Recently my phone was damaged through the charging port due to moisture. In the morning I typically bring my phone with me to keep track of time. Usually I would blow out the port to remove water but when I plugged in my charging cable later in the day, the connector got so hot it burned the tip of my fingers and melted some of its internal plastic into the port. So now I can only charge wirelessly. I'm thinking what if I purchase a magnetic connector and leave it there permanently and seal the gap with some metal purpose caulking. In the case I get moisture on the contacts I can just wipe it off.
Immediately I want to say it's a very bad idea, mainly because most caulking has an off-gassing effect that could be damaging to the sensitive innards of a phone. But! I'm surely willing to be impressed. Be leery not to get any on the actual contacts and use it sparingly, you may be OK.

When I get my phone back I'll post some pictures.

Typically the issue on our phones is that the magnetic port pulls out after a lot of use. I had this and I superglued that sucker back in. Now, I have a whole new issue. One of the little nubs with the metal contact completely came off! I seriously have no idea how they could have happened. It's hard to describe but I'll take a picture when I can to show this. The annoying thing is that I superglued this one in very well. I would have to seriously risk breaking more things to pry this one off to replace it! Despite no update to marshmallow (D6616) and these crazy build issues I still don't see a compelling new phone to replace this one -_-.
Pics. Initially, the little metal circle was gone. I scraped away the rest of the little black circle to expose the little bit of metal that is still sticking out. I can still use the magnetic charging port as long as I carefully attach it in a way that the little metal piece makes contact with the charger.
Please make a photo of your magnetic cable connector too
When the microphone of my z3 broke, the service changed all the frame of my mobile.
i was so happy, my old magnetic charging port was very worn out (almost like your picture)
I blame users using cheap magnetic cables bought from ebay and amazon because of this. Magnets can be super strong, strong, medium, and weak. Mine has been fine since owning the phone Dec 2014. I use the Sony magnetic dock and always charge on it. The only problem I have is that it needs a backbone to charge because DUE TO MY FAULT, when the phone dropped, it bent the trim area of the magnetic port.
People always need to point fingers at everyone besides themselves.

By the condition of your phone from the pics you posted I'm not surprised. I have 2 magnetic chargers and non have this issue. The magnets are relatively weak - just strong enough to hold the cable to th phone while moving it around - and I've not experienced any issues although my charging port doesn't look near as haggard as the ops.

I use the magnector connector which is what initially caused my magnetic port to pull out. My magnetic port looks all jacked up because I superglued the port back in but got messy with the glue and had to scrape some off. Anyways despite how messed up my magnetic port looks, the rest of my phone is actually pretty much in new condition. I have had it in a case all its life and a glass screen protector.
Ive gotten this tablet wet a few times, (Tab A, T510 2019 10.1) nothing serious, not underwater. this time i had it next to shower, and just got a little water on the screen. I wiped it off and used it for about 1/2 hour, then suddenly the bottom 3rd of the screen pixelated and it flickered. That only lasted a few seconds, then the screen lost some brightness, just looked a little gray.
So i powered it down. Since then, screen is black when it boots, but it does beep with the moisture detected error when I plug in charger. i have been able to power it off and on and get that moisture error, but black screen. when I plug it into PC, i get the Windows code 43 hardware error, device not recognized.
I don't have much hope for it, but thought I'd check here.
Thanks!
Disconnect the battery NOW.
Allow to dry a in warm dry room with a fan on it, with the back panel removed for at least a week.
Disassemble as much as you can easily do to speed drying.
If it's an AMOLED display there's more you can do.
ok, thanks! its TFT-LCD. I already have it apart, and just disconnected battery again. i will put it in a dry upstairs window with plenty of sun.

Don't fry it... sheild the LCD from direct sunlight by putting it down face first.
Put a fan on it too.
Disconnecting any ribbon cable ends that got exposed may help. However ESD becomes a potential issue as out of circuit components especially the mobo are suspectable to ESD damage.
Because of the LCD you can't use anhydrous isopropyl alcohol as a drying agent; it will poison the display.
You may get lucky particularly if you see no visible corrosion damage on the power sections of the mobo. IP68 means it might resist water, I never trust it. Useful to keep dust out though.

ok, thanks again. I have it face down with a fan on it, and i put it in a dry place that doesn't get much direct sunlight.
I really didn't think it got very wet at all. I definitely can't see any corrosion damage. The moisture detection on some Samsungs is very sensitive. Mine even goes off in the summer solely due to high humidity.

