Thanks man i thought that buying a new lcd panel would fix it but apparently not, i also have a sprint version as well and this problem appeared right after i flashed the beta paranoid 4.6, then flashed back to stock right after that but it didn't seem to fix it. What do you think is the problem.
[G2 General] Chaosz-X:
To figure this out, we need some clear statistics. One thing is for sure, a spreadsheet with just which ROM one was using, when the device was bought (what use does it serve to know if it was in 2013 or 2014, data has to be specific!), and also entries from people without any issues are required to know what is going on. The data that has been collected is of no use at all to figure out the cause or to learn which devices are affected. I will build a new form with questions that allow us to get more specific details to say something useful about the cause of it. I'll upload it around monday/tuesday, first I have some finals to take care of :)

[G2 General] fundoozzz:
We do not know what percentage of users are actually affected. Will it not make sense if we make a survey for all G2 users and not only for the one who got black lines..

Something like..

1. Did you got black lines? If no then what all ROM's you have tried till now (with option of different ROM's)
[G2 General] nemolivier:
Me. Two different ROM. Two different history (one after a call and freeze, one in recovery (that was before recovery with temperature control)). D802.
[G2 General] freinet:
That means for me, no more flashing wild things.

?

I thought the problem would be solved.
[G2 General] 1ceb0x:
I have had two issues with this phone's display - once, the digitizer (i think) got funky and the display started to 'jump' up from the bottom until the middle.. it was like the phone had Parkinson.. and after it got fixed, i got black lines on the right side.

The first issue i forgot from where i had it. The second one was after flashing cm11 unofficial build for d802.

Now i ran LS for more than one month and I have had 0 issues and i have the utmost trust in the developer of this rom that i am sure it is safe for everyone to flash. Cheers!
[G2 General] Formhault:
Screen flickering. If you guys look that up on YouTube, you'll feel the sudden urge to sell your G2s...
[G2 General] momostocker:
Damaged screen with black lines

I have black lines on right side with original screen. I bought a new screen. I powered down my phone which is running rooted ZVD affliction rom. I switched out to the new screen and powered the phone straight into android. The new screen had black lines. My wife has the same phone and doesn't have black lines. I connected my old screen to her phone and it had black lines and so did the new screen I bought. I reattached my wife's screen to her phone and it was flawless. I didn't try her screen on my phone. I don't want to mess her screen up if my phone is somehow damaging the screens. My wife's phone is also on ZVD affliction rom.
[G2 General] HueyT:
You're very brave to open up a perfectly good phone of your wife just to test your bad screens :D

The black lines are from the LCD connection to the phone. If it's off just a little, it'll give you black lines. The working theory is that the heat melts the glue that keeps the LCD connector in place so it shifts or lifts up a little causing the poor connection to the LCD causing black lines. You may want to play around with your purchased new screen at the connection point to see if you can fix the black lines.
[G2 General] Bwangster12:
I wonder if something like this would help the LG G2.

https://play.google.com/store/apps/details?id=com.onexuan.coolify

Or if it's just a placebo effect.
[G2 General] wulsic:
I don't know or it works but if it works then the G2 can still get the issue since we still don't know what exactly causes the lines.
[G2 General] lavafire:
It does work I think, from the reviews I have read it essentially adds in some cpu tweaks that you would find in most dev made kernels (so mostly effective on stock I assume). I am running PA, and I don't have it installed because I don't think it will affect custom kernel much.

