the damage was done. Maybe my old Psion Revo could have been saved from a fall in a puddle which it initially survived, though.
Either way, replacing the battery would be the obvious first thing to do if it's otherwise working fine (bar the volume controls). If it's shorting somewhere nonessential that could feasibly drain the battery fast as well, though?
I may have possibly water damaged my Captivate last night. It was in my pocket when water spilled on my lap, and I didn't immediately take it out. Very stupid of me. The USB port was open so I'm thinking liquid may have gotten into there... Also, there were water beads on the inside of the camera lens.
My recourse was to take it apart and try to let it dry out. Initially it wouldn't do anything upon being plugged in to the charger, so naturally I thought it was bricked. I've let it sit all day on a dry window sill next to the radiator. After putting the battery back in and plugging it in a little bit ago, the phone surprisingly booted up. Here's where I'm at now:
The phone boots normally, however if I plug it in to the charger I get an error stating Battery Temperature too high or something, so charging is paused. Does anybody know what this indicates?
Secondly, after being on for a minute or so, the screen gets screwy. Dark transparent overlays start flashing over everything and it gets unresponsive... I haven't left it on like this long b/c I was afraid something worse would happen - I usually rip the battery out of the back to shut it off.
My phones currently pulled apart and drying in the window sill. Whatever water got on/in it is not visibly there, however I understand some parts might still be wet.
Any advice? Also, I believe the water indicator on the battery and near the pins where the battery dock in the phone are both fine. They're white squares and haven't changed color. Any chance there are other indicators?
The phone isn't insured and I bought it back in August. Would warranty possibly cover this or will they know about the water damage?

well you want to put in rice, so that the moisture is gone
rice it for sure. but warranty WILL not cover it UNLESS the tabs on the battery and phone are white (It might not have gotten wet if it was in your pocket)
if they are still white, or if your phone is white and battery red (then buy another battery) and get to the store and tell them you don't know what is wrong with it. The only indication that it is water damaged is if it is red and those tags are notoriously faulty so you could always argue your way through it if you have an account in good standing.
best of luck.
I know someone who "claimed' that insurance was supposed to be added to the phone when he got it and noticed that the person didn't do it properly (the guy was new so it helped his cause) and the manager of the cor store told him that they'd do a courtesy replacement and charged him the 125$ for a new device.
you could go that route should you need too...
I don't have access to rice at the moment... Would it do any good even if I absolutely can see no water anywhere in/on the phone?
Am I doing my phone any harm/potential harm by trying to turn it on every once in a while, or should I just let it be for a few days?
Take the phone apart and focus the strongest fan you have on it over night. It's probably best to not turn it on for awhile. Maybe if you focus a blow drier on it for perhaps several hours, air will find flow through the small openings within the case.
You may not be able to dry some parts of it unless you do a complete dismantle, but that may require special tools
Consider shipping it to get repaired only as a last resort, as I've read some bad reports about that.
Rice or some other dessicant is the way to go - it will pull moisture out. Also, turning it on (even putting the battery in) is bad - you are powering circuits and possibly creating shorts where water is present. You may have already done permanent damage.
If you get electronics wet, the best course of action is to remove the battery and put it in a bag of rice for a few days.
Now that You have the phone apart get an alcohol pad and gentley scrub the main board. Sometimes when liquid touches the main board you will get a white looking residue. If you see anything like that simply wipe it off. I dropped my phone into a trash can at a very popular teriyaki restaurant here in Las Vegas my phone was submerged into a deep bath of teriyaki sauce. I quickly pulled the phone from the can and wiped it down vigorously. I was excited to see that it was initially working unfortunately this was not the case by the time I got home. The phone would not turn on for a whole week, until I decided that I was going to open her up. I found a tutorial on line describing a complete break down of the captivate. Upon opening it I found I was able to see exactly where the teriyaki had interacted with the electronics due to the remnants of an oxidized white film that was present on various parts of the main board. I grabbed a alcohol pad out of my first aid kit and began wiping it down to remove all of the white stuff,put the phone back together and to my surprise it turned on. Hope this helps!
Thanks for the info guys.
How would I go about getting to the "main board"? Taking out the battery and looking inside it only reveals where the battery connects, where the SD card and sim cards can go... I'm assuming if I remove the little screws around that fixture I can get to the "main board"?
I think I can see some minor corrosion around where the sim card connects, but I think I *should* be able to clean that with some alcohol.
The phone seems to be working fine (I've yet to put my SIM back in it, though, so no idea if the corrosion around there is affecting it at all). I just booted it up and was able to get on the web (wifi), run apps, everything just fine. Didn't get the flashy screens I mentioned earlier. However, if I plug in the USB charger, it still gives me the temperature error. I didn't keep it plugged in, however it did make me realize something:
The errors I was getting before, where the screen went all wacky, only happened if the phone was plugged in to the wall. Is it possible my battery is busted, or do you think the USB charger is busted? Remember that port was open when it happened.
Any thoughts? New battery? Or do you think I won't be able to charge the phone via USB charger any more?

