Finally fixed my screen. Never touching paranoid android again.
[G2 General] butler360:
Same could happen on another ROM... :cyclops:
[G2 General] Khant:
i can guarantee you that it is a software problem. been a PA user for years. I am not hating on the ROM, just the weird kernel commits that some developers merge in. I'm not saying there aren't other ways to damage your screen, but software is probably the most common with us flashers. the PA by houstonn seems to be fine though, since he decided to go back to older kernel and disabled gpu and display enhancements.

You can get a new screen for 45$ these days though, so i'm not going to stop trying out new roms if i get the chance.
[G2 General] Formhault:
Same for all those people who got defective touchscreens. Or flickering screens. All while being on stock, with LG G2 units from the late 2013 lots. Yeah... it sure looks like a software problem... :rolleyes:

With all these variables in place, nobody can guarantee it is a hardware or a software problem. For all we know, it could be both in some cases.
[G2 General] drivenby:
From what ive seen it does seem more common in people that frequent aosp roms .

It has happened in LG stock roms but compared to the number of people getting it on carbon or paranoid, the number seems lower.

This is just according to that old poll.

It could also be just a bias because of the population sample from the poll (xda members are more likely to flash roms than the general population )

Personally I don't dare to try any aosp roms in this device lol, i've been keeping it stock .

Sorry a little OT, but if you buy a used G2 will Verizon still honor warranty? Is there a way we can check how much time is left on the warranty? Thanks.
[G2 General] wulsic:
The best thing you can do is ask Verizon about that warranty cause I read that some people buy Secondhand stuff like a tv, turn it into warranty and then the original owner gets the money refunded. So I would ask it first and also ask about the months. I believe that you can check your warranty if you placed your imei in some LG link:confused:

Similar phone, different warranty...
[G2 General] freinet:
Hey guys,

I hope you called me in the club welcome!:(

I flashed unofficial cm, setup phone and play with settings and phone for some hours.

It was not hot and I noticed nothing special.

In late evening I turn off phone and put it in original charger, waiting for loading symbol.

All was fine till now.

In the morning I turn on the phone ... and voila...BLACK LINES ON THE RIGHT SIDE!

Shhhhiiii***

Now I am going back to stock and try warranty.

Is there anybody from Germany who have black lines and managed it with warranty?

freinet
[G2 General] drivenby:
Here's a static out of my behind but I think 90% of all blacklines are on AOSP roms or people that previously flashed aosp roms....

So if you are reading this DON'T flash any aosp roms.

Disclaimer : I'm aware of reports of people that got the lines on pure stock, it could be because of the site we are on (enthusiast modders) but I think those are in the extreme minority of cases.

I don't remember if anyone reported that the screen had any kind of problem besides the black lines (I noticed they appear to be white when twrp is loading, and afterwards too I think).

So this Rom was installed and up and running ? Or did this happen whilst flashing, can we confirm roms that does not have this issue please. I'm a d802 with a LG screen and was running ACIP with out any issue's well that goes with any roms that I Have flashed. Is there any facts that we can put in place, example does this happen to every veriant. Or is there a particular screen JDI or Lgd, this happen too. Has PA responded to this issue? Have So many question anyway let's try and get to the bottom of this.
[G2 General] mandroid717:
i have only installed 2 custom roms and that was a few weeks back. i mainly stick to stock modified roms. i got the lines after my cpu/gpu overheated and the screen froze then turned a nice shade of grey. after rebooting i got this.
[G2 General] NicoC72:
I would like to know which ROM's are safe as well. I'm on CM11 M6 and haven't encountered this problem. It seems Mahdi ROM is also safe. Haven't seen anyone report issues with the Cloudy ROM's, so I'm guessing those are fine as well.

I've got a D801 with the JDI panel if that helps.
[G2 General] thejoshiewawalee:
Had this issue a few weeks ago. I thought it was a hardware problem, went back to stock and sent it to lg to replace the screen. New screen for free because of warranty yay. But I hope this issue would be solved soon.

[G2 General] Tubamannen:
Is it safe to just flash back stock with lg recovery tool before sending the phone in for warranty screen replacement? or I need to make something else (like resetting the flash counter on Samsung phones)?