You're welcome.
It's safe to put it in sunlight just not with LCD facing it. As long as it's cool enough to touch it won't harm it.
Most at risk are the powerc circuits carrying higher current loads which can accelerate corrosion damage. Or it may simply keep the signal tranfer on data circuits from working with no damage. The faster you pull the battery then dry it, generally the better the outcome.
I dropped my Galaxy Buds case in a cup of coffee (cream&sugar) over 3 years ago. Open it immediately, flushed with RO water, then anhydrous isopropyl alcohol, dried for a day, then drank the coffee. It still works today.
Hi !
My K20 is dead now, even if I tested with the original battery which worked.
Please look at the photo.
It displays that at switch on, or nothing.
But I have a vibration.
Thanks for your help.

I had the same problem on my K30 after a screen replacement.
I don't understand why I can't power on more my phone since I unplug then replug the battery.
Loose or damaged ribbon connector or cable.
Damaged display matrix or mobo.
Out of circuit displays and mobos are suspectable to ESD damage on their I/O's as these are not ESD harden.
Each time, flex cables replaced.
Last time, I ordered a new mobo, and it was ok, but next battery disconnect and reconnect, same problem, every time.
3 new mobos for the K20 !!
I do something wrong, and I need to know what !

ESD... observe ESD protocols. Raise room humidity to at least 50%. Use a ESD mat or a bare wooden surface. Use a ESD wrist strap that's earth grounded. Wear cotton clothing. Avoid generation of static as much as possible.
I've seen techs grossly mishandled mobos in terms of no ESD protection and get away with it.
Your mobo maybe more sensitive. If you can sense the presence of static electricity it's already way more than enough to do real damage. You become aware of ESD at around 1000 volts; I/O's may only tolerate 25 volts or less of over voltage.
Make sure you reassemble it exactly as it was. Be very careful not to damage connector pins or the cables. Take your time and do it right.
Impossible.
I repair phones for a long time, and I caused an electric damage on an iphone the first time, because I unpluged the battery flex connector with a metalic hook !
Since, ESD wrist strap and never other damage.
And when it happens, it appeatrs a significative spark.
Then the problem isn't that.

Very possible. ESD damage can happen even with what you thought were adequate safeguards. Best not to touch the I/O's at all.
You can't sense 200 volts of static but simply rubbing two pieces of paper together can generate well over 400 volts. Even anti static plastics generate static, the charge dissipates faster though. I have a 3M ESD meter and played around with it quit a bit... it takes very little static electricity to blow through the insulator of a MOS gate.
Relative humidity is the most important factor to limiting ESD by increasing the static bleed off rate. I used conductive flooring in my shop as well. The whole work bench was ESD matted/earth grounded. Earth grounded static safe soldering irons. I was careful to discharge myself after moving around before touching sensitive components.
Then it's sure my mobo is dead ?
And very curious I have the same issue each time I open this phone, and never others...

It could be you missed something when you reassembled it. Sometimes a longer screw or the frame are used as a ground return or otherwise missing ground pathway. If there was battery swelling that could have damaged the display or if the battery removal was too forceful.
Connector pins and ribbon cables are fragile if not properly handled.
It could be a few things causing this.
Hi all. My trusty A40 had a little mishap at the toilet (!) and drowned. I gave it a rinse with alcohol and dried it for days in 40C ovens etc. but no life was recovered. A few days ago I decided to try charging it anyway and nothing happened... then this morning my old alarm went off! The screen is still completely dead, and I didn't notice any vibration but I always had that turned off. When I plug it in and out with the USB cable it makes the correct beeps. I can even snooze that alarm with the power button and turn it off with volume down.
When I connect it to my PC though I don't see any drive come up, I guess it doesn't default to USB file transfer so maybe this isn't a surprise.
So is my phone alive inside and just has a completely dead screen? The alcohol has conveniently taken the back off by dissolving the glue. Also, I've already got a new Redmi Note 11 so I'm happy to tinker with this phone and I've replaced screens before no problem.
Is this phone worth buying a new screen for do you all think or would that be a total waster of $35?
Thanks!
(PS: sorry if not in correct forum here, not sure which one is most appropriate for hardware / repair issues)
Wrong. You may still be able to save it...
Pull the back cover and disconnect the battery asap. Allow to dry completely before powering up. Fan blowing on it with the phone on it's side in a very warm room for at least a couple days.
The mobo power section or the soc are the most likely areas to fail from corrosion. Possible the connectors are still retaining brown water
Do Not use anhydrous isopropyl alcohol as a drying agent if it has an LCD as it will poison it.

Thanks but I've already completed the drying. The CPU is working in there, in fact when I put in a SIM it will even ring when I phone it. I'm just wondering if I can be 100% sure everything is OK apart from the screen? Is there anything else I can check?

If it's dry and still malfunctioning the damage is likely to the mobo, is permanent and will be progressive. Corrosion never sleeps.
You can disassemble and check the ribbon cable pins going to the display for moisture and/or corrosion damage. The mobo power section and the BGA chipsets* (can't see the damage as the contacts are under the chip) are the most likely to be damaged.
With water exposure time is of the essence. You might save the device if you're fast enough and do the right things. Salt water is sure death.
* you sure it's dry?!! BGA chipset's don't have airflow around the pins. Any water under the chipset will also be retained by capillary action...