---------- Post added at 12:26 AM ---------- Previous post was at 12:23 AM ----------

Thanks for the technical info, that is useful to know. I wonder how many people who had black lines have a case for their G2 and if it is a good idea to take case off during + after flashing (since a lot of apps will be installed back on the phone and generate huge amount of heat).
[G2 General] Chaosz-X:
I don't have the issue myself, knock on wood, but yes, I always do that. Rebooting, switching to ART, recovery, flashing, these things are always done without a case here.
[G2 General] Formhault:
Use a recovery with thermal throttling ffs.
[G2 General] gonzalobasterra:
I just get the black lines. I charged the phone turned off (1st time charging like this) and when I turned on the screen colors in the LG logo looked weird but then went back to normal so I thought there's nothing to worry. But when boot finished... Surprise! Black lines.. It was using CM11 M11. However is on warranty so I reverted to stock. [emoji28]
[G2 General] Chaosz-X:
Alright, time to do this in a better way. Guys, if you have the black lines, please send an e-mail with your IMEI and model number (d800/d801/d802/whatever) as the subject and, and nothing in the mail itself, to g2stats0@gmail.com. I will write a script to keep track of the IMEIs, use the service of LG to request manufacturing date and country where the phone is sold by checking the IMEI, then analyze and process that data to get a bit more insight in which devices are caused by this.

Edit: if you're cool with sending your IMEI ofcourse.
[G2 General] rogisha:
Here is my problem

I have d802 with omni rom

I had few time LG logo melting with PA rom few months ago bit i quickly turned off the device and restored previous good rom

Ok so abt omni

I was trying few different kernels

And none of them booted device

So i tried last one and it was stock aosp kernel

Device started with booting process and there it goes LG logo melting again and this time i had black vertical lines but again i quickly turned off the device and back in twrp i had 2-3 black lines and they disappeared while i was restoring

And somehow my screen is fixed by itself

I think it's all about kernels
[G2 General] Dr AM:
I want to buy this phone but every time I enter this thread I start hating it more and more :(
[G2 General] Formhault:
Or... You can do this. I wrote this (for several times) some time ago in this thread.

"Well, go here : http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?model=LGD800&esn=ADD_IMEI_HERE

Replace model=LGD800 with whatever your device is and ADD_IMEI_HERE with, well, your IMEI."
[G2 General] siggey:
Only a small number of g2 are affected, and the replacement screen cost less than 100 €... And the phone still be better than new others, with a ridiculous street price

_____________________________Write less read more and be smart
[G2 General] MBurns2:
i read a good portion of the thread but i don't have understood one thing: flashing roms can cause this ? i must stay away from modding or from specific sources (4.4.2 or 4.4.4) ?

After reading this thread it seems random (even people on stock rom had this problem..), so maybe it is only an hardware problem ? (not related to rom/kernel..)

Thanks for clarification
[G2 General] 3ig:
Well ..... A friend of mine dropped his phone and got the same black lines.
[G2 General] gonzalobasterra:
I think custom kernels don't have temp. Control capability at the recovery. That's why happens charging the phone turned off or when you're flashing. In my case never have issues until I charged the battery when the phone was turned off causing the terminal overheat and damaging the lcd connections

BTW sorry for my english :)
[G2 General] boyheadkick:
dorimanx's kernel has temp control built in, and blastagator's twrp recovery has the same (as far as i know), if that's what you mean
[G2 General] gonzalobasterra:
Yes, that's what I mean. Do you know if these recoveries had black lines issues too?
[G2 General] Formhault:
Most custom kernels do have thermal throttling. Most recoveries, too.

Besides... charging the phone while it's turned off will not cause it to heat up as much as you'd think. The phone's not stupid, you know... it's got some sort of thermal protection on its own, too, and I doubt any developer went ahead to turn off all thermal protections.

And what the hell, I fast charge my phone (while turned on, with Wi-Fi and sync enabled) all the time, and it hardly gets warm (the current intake doesn't drop, neither).

I'd say flash away, people. Warranty or no warranty. Just stay away from Carbon, PA and CM... they suck anyway. LiquidSmooth and AICP are the way to go (if you're an AOSP fan). Otherwise, your best options are Pardus or CloudyG3. That way, the chances of your screen getting black lines are minimal (except if the phone was manufactured prior to february 2014 or something like that).

---------- Post added at 10:34 PM ---------- Previous post was at 10:32 PM ----------

Recoveries don't. Especially the one boyheadkick mentioned.