yes you are, because if there is water or moisture internal, it can short circuit, also rice will help dry up the phone completely

If you've never taken apart a smart phone before, and reading your first question, I'm going to assume that's the case, then I strongly advise you not attempt it unless you are willing to either A) buy a replacement after you break it or B) invest time/money into repairing mistakes you've made. This phone is not as difficult to disassemble as some, but I wouldn't want to break that $150 amoled screen.
No, removing the screws will not simply get you to the mainboard. It's more complicated and nuanced than that.
I'm a new user so I can't post the link but if you google Tech Republic Captivate tear down [/B]there is a website that will show you step by step how take the phone apart. There are two screws under the clip you pull down to take the back cover off. Be careful when pulling it back to expose the screws. I tugged on it pretty hard with no problems, but I imagine it could be broken if you pull too hard. Good Luck! It's actually really easy to take apart and the various ribbon connectors on the main board are really easy to unplug and plug back in after cleaning it.
So what do you guys think I should do if I'm still getting the battery error with the thermometer and yellow caution sign? Buy a new battery? Or do you think its the USB jack? Has anybody seen this before - the battery was working fine as long as it was not charging.
I'm trying to decide between a) buying a new battery, or b) buying a wall-mounted battery charger since the USB won't charge the phone.
Anybody have any experience?

I think you need to be careful about who you encourage to dissect their device. This guy asked how to get to the mainboard. Clearly, he hasn't opened a smart phone before. Telling him it's "actually really easy" is disingenuous at best. Performing smart phone repairs properly requires experience. I'm certainly not suggesting that noobs not try to fix their phones, only that they are made fully aware of the risks.
My Captivate was fully submerged in dirty water. I followed some instructions online and it's been working fine for over a month now. If your water-detection stickers are already red anyway, and rice isn't working, I recommend it:
1) Remove battery, SIM card, SD card
2) Submerge in a bowl of distilled water and gently agitate. This helps clean the insides. Distilled water (not spring water) does not conduct electricity.
3) Next, submerge in a bowl of high-quality rubbing alcohol (~95% pure) and gently agitate. Rubbing alcohol displaces water, removes corrosion, and evaporates quickly. (It's also flammable, so have good ventilation and no open flames nearby)
4) Leave it out to dry for two days or until it no longer smells of alcohol.
BTW I wouldn't dry it too close to a radiator, the heat may damage it.

Not really. Once the screws are removed..including the two hidden by the battery cover lock slider...you can carefully pry the cover apart using your fingernail to get to the the internals. I have done it several times and am no expert by any means. Just don't yank like you are opening a present on Christmas morning.
Although I am mystified by the op stating they have no access to rice?! That should always be the second thing one does after a moisture incident...right after pulling the battery and sim. I guess in this case a trip to the store with a couple bucks may have pushed that to step three though..

Hello,
by a rediculous accident I forgot my HTC Diamond in the pocket of my jeans when running the laundry :-(
Afterwards, I opened the cover, took out the battery and let the phone dry out for 2 days. Now I've put it back together, and connected it to the charger. The "ring" is flashing, so the battery is charging but the phone itself is not starting and the display remains completely black, not even the vibration kick on starting...
Is there anything I could do? Or perhaps there is a chance to get out some photos I have shot earlier, would also be something...
ive heard that taking apart your phone and leaving the parts in rice can help (because the rice absorbs moisture)
Off topic:
I read one Desire went through a washing sequence in a washing machine in Desire spesific forum and now this?
Is this a new hobby? I mean... washing smartphone

