Completely unresponsive touchscreen - Verizon LG G4

Hello all,
I will preface this by saying that this issue is likely a result of water damage. However, my experience has been a bit odd. So someone bumped my chair, spilled water partially on my phone. I immediately removed the case and battery and let the phone sit for a good half hour before examining it. Looked completely dry so I inserted the battery and booted up. Went perfectly fine until the home screen appeared, at which point the screen did not register any touches and I could not interact with the phone. Removed the battery again and reexamined the phone: upon shaking it I found that some water shook free and was immediately worried. Let it dry for another half hour or so, rebooted it, and it worked perfectly for about half an hour, listened to music and such.
While texting, I noticed that there was some worrisome screen flickering going on so I removed the battery again and let it dry for another hour or two. Now I've reattempted to reboot it, but the screen absolutely refuses to respond to touch input. The phone appears to work perfectly fine and there is no damage to the screen I can see, nor does the flickering appear anymore. But touch input is fully unresponsive.
My current plan is to by a replacement digitizer, screen, and frame combo and replace that but I wanted to check in with the forum first to see if anyone has any ideas as to what the problem is and how I might go about verifying that the digitizer is indeed broken.

I've personally not known digitizers to go bad from a little water. Usually it's an internal area where the water is getting too. If you're no longer under warranty I'd take the phone apart from the back by taking out the screws and examining it that way. It may be too late for it if it's caused flickering in the screen. It could have weakened it. Am I saying don't buy a digitizer? No that's up to you. Unfortunately since you used it within a few hours of it getting wet I'm not sure. The best thing to do is to at least let it have a chance to dry overnight since the water gets in places that not much air gets to it takes longer to dry. Some have had luck putting the phone in a baggy of dry rice to extract the moisture. I've never had much luck with that method. I've always taken the phone apart as much as I can and then putting rubbing alcohol on the board to seep in where the water may have gotten and then letting it air dry. Make sure not to get it on the screen though. And with any advice like this I take no responsibility if the phone messes up, becomes unusable or turns into a Ferrari

Thanks a ton for the reply. I have essentially come to the same conclusion. It is quite an absurd issue that EVERYTHING appears to function, but the screen is no longer responsive to touch input. I'm going to try and replace the display body (only $50, can return it within 30 days if no luck). My Verizon contract ends in mid July so I just need a phone that can limp to that point or whenever the next Nexus is released.

Well, I managed to replace the screen/digitizer/body (essentially did a transplant of everything) and now my phone is back in reasonable working order. Had some odd issues with screen flickering again so that is worrisome, but the touch screen now works fine. Only issue is that the screen is absolute trash and is washed out, with major light leakage around the bezels (may have gotten some ****ty knockoff from China ).

Is the touch screen really that fragile or am I missing something?

I have had my VZW TP2 for a while now, and while I try to keep it scratch free it has had a bumpo and bruise before.
Yesterday is fell while I was stepping out of my car. I picked it up, brushed it off, and got angry when I saw a small knick, maybe 2mm long, in the screen. Angrily I turned the screen off and put it back in my pocket.
About an hour later I went to use the phone, and to my suprise, no touchscreen! LCD is fine, no distortion or damage what-so-ever.
Is it possible for such a small knick to completely trash the touchscreen?
I have tried multiple resets and cannot get it to recognize anything.
Short of replacing the screen and/or digitizer, anything I can do?

Not sure if I would calling dropping the phone a few feet from up in the air onto what I can only assume was concrete and not pillows a small "kick"
It sounds like your digitizer is pooched. If your phones under warranty just sent it away to get fixed. It shouldnt shake loose like that I dont think. I know things happen and theres nothing you can do about it when it does. With my touch pro I had a silicone case for it I dropped it so much.. And by dropped it I mean like it would fly 5 feet or more and then the back plate would shoot off and the battery would fly out... not good to do once let alone multiple times! I was sick of my silicone case (which I got after dropping the phone probably a good 10 or more times) so I took it off, a week later I was out on my back patio and had my phone in my shirt pocket. I was on my knees and bent over to pick up something and it slid out. Fell maybe a foot and I picked it up and there was a crack across the screen.. Son of a B$%^&H!
Just happened to land on the corner perfect I guess... Regardless point of that story is I wouldnt call the phone fragile by any means. These things are beasts! But as we know... stuff happens.
Hope it works out for you.

[Q] screen stopped responding - bad digitizer?