While I'm in the recovery, the phone doesn't even get a chance to warm up. A full wipe + ROM and Gapps flash takes less than one minute (AOSP). If I am to flash a stock-based ROM, it's around 1 minute and a bit. Not enough time for the phone to heat up that bad.

If you're backing up and restoring NANDROIDs all the time, sure, heat will build up - especially if the recovery doesn't have thermal throttling.
[G2 General] jal3223:
Why isn't Maudi on the list? ;)
[G2 General] MBurns2:
i saw some people on PA thread complaining about screen damage, do you think that there are correlation between certain roms and screen hardware damage ?

Imo it is really hard something like this..s..
[G2 General] Formhault:
As it has been previously speculated... it could be a combination of both. A little bit of this + a little bit of that... or a bit more of this + nothing at all from that... we don't know for sure.

We do know, however, that some people had the black lines occuring on devices running completely stock (+ no heat up whatsoever), and some people had the black lines occuring right after flashing specific builds of PA, CM or Carbon. So... go figure.

The following are safe to use (and best I've ever tried ; to be taken as a starting ground, not as the only ROMs you should ever look at):

-AOSP : LiquidSmooth / AICP (+ DorimanX kernel)

-stock : Pardus / CloudyG3 (+ RenderBroken / Blackbird kernel)

---------- Post added at 11:04 PM ---------- Previous post was at 11:01 PM ----------

You mean Mahdi? If so, here's your answer : because Mahdi has gone to **** since August. Mahdi ROM is to be taken as is - nothing less, nothing more, meaning if you encounter a bug, chances are it's never gonna get fixed. And guess what : everybody seems to be having issues on Mahdi... especially random reboots.

LiquidSmooth is the new cool kid around the block. Kind of replaces Mahdi, I guess - it's awesome. Hope it doesn't go down too...
[G2 General] MBurns2:
thanks for clarification.

But sorry mate, dorinmax isn't only for stock roms ?and render/blackbird aren't for aosp ? ty
[G2 General] Formhault:
I did specify in my post...
[G2 General] iamterence:
Hey everyone. New G2 user here from the original OG forums. Rooted my device, flashed the test build of PA, and got the goddamn black lines. And from what I'm gathering, if you have the black lines, then you're pretty much SOL, am I right? Jesus, wish I'd have read just a little bit more before I started flashing stuff. I'm not an inexperienced user, but Jesus, some devices are completely crazy.
[G2 General] br0ok1ynb0i:
You can try running the pixel stuck app a few times. If you still have lines, you'll need a screen replacement through warranty.
[G2 General] iamterence:
Unfortunately I bought this phone from a private seller in mint condition for $130 (oh, how it hurts), so no warranty to fall back on. I'm going to keep my OG just in case my OCD about the screen gets too bad and I can't deal with it anymore. Either that, or try to get the screen fixed eventually in due time, or just wait until my upgrade in March for a Nexus 6.
[G2 General] Benztown:
To all PA users:

Did anyone flash a custom kernel right after Rom installation without reboot and still have the melting logo?

The screen victims: could you state your complete setups when posting please? That is: recovery, Rom version, custom flash packages (ie kernels) installed at the time the damage occurred.

I am comparing power management settings of the ramdisks atm and need more data

D802 @ AOSPA 4.4
[G2 General] Formhault:
Well, you paid a darned low ammount of money for it, so I'd say deal with it until March. Depends on how many lines you got, though... 1-2 should be fine. More than 3 would probably drive me nuts.

---------- Post added at 08:52 AM ---------- Previous post was at 08:50 AM ----------

I don't think it really matters.

For crying out loud, stay the hell away from PA. And Carbon. Oh and one guy got the black lines from a CM nightly, as well. So stay away from these ROMs. Besides, there are much better alternatives out there, like LiquidSmooth!!!
[G2 General] Benztown:
Well two options here:

1) stay passive = stay away

2) contribute actively = try to help fix things

I want to choose 2) because that is the whole story behind open source development. If PA is somehow broken for our device we need to fix it.

