Recently my Samsung Galaxy Note 9 has been saying that there is water or moisture in the charging/USB-C port, when I know that there is no moisture in it. I've seen others complaining of the same thing, but here's the catch...
Since this has started happening, it has been getting worse -- it used to charge fine while the phone was off, but now it still says moisture detected even when the phone is powered off. Also, it has literally melted two of my charging cables. Literally. The phone has become so hot that it burns my fingers and causes blistering. Obviously when this happens I unplug the phone immediately, and when I do, the charging cable is always melted and physically deformed, when it never used to be. I have tried charging cables from many different manufacturers, and the same issue still occurs.
For now it does not seem to be melting any of my charging cables anymore, but it is still not charging due to some form of moisture being detected in the charging port.
I have a warranty through AT&T, but I still have to pay for the repair according to them, so I'm wondering if there is a serious issue with the phone or if there is some kind of workaround.
Thank you.

I did a quick search and sure as ****, the phone is using some form of measuring electrical resistance to detect moisture. Just because its saying moisture doesn't mean that its moisture though, as its not literally a water detector. Given that your phone is producing excessive heat and is melting charging cables, im going to put my life savings on dirt/debris in the charge port causing electrical resistance and triggering the moisture warning.

That's really interesting. I had no idea that was a thing. I'll keep this in mind.
STOP CHARGING YOUR PHONE, IT COULD CAUSE A FIRE.

I haven't charged it since -- I've stowed it away in a cool place and haven't touched it since trying multiple cables and getting the same result. I figured it'd be best to leave it alone until I figure out what the cause may be.
Call At&t and get an estimate for charge port replacement, and then do the same for a local repair shop, decide which is the better option.

I think I will do this and find out what AT&T wants to charge me. If it's not within my budget, I'll look into it and do it myself before I would trust any of the local repair shops here.
Anyway, thanks for your help, and I'll take all of this into consideration. It is greatly appreciated.
My brother is having similar problem. So he is intelligently using wireless charging exclusively. He wants to continue that untill he figures out the solution
Same thing happened to my wife's S9. Kept saying moisture was detected in charging port. She had to use the wireless charger until I found a simple solution.
The reason was that the port had minute dust in it. I first cut a small piece of stiff plastic to a point (like a toothpick), then gently scraped around in the port to loosen up any larger bits of dust/dirt, then blew through a straw in short spurts (you could also invest in a can of compressed air too for camera lenses). Problem went away.

I got a ton of clay in my charging port. I never got the moisture detection popup but I wasn't even able to get the charger in the port.
You can also use pure 99% isopropyl alcohol to Clea. Out ports. Justbe sure that the pho e is off, and be sure to evacuate any alcohol in the ports immediately after applying them to the port to prevent the alcohol from seeping in the phone. Reason being you can ruin the water seal rating, but with a sharp objects you run the risk of damaging the port itself.
You can just let the phone with for 5 minutes or use a blow dryer to evaporate the remaining isopropyl away.

Thanks, but if you're careful with the scraping, as I am, no damage is done.
Also, even salt water can damage the seals, so I'm not too keen on introducing any chemical into the port. But I guess whatever works, works.
If your port is clean and you're still getting the moisture message, please change your charge cable. The moisture detected feature works by two specific pins being grounded out, both in your charge port and the plug on the connector; which could cause inefficient charging to occur. Think connect, disconnect, connect, disconnect, like the older devices used to do until the battery would eventually overheat and...explode.
By the way, those contact thermals are indeed metal, so eventually salt water will rust it's way into your phone.
Mine started to complain about moisture in the USB port about 2 weeks ago, it was raining for an hour but the phone was never exposed to direct rain water.
I left it alone for about 30 mins and the alert went away. So far so good. Later I discovered that even though I was using the original Fast charger, it will fast charge for 2 seconds then switch to normal charging.
That went on for about a week until on Monday it decided that it wont detect the USB charger any more. Not even normal charging. So I took it to a Samsung reseller, they confirmed it hasnt been in touch with water through the SIM tray, confirmed it's a defective USB port and sent it to Samsung Italia for repair.

Hey guys, two days ago I was using my s4 Active on the bathtub to test the Aqua mode on the camera. After that when I tried to charge it it wouldn't charge. I've been using different batteries and an external charger to keep it running before going to my provider and check if the warranty will cover it.
Yesterday I read that alcohol may work to fix water damage, so I poured some 80% rubbing alcohol onto the usb port and basically the entire back of the phone. I let it dry in the sun for about 20 minutes and when I turned it on the screen was completely ****ed up, there are like blubs under it, as if the alcohol got under the screen, i can barely see it and now the touch capability won't work. Is there any way to fix this or is my phone lost?

