Hello.
I was working outside for more than 8h and at that time phone was lying in the sports bag covered with some clothes. When I turned it on the battery temp. widget showed 5 degrees Celsius (in fact it was cold).
The first problem was the screen - it showed some artifacts, random RGB pixellation when waking up and while writing SMS screen just froze and only touchscreen worked, had to turn the screen off and back on to get it work.
After warming the phone to 20 degrees the screen started to work properly with no problems but 1 hour ago something started to piss me off. Touchscreen started to self-detects touch points even when I don't touch the screen. It appeared for the first when I slightly pressed "delete character" button (I use better keyboard 8). That maked touch screen to work horribly and pressing random keys near delete, 3 or 5 times per sec for a second or two...
I've already tried factory reset and even reflashing the ROM (stock nordic 2.3.4) but the problem is still occuring.
Any advice? ...
Common problem with no apparent fix.
A way you can make it better is to install Swype, which is how I've got around the same problem on my phone.
I get it in the morning after sleeping in my 24 degrees room everynight...
Normally have to bring it out of my room for 5 minutes or so and allow it to function again.. If not a restart normally works..
Phone works fine if im using it while the aircon is on though, presumably because the phone is generating heat to counteract the cold ._.
Yesterday I got pissed off, grabbed the phone and started to heat it with hair dryer and then polished it with a cloth and everything is right with the touchscreen (maybe there was some dried sweat on the screen I know some guys who had this problem and sweat was the one who caused it).
But random pixellation and screen freezes are back. I think the problem is with the screens' ribbon cable because sometimes when I slide my phone it freezes for a few secs. I remember I've slided the phone when it was very cold, maybe something wrong happened with the ribbon cable. I have to disassemble the phone and check it out.
Sounds like a trace amount of water damage perhaps from condensation while in your bag.
Fortunately NO!
The problem was with the flex cable connecting down part of the phone with the upper part. It's partially broken, probably it happened because of cold wires and my sliding.
This ribbon connects everything from the upper part (LCD, camera etc.) so it needs to be replaced. I'm gonna see if any of my towns' repair centers are able to fix it.
edit: Professional diagnosis:
Interrupted flex cable connecting upper part with the bottom part - two most left pins broken, screen shows constant "random RGB pixellation".
Bringed my XPLAY to the authorized SE repair center and waiting for the ppl there to fix my beauty...
ribbon that connects everything from the upper part to the lower part? do you mean the long and wide ribbon that is kinda folded when you open your phone? IS IT? jeez that's my problem, too. I haven't been using my phone for more than a week now.

