During past few days, my S7 has suddenly started reporting moisture detected - check USB port error whenever I try to charge it, although the phone has never been exposed to water. Sometimes it will allow to charge a bit, but will soon revert to that error. In some rare occasions it will Fast charge a bit, but I have to re-plug USB several times to get it, otherwise it will just be slow charge. The situation has been only worsening lately.
Rebooting doesn't help, nor does shutting off and on. It's the same with other USB chargers and cables. I have already try to blow in with hair dryer and compressed air, which helps a bit temporarily, but not much.
What to do? Sending it to the repair service is the last resort, because I feel it just won't be waterproof anymore after I receive it back. There's also a major problem that our official local service is well-known of cheating and fraudulence, because they just always say that the phone has been exposed to the water and will just send pictures of some other oxidized motherboards or either simply mark the moisture detectors.

Hi mate
there is a safe check for moisture on the phone , try leaving with some dry rice overnight or better yet use some silica gel
Check this thread some people had similar issues
http://forum.xda-developers.com/s7-edge/help/moisture-detected-t3328011
Also check this video it may give you some hints to determine if water got inside
https://www.youtube.com/watch?v=B4KOg7g1zfE
none of that helps. I have the same problem. Have not gotten phone wet, but constant moisture detected.
I live in S FL and had the problem a handfull of times. I am now in a town ON the ocean, as well as being hot, and have the problem most of the time (of a week of being here I was able to charge it twice)
again. phone has not gotten wet.
wonder if high humidity content in the air is causing it.
Mine started giving me this message as soon as I returned from a week in Honolulu. I live in a much drier climate. I brought it back to my carrier and they sent it away. It was returned "repaired" yesterday and everything seemed fine but this morning it started again (even after I rebooted). The phone was nowhere here water so I'm not sure if it's a humidity thing. The moisture detector is also unmarked.
For me this worked:
https://galaxy-tipps.de/samsung-galaxy-s7-feuchtigkeit-wurde-erkannt-akku-laedt-nicht/
It's in german. Basically it says the following:
If you get the "moisture detected" message though the port is dry, reboot your device into "Safe Mode" by holding volume down pressed while boot.
Then reboot device in normal mode.
Same issue. Safe Mode didn't help.

I'm having the exact same issue, and rebooting into Safe Mode didn't help.
Anyone knows if it's absolutely necessary to have the USB port replaced? The issue with that is that it is very very complicated, if not impossible to replace the USB port of the S7 without damaging the screen. Therefore, to replace the USB port you also need to replace the screen, which sucks.
Any help?
I just hit the same problem. The phone would complain about the moisture in the USB port, but the phone was never wet. I went to the Sprint store, they tested the phone with wireless charger which worked. So I assumed that there is something in the USB port that holds moisture. I got a wooden toothpick and cleaned the port. Right after I did this, my phone started charging.

Thank the heavens this works on the galaxy S8+
Mine was doing yesterday the same. I have rebooted it and now it doesn't even detect the charger. Nothing happens when i plug the cable. I used a bit water just to clean the phone and was drying whole night. Is this something that guarantee will cover?

Probably not as the phone is water resistant doesn't mean waterproof so it's not covered....Sony changed its campaign from waterproof to ip68 water resistant due to backlash from people going on major dives with their phones and trying to get the phone replaced under warranty
It's already old thread. So how did you manage to make it working again? I'm struggling with it already over 24 hours and no success. Hair dryer helps for few mins, i'm able to charge it as long as it is still hot after drying. But then the error comes back and no wired charging possible.

Holding the volume down button while powering on puts it into safe mode which seems to have solved the issue on the S8+ after that you can put your phone back into regular mode and charging should work as normal.
ok, after 3 days my moisture finally disappeared and i'm able to charge my phone normally, even with quick charging.

Haha I rinsed my USB port out and next day it worked fine......
Apparently the problem still persisted. I uninstalled a bunch of apps and it's no longer an issue seems that some apps set off the sensor for who knows what reason.