For the last day or so the touchscreen on my Tilt 2 will not respond. I thought Sense was hanging due to text messages so I deleted all of them this morning. That didn't help and neither did multiple reboots so I finally did a hard reset. Now I am really hosed since I can't get through the initial setup. Sounds like the digitizer may have bit it?
I am not at home to flash an official ROM right now but I will try that tomorrow. Other than that does anyone have any other ideas? I am paying for the warranty and insurance so I think I can get it swapped if I have to. Are they still sending out Rhodiums or do they have another device to send in its place now?
Okay, I just flashed the latest official ROM downloaded from HTC. Screen still isn't working. :-( Guess it's time to contact Asurion.
my tilt2 is also doing this, it stopped working about a week or two ago, then started working a few hours later. lately it will work sporadically and most the time not how it is supposed to. i have simplicity. i also have the insurance and i think mine is still under warranty, will i need to put the original sense back on it b4 i send it back in? also, on another note, sometimes when i plug it in to charge it the orange light doesn't come on indicating it is charging, i have to hold the power button for a few seconds. it started around the same time, are these issues related.
Possible fix
Ok, so I have learned that these screens are pretty sensitive, especially if you put them in your pocket. You can sometimes revive this by sliding your fingernail into the seam along the outer edges of the screen and running it along the seam as if you were trying to peel the front (digitizer) off of the LCD. It somehow releases the stuck screen or something. Mine has been doing this off and on for a while and I've been able to revive it several times with this method, though it's getting too frequent now and I'm thinking of trying to replace the digitizer all together. I'm afraid to make that leap though.

The reason this "fixes" it is there some dust or dirt between the screen & panel. If enough gets in there, the digitizer gets confused and ignores any presses.
If you completely disassemble the screen and thoroughly clean it, I bet it'll be fine - no need to replace anything. However, this is a very tedious and delicate process, so be extremely careful.

I think I literally sweat my phone to death...

Long story short, I was working on my GF's grandmas car, and she calls so I was talking to her. I sweat a lot, and the phone screen usually gets covered in sweat. I guess some of it got INTO the phone, and broke my god damn screen. At night, the screen was flickering brightness. I rebooted the phone and it went away, so I figured nothing of it. This morning, I woke up and the screen was flickering bad and then it went black and now it randomly draws purple. the phone works as I can hear it open and run apps. The screen is just black. zero physical damage, water marks on the phone are white. I can see where it was wet on the bottom of the phone inside. Tried taking out the mobo and looking, no signs of corrosion.
help... I don't want to throw a ~$150 LCD screen at it.

Mineral water "bath" - will my phone evenutally die?

Yesterday my phone got spilled with sparking mineral water. I found it in sort of boot loop, realised what happened, pulled the battery, tried to dry it a bit, tried turning it on (not a good idea, I know now), then turned it off again and left it to dry with a fan. My phone sort of turned on then, only the screen was still a bit weird, shortly flashing from time to time from brown color to home screen. Anyway, today it seems to be OK. BUT I read now that any water that is not distiled water can cause corosion because of mineral content. Obvisouly my water had lots of mineral contents. So my phone is now just hanging by the thread before it dies? I am not about to go get it all wet now to wash it down with distiled water, alchol or one of those repair kits they are offering. I might just make things worse. Does this mean I better start shopping for Note 3?
Water just heavily increased the probability for your phone early retiring.
If say for healthy phone the time before 50% fault chance is 5 years of everyday service, you shortened it maybe as twice.
Yet it may be fully conditioned for next 10 years. Or be killed tomorrow from other reasons...
I'd start to collect money for the next device. But would never rush to buy it before the days of the current one are over. it's not a too long wait those days, you have plenty of sellers.
I always have near my old Motorola Atrix with a parallel SIM card. Helps me when I overplay to much with ROMs and kernels.
Well that sounds pretty encouraging in a way. Thanks!
I have a N1 which was in the washing machine for at least 20 Minutes back in 2009. The bluetooth chip was fried but everything else is still working.
If you wanne be sure that the problem is note getting bigger you have to make sure the phone is completely dry before using it. I'd turn it off, remove the backcover, put it in a rice bowl and let it sit in a warm and dry enviroment for a few days. Mineral water is one of the better things you can wash you're phone with .

[Help] Display not responding

Alright guys, I need help. I purchased my device right at the launch day. After a month, I accidentally dropped it badly, and even after it had tempered glass at the time (didn't have bumper) the screen got cracked along with tampered glass. Device was new at the time and I didn't want to spend another 100 bucks for display. And it wasn't that much badly damaged either, so I could live with it.
Fast forwarding to this date, after 2-3 months, the device was lying on the bed. A minute before it was working completely fine, but now it's display is dead! It was just lying there and there was no damage done whatsoever.
LEDs, charging, everything works just as fine, but the display shows some random greenish strips at random places when I press power key to turn it on.
Now, earlier accident was not covered under warranty, but this is definitely not my fault. If I take it to care center, how can I convince them that the screen did not die because of accident and that the accident was 2 months before.
Kind regards
try to heat down and the bottom of the screen. sometimes helps for amoled display if there isn't any visual damage to actual screen under glass.

Like I said, there are 2-3 cracks on screen as well when it was dropped earlier.
