[G2 General] :
that's cause everyone is in recovery and rebooting a lot more then on stock. Doesn't necessary mean aosp is/has the bug or only triggers it. But does make it likely.

It seems certain commits to certain roms made it occur a lot more. Those have been retracted, mostly. Mahdi for one, I still have to see a single case.

A likely suspect, recovery itself might be eliminated with dr 87s twrp recovery, of which the changes might be incorporated in the future in Dees troys twrp.

Bootup/bootdown process might be eliminated by not rebooting to much, or when phone is already hot.

might if sudden high heat resulting from unprotected recovery, bootup/bootdown is what causes it. Even in combination perhaps with certain commits that definitely seemed to make it worse.

that being said, it might also be wise to not switch of thermal throttling when ROM is running.
[G2 General] Formhault:
Although the majority of people who have screen issues is on the AOSP side... I doubt the problem is AOSP related. There have been reports of people starting to have this issue being stock, or flashing stock, so... I guess it's just that more people like AOSP :silly:.
[G2 General] Compass Linux:
Funny, I've got 6 vertical lines too. :highfive:

It's best to flash a TOT so that the partition(s) where the root flag is will get wiped out 100%. Oh, and go to the OP and please add to the survey.

Is there a way to get this thing back to stock enough to be able to return it to att?

Yes, here.

An original return he solves 100% wrong?

ps: sorry for my english.
[G2 General] Formhault:
Is there any way to check what screen hardware revision our phones have? Like from that 3845#*802# service mode (perhaps there is such an option which I am not seeing)?
[G2 General] borjaox:
I have got the non-permanent white screen/lines again after flashing the two last Carbon Rom nightlies and both times I have noticed that the phone got extremely hot in a little area that is just at the upper right of the LG logo in the front of the phone (just below the screen).

Looking at this teardown, I would say that this area corresponds to the LCD connector.
[G2 General] didhiy:
Choose setting > system info

Afaik white line issue related to jdi panel that solved by flashing proper kernel for it
[G2 General] Formhault:
You mean "Version info"?

Anyway, looks like my Factory Version is smtb.smth.smth-MAR-06-2014, so... I take that is the manufacturing date.

HW Rev is still 1.0 though, lol. :eek:
[G2 General] mor_1228:
i have ldg = LG panel

do i need to worry ?
[G2 General] borjaox:
No that white lines, just the ones that appear at the LG boot screen. After cooldown and reboot the lines are gone and no white lines into the OS itself.

Some users have reported these lines appearing during boot before experiencing permanent lines. The fact that I am getting these lines while the phone is very hot is consistent with some theories on this thread that link high temps in certain components to permanent screen damage.
[G2 General] Formhault:
The fact that your phone has a LDG panel doesn't mean it's 100% safe. Both LDG and JDI panels seem to be affected, so... it's just a matter of luck, I guess...

---------- Post added at 04:57 PM ---------- Previous post was at 04:55 PM ----------

I was browsing the web via Wi-Fi, downloading a bunch of large files. All this, while charging. At some point, I was unable to raise the brightness above 80% due to temperature (checked, the CPU was >75 Celsius degrees and the top side of the phone was hot to the touch). 30 minutes later... no lines on the screen. Rebooted => no lines on the screen. Not sure if the temperature wasn't high enough to cause any damage or I am safe... :silly:
[G2 General] NicoC72:
Take a look at the results from that survey I made in the OP. JDI panels seem to be safer, but not immune.
[G2 General] :
That's funny because I heard it was the exact opposite. The lgd is safer but not immune.
[G2 General] Formhault:
Perhaps it's just the fact that less people have JDI displays...

And hey. Maybe newer phones are immune! Like mine, for example - made on 6th of March 2014, apparently (so it's a newer batch, not from last year or January or whatever), and I haven't got the lines yet. I rooted, rebooted recovery, did some funky stuff to get it hot and still no problems. :confused:
[G2 General] :
Yeah I know same here and I flash 4-5 times a day before I settled on mahdi
[G2 General] musashihatred:

G2
[G2 General] Formhault:
It must be a hardware issue. I mean it makes sense, right? Previous hardware revisions had the issue, LG figured their **** out and fixed it. If anyone whose phone was made in 2014 gets this problem... f*** LG, and I'm out of manufacturers from which to choose a phone :) and I must get an iPhone :) :silly:.
[G2 General] wulsic:
I think they also added something for cooling i guess. I hope my g2 will not have that problem, You can try else One plus one(Oppo) Xiaomi or those kind of company's maybe or a phone with flyme os also nice. Well more pixels more hd More issues if you ask me.
[G2 General] Regash:
how do i now when is my phone made?
[G2 General] Formhault:
1) Open Dialer

2) Type in 3845#*802# (if you have a D802, otherwise type 800 if you have a D800 and so on)

3) Go to Settings -> Version Info -> Factory Version.