D802 @ AOSPA 4.6b4
[G2 General] iamterence:
I have about 20-30 lines on the right side. Its pretty bad, but I wanna give this phone a good run, so I'll just deal until March or screen replacement, whichever comes first. Next time, I'll just make it a mission to either get a Nexus or a Moto X. The LGOG was/is such a solid phone with a solid AOSP library, but this G2 really broke me down, man. I've never seen anything like this.

I appreciate the comments though, guys. I'm on Team EOS ROM right now, and I'm just gonna stick with this, even after the screen replacement.

---------- Post added at 03:25 AM ---------- Previous post was at 03:22 AM ----------

Rooted with towelroot, flashed recovery (TWRP 2.7. I believe) with AutoRec, flashed latest PA test build 11-05 with no gapps, lines.

If it means anything, I have some white lines and some black lines as well.
[G2 General] Formhault:
20+ lines... yeah, that's bad. That's gonna interfere with the images and text on the screen...

Well, if you're planning to get the beast that the Nexus 6 is in March, I'd say screw this phone. Hang on in there with these lines for a few more months.

Besides, if you go through the last few pages, you'll see some people ordered replacement screens to repair them theirselves... and they STILL got the black lines. Guess the motherboard is haunted or something. So watch out for that... the last thing you'd want is to spend extra money for nothing. ;)

---------- Post added at 10:03 AM ---------- Previous post was at 10:01 AM ----------

It's just the connector being funky. The lines could just as well be red for all we know.

Did you try a pixel "fixer" app like this?
[G2 General] MBurns2:
yesterday i tried panel app, it said lgd screen. Today it said jdi panel.

How is it possibile???
[G2 General] Formhault:
Lol. Not sure... did you flash anything?
[G2 General] MBurns2:
i don t remember but maybe i flashed slimkat over mahdi. But why my panel changed?
[G2 General] Formhault:
Probably kernel f***ing up the readings. I dunno...
[G2 General] MBurns2:
so i must be worry? i have to do something?ty

p. s: on the app thread they say that it is normal because the output is even base on user input.. so nothing to worry about (i hope)
[G2 General] iamterence:
Quick question: how many of us here are #TeamBlackLines? Did you get a screen replacement, or are you just living with them until you can get it fixed/get a new device? I'm trying my best not to pay attention to them, but its really hard sometimes with such a big, beautiful display, especially while running a beautiful Lollipop theme or something :(
[G2 General] migueldbr:
Just flashed my first rom on my G2 and everything works perfectly with no black lines. Root with ioroot, then autorec to install recovery and then flashed the rom (Optimus G3 rom). I let it cool in between stuff and its all good

On the website to see when it was manufactured, mine says 06.2014
[G2 General] Formhault:
June 2014... that's pretty recent, so chances are if it ever was a hardware issue, the manufacturing is now done right. I guess...
[G2 General] iamterence:
How exactly did you find out the manufacture date of your specific device?
[G2 General] migueldbr:
http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?model=LGD800&esn=ADD_IMEI_HERE

Change "model=LGD800" to your phone and replace "ADD_IMEI_HERE" with your IMEI

thank [MENTION=4129455]Formhault[/MENTION] i got that from his signature

True, but from what i read here before, most people that flash LG based roms with stock kernels rarely have any problem..i dont know=p
[G2 General] iamterence:
I keep getting this error message right here :(
[G2 General] Formhault:
Dunno... Make sure you insert your phone model and IMEI correctly. It must work.
[G2 General] iamterence:
Turns out I was entering the wrong number, so I corrected that, and started getting this instead
[G2 General] Formhault:
Your phone was manufactured some time in April of this year.

Was about to say you should not worry & your phone should be fine. Then I realised "oh wait, this is the guy with a gazillion of black lines". Yup. There goes the theory according to which it's a manufacturing defect. It's most likely a hardware problem that's hit & miss, so it's all about luck. Or a combination of HW + software. Or proof of God. I dunno. F***.
[G2 General] Vollspacken:
Just found 6 stuck pixels (or a bit more because one is pretty big) in about the area where black lines are mostly occuring.