Hi guys!
Unfortunately I dropped my LG G2 into water yesterday. That was my first time that I had my phone wet, so I panicked a bit and acted on instict, which probably wasn't the best option.
The phone was in its Slim Armor case and was submerged in the water for maybe a second or two. I removed the case, quickly attempted to turn off the phone (it reacted normally, both the switch and display, although signalled that jack was inserted, which wasn't true). After drying the phone with a paper towel and mouth-blowing some water out of USB, jack and speakers I tried to turn it on again (which, as I read later, wasn't the best idea). At first there was no reaction. After drying it a bit more I tried again and... surprise, the LG sign showed up as normal! However, my enthusiasm extinguished quickly as Firmware Update screen turned on. and looked exactly like this (with only a bit different code). I cannot post links, so please enter it by yourself if necessary.
chip.de/ii/2/2/0/7/8/7/3/1/LG_G2-Unroot-Foto2-5a02458aba271a92.jpg
I have never seen that screen before and my phone has never been rooted. What is more, it ceased to react - it did not dim for hours and didn't notice pressing buttons in different combinations.
I then put it in rice and silica gel (still lit and showing the Update Screen) for some hours and tried to turn it off again. Fortunately, this time the switch button worked.
After a brief search in the internet, I removed the back cover and wiped out residual drops of water that were underneath it (not really much water was there, single drops spread all around, did not even look like penetrating into deeper parts... even the water indicator on the right of the camera remained white).
Now the phone has been sitting in a tightly closed jar with rice and silica for at least 12 hours.
What should I do next? Should I try to switch it on again?
May the Update Screen be a sign of a damaged motherboard, or maybe some less dangerous short in the USB socket and switches (as I read, the Update is turned on by a combination of switch and volume buttons and plugging an USB)?
I'd be grateful for any help!
Greetings!
I recently got my note 3 wet (clean-ish lake water) and immediately got the battery out and the phone dissasembled and into a bag of rice.
after a few days I reassembled it and booted it up and I can hear the startup sounds, feel the vibrations from power up, reboot & charge and I also can hear all of my notifications including ringing calls.
The problem is I cannot get the screen to turn on*.
What happens is the back button and menu button led's light up at the bottom and the screen sometimes flickers. I have got the screen to turn on though really rarely (playing with it and removing/readding the battery, rebooting etc..) and when I DO get it to turn on all functions work perfectly as if the phone was never damaged.
My question is, what components can I take a closer look at that would cause this behaviour? I would say that the screen is kaput but when it turns on everything works....
I am asking here as my google fu has not dredged up anyone with this specific problem before.
I have cleaned what appears to be corrosion or water spots on the larger copper traces on the mainboard with 99% iso and dried then reassembled but no change in behaviour (it did turn on once after I did this and work).
I tried a new OEM battery, no change.
Any and all advice is appreciated and yes I will order a waterproof quality case if I can get it working again

You acted perfectly after getting the phone wet, so congratulations. But unfortunately, screen failures are fairly common in phone-wetting scenarios.
What you can do is try keeping the phone a couple of days more in silica gel bags/rice to see if there still is moisture in the screen assembly. If nothing changes, all you can do is replace the whole screen assembly.

Can the screen be submerged in isopropyl 99% to displace any water or will that damage it?

Alcohol should be harmless. Go for it, you have nothing to lose.
I think you should put your phone in sun light for 40 minute without battery. after that let you phone cool. then Try to boot.If not work then open that back part then try again for more 30 minutes. I think it will help you.
in my case it works on samsung galaxy s.
God bless you & your phone.
Weird problem but my phone has a screen that shows a distorted display or sometimes just speckles of random color. It seems the problem mainly occurs when the phone has a SIM in, gets hot, or maybe humid.
I ran stress tests on CPU and GPU for hours with no sim and it worked perfect. Then I put the sim in and later the display went crazy (this is not a touch screen issue). Then I took sim out and it went back to normal. I thought I fixed it by blowing out sim slot, but then the problem reoccurred. I had to take off back of phone (while it was on) and it was immediately rectified. It makes me think that something is getting pressed down too hard. I tried disconnecting the video cable and reconnecting it to see if that will fix it, but this particular phone has not been opened since the factory so it seems weird that it would suddenly get a loose cable.
Any ideas appreciated. I would like to fix it.

Had this issues after replacing my display!
Antenna cable is near the display eletronic parts in the lower part of the phone, near the usb connector, you've to put a tape on the eletronic, or you'll ever have this interferences when you use the antenna! (Antenna is the grey cable), display elettronic parts are a little square, betwen battery and USB connector, and have the grey antenna cable on them beacouse the antenna connector is near in this part of the phone! Sorry for my bad english, hope this help you!

I haven't replaced the screen on this phone, but when I took off the bottom piece the connector just fell of lower control board. I snapped it back in and we will see. Maybe it simply got loosened somehow by shaking etc... Hopefully that rectifies the issue. Thanks. I was going to swap the lower board (I already swapped upper one) but maybe I can avoid that now.

Can you post a photo taken by other phone (not a screenshot from your G2) showing your G2's current problem?