You did what? I....I just..........just send it in for warranty replacement, say it is water damaged, and leave it at that.
By chance, did you leave the battery in it when you did this? If so, take Devo's advice and pray for the best because that's your only hope. ANY liquid inside a phone with a battery in it will short things out. Even with the battery removed there are still capacitors inside that hold small amounts of electricity for a period that could be damaged by liquid. Not a very good idea.
Hello everyone
So a couple weeks ago I took a unexpected swim with my Nexus 6 in my pocket, and haven't gotten it to work since. When I got out I immediately took the phone out of my pocket and turned it off, only to have it boot back into fastboot a few seconds later, turn off, boot to fastboot, and turn of again. It did this several times till it just stayed off. I took it apart, dried it, and cleaned it in Isopropyl alcohol and tried to turn it on but got no response no matter what I did. :crying:
I would consider it fried except whenever I plug it into my charger, the charging icon comes up like normal and even does the battery filling up animation. I replaced the power/volume button strip inside the phone hoping that it was the only problem, but it still would't turn on. I haven't replaced the battery yet because the charging animation shows it's holding charge, but loosing 40ish% after a week and a half of sitting there.
So is there something else I can do, or is it fried? I'm probably going to get a new battery to see if that improves anything, but I honestly don't know what more to do. If anyone has any ideas, I'd love to hear them.
Thanks in advance!
It's fried. Best you can do is send to shop and see if they can salvage it.
Alright, I'll guess I'll have to do that. Thank you for your reply.
I would like to share photos of my phone and seee if anyone vcan help, my situation is kind of similar. I tried to charge after to days of silica drying and cleaning with IPA.
I thin the connection around the battery area isn't secure. Is there a glue that i could buy?
The only thing a shop may do, is give it a bath in a ultrasonic machine, and bake the board. Try a new battery, internal batteries never do well in WD.

How about sticking the charging coil to the new battery? What type of adhesive is needed?

You may still have enough adhesive left over on the coil to stick it to it. Otherwise it doesn't matter much, as long as its connected and not crazy loose, the frame will hold it in place.

I got it kind of working, but the sound is fuzzy and the screen is flickering a little.
I'm missing some screws, so I'll need to buy some new ones.
T3/M3 torx screws, 2mm/3mm height/diameter?
Hiya
I seem to have a quirky moisture issue that appears the opposite to what people usually experience:
My phone will charge while powered on but with no fast charge.
If I power it off it and try charge it, it will say moisture detected.
I have tried:
The fast charge issue appeared while on holiday in a hot and humid environment, but I never tried turning off and charging during my holiday (just wanted to keep it working before i got home)
Drying the phone with a cool hairdryer
Left in bowl of rice overnight
resetting with cable plugged in
clearing the cache partition
etc etc
Any ideas what would make these two symptoms show up?
Well if you didn't put it in the water or a wet place where it could get some moister I would say... :
Take it to Samsung could be a problem with the phone itself.
Buy a wireless charger and charge it that way should be better.
it has definitely been in water before but definitely not outside of operating conditions (no deeper than 1.5m in fresh water and no great pressure applied). Always rinsed with fresh water straight away if it was in contact with any salt water.
The water damage indicator in the sim card tray still has nice crisp crosses on it so i don't think there has been any significant ingress of water into the phone otherwise this would be all red.
Just can't figure out why it would charge while powered on but not charge while it is off...
Fixed. Must have really got some persistent moisture stuck in there. Powered off and put in a drying oven at work and gave it a blow dry. Seems to be all good now. Might keep this one away from water for the foreseeable future haha
There's a lake 20 ft in front of my house and my phone's been in it a few times and never a problem... Blow out the charging port and be done with it.
A good friend has one and went to Florida and had the same issue, the only difference is the salt water. He ended up sending it in and they sent him a new one no charge...

Certain particles of debris can cross your pins which is what the device uses to detect moisture. If certain pins ground, your device will state it detects water.:good:

Maybe there was some sand stuck in there or something too
I cracked my screen a while ago and just got the time to do the install, but as some of you may know the adhesive holding this turd together is very tough. After blasting with a hair dryer and buying an automotive suction cup I finally got the glass off but it cracked too bad to be reused. I cant do anything with the device now. I've held all buttons for a restart but the broken pixels light up for a split second and then it vibrates for a quick second. as i continue to hold it runs through that process over and over. Even plugging it in to the wall I cant even get a charge light. The only cause i could think of is too much heat. i replaced the screen on a note 5 with no issues. It just makes no sense that it doesn't do anything from peeling the rear glass off. Unfortunately I'm at the parents house where I'm the only android user so i cant plug into a PC as i have the 2 sided typeC cable.
Any Ideas?? As I'm Stumped. And to top it off my spare phone an unlocked Pixel 2 is having the No Sim issue.... Fun times.... It just finished the factory reset and still wont detect my Verizon SIM or ATT. So that's cool, haha.
Thanks for the help. Much appreciate2

Stupid question did you reconnect the fingerprint sensor back in? It might need that to be connected to work.
Recheck all the connections again and ribbon cables for any damage maybe it got loose or heat damaged or cut.