Doesn't bother me that much because on dark grey you can't see them anymore, only on fully black screen. I guess they where not there last few days because i didn't saw them when doing reboots and i just had cpu problems (stucking and so on, synapse just made problems) and reached temps over 70°C. Maybe this could have been the cause...

G2 (D802) produced somewhere in the middle of august 2014 so pretty new device and it's used since nearly 2 months.
[G2 General] br0ok1ynb0i:
Manufacturing date is not even a year, should still be covered under warranty. Recommend you give it a try.

Also recommend whiting out your IMEI number.
[G2 General] Formhault:
Try a pixel fix app. The Play Store is full of them.
[G2 General] sukesh1090:
how common is this problem of damaged screen??I want to buy LG G2 but i am held back because of this problem. do the phones manufactured in recent batches are also plagued by this problem??
[G2 General] razrzxcvbnm:
Just want to inform you guys that you can check the production & release date of your motherboards, etc by downloading an app at Play Store called "LG Phone From". No need to edit links then type in your IMEI's.
[G2 General] Formhault:
Not sure. Up until recently, it was thought that the more recent the phone is, the less it is prone to screen issues.

Well... look in the previous pages. G2 manufactured in 2014's summer and already got a lot of black lines. Go figure :eek:

If you can find a G2 with warranty, go for it. If you can't... better not take any chances :/

It's old and here in Chile a replacement would cost about 270 US. I'll have to deal with it until I have the money
[G2 General] Formhault:
You're screwed...

---------- Post added at 09:31 AM ---------- Previous post was at 09:31 AM ----------

He just said he has no warranty.
[G2 General] khaytsus:
Flickering could just be ROM issues. If you're seeing spurious noise here and there and usually goes away after a reboot, definitely a ROM issue. I have this randomly on AOKP but I've mostly attributed it to use of insanely large wallpaper.. I download wallpaper from various astronomy sources and sometimes I don't realize they're super large.. One particular picture that EVERY time it came up (random wallpaper script in Tasker) the screen would start flickering badly. Turned out it was like 8k pixels wide ;)

Anyway, I think it happens outside of that too, but not very often. So if that's what you're seeing, it's not a hardware problem.

If you're seeing lines flickering or something, I dunno about that.
[G2 General] Formhault:
It is not ROM related...
[G2 General] khaytsus:
The best thing to do when you don't know something is to not comment on it. Please don't pipe in with misinformation.
[G2 General] Formhault:
Misinformation? Yeah, you're full of it.

Otherwise... I guess these guys are lying. And [MENTION=2688060]1ceb0x[/MENTION], too (he TOT`ed back to stock and the screen flickering issue was still present).
[G2 General] khaytsus:
Now, read what I said again.

The video is not "flickering".

But yes, I forget, you can't be argued with. You're always right., etc. This is my last response.
[G2 General] Formhault:
Good. Make sure you get your eyes and information source checked until you decide to return.
[G2 General] 1ceb0x:
that video is screen flicker all right.

it is not due to a large wallpaper, live wallpaper, rom, kernel, maria theresa or jesus christ.

it is simply a.hardware.failure.

I have had it and the only fix was to get it repaired by the service center.

there is an old saying - "when 2 people tell you that you are drunk, you go to bed."

PS - i had it on stock rom.
[G2 General] khaytsus:
So I'll respond to you I suppose.. Let me quote myself. Once more. Perhaps someone will read it this time? I'll even emphasize, just in case you're too busy "being right" to pay attention.

So do you call what you had/have flickering? Cool. It's certainly something screwed up. Not the same thing as I was talking about.

Are either of us talking about the same thing as the person who originally asked? Who knows.
[G2 General] Formhault:
[MENTION=925627]khaytsus[/MENTION] You're 100% correct. Now, can you please stop providing further input, like you bragged you'd do 4 posts ago?

The guy is complaining about screen flickering and you say "spurious noise here and there"?!?!