It was the lower connector like was said earlier in the post. I had already swapped the upper board with the other phone and the problem continued, when I went to mess with the lower board the connector was loose and upon tightening it down it started to work. I have had an instant of glitch two times in the long period since then, but it goes away immediately. It seems the connector need glued down or something who knows. I am happy though it is working well enough to last me until something comes along that makes me want a new phone.
Hi, my phone with just three weeks of use, my screen stops working suddenly after ending a call. At that moment I see that the screen does not turn on, I press the lock button and I hear the blocking sound, I proceed to remove the battery and turn the phone back on, but the same thing happens. I do not have a boot image (no LG logo, nothing, only backlight for about 2 seconds) when the backlight is turned on the screen, the bottom edge of the screen gets very hot (even faster and much hotter than the CPU) . The phone reacts, I receive calls, notifications, but I have no picture on the screen. Okay, I'm starting to think it's a hardware problem and I disarm the phone to check that the LCD connector is not badly connected, but everything was fine. I assemble the phone and turn it on again and I still have no picture. I leave the phone charging all night and I go to sleep, the next day the screen worked, but only a few minutes, until it became pixelated as in the attached image.
Now the phone does not give image (only backlight) and only sometimes gives me image, but pixelated. I have been investigating, and the only thing I could investigate is that it can be screen (flex ribbon damaged), overheated GPU or CPU, defective GPU. So I do not know what to do (a replacement is not possible). I need to know if the problem is the screen or the motherboard, in case it is the motherboard I can bake the motherboard in the oven to try to perform a reflow of the GPU, just as it happened with the LG G3 when it reheated and this was a solution.
What do you think is the problem? Sometimes when I have pixelated image and I turn off the main screen, the time shows perfectly on the secondary screen without pixelation
I'd first check the ribbon cable and any other cables or connections to make sure that's not an issue. If it is the GPU, please, please take it to a professional who can reflow it correctly. I can not stress this enough -- the risk you are taking by putting your cell phones motherboard into the oven is astronomical. You could essentially take a phone with a GPU issue and turn it into an everything issue. :\ I used to repair Xbox 360s and Playstation 3s for a living and I had a BGA rework station, you have no idea how many times people brought in baked motherboards from attempted home repairs. You can find these services cheap all over the internet. Just make sure you select one with plenty of positive reviews.
Edit: I also don't recommend a heatgun reflow unless you have something to mount the heat gun with so you can attempt to replicate a BGA rework station environment. If you are dead set on repairing this yourself (if it turns out to be GPU that is) -- then I highly recommend doing this instead of the oven. Watch lots of youtube videos first. PM me if you have any questions. I can't promise I'll get back quickly as I have stuff to deal with here hurricane wise.
So I am at the beach for the week and started getting the moisture detected nag at night. I cant find any way so far to over ride this. Yesterday I was able to charge the phone by plugging the charger in and turning the phone off. I wake up this morning and have gotten the error again. Now I am down to 10% and the phone keeps turning itself back on everytime I turn it off while charging. I have tried leaving it plugged in and plugging it in while off. I have turned dev options on and off along with changing it to MTP mode and using the PC. I have tried a normal charger and a dumb charger.
So someone at LG seems to think they know better than I do. How do I turn this feature off? I know there has got to be a way to make your phone stay off? What if the thing dies now, the hotel catches on fire, and we all burn alive because my phone is dead and cant cant call for help? (actually I dont know that the phone would help to much then kind of like the kids that tried to text 911 during the Va Tech school shooting instead of fighting back or running away) There should be an extremely high liability in not allowing someone to charge their phone.
No I have not taken the phone in the water. Besides it is supposed to be ip68. I was going to try and pick up the buy one get one V30 deal. At this point after the gps fiasco with my old G5 and now this I want no parts of another LG. I dont even want a smart phone but a dumb phone. In fact I want a retarded phone that all you have to do is hit 10 numbers to make a simple phone call.

Hello , yesterday i had my first "fake positive" moisture detection. In my case i used pendrive made of metal which was cold to touch. When i warmed it to room temperature it worked just fine. Maybe your cable connector is too cold?