No, flashing stock with ODIN will not trip KNOX, but unlikely to solve a moisture detection error either

Hi
some people had that problem and going into safe mode and re start it in normal mode helped....
Turn on and use safe mode
Turn the device off.
Press and hold the Power key past the Samsung Galaxy S7 edge screen.
When "SAMSUNG" appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see Safe Mode.
Uninstall apps that are causing a problem.
Turn off safe mode
Press and hold the Power key.
Tap Restart.
Worth trying
Used safe mode but no use
I used safe mode but moisture detected still not going away. Please help. My phone is not wet.

I got my sgs2 about a month ago and its been like a dream, battery lasts for a long time phone runs ultra smoothly no glitches and nothing weird has been happening, but these last few days its just been really weird.
1) it started randomly going into driving mode, i dont even know how to activate it or what it does, but i think its draining my battery
2)When i was watching a tv show on my phone it thought that there was an hdmi cable connected and wouldnt let me hear anything through my headphones. i exited it several times but it still though there was a cable connected. Then i went straight home and quit it from the task manager and it worked with the headphines but that might have been a coincidence.
3)When i connect the charger it takes a while to realize that its charging and sometimes stops charging and says that the battery is too hot or too cold but when i feel the phone it feels completely normal.
4)When i connect the usb cable, other than taking a while to realize that its connected to a charger it doesnt realize that its a usb so i cant transfer files with my computer which i do often
5)I pressed home before and it took me to some sort of clock which i imagine is for a dock but i have no such thing
6) Even after using the phone for a while and using several apps the android os has used 59% of my battery, when usually its the display that uses about 30 or 40%
none of these things had happened before and now they randomly started all at once, i havent downloaded any shady apps so i doubt its malware
any ideas?
thanks
Are you using a stock firmware or custom?
Have you tried resetting back to factory default?