[G2 General] fordmanck:
I'm pretty sure that's all you need to do.
[G2 General] thejoshiewawalee:
That's all you gotta do. The root checker will only be shown in the download mode, and it is reversible by simply flashing stock. For me I told the guy the pixels are dead and when he saw, he replaced the screen on the spot and returned it to me. Had to wait maybe 15-20 minutes. Don't know about your country cause I'm from Singapore

Ok... I'm still on weekly slimkat (which is cm-based 4.2.2) but I like to be prepared just in case... test builds are 4.4.2 and It's just a matter of time before official weeklies are too. I'm Swedish btw... I don't expect that fast replacement, but I'm lucky if it is replaced by warranty :)

[G2 General] bps119:
I believe he has a theory of what causes the issue.
[G2 General] FingerMove:
As far as I read Omni also has no complaints and that's what I'm running now. I'm actually extremely lucky, because I wanted to try something new and flashed PA Beta 5 on my d802. Few days later I flashed PA Beta 7, which is said to most likely cause all these problems with the screen. Luckily, I didn't get those black lines until now. When I read about it I almost got a heart attack, because not only did I download PA Beta 7 OTA, I also downloaded the gapps OTA :eek:

I instantly flashed Omni after reading that and I haven't got any of those issues stated here. But maybe I've dicovered something different: I watched some videos yesterday in software mode (YUV) using MX Player and noticed white lines across the screen when there was a scene change. This would support the theory that it could be the GPU instead of a faulty display, I suppose. But I am not a developer, so I don't know what these commits are supposed to mean that I read some pages back.

Maybe someone can reproduce this, at least that's the only hint until now on how to fix it whitout sending it in for repair.
[G2 General] :
maybe its gramm
[G2 General] gypsy214:
I have a suggestion. I might be wrong I don't know much about hardware but I see it impossible for a custom rom to break your screen permanently.

When I cracked my screen I replaced it myself. If you know the screen have two connectors to the motherboard. One is on top above the battery and the other one is below just above the microphone. Next to the connector below there is a small square with small adhesive covering a bunch of connectors. I realized I had to be very careful with that and that adhesive is very delicate and can moved with ease. First I was not paying that much attention to it because I wanted to get my phone up and running. So I notices those lines on the screen. It was horrible and I thought I have bought a bad LCD. When I opened the phone again I noticed that square the comes with the lcd with several connectors looking like. It was up from the adhesive I put a peace of electrical tape to cover it and get it back to the motherboard. When I power on the phone the screen was 100% good.

So I see that it only happened to a few of people. It might be a coincidence that their phone gotten hot enough to melt that adhesive from that square to the motherboard. I will take some pictures of what I'm talking about to explain it better. Like I said It might not be it I dont know much about hardware but would like to know from somebody that have this issues to take a look at it.

[G2 General] wulsic:
If you had used it then yes the device is unrooted but the root temper flag maybe not. Boot into download mode and see if it still says rooted. To reset it you had to use normal flash or cse flash I am not sure anymore I think the second one, google to be sure.
[G2 General] El_Assassino:
Is a screen replacement the only way to solve it?
[G2 General] Formhault:
Looks like it, yeah.
[G2 General] breakfastdude:
I got the "halo" issue which I described a few pages behind. Was scared to know that it could probably be a precursor to the black lines-damage on the screen. Plus, I had the touchscreen deadzone issue, too. Finally decided to take it in for repairs under warranty. I'm glad I did; they replaced the whole screen assembly and everything works fine now.
[G2 General] Formhault:
Did they replace the glass, too? Or just the screen assembly (digitizer and LCD - the glass isn't glued to them in the G2)?
[G2 General] breakfastdude:
I think so, they did. For one, the color of the white plastic surrounding the glass doesn't quite match the whiteness of the back cover now, whereas it was a real good match before the repairs (I'm assuming the glass is not removable from the plastic sides with the chome trimmings; also I'm pretty sure the back cover was the same one I sent the unit with -- I have some specific scratches on it). Also, I sent mine in without any screen protector and the protector strips around the sides; it came back with all those, just like when I got the phone brand new.

Keep in mind though that I'm in Japan, and my unit is the Japanese variant, and LG Japan was the one who fixed it.
[G2 General] Formhault:
Nice.

