[Q] Another Water Damage Thread

Howdy,
Long version:
I left my galaxy note on the counter in my kitchen which is apparently not quite level. Overnight water pooled under it(never submerged, even partially). I did not notice until my alarm went off the following morning. As of this time it was still functioning properly. I moved it, wiped off the water. Took the protective case off and wiped the water off it was well, hooked it up to the charger and went back to sleep. 15 minutes later the vibration function went nuts while it popped up complaints about low battery. I say the vibration went nuts, because it wasn't the sustained vibration like you normally get it. It would cycle on and off about every half a second. I panicked, turned off the device and removed the battery where I noticed that the battery was wet, and under the battery as well.
So I wipe it off, put in a bag of rice and go back to sleep. Approximately 15(yes, way too soon) hours later I pull it out, put the battery in and turn it on. Works fine. few hours later I hook it up the charger and it immediately complains about the battery temperature.
Short version:
Phone at in a pool of water for 5+ hours, never fully submerged. Basically if you poured water on a level surface and sat your phone in it, thats what happened.. Anyways Water worked its way inside the phone(based on disasemble that occured later), and started vibrating randomly. took out batteyr and left in rice for 15 hours. Put it back together attempted to charge, phone complains battery is too hot immedately.
Observations:
I take out the battery and disasemble the device down to the point where the circuit board is separate from the display.
The far right ( +) connector that touches the battery appears to be slightly corrodeded. I rub it with a cotton swab to clean it. From watermarks it doesn't look like anything else got wet and by now its completely dry. I don't see any 'red' spots or stickers, but I'm unfamiliar with the water damage indicators, and the information i found from searches was innacurate(no white dot on top of battery, no red marks anywhere on it)
Panic
I put it back together try again, same deal. The phone doesn't seem to have a way to view the battery temperature reading(*#0*#), so I downloaded an app called 'Doms diagnostic tool' which indicates that the battery temperature is pegged at 80 degrees C and it does not fluctuate. I don't know if this app is actually reading anything though.
Can someone who has a working phone try this out? App is free.
Is it worth putting it back in rice even though its dry even on thorough dissemble?
Any idea how to get legit data from the sensor to verify if its shorted out etc?
Would a replacement battery with out the sensor resolve this issue?
Anyone have pictures of where water damage indicators are?
I searched thoroughly and found no answers besides taking it to a service center. Since I'm in America, and this is an international phone, I don't believe the manufacturer will honor the warranty even if the phone shows negative for water damage. My service is ATT, but I bought the phone at expansys( i think).

best at this point is to check your insurance, if its covered. In some countries I read this is covered as it was accidental.
I would recommend goong to samsung and let them check it, with the true story ofc. Now if they find whats wrong, they might be lenient, or not. Anyhow then you know whats broke, and you can decide to fix it for yourself or have it fixed. At this point it sounds like corrosion on one of the boards, or shorts somewhere.

Repairing water damaged phone

Hi,
i send my phone down the river and probably killed it. backplate was broken and charging lid as well, there is no warranty any more.
i dried it for a week in a box covered with rice and tried to turn it on afterwards. No reactions on buttons, but after i plugged in the charger, the LED got red and Display turned on showing the "Sony" Screen. after a second or two LED and screen went black and the procedure started again. and again. after a few repetitions i put the plug away. so i didn't charge the phone any longer than ~5min and have not plugged it to the PC.
first question is if someone has encountered the same symptomes and can give a statement of chance to revive the phone. Second one is: Where to start? there are lots of guides to disassemble the phone, thats not a problem i think, i have all the tools i need and a little bit technical knowhow. I want to start checking the battery, pretty shure its dead. afterwards i want to check the board for signs of corrosion. but then?
grateful for any tipps, especialy want to know whats the real death sentence for a water damaged phone. after i have seen the screen working i thought main functionality is there and only the battery died.

I would leave it plugged in and see if you can build up any sort of charge in the battery. It seems that changing the battery would be an obvious first step, if you can get enough charge in the phone to fire up the mainboard, then you will see what else needs to be changed. leave it plugged into a charger for 24 hours.
Do you want to repair it to salvage what data is on the phone or is it financial reasons? tbh the cost of new mainboard and battery, plus replacement back screen is going to be more than a second hand phone off ebay. If it's a science project then bravo, not enough people try to rescue thier old kit from the bin, but I'm saying there are easier options than pulling it apart.
Having never pulled a phone apart myself I can't really offer any more advice, but you might want to drop @Chamelleon a PM, as he regularly contributes with hardware fixes and knows his stuff.

its more about financial reasons, data is all backed up. Buying a new phone should be the last option. i want to repair it cause i like repairing things and i want to make clear that the phone is absolutely dead or not. i dont think i would buy a new mainboard/display/battery if i am not completely shure that this will fix all problems. in this case id rather buy a new phone.
i am a bit afraid that if i charge the battery for 24h and still have a circuit on the motherboard i will completely destroy it.

A week in rice in a warm place means there's no moisture in the phone.
The phone won't be damaged by trying to charge the battery and you need to find out if there's anything working from a full charge.

I recently had a waterdamage too. I took it apart and i saw that there was some corrosion on the board by the display connector. I put the mainboard in isopropyl alcohol (you can get that in the pharmacy). I carefully cleaned the affected part with a soft toothbrush and let it dry for a while. And now my phone is back a life and everything works as it should
Good Luck!