seems like majority of your problems are linked with the micro USB port, try resetting your phone and see if that helps. This is weird though.
It happened once to me on my sgs but that was because I inserted the charging pin without realising it was wet but it went back to normal a few days later and I changed my charger.
i was also starting to think it would be a micro usb problem,
would a factory reset fix it?
if so how would i back up my apps so that i have the same apps with the same progress on them, is it even possible?
or should i just wait and see if it goes back to normal?
I am also having this issue now. I've tried a factory reset with no effect. The phone is now largely unusable. Did you get a resolution? If so, how?
im having the same problem too .. wish it's just a software issue!!
the problem solved itself after a couple of days, i took out the battery and left the phone alone for about a day and after it worked fine again, not sure if it was the time or leaving it without battery but its working normally again
I'm having this exact problem - phone switches into driving mode, then says MTP is connected - then it switcheds to a strange lock-screen I have never sen before. It's really strange. I flashed a nandroid backup from a few months back and still the problem is there. I'd flash back to stock and send it in - but I can't connect to Odin via USB because of the problem. Is there anyway to convert a Stock rom to a CWM flashable file?
I'm desperate to get this sorted.
Experiencing the same. Has anyone a proven solution for this?
My phone, sorted itself out - should I say my wife sorted it out - by mistake. What I think she done was hold down the home button, and then pressed the power off button together and held them untill the phone switched off. When my phone came back on again - she had somehow removed the -Exclamation Triangle of the kernel counter and removed the problems from this post - that I'd been experiencing for abouyt 5 months prior.
Go figure - I now have a SGS2 that works beautifully again and has also had any kernel counter and Custom Rom flashing notifications removed altogether. I wish I knew why this worked, as I'm sure their are many who would like to remove the Triangle without a jig.
The other option that seeemd to work for other people was to clean the MicroUSB port of the device with a dry, clean toothbrush - though this did nothing for my problem. Good luck -I know how frustrating it is.
Help Please
Guys, I am Facing the EXACT same problem.
1.Driving mode on/off automatically
2.Showing a lockscreen which shouldn't have existed on this planet.
3.Hanging up unconditionally. Have to restart phone.
4.Sudden "mtp connections" and because of that "Media Scanner"
I own a Galaxy note just 1 month old! I was so angry that i wanted to sell this. But i couldn't adapt to any other smaller screens so, guess ill try fixing this.
1.It definitely is something related to usb port (Since i cannot charge my phone, i use an external charger)
2.Took my beloved to a samsung service centre, they said phone is waterlogged and showed me the motherboard, saying"IC MIGHT be damaged"
3.Cost for repair - $200
4.Cannot afford that. I am guessing they were bluffing cause i saw the shiniest motherboard ever
5.Please fix this, or ill be stuck with a Nokia 500 !!
6.I can, however afford changing the usb connector, anyone successful with that?
Edit: Did my homework and found out that its definitely a usb port problem. Solution:Clean the usb port. Ill try try it and get back to you ppl. Oh and about 20% of the world's population is facing the same problem.
Edit(2): SOLVED!!!
1. Turn Off phone
2. Remove battery.
3.Take a Brush with hard bristles(Toothbrush/Artist's Brush)
4.Take a pin.
5.Take your own sweet 15mins to perfectly clean the micro usb port using the brush. Nicely and Tidily, give all possible strokes to flawlessly remove any dirt in there.
4.Then take your pin(Be careful here) and gently insert it into the gap between that small metallic micro slab and the bottom part of the usb Connector and gently move it up, VERY GENTLY!!!
5.Clean the battery's charging plates using a cloth, i used my own T-Shirt.
6.Put battery in and REBOOT.
7.Clean the charging pin of the charger using the safety pin/Brush or both.
I have it on for 15mins and no problems. Removed and put the charger again and again, still no problem. After waiting for 1 week, i am able to charge it using its charger! Now lets see whether it lasts......:-/
Edit(3): So, my phone acted up again last night, with driving mode and car dock. I used the pin solution, No problem till now. its Peacefully charging. Bah! it really is annoying
Edit(4): Now, its been 24 hours since my last solution, and phone hasnt acted strange. I guess after another 12 hours ill rule out the permanent solution. Which i used.
same here
Well.. I'm having similar issue. Battery drain and random driving mode/voice search sometimes. It all started after last OTA update and rooting without changing a ROM to custom. I've clean out USB port and no result. Maybe it's time to scan system with AV or unroot device...

I had the same issues 2 weeks after i bought my galaxy s2. Took it to Samsung customer care and they replaced the micro usb port. Haven't had a single issue since.
PS: Try to dry out the port and the phone if it is a water logging issue. I used a hair drier to do that. Luckily the tab that indicates water damage hadn't changed colour.
Had same issue with my Samsung Galaxy Note - randomly going in and out of driving mode, used a dry, soft toothbrush to clean out the USB Charging port, so far so good.
Make sure to flick the bristles of the toothbrush back and forth with your thumb first as you might see a lot of dust fly off of it.
Don't use anything hard like a pin or needle as you might scratch the contacts.

It's just a software problem, the reasons might be:-
1) you might have opened and closed some huge apps randomly and very rudely..
2) You are low on space on the internal MMC Card
3) Your phone might be performing the restarting apps re scheduler
Solutions:-
1)Factory Data reset will not help as the cache section might be corrupt.. neither the android 3e will help...
2) a)Use odin and download the Latest firmware package from Sammobile's Website.
b) for tutorial on flashing, go http://forum.xda-developers.com/showthread.php?t=2488942.
c) Do not touch the phone after processes and restart was observed...
d) Again get into download mode and re flash the same Firmware again...
e) Restart the phone holding the HOME key, (it won't do anything by itself)
f) it will surely fix your Phone
3) Message me if any problem persists...