If the photos are on your micro sd card, you may be able to plug that into an adapter and plug it into your PC and gain access to them that way. Just be sure that micro sd card is thoroughly dry before doing so.
WORKING !!!
Hello,
thanks for the replies... This morning the phone booted!!! I was able to download the photos!!! But the screen has stains, obviously the remaining water.
PLEASE advise on how to dry that thing completely !!!
I think that I'm gonna pass on the rice thing.
@aaa - YOU ARE A JUNKA$$ !!! You think that's really funny?!? Especially when I'm currently TIGHT on budget and need the money for other things and the next phone is planned no earlier than Christmas... I'm hesitating whether you're a real human being...
You can dry it completely in an oven for three hours at thirty degrees or so. I've done this three times. If you have a fan forced oven, just turn the fans on, that'll be enough.
A safer way (if you can obtain it) is to leave the phone for 24 hours in a bowl of dessicant silica gel. You'll often get a small packet of silica gel when buying new electronics or other moisture-affected things. That small packet is enough, just put it in an airtight bag and leave it for 24 hours.
The next step would be disassembly and a thorough swabbing with denatured alcohol, but that's pretty extreme and only needed when the device isn't booting.
Some LCDs are hard to get moisture out of, some are not. Leaving the phone with the silica gel for longer will have a better effect. As the previous poster mentioned, rice also works (quite well), but takes longer than silica.
Good luck with it!
Another thin that will absorb moisture is common table salt. Take the phone apart very carefully. Remove battery first, make sure you're grounded as well.
Hello everybody.
thanks a lot for the numerous advices...
Unfortunately, I have more to report...
The phone dried out and booted 2 or 3 days later, as I said. The stains on the display disappeared as by magic one day later.
Everything was fine for a week until I launched the camera 2 days ago. The backlight of the display went off and came back only after removing the batter for 15 minutes.
Now the backlight is going off pretty often, sometimes it requires to remove the battery 1-2 times before it starts working again and yesterday it happened that it got activated again when I got a call...
Any ideas please?
And also the phone keeps overheating from time to time without real load (GPS or wi-fi) which dries out the battery. But I had this problem also before the laundry
Sounds like that moisture in the LCD unit left a bit of residue and is shorting the backlight somewhere.
Only option there would be to disassemble and swab the LCD boards and cables/connectors with denatured alcohol.
Alternatively, a new LCD unit should fix the problem if it persists, just make sure you alcohol swab the connectors before plugging them back in
Someone also mentioned drying out in salt before. While that does work, salt is extremely corrosive on solder and SMCs, so I wouldn't recommend that route.
i heard hair dryers are the bomb at the screen moisture, just take off all that you can and blow dry it.
I just don't understand your refusal on using white rice. It have saved countless phones.
Uncooked white rice is VERY mosture negative. Just put layer of rice, put your phone on it, cover it completely with white rice, seal it in. Ziploc could work too.
In a day or two your partially dry phone will be bone-dry. If it was soaked still you could first try to shake out water as much as can, soak it in distilled water to remove minerals, then white rice it for 3 to 5 days.
I had this problem with my Touch Diamond. Everything worked, but while i was trying to dry it I broke one of the battery "hinges" but the phone still worked after except only with black screen. The best thing to do probably is just leave it for a couple of days and hopefully your phone will be back!

exactly what ive said. ive read everywhere that rice is one of the best solutions out there
Like was said before you most likely have some corrosion on a few contacts, if you have about 6 bucks you can spare you can get residue free contact cleaner in an aerosol at radio shack or any electronics store and save yourself having to scrub each contact and connector. Just tear the phone down down spray all the contacts and connectors with contact cleaner let it sit for a few then spray it down with air duster to get any thats get under the resistors, in the connectors, etc that hasn't dried; let it sit till you're positive everythings dry and put it back together. Does the same thing as alcohol just alot less scrubbing.

Hello,
thanks for narrowing the problem down.
But for me it looks like something different, because:
1) I have been using the phone for 1 week without any problems and it got screwed after I've launched the camera app for the first time
2) The backlight works when I power on the phone. But its stop is event-triggered, like when I launch the sound or video player or when I get a call... Similar events would trigger the backlight back on.
Perhaps reflashing the software could fix that?
I went to a shop today and put another battery. The phone booted, anyway without any backlight, twice...
At least the device is still alive.
There probably was a tiny water bubble and it messed with phone when you turned camera on.