Well, turns out this guy is right. Phone is working after charging. Vibration is dead and there are some residues of the wather in or behind the display, but nothing else i can find now. i think i will still disassemble the phone, and clean all parts. Maybe i will replace the vibration motor, but i think i can live without one...

Moisture sensor too sensitive.

I can leave my note 8 in a humid room (such as the bathroom during a shower), and it will trigger the device to say that there's moisture in the device. Recently, i even had it in my pocket while I was working, port down, and it still triggered. The device can sit on a desk in the living room or bedroom for several hours without the warning going away. Anyone else having this issue? Or does anyone know of a way to disable this feature? It's a major pain in the neck, and moisture was never an issue with my Note 3. I understand the idea behind it, to stop the charging process if it falls into water (which would generally require an idiot to begin with), but it's too sensitive in my opinion. Already, it has prevented me from charging my device when battery was critically low on at least two occasions.

Sounds like moisture is getting into your device. I'd return it.

So, the problem was corrosion in my USB port. The Sprint store couldn't do anything because it's "liquid damage." Thankfully, I was able to clean the crud it of the port, but it's still a little finicky. Wireless charging still works fine... Thankfully. So, corrosion will trigger the moisture sensor... Ugh. At least I got it taken care of now.

You can only charge with wireless charging?

I used some vinegar and the eject pin to scrape the contacts clean, and corded charging works too now. But the moisture sensor doesn't stop wireless charging.
Probably would be a good idea to invest in this...

I would call samsung. For a device thats rated to be able to be under water for up to 30 minutes......corrosion in the usb port shouldn't be a problem in my opinion.

Just spray some electric contact cleaner in there perhaps? Bizare that Samsung would not use corrosion resistance contacts for the USB port.

Perhaps, didn't have any, so vinegar was the next best thing.

Water Damaged, Bootloop Huawei P10

Okay. I really need help here guys. So long ago I had water damaged my phone and I got it working again. About 2-3 months later the battery started acting up and showing percentages in 10s and soon after could only use it when it was plugged in.
Now, whenever I plug it in it immediately shows the Huawei logo and starts to boot up. Which I don't like because I remember it used to show a green battery circle before. But nevertheless its in a bootloop now. The weird thing is, I can't use the volume up button method. I don't know why. It just carries on.
Maybe I should wet the power button with water if its been held down causing it to immediately boot up when plugged in? i dont know.
If anyone could guide me or suggest what to do I would honestly be so appreciative. Thank you so much!

Could be a hardware issue. Water is causing corrosion to metal parts and if there is still a bit water inside your phone the corrosion can damage parts of the hardware. It's risky to use the phone without drying it completely. In the most bad case the battery can be shorted by the water which can cause a battery fire or explosion.
Bring your phone to a repair shop if you're not able to open it by yourself. But I think there's no hope anymore.
You should've let it dry completely before using it again.
Don't put water again to parts of the phone.
If you're able to open it, disconnect the battery and check the logic board for corrosion and water.
If there's still water you can remove it early by putting the logic board on a piece of cloth and wait for a few days.
You can also try to clean corroded parts with pure alcohol and cotton swaps.
Get a new battery to be safe, check if the old one is misformed. If it's so, don't use it again - NEVER!
Li-ion isn't a funny thing, it can be very dangerous.
If there's a shortage inside the battery or it's physically damaged it can burn out. The technology is based on cells. If the cells are getting shorted each other, a chain reaction starts and inside the battery the current flow can get so high that the battery start burning. It stops when every cell is damaged and the voltage is 0 - it's hard to extinguish such fires. There are many videos on YouTube.
So don't make fun with this, just do something if you feel safe in electronics. If not, go to a repair shop.

Xperia XZ2 data recovery after liquid damage

Hi folks,
I have been sitting my friend's phone around for a while.
I somehow made it to unseal the phone, I guess by using an air pressure gun.
My approach was to open it up, clean it out and try to restart it.
Mostly with one approach, making a backup of the pictures.
Sadly, I was not patient enough and partly destroyed the screen.
But after is resembled most parts lossy, I was able to restart the phone.
As the screen was too hard damaged, and it took a while till I got a new one, I took the phone aside.
New screen has arrived after a while but shockingly the screen doesn't turn at all even with the old screen.
As the battery was deeply discharged, it charged it a little janky and messed up the port.
But still not working.
So my last ideas was to tried starting it without the battery, which didn't work.
So here is my question, will it start without the battery in at all or the other way around, could a broken battery terminal be now the main cause for not getting the phone started.
The alarm is still working as well as the vibration and the indicator LED which stays more or less only red.

It needs the battery to boot up. Without the battery the phone likely won't have enough current to boot.
You use heat, anhydrous isopropyl alcohol, plastic picks to get most of these phones rear covers off. Never compressed air.

I would guess that it is not the current, more the basic system how the battery management is realized.
No the compressed air wasn't the reason, it was more the reason for the water leakage.
As the rubber gasket got misaligned with using it to clean up the usb c port.
The display got cracked because I assumed the display would be more narrow like I was used to with amoled ones.
So my spatula dive in between the LCD and the backlight the rest was made by my manual force.
I think I will order a spare battery and will retry it..

Make sure everything is completely dry. Leave battery disconnected until dry.
Do not expose LCD displays to any solvents including isopropyl alcohol as they will poison it.
Things happen... the second time is always easier.
The battery is a cheap fix if it works.