I registered on this forum just to say that this is a great solution. It looks like my phone is saved now
Hope it will not happen again.
Hello.
After falling to the ground with my S6 in my pocket I noticed it was off. At that time I thought I just ran out of battery even tho it didn't show the zero battery logo. After plugging the phone the battery logo showed and it started going from 0 to 94/95 in a matter of seconds (like 5% per second). I turned the phone on, it charged normally from 94 to 100 and after unplugging the charger the power was cut - immediately turned off.
It does this every time I plug it in: "charges" stupidly fast to 94%, turns ON and works normally until I disconnect the charger.
Do you guys know what the problem is? I find odd if the battery is dead because it went In for service 3 or 4 months ago and they replaced almost everything except screen, camera, back panel and frame. I would send it again to service but I rooted it so Knox is cracked.
Maybe because of the fall I took the battery cable was disconnected?
Thanks
Certainly sounds like a hardware issue because of the drop it took. Now it is charging but obviously erratically, could be the charging daughter board or the ic that needs replacing. Either way it needs to go in for repair, id try and get some quotes

The only way you'll know for sure if this is not a software issue is to factory reset or flash Stock firmware, it very well could a connection has come lose or some sort of damage to the charging part of board if you continue to have issues.
Sent to repair and they replaced the battery. Since I live in Europe Knox 0x1 wasn't an issue.
About a month ago I kept my s10e near an AC and a few moments later the phone alerted me with moisture detected in charging port. Since my phone wasn't charged much it got switched off in a while. For a week I tried troubleshooting with each and every method, later I got a wireless charger when nothing worked out for me. Its been more than a month now and it takes more than 3 hours to charge the phone and secondly I'm unable to connect the phone via a USB cable for any sort of backup if I want. Kindly help me with this, if we can permanently disable the moisture detected glitch or shall installing any custom rom override this problem ???
Try to reset the phone ?
I had exactly the same about a year ago. For my 10e it was a hardware error: a short circuit in the usb port. It was repaired under warranty. Since the port is part of the motherboard, the whole motherboard was replaced.
Tried to reset. Shall applying a custom rom help me get out of this?? Or can I permanently disable some software file which blocks the phone from getting charged during moisture detection.
Possibly, I didn't try as my S10e is a company phone and I didn't want to trip knox. I was tempted to install LineageOS but in the end I took my phone to the Samsung repair centre instead.
Thank you let me know if I can try any other options
Go to Settings > Apps, press 3-dot menu button in top right corner and press Show System Apps, go to Android System and clear cache. I used to get that error a couple of times a day, hasn't happened once since I did the above.
If you have corrosion in your charging port this won't work since that's a physical problem, but if it's a software hiccup this should take care of it.
Hello!
I recently tried to replace my LCD/Digitizer on my S6 edge SM-G925V. Everything went well...at least I thought. The display works great! However, I believe I have either a battery issue or a OS issue.
After I installed the new screen, I booted the phone up. It loaded up fine. I went to check to make sure every feature worked. I was playing music to test the speaker and the phone just restarted on its own. I found that to be odd, and so I tried again. Same thing. This is just a couple minutes into it turning on by the way. Sometimes it would take longer to restart than others, but it was generally in the same time frame. I did try other apps to see if maybe the music app was causing it to have issues. The phone would restart randomly regardless of what I was doing.
I first thought that maybe the battery wasn't charged up enough. I charged it some, but was still getting the same issue. I then went to try and boot into safe mode. Still the same issue was there. I tried resetting the phone, master resetting the phone, and also wiping the partition. The phone now boots to the Samsung screen, then goes to the Verizon screen and then reboots in a endless cycle.
So...it was booting correctly, but randomly restarting. NOW, it's not getting past the Verizon screen and rebooting.
I tried using Odin and resetting it using the latest software update. It would pass just fine. The phone would reboot then go to "Installing Updates". It would get to 32% then say "Erasing". It would reboot back to the Samsung screen and start the endless boot process again.
The one thing that Intrigued me and led me to trying to use Odin was that when I would boot to the Downloader screen (The blue screen where you have to press up on the volume button to continue or down to cancel) the phone would never restart on that screen. I figured if it was a battery issue then it would restart regardless of what screen I was on.
But, I noticed something after all of this. The LED stays light up blue when the phone is powered off. The LED lights work correctly when the phone is on (Red when charging, changing from blue to green in a wave like pattern when turning on).
That kind of made me rethink the problem, and go back to it being a battery?
So, this is where I stand now. The phone would boot up, but randomly restart. I thought the OS may of been corrupted or something went wrong during the replacement of the screen so i tried resetting it, etc. Now, it the phone is just stuck in a endless loop. I noticed the LED lights up blue while the phone is turned off, so it has led me back to thinking it's a battery issue.
Lastly,
I don't believe I messed anything up when removing the battery. I was very gentle. I was watching a YouTube video that pointed out that thier technician poked the battery in the video, and they kept it there so we could learn from their mistake. Their battery leaked out a little and showed some residue on the black part of the piece it is mounted in. I never seen in residue or anything like that when I did mine.
I also unplugged the battery first before unplugged any of the other ribbons connected to the motherboard.
I am new to repair screens and I wanted to try on some of my old phones to get practice. Although this issue is frustrating, it is giving me a loads of knowledge on issues. It would be greatly appreciated if anyone could help me out with this. I'm not sure where else to go from here. I do have a battery ordered, but probably will not get here til sometime next week.
Thank you everyone for taking the time to read this long post!
Try replacing the battery. Make sure all grounding pathways and connectors are properly connected. Sometimes they may use unconventional pathways like the frame or a screw.
Impacts that can break the screen can cause high enough G loading to internally damage chipsets, fracture solder bonds (including hidden BGA ones) and damage internal mobo traces.
The display and mobo when out of circuit are suspectable to ESD damage. Full ESD protocols and procedures should be followed. Even though many techs don't do this doesn't mean they don't damage hardware. It may take weeks or even years to manifest itself. Handle the mobo, display and sim card like a stick of ram.
In 11 years I've only seen one tech install a sim card properly; ESD mat and wrist strap.