Yeah, maybe they do a better job in Japan, but it's LG anyway, so I gusss they should have the same standards.

Speaking of case color... The screen side of the case (so from the chromed trim towards the display, you know) is a blueish white, so not exactly white. In contrast, the back side is yellow. I think Samsung did a better job at painting the Galaxy S4 in white than LG did with the G2. Anyway, I use a case so I don't really care much, but still...
[G2 General] Strif3:
Heloo i have some questions regarding this problem that i recently discovered.

1) How is this posible to do a permanent damage through software?

2) I can get screnn damage from any rom,would you advise me to stay on stock coz curently i have Pardus rom.

3) How can i see wich display i have from ? JDi or the other?

Thank you
[G2 General] wulsic:
Hi Strif,

These are my answers on your questions with the things I know so far,

1) It is possible if like some things are experimental or not meant for this device, that's why for things like graphic cards and other stuff there are Testing Drivers or experimental. We do not know or this issue is caused by heat/software etc but I think it's software because by the people somethings get inverted colors.

2)My advice is to stay on stock if you want else just flash other roms but do you have warranty? just to be sure.

3)http://xdaforums.com/showthread.php?t=2770769 Download the app and install it. It will show which screen you have after answering some questions I believe. I don't know or its accurate since I don't have this phone, Second thing you could do is download terminal emulator and execute these commands

su
cat /proc/cmdline

Also, G2 roms are getting auto display detection, I don't know whether or it's on all roms but on some roms it is already, also use TWRP from DR87 to prevent the lines issue. It's not sure or it prevents the lines but we think it will since we still don't know the cause. I hope I could helped you a bit.
[G2 General] Strif3:
Downloaded the app that checks what display tipe i have and it says that i have lgd/lgit,done it 3 times already what does that mean? my dispaly is not a jdi?
[G2 General] Formhault:
LGD/LGIT =/= JDI.

So, it is LGD, not JDI.

so does that mean that im safe? can i flash lets say cyanogen mood? coz im geting bored of stok after 1 year
[G2 General] Formhault:
Did you even read the freaking OP?

No display is safe. LGD or JDI. We're not even sure what is the culprit.

Flash LiquidSmooth or AICP or Mahdi. Not CM. You should be safe with those.
[G2 General] siggey:
You are free to do what you want to do, you know the danger. If it is really heat problem, put the phone in the fridge and flash.... Or use a recovery with termal control...

I just provided you a short summary of what we think the problem may be. For the 100th or so time in this thread.

[G2 General] jal3223:
I thought CM was considered "safe". I know that none are safe, but I didn't think many people were plagued while running it. Did things change recently?
[G2 General] Formhault:
CM is generally safe, but some builds aren't (weren't). I'd stay away from CM, if I were you. I mean not only there's a chance something will go wrong, but there are many more other way superior ROMs, like AICP and LiquidSmooth...
[G2 General] doctoralex:
Sorry for the old reply but I think that the majority that people are here have flash (or they have the indention) a custom rom. So the question isn't if is happening less in stock roms but in which customs is likely to be happen. From what I reading these are the the AOSP based. But a survey will give more accurate information.

PS. It remind me that old good no call bug in Optimus 2X. :D
[G2 General] drivenby:
Yeah I meant custom roms based on stock, like cloudy g2 and g3

There was a poll a few months ago and most people with the defect were using aosp based roms.

I don't know the sample of stock based vs aosp but generally I think more people use stock based roms than aosp.

hello,

i have one lg g2 from japan (L-01F but i broke the screen and now i want to change it, if i buy screen from lg g2 d802 it will work ? or i need to buy an L-01F model screen ? thank you for answer.﻿
[G2 General] Formhault:
I'm not sure. They should use the same connector and display controller. Buy a part (they're rather cheap on eBay) and see for yourself. Maybe you can return it if it's not working out for you...

