SM-T590 Moisture Warning While Charging Switched Off - Samsung Galaxy Tab A series Questions & Answers

Has anyone had any issues with moisture warnings while charging the tablet switched off? It doesn't come up with any errors while the tablet is on and running. Things I've tried is a factory reset from recovery mode, drying the usb port with a hair drier and chucking it in some rice as well! I'm confident the port is clean and dry and I've also tried different chargers and cables.

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

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...

Warp Charge is not working

Hi All,
I'm using Oneplus 8 pro. Suddenly while charging my phone I can clearly see that Warp charge is not working. It is taking time to charge my phone. Earlier warp charge was working fine. Can anyone help me on resolving this issue?
Regards,
walis
turn off optimized charging.
i do that bro but same problem
Try different cables and charge blocks. Maybe one of yours is worn out.
Clean your USB Port -
Charging problems may be caused by dust blocking the connections in the charging port. Dirt, dust, and lint can get between the metal pins of the charging cable and charging port, preventing electricity from flowing. Clean your connection port with a toothpick to remove dust.

2017 Fire HD 10 Moisture Detection, how to make it go away so I can charge?

I have a 32 GB version that I bought off of eBay.
It's been a few days and I am getting this moisture detection warning and am not being allowed to charge my tablet.
I've done the trick where you let the battery drain and die then plug it in and then shut it off the charge. I leave it for the day but it will only charge to 7% or something like that.
Is this tablet basically useless now? I've done a search for this topic and it seems many people have had the problem. Trouble is, there is no one universal solution.
Anyone?
The moisture detection warning has happened to me twice. Both times it went away after I applied suction to clear out any fluff (from the tablet's USB-C port and the plug of the charging cable), using the nozzle of a vaccum cleaner.
Ways to fix Moisture Detection warning:
1. Use different charging bricks and cables.
2. Use a vacuum cleaner or compressed air to dry and clean out the charging port.
3. If didn't work, charge it directly to the tablet's battery using the TP4056 USB charging module from Amazon or eBay (which requires basic soldering skills).
Amazon let me exchange it