Even though many techs don't do this doesn't mean they don't damage hardware. It may take weeks or even years to manifest itself. Handle the mobo, display and sim card like a stick of ram.
In 11 years I've only seen one tech install a sim card properly; ESD mat and wrist strap.

Hi!
Thank you for the detailed reply. Very insightful.
I've been at work for the last few hours. I left the phone powered off while I was gone. I got back and the phone is powered off, but the LED light is still blue. The only way to get that to go off is by unplugging the battery ribbon from the motherboard.
The phone was on at least 70% of battery before I left. I get back and it started charging at 20%. Mind you, it's been off while I was gone.
Do you think the safest route would be to unplug the ribbon until the new battery arrives?

If you think the battery has failed don't charge it.
Any swelling is a failure.
A sudden drop in capacity or erratic charging are also signs of a failure. I just went through this with my 10+'s battery
It's possible the battery was physically damage when the screen got broke, they're are really flimsy.
Best to rule out the battery.
It won't do your sanity much good until you do.
Examine the charge port PCB closely for any damage or solder cracks.
Examine the mobo as well. A stereo magnifying visor helps.
Hopefully the new battery will get it
Hello, I have the same exact problem. Verizon phone. Replaced screen from another phone. The phone boots normally, reaching the lock screen/home screen, but restarts after a few seconds. Performed a factory reset via the recovery menu, but now I'm stuck on the Verizon logo. Never-ending restarts. Never reaches the setup screen. The LED keeps on flashing blue-cyan at times despite forcing the phone off from maintenance boot mode (vol down + power). Tried factory resetting from there as well to no avail. Swapped back the old screen, but the boot loop persists. The battery is new (manufactured in 2020), had no random shut-off whatsoever prior to the swap, and had great SOT.
The worse part is the phone is undetectable via USB, the phone rarely fast charges. I suspect a burnt diode/capacitor on the mainboard itself because prior to the screen swap, I tried a daughterboard swap first. Both daughterboards work just fine and can handle both fast charging and data transfers on the donor phone. Both didn't work on the Verizon one. Can't even try flashing the firmware via Odin because of this.
Have you ever gotten to find a solution to this?