Yes its been plugged in and the only thing i damaged was the foam on top of the lock button but its barely peeled back. no visible damage to the cable its self. and with the back cover the only part i took off the only exposed cable is really the fingerprint scanner. The scanner does though have some visible heat damage. there's little spots on it that wasn't there before. I think that's the cause of the problem.
could it be possible that i overheated the battery and now the device is in some kind of protection mode? the device could be thinking that it could catch fire or something? I know that Li-on batteries are pretty fragile to temperature.

If you have a multimeter you can check the battery voltage. If you have voltage then it should be okay but maybe the life of it won't be as long as before. Does the phone charge when you plug it in?
The fingerprint sensor might be the problem. I would replace it as with the battery as well.
Best bet have a Samsung service center look at it, it might be something else.
Good luck with it hope you get it figured out!

good thinking on throwing a meter on it. will do that when i get home. it doesn't charge or do anything when plugging into a computer or the wall. any idea what the voltage should be on the battery? is there anywhere i can get values like that for different components of the device? thanks

Battery specs should be 4000 mah, 15.4 Wh and 3.85 V.
Even though it will show voltage it might not have enough amperage to run. So might check for amperage as well.
Might want to hook up a light circuit to the battery and place the meter in between the + battery to + side of light (meaning the same line) to measure amps.
If it doesn't charge from the wall might as well replace the battery.
If that doesn't work most likely a dead phone (motherboard).
For any voltage values for the motherboard, sorry no idea if you can find that info.
You've been quite the help Blue. Thank you so much. Will be home tmrw and will check on the device. I'll be sure to come back with findings to return the favor. Thanks again! Hope you had a good holiday and Happy New Year!
Hi all,
I want to start giving the old smartphones that keep accumulating in our family a second life - which primarily means replacing aged batteries.
I actually want to use my S7 as a bike computer with the Komoot app, but decided to get some practice on my wife's old S6 Edge, which conveniently partially disassembled itself (bloated battery had opened the back cover).
So I got myself a spare battery and proceeded with the disassembly. Disconnecting all connectors, replacing the battery, reconnecting everything, and putting back the 13 screws that connect the frame to the display all worked ok, and the device would start up.
Alas, there are now a few glitches:
- the device feels quite slow (at least according to my wife... but maybe that is just subjective, now being used to much more modern devices)
- the device gets really warm (primarily on the middle of the right side, i.e. where the main board is located), even without any apps running, the battery also drains quite fast
- the left touch button (which on this device brings up the "task manager"/"app switcher") does not work. The right touch button ("back") works ok, as does the home button.
Everything else seems to work fine.
I disassembled everything twice, cleaned all connectors with alcohol, reassembled, same result. All connectors appear to be properly connected.
Any idea what could have gone wrong?
Needless to say, with that not-so-great result of my first repair attempts, I hesitate to work on anything more valuable than the S6...
Any hints welcome.
Regards
G
Welcome to XDA.
A connector pin may have been be damaged, inspect.
Do a factory reset and see what you got.
If that fails the mobo may have been damaged. Out of circuit they are suspectable to ESD damage. ESD protocols should be followed when doing repairs. At the very least raised the RH to 50% in the room.

It may not be your fault
The battery on my S7 swelled up a bit, so I got a new battery fitted, the shop had problems with the phone overheating so needed further testing. They had to replace the charging chip due to the battery swelling.

I was doing this on an ESD-safe matt, so that should be fine. Visually, the connectors are ok... but considering how small they are, I would probably need to check with a microscope (which I don't have... but I could try my macro lens.
There are two cable connectors with only two pins each (look a bit like mini koax connectors). The connect the charging board which also has the electronics for the touch buttons to the mobo. One appeared to have been squeezed, probably by the bloated battery. So I measured conductivity with a volt meter, they measured ok.
I guess I will write the device off... not worth to invest in more spare parts.
The S7, which I still like a lot , is a different thing. Would hate to break this, but the battery is nearly dead and might bloat anyway sooner or later. So on to the next test subject for my repair skills. ;-)

Wear a wrist strap and make sure the room isn't dry. Wear cotton clothes. Static electricity is omnipresent. Nonconductive plastics are can build up a charge, even paper. Keeping the relative humidity above 40% is very important; just boil some water in the room if needed.
2-3x stereo magnification Optivisor probably do it. Very handy for detailed work.