Thanks. I have tried multiples. Yes it is probably a little more humid here but it shouldnt be enough to trigger the sensor. Afterall last summer I rolled with the thing in my pocket and was sweating all over it. Also, the night I got it I spent one of the nights in one of the courts in richmond looking for someone at a running pace and in ripstop 50/50 nylon without throwing the error. I am thinking my phone might be not quite right. I wish there was an override.
So I found out what it does when it dies finally. It charges to 5% then cuts back on and dies again. I am all about technology but only when it works.
-update.
Went out to swim and before I left I took the rubber case off and jammed the whole phone into one of the vents on the PTAC and cranked it up to 11. I got back and now at least it is showing it is charging and not cutting back on while doing so. Once I get it to 100% we will repeat the process. It is very moist here but I dont see having everyone with a LG or Samsung phone not being able to use them. Yes I am staying in a resort in a first world country not in a shack in off the coast of Lebanon or something.
Try this. exact same thing happened to me.
My LG G6 all of a sudden stopped charging, it said moisture detected and USB port, charging blocked. And then my phone died. I asked my phone provider what to do, they said to call LG. LG said it's because I haven't updated the phone, but my phone was dead. So if your phone has enough battery power to do an update, do it right away. What I did was took it to the store where I bought my phone, charged it wirelessly enough so I can do an update. And that's it , my phone worked fine after. Hope this works for you
You can try this
*#546368#*930# ----> SVC Menu ---> Moisture Detect Setting ---> Disable
Replace 930 with your G6 model number. Mine was 873 and I turned it off. I'll have to test it later to see if I still get the message. Alternatively, what other thing worked for me was switching around the usb type c end that goes in the phone to the smooth side facing up. The connected side always sets off the message
There appears to be a continuity sensor at the rear of the port. If you look to the left and right of the wafer connector in the back of the jack, you'll see two little contacts. My guess is that these create a circuit when damp or covered with any type of slightly conductive dust to trigger a cutoff on the charge port. I had this issue starting at 2am last night (hadn't been outside since 7pm that evening, phone in pocket) throughout today. I tried just cleaning out the port with a microfiber cloth, that didn't seem to do it. So ultimately I ended up shutting the phone off, getting a cotton swab damp with 90% isopropyl alcohol, swabbing the connector until the entire thing was damp, and blowing it out with air duster. Then I used a flat toothpick to clean off any remaining debris and dust inside the ports. No error since, been about 30 minutes. May not solve for you, but this isn't necessarily just water related, definitely seems to be triggered by dust and debris covering the contacts at the rear of the jack.
Edit at 2230 EST: Going on 6 hours now with no further issues.

How did you get it inside, I'm thinking I did a poor job cleaning the port but a needle barely fits.
Here's my post:
"The message appeared randomly while charging one night. It was nowhere near water for several months and I work in an office.
What I've tried:
- Drying with a hairdryer (not even a temporary fix)
- Force stopping LG system and LG server processes. I even disabled them with package disabler!
- Disabled the moisture sensor in secret menu. Warning still shows up! Even if I try to turn of the phone and charge it.
- Cleaned the USB C socket with a hairpin and cloth
- Cleaned under running water, swapped with alcohol and dried again (getting desperate)
It does however charge if I plug unplug it in like 5 times. Really annoying!
It does this regardless of charging cable, I tried with 5 cables at home and work.
I read somewhere that the pins were causing a short, but the pins are inside the cable right?
What else can I try?"

Funny, I just tried this and still get the error. You'd think disabling it would remove the damn notification/it from working....
After all the **** I did, I found my problem and solution.
It was because of my charging cable that had bent pins, yet oddly enough the moisture detected error persisted with other cables.
Thru away that cable, then reset the phone cache and soft reboot (volume down + power)
Hope this helps.
Used trimmed down tooth pick and nail vanish remover - gently cleaned and my wife hair dryer on low ...and Voila" back in business ! Thanks for basic idea !
