How clean was the water in the puddle? If it was clean, you need to give the phone enough time to dry. Remove cover, battery, sim, etc. place phone in a bowl of dry rice and let it be for a few hours.

not clear but it wasnt deep puddle ~ aroud 3 millimeters

Well do you have dirt in the USB slot? May be use some canned air on the port?
I once dropped my old dumbphone in a dirty puddle. I then washed it with tap water and alcohol, opened it up as much as I could, and dried it for a full day. It then turned on no problem.
I am NOT advising you do the same with SGS2!
Just try to clean with alcohol pad the USB port, the battery contacts on the phone and battery, and let it dry more. Do NOT drench the phone with alcohol or water, just wipe the contacts with cotton pad wet with alcohol.
Drying it completely is the key. There may be some water still shorting some contacts around the USB port making the phone think something is connected.

Water damage

Hi. My phone got wet in my jacket pocket while riding my motorbike. It was probably wet for an hour or so before I got home and started attending to it. Obviously as it was in my pocket it didn't get submerged or anything, but i still found water residue inside. I took it apart, submerged the motherboard in isopropyl alcohol for a couple of hours and then left it to dry. Today it is booting up however I have noticed a couple of problems.
The phone will not start up unless it is connected to a power source when I try to start it. It will stay on if i unplug it.
It won't charge. First time I booted it it said 41%. As soon as I restarted it had dropped to 17% and is now falling even when plugged in. It does claim to be charging when connected however.
The front camera looks like one of those face-morphing apps (Is there's water around the lens or something?).
It also feels quite hot around the top of the phone when it isn't doing anything.
The loud speaker is not working (fine, I'm guessing that's just a case of swapping it out).
Could the first two just be the battery or some sort of issue with the USB interface? Any ideas how to fix these issues? Thanks!
Clean your usb port. I sometimes clean it with 99% alcohol and a toothbrush when I got some moister damage.
When you charge it, check battery stats and see if it says that it's usb connected.
If so, then you might need to flash a custom kernel (I used Ktoonz for it) and raise the charging stream true usb.
Because your usb port got wet, it thinks you are charging true usb. When charging true usb it will charge way slower. It's als probably the cause for your phone getting hot for no reason.

I will try that now! Any idea why it won't start unless connected? I've just not a new battery, no change on that issue.
EDIT: It's now starting fine. I'm waiting for a replacement USB connector to hopefully fix the charging issues. It's still getting hot when it's just sitting on the table and the battery is draining at light speed.

Good to hear it's booting again. From my experience these issues are temporarily and will disappear over time. The kernel and changing the charging speed fixed the same issues for me. I'm now running my normal kernel without any tweaks. So you might try it before swapping the connector. But that's up to you.

I had already ordered the bits and they were only cheap so went ahead and swapped them out. New USB connector flex and new speaker. Frustratingly I still have no sound. It's charging fine but the battery is still dropping off a cliff (like half an hour from fully charged) and it's still getting hot. I even gave the motherboard and connectors a good clean with high purity alcohol and some cotton swabs. Could the board have suffered permanent damage potentially?
Strangely, none of the water indicator stickers have triggered and it's still in warranty so if worst comes to worst I guess I can go down that avenue.

Thinks it's charging, but it isn't

My S5 thinks its chargning, and the stops charging and charges again and so on all the time even though the charging cable isn't plugged in.
I've changed the micro-USB port inside the phone, which didn't fix it. It won't charge through the micro-USB port, it doesn't get recognized as a storage "thing" on the computer either, which it did before. Also, it works charging it wirelessly though. I've also factory resetted it and wiped the cache in the bootloader menu, without that fixing it either. I did get some water on the phone, which came inside the back cover the day before this problem occoured, which probably is the cause of it.
Any suggestions to fixing it? If not I'll buy a new phone.
Thanks in advance

Should have left it to dry out before using it or putting the battery back in
Try washing it with Isopropyl alcohol and leaving it to dry fully

I did dry in rice, do you mean washing/dunking the entire phone without the LCD and battery?

Clean the board of the phone with the alcohol yea, the alcohol will remove any residue left over from the water that could be causing the problem, and will evaporate off leaving no impurities behind
It's the impurities in the water left behind on the board that cause the problems

How to get rid of salt water Rust from S7 edge USB port

I took My S7 Edge into the Ocean. And now The USB Port is not Working. I guess Some chemical reaction with chlorine made the USB port Not working.
I am not able to charge the phone.
Phone Works fine due to water resistance of S7 Edge except MicroUSB port.
How to Clean the microUSB Port to make it work again???
make use of your warranty
if theres salts.then u need more water.. if its rust then u can use something like these http://www.wikihow.com/Remove-Rust-from-Metal
What I would recommend is the following:
1 Bottle of 99% Isopropyl Alcohol
> You'll can find it on-line or at your local department/hardware store. If you can't get 99%, grab a bottle of 91%. In regards to electronics, the higher the concentrate the better. Do NOT use anything lower (e.g., 70%/50% etc).
1 x NEW Toothbrush (Soft or Medium bristle)
1 x Lint/Streak Free Cloth (for clean up)
Apply the solution to the cloth and try to clean up any excess rust first on the housing. Follow this up by inserting your toothbrush into the solution and gently rubbing it against the contacts inside the USB charging port.
Continue until all rust is removed.
The higher the concentrate, the quicker it will dry however do ensure you use it in a well ventilated area.
Best of luck!

Lemfo/Zeblaze charging flaw

After behaving normally for months, my Zeblaze Blitz (LEM3) didn't start charging when I snapped it into the charging clip. The problem turned out to be with the charging pads in the watch-back, and is probably generic to any watch that has this style charging system, so consider this if your watch is not that old (i.e. not a worn our battery) and it stops charging.
One of the pads is leaking moisture/sweat to the inside, where it corroded the spring-loaded pin, which became stuck in the compressed position and stopped conducting as well. See attached pictures.
After cleaning with a cotton swab and alcohol, the watch resumed charging normally for a few weeks, until the pin corroded again. This time cleaning the pin didn't help, perhaps because too much of the gold plating has flaked off the pad and it's no longer conductive. Again, see pictures.
Followup:
Charging OK again. The goldish charge pad plating apparently doesn't matter -- even where it has worn off, continuity with the internal pin is OK. But after the second cleaning, that pin wasn't rebounding quite as high as the other pins (0.5mm shorter). Additional alcohol and working the pin down/up with tweezers, back to full height.
that happened to me too...
what firmware do you use?

Spilled soda and usbc port!

So last night like an idiot I spilled a can of soda on the table my phone was sitting on. The soda splashed just a tiny bit onto the bottom of my phone screen, only a drop or two.
Ever since I keep randomly getting moisture detected, when I doesn't detect moisture it displays funny behaviour also randomly. After unplugging charger for instance it will there and just loop the doo doo sound it makes when plugging in the charger until I turn it off and reboot. Also detects my charger that wasn't detected as a fast charger before as a fast charger, again randomly goes back and forth between regular and fast charge mode.
Obviously got some into the port and left sticky residue behind even if its already dry.
How can I get this out, is rubbing alcohol safe to try to resolve it?
Put a little isopropyl alcohol and clean it with a thin piece of a cloth.
try cleaning it with tooth brush and 90%+ alcohol it should solve the problem
The residue of the soda is causing this.
Rinse the port with some water...