Either that or a short in the cameras circuit from corrosion, either way i'd pull it apart before it gets worse and check it out.

Every time when I charging use cable, I can feel the small vibration on side of phone when touch it.. especially on top of phone .. Does everyone got this issue
Sent from my [device_name] using XDA-Developers Legacy app
I'm not seeing this on my N20 Ultra.
What happens if you use another charging cable and power brick and or wireless charging.
Is it a vibration or electric current?
Probably a coil in the phone's power converter.
Switching transformer or such.
It happened sometimes for me too with almost any phone, and it was more likely to happen with metal ones. Usually it goes away after a bit.
The same with laptop that got a metal casing too.
Wouldn't have thought you could feel 11v max
Sorry guys but you wouldn't feel that low voltage even if it was 20V
You wouldn't feel it
Maybe your fingers/palm vibrate when you slide along the metallic bits of the phone making it feel like voltage
Umm... people have been severely shocked by car batteries.
One kid decades ago it was reported killed himself with a 9V battery.
It all depends on the resistance in the circuit. Most times 14 volts won't be felt but when it is it's a shock.
Don't handle battery terminals with wet hands including sweat.
In this case I think it's a physical vibration.
Some people have much more sensitive levels of physical perception. Tesla was said to have extremely acute senses... and he was not stranger to shocks.

The 9v battery thing was 'apparently' if true, because he pierced his skin with the probes allowing the blood to become the conductor passing through his heart (Although I find the story a bit far fetched, the theory is true, not sure about the story), a finger covered in skin touching the edge of a phone is not going to be felt / give a shock coming from a phone charger, stick it on your tongue maybe but not your skin, not enough voltage to make it through your skin in a phone charger
Car battery won't shock you either, touched both terminals many times using jump leads, HT leads / spark-plugs on the other hand give quite a nasty shock if you are also touching the chassis, in the rain

I first read the 9V battery story 40, 50 years ago in print. It's certainly possible... but last time I tried tracking it down found nothing conclusive. However massive as the internet db is, much info is missing.
As for car batteries I can verify from first hand experience they can give you a shock:silly:
Don't ground yourself out...
My 12KV 30 ma neon sign transformer though can give a nasty shock if your careless enough to touch one terminal.
Even along a plastic screwdriver handle if any sweat is on it. It will ground you out through the air or a hardwood floor... fun times

Had many nasty shocks, the power circuit board from an original Playstation, touched the back of the board where the capacitor pins were, that really hurt badly, and strangely I managed to do the exact same thing again about 5 minutes later lol
Also learned that turning off a lightswitch does not cut power to the light fitting the hard way too

It's always quite a surprise...
One of the scariest shocks I got was from a 30" CRT I was replacing.
Basically a giant HV vacuum capacitor.
They can hold a charge a very long time, even can collect a charge sitting there from static electricity and they have "memory"; simply discharging it once isn't enough as they will build back a charge. Even though I had shorted it out for over a minute, when working to put it in, I knocked the lead off. In less then a minute it built up enough voltage to tag me... and of course it did.
The shock wasn't that bad, the real danger was dropping the CRT and it imploding. There's no protection on the back to keep the glass shards from flying out at high velocities. Techs have been killed like this.
I kept my grip... and successfully repaired it.

haha yea, I was very inquisitive as a kid about all things electrical, my bedroom floor was covered in PCBs and chips and wires, (surprised I'm still here to tell the tale tbh) but CRT TVs were the one thing I didn't play around with too much, they just looked like certain death to me, those thick high voltage cables and suckers were far too intimidating at that age (says the guy who did the 9v battery on the tongue trick with a mains cable plugged into a 240v socket and switched on, luckily the reason whatever device wasn't working was because the live wire had come loose from the back of the socket... can't even imagine what my mouth would have looked like if it had not...)

Had many nasty shocks, the power circuit board from an original Playstation, touched the back of the board where the capacitor pins were, that really hurt badly, and strangely I managed to do the exact same thing again about 5 minutes later lol
Also learned that turning off a lightswitch does not cut power to the light fitting the hard way too

Bah-ha-ha-ha when I was around 10 yo I stuck my index finger across the 120VAC plug prongs while they were making contact to see what it felt like... once.
The old huge plugin disposable magnesium wire flash bulbs.. once set one off in my hand with a battery. Surprise, they really get bright and... hot.
Mild first degree burns, nothing much but for the first few seconds were priceless.