I doubt you can find any info related to that with a simple Google search. I mean heck, there aren't even many (good) LG G2 teardown videos out there :(
[G2 General] Snepsts:
Hello friends,

I do not own the G2 myself, but my brother does and he made me flash Omni, Cyanogen, and then finally Carbon which didn't go so well. I have him back on Cyanogen for the moment as it seems to be under control. We got 11-13 black lines after the Carbon boot. I did a lot of reading and assumed the thermal control would take care of the Carbon black line problem. I am currently using the dead pixel remover (Which to my surprise has removed all but 6 lines so far.) But after a night and day's worth of this apps run, we seem to be on 6 that do not wish to leave. I am looking into screen replacements incase the warrenty isn't on our side. Is this what I would want or...? This is very upsetting as the build quality on the G2 and my G Pro are both outstanding. Minus this problem. Unfortunately we suffer when LG refuses to release their full source code. :( At least the problem would be reduced to only hardware and not also software triggers. I'll also see about sending it in for repairs. We did not explicitly buy warrenty but we did buy the phone through AT&T's next plan. Is that also going to be an issue? Does anybody know if asking AT&T for a replacement is ideal or do we go to LG? Thank you in advance, and sorry for my wall of text. I am concerned but reading has not revealed these answers to me.

Also, anybody who fixed all or some of their lines, how long did you run your dead pixel remover app for to remove the lines you removed?
[G2 General] HueyT:
AT&T will replace under warranty within 1 year if you kdz or tot back to stock to remove root and hacks.

Pixel remover apps for this type of damage work best at max brightness, constant screen on, and on charger to heat up panel X 1 hour. If it's still there then ur stuck with it.

Changing screen ur self is not easy and may cause worst damage than a few thin black lines

[G2 General] Compass Linux:
Tricky question.

As an example, there is a South Korean G2 (can't remember the model number right now) that has a smaller battery but includes a SD Card slot. This might rearrange the phone internally, so much so that the screen connector is placed differently than a D802, for example.

If you find the screen on ebay for example, and the description doesn't state L-01F compatibility, ask the seller before buying.

Compass.
[G2 General] Formhault:
Well that's the model right there : L-01F. I remember seeing so many batteries for that G2 variant on eBay... 2610 mAh or something... What a joke.

It's funny. Most sellers advertised it as being D802 compatible in the title, but it was clearly for another model (as the description of the item said).
[G2 General] Chaosz-X:
Is there anything known about which models do and don't have this issue? Is it specific to a few countries? Here in the Netherlands, I haven't heard anyone with these issues yet for example. Or is there any approximate manifacturing date after which it should be fine to use custom ROMs?
[G2 General] Formhault:
Don't even bother to read the thread. It's pointless.
[G2 General] Chaosz-X:
I read at least 80 pages of the thread, but I haven't been able to find answers to the questions I had ;)
[G2 General] siggey:
The thread had no answers. Sometimes a screen brokes. Like every other electronic devices.

_____________________________Write less read more and be smart
[G2 General] Formhault:
Figured this manner is actually bigger than what a simple search could answer. I apologize...

We don't know (for sure) which models are affected. US users (D800, D801 and such) were affected. International (D802) users were affected. Even a developer (Cloudyfa) was affected (and his G2 was the Korean variant). Basically, every G2 out there could be affected.

Well, Cloudyfa's phone didn't really exhibit display issues (bands & such), but rather digitizer issues. I guess this still falls into the display issues category :silly: . His touchscreen driver went funky.

Manufacturing dates... Yes. It looks like G2 units that were produced prior to December 2013 / January 2014 are much more prone. But regardless, being covered by warranty for an extended period of time is mandatory, if you ask me. I mean... you can never know.
[G2 General] freinet:
Anybody have the screen damage twice? I mean after replacing the display, screen damage again(black lines).

[G2 General] Chaosz-X:
That's a good question! If it does not happen to these people again, it is pretty safe to assume that the manufacturing process has been changed to minimize the chances of this happening.

Black lines on replaced screen

I am in the same boat. I have a LS980 on sprint. I received my new display assembly last week to fix this problem. To test the new assembly, I attached only the display connection and booted up the phone. The new screen had the black lines!. I am currently on ZVD.

For me black lines appeared after flashing "pa_ls980-4.4-20140629.zip", "pa_gapps-modular-mini-4.4.3-20140629-signed.zip", and "ls980_PA_G2_kernel-kk_JDI-panel_4.4_RC2_0620.zip" in TWRP and then rebooting. I have had black lines on the right side ever since. There are at least 50 lines now.

Sorry I am no help. But yes I am in the same boat.