The part number on the daughter board must match the replacement. There maybe two US versions... if so they are incompatible.

I do have the SM-G925V (Verizon, 64GB) and SM-G925F (Global, 32GB). Originally, Verizon had a broken screen, a USB issue, and randomly restarts. SM-G925F did have a Knox-tripped mainboard and a faulty daughterboard, but only the 3.5mm jack didn't work.
Swapping only the daughterboards, I was able to use the Global just fine even after flashing the original firmware. The Verizon one despite having an older battery did suffer fewer random restarts and I started using it primarily as a hotspot device. The global one uses a newer battery I ordered online.
Prior to Verizon's factory reset via recovery menu, It had all the original components except the newer battery and the screen from global. I tried a reset because the random restart became even more persistent even while doing nothing. Now, Verizon is stuck, boot loop. I tried swapping even all the original components (older battery, broken screen) just to see if the phone will proceed to the setup screen. It didn't.
Were you able to fix the boot loop issue on your Verizon?

I know about because I ran into that problem on my N10+ N975U. Apparently there are 2 C port pcb variants. In my case the original pcb was still good so they just put it back in.
So much for preventive maintenance...

Sorry, I thought you originally posted the problem. I just noticed it was @TrumpXLV. Nevertheless, thanks for providing some insight. I did try to swap back all the original components on both of the variants, Global and Verizon. Did a factory reset via recovery menu on both, but only the Global one reset just fine and the Verizon one didn't.
I was curious if @TrumpXLV did find a solution. This is the only post I found that described the same issue, the same model. Might have to shelve this phone for now. Was planning to repurpose this phone in some way originally. I'm daily driving S10+ atm.
Hey all,
While I was watching a video 2 days ago, the screen started to glitch and the phone shut itself down. I tried to restart it by holding [power]+[vol up]+[vol down]. I got stuck in the boot screen, then it shut down completely. I tried charging it but it didn't work. I left it for several hours and tried again, this time it started to charge the battery. I immediately tried to boot it. It booted normally but froze at the home screen, and went black again. Now, I get no response when I plug it to my computer, I can't get into download mode, and it doesn't the charge battery.
Any help would be appeciated.
See if you can get into recovery, clear system cache.
I doubt this will fix it so immediately afterwards try booting up in safe mode.
Copy any critical data, enable debugging, prepare to do a reflash.
If you installed any recent apps, try uninstalling them especially launchers or power management. They may be the cause of the boot loop. Check apps listed as system Administrator in security for anything that shouldn't be there, and disable all.
Try a hard reboot (simulates pulling the battery).
If no joy, factory reset.
If this doesn't work try reflashing to the same firmware version.
If that doesn't work you're likely looking at a mobo failure.
Happy hunting...
Please read and observe forum rules.
Do not create duplicate threads... good luck.

Most probably a motherboard issue. I experienced something similar with a brand new Note 4 back in the day. It was repaired by the seller (motherboard replacement).

The BGA chipsets aren't tolerant of board flexing or direct impact; solder joints can fracture.
The chipsets themselves can suffer internal damage from high G impacts.
Internal PCB traces can also be broken by excess board flexing, they are many times fine pitched.
A good case keeps drops survivable by limiting the G loading on the phone.
However I wouldn't write it off just yet... gentle pressure on the mobo chipsets etc with a pencil eraser or such with the device on, may reveal a solder fracture or trace break.
Also inspect ribbon connectors for damage and full contact. Ensure all ground pathways are intact sometimes these can be hard to spot or use a screw (a short length wrong screw won't work).