I submerged the whole thing in alcohol and then dried it at 50C for 72 hours. Everything I can test works perfectly (including ringing when called) but the screen is totally dead. I cleaned that socket but still nothing.
Is it possible the water/alcohol damaged the screen and not the motherboard? Sound unlikely but that's what they symptoms indicate.
So is it worth a bet on fixing with a $30 new screen or not do you think?

I think it's the mobo but you're holding it. I don't know how suspectable the the display is to water damage. Did you use anhydrous isopropyl alcohol?

All I could find was 100% ethanol I'm afraid and only realised the FAQs saying "alcohol" were talking about isopropanol after I'd finished. Isn't ethanol also used for mobo cleaning? Maybe that destroyed the screen though.

Water can damage AMOLED displays as well it seems. Best to keep all solvents away from the display. Methanol alcohol should never be used.
Ethanol not sure about.

OK I think then I'll shoot the moon and buy a replacement screen... would be a terrible waste to throw this phone out if that's all that's wrong.
Plus we would now know that ethanol is OK for phone motherboards, plus it takes the glue off the back of a Samsung A40!

Use anhydrous (preferably 96% minimum 93%) isopropyl alcohol.
I wouldn't go too nuts trying to save it due the price point and especially the fact it has known water damage. Buying a used one in good condition be a viable option if you really like that model.

I've just notices that with this model there is a pretty hefty flex between the top and bottoms boards with a connector on each end. This must also carry screen data so I'll give that a good clean out.
Second hand AMOLEDs are impossible to find for the A40, they all have horrible burn in.
I'm going to get the INCELL LCD version already in a new front frame and go from there. Should still be a decent back up phone.
And the fun of fixing it is what it's all about anyway, right? :-D
You grossly underestimate the corrosion process that's likely been initiated. I'm not so optimistic about it ever being reliable again.
I can understand corrosion while the phone is wet... not after it's been soaked in alcohol and completely dried. The process doesn't continue.
I'm going to guess it's the screen only that's broken as I see no other issues... I bought a cheap LCD replacement already in a new frame for $30.
Let's see how it goes.

Yes, yes it does. Most don't understand how insidious it is. The oxides formed are insoluble in water and alcohols. Many are hygroscopic and attract moisture, then you know what happens...
This is the same reason you never buy a flood damaged car. Even if everything is working it will start to fail sure as the sun rises in the morning.
Sometimes if you pull the battery before the flooding it can be saved... sometimes. Always check for signs of water damage when buying a vehicle. EV's just burn to the ground when water damaged
Energized circuits greatly exacerbate and accelerate the corrosion process. You see the results. The future is uncertain for that phone but it will likely eventually fail from that one prolonged exposure.

OK so the new screen eventually arrived and I turned on the phone then plugged in the new screen... nothing. But I guess you have to plug in the screen and then turn it on, but that seems to be impossible with the A40 where you need to attach the middle frame for to use power/volume, and that blocks the screen connector.
Is there some way to bridge those little spring contacts on the PCB to reproduce a power on signal? Otherwise I'll just have to do the whole replacement process and see what happens at the end!
Just as well there's holidays coming.

i do not know, sorry, never opened my a40, still using it right now
I received an s8 from my friend, and upon inspecting it, it did not turn on. No vibrations, no leds, nothing. It appears to be water damaged (indicators were red) however after opening it up, the motherboard seems to be in good condition with no burn makrs or corrosion. The charging port was a bit corroded but it cleaned up well after using some alcohol.
The battery smelled of nail polish remover which i heard is a sign of a leaking battery.
With the phone opened up, And when connected to the charger (battery and other components connected as well) the cpu part of the board got warm making me believe the motherboard is indeed working. However I'm confused as there's no vibration, display, or led lights)
Just to be safe I cleaned the entire thing with 99% alcohol and let it dry.
If anyone has any ideas on how to get it started, please let me know
The battery electrolyte has a strange cherry acetone sort of smell. Once you smell it you won't forget it.
Replace the battery. If that fails inspect all connector contacts for corrosion. Consider replacing the port daughter board. Water damage is insidious especially if not addressed immediately. It may not be salvageable at this point...

Alright so the battery might be an issue. I think the charging daughter board is fine since the motherboard was getting warm where the CPU is located when i plugged in the charger. Why might it not be too salvageable?

What part of insidious don't you understand?
If the battery had been pulled immediately and then the phone dried out it may have been alright. Don't count on it though. You're a bit beyond that.
The SOC is a BGA chipset meaning all its contacts are hidden underneath it... where water can be trap and corrode them and the pcb traces. No way to clean that short of hot air removal. In a short amount of time water can destroy a phone if it's battery is connected.