Every time when I charging use cable, I can feel the small vibration on side of phone when touch it.. especially on top of phone .. Does everyone got this issue

I saw people mention this for other phones and for wireless charging. To some extent I think your right about "leaking electricity" but in a different way. I think the high power thats going into your phone is causing some electronics to jump to your speakers. I could be wrong, especially if the internal speakers dont use copper coils. But if they do, its very possible.

Pretty sure all the internal speakers are piezo.
It's quite possible though with wireless charging they are feeling the internal pickup coil vibrating or with wired, the power converter's choke coil(s) vibrating.
Coursing with raw power...
People really scrutinize their devices far too closely... have pity on their better halves

One of the scariest shocks I got was from a 30" CRT I was replacing.
Basically a giant HV vacuum capacitor.
They can hold a charge a very long time, even can collect a charge sitting there from static electricity and they have "memory"; simply discharging it once isn't enough as they will build back a charge. Even though I had shorted it out for over a minute, when working to put it in, I knocked the lead off. In less then a minute it built up enough voltage to tag me... and of course it did.
The shock wasn't that bad, the real danger was dropping the CRT and it imploding. There's no protection on the back to keep the glass shards from flying out at high velocities. Techs have been killed like this.
I kept my grip... and successfully repaired it.

Been there, done that... worked in Diagnostic Imaging Field Service for 30+ years - hang on to that baby, the charge will dissipate!!! The alternative, like you said, could be a "glassy" death!
So I've had this phone water damaged. I left it in rice in a very hot room for maybe 4 months. It boots into recovery and download mode fine and the screen works well. But when i boot it normally after flashing fresh Stock Firmware (It didn't boot before just stuck on splash). I plug phone into charge and the Samsung charger plug sound plays. That means its actually loaded into Android. Any ideas how to fix this?
I thought of replacing the LCD but since Download and Recovery shows up fine then it shouldn't be it?
You need to pull the battery asap after water exposure. The phone needed to come apart right away. Perhaps the mobo has conformal coating but the connectors do not have any protection.
You need to pull the whole thing apart, inspect and dry it completely.
Its long term prospects aren't good.

It's been dried for a whole 2 or 3 months in rice and a hot room. Phone boots fine now but only to Download mode or Recovery mode. Screen doesn't work past splashscreen when booting

It's been a few months after it's been water damaged I havent run it since BTW

No I mean i tossed it in rice for 2 months in a very hot room and left it there. I tried to take the back off but it started crackling so I didn't try to take it further. I thought the battery might blow up.

The battery won't blow up unless you get it really hot. You can't leave water in these devices at all, every minute counts especially if it has a battery.
Sorry but the rice method doesn't cut it.
My Buds case fell in my coffee and sunk to the bottom. Fished it out and tore it apart on the spot. Flushed with RO water, then rinsed with anhydrous isopropyl alcohol using centrifugal force to get as much of the alcohol off (no compressed air in the car) then let it dry.
Amazingly it still is working a year latter; I got lucky, but I was also acted fast and did the right things.
Aside from nose diving it into my full cup of coffee.
I wouldn't invest to much money into this device. Water damaged electronics are insidiously unpredictable and there's no time limit to when it will fail again even if you do manage to get it working.
Dirt minimum; take it apart and carefully inspect it. Pull the micro ribbon connectors and inspect the contacts. Make sure they're completely dry.
Anhydrous isopropyl alcohol (99%) can be used to displaced water. Be careful around LCDs if present as it can poison the liquid crystals.
Exactly the same story with a smartphone at work. The phone starts into recovery with no prolem, the display is working fine. But when I start the system it only shows me the "Samsung Galaxy A51" lettering, "Secured by Knox" and the "Powered by Android". After booting the display remains black but the device gives a feedback when pressing the volume up/down buttons.
Is there any way to reinstall the whole OS? Or maybe authorize the Fingerprint of my PC to check if there's any display output via scrcpy?

It could one of many possible damaged contact surfaces or shorted/open surface mount devices including cpu or ram flat packs or mobo traces. Even after the water is gone if it wasn't promptly removed* damage will continue to surface long after the incident.
You need to tear it apart asap. Even a few minutes may be too long.
Water damage electronics are insidious failures waiting to happen.
Cut your loses.
*prompt removal is no guarentee but greatly improves chances of success.