Mine says "LGD802AT-00-V20b-EUR-XX-MAR-06-2014", which obviously means my phone is an international (XX, if the naming scheme is the same as with Samsung) D802 which was manufactured on 6th of March, 2014.

Funny... Under "HW Version" it said Rev1.0 earlier today. Now, after rooting and downgrading bootloader to flash custom recovery, it says Rev1.1 :eek: :confused: :laugh:

---------- Post added at 10:06 PM ---------- Previous post was at 10:04 PM ----------

Something for cooling? Perhaps better thermal paste on components... I dunno...

I wanted the OnePlus One, but their invitation system sucks. Plus, my country isn't on the list of places they ship to :). And Oppo... I don't trust they make that good phones which work fine on European carriers, so... LG G2 it is.

I hope my G2 doesn't get the screen problem, too. I mean who doesn't...
[G2 General] Skizzy034:
I tried going into that menu to check the HW version and when I get to version info the phone freezes and I can't scroll down to check.
[G2 General] siankatabg:
I think that this date(in the hidden menu) is for the software release,not for the device.

Maybe this post will help you:
[G2 General] reas0n:
because it IS. for the device there is Rev. on original box and in hidden menu, I have Rev 1.1 and didn't have any permament lines
[G2 General] ales100i:
No you are wrong. 6.3.2014 is the date when current software version 20b was made. Mine says the same. Also saying that only older phones are affected by this issue is wrong also. I have a new phone, which was bought 1 month ago and came with 4.4.2 preinstalled, which means it was made in march or even later. And i got the lines anyway. It happened after a flash of Eos. And it was the first flash of the day after being on mahdi rom for a week. And the phone did not get hot at all. So all speculations are probably wrong and we are no closer to a solution.
[G2 General] :
Can't sit there and say everyone is wrong. You obviously don't know what your talking about. Plus newer version seem to not get lines. I doubt you did.

---------- Post added at 07:58 PM ---------- Previous post was at 07:57 PM ----------

[G2 General] siankatabg:
Where on the box? Mine is produced on 31 March 2014 and it comes with kit Kat pre-installed,but service menu says rev.1.0.
[G2 General] Formhault:

How do you know yours was made on 31st of March?
[G2 General] :
Yeah my bad it's just not right for him to call everyone wrong
[G2 General] ales100i:
Ok. First of calm down. Nobody is attacking you, so just chill. We are all here on the same boat. I am not saying everything is wrong, but this two statements are, sorry. Maybe heat could be an issue, but it was not a problem with me. And you can believe what you want, but I got the lines and also already got the screen repaired and I have a new phone. One thing I did notice though is that after replacement my touch is more responsive than it was before the repair (the service paper said they changed the screen and also the touch digitizer). So maybe this is something to consider. Maybe some phones had slopy manufacturing when asembled and they get easier detached somehow. I don't know. Maybe it is connected somehow. So what do you people that got new screens, do you have better touch response? And those who have black lines, do you have problems with touch as I did?
[G2 General] Formhault:
How exactly did you get lines? After a gaming session, rebooted, and bam... or... elaborate! :D
[G2 General] :
I gotta say that when the phone was made has something to do with it also. You may not be attacking me but sitting there saying people's statement is another thing. It's faulty equipment. And yes the older the phone the more chance of an issue. Look at the s5 the firsts one released there were speaker issues. I think the new phones have less issues like stated above because LG found the issue and resolved it. Doesn't mean that a few bad phones like yours
[G2 General] ales100i:
As I said. I was on Mahdi for a week and was satisfied with it. But then one afternoon I was bored and was reading this forum. Noticed a new rom I did not know before - EOS. downloaded the rom and flashed it. After the reboot LG logo was weird color and when it finished booting the lines were already there, about 10 of them. Tried rebooting, flashing back Mahdi, kdz-ing, nothing helped. So I took it for repair. The problem was, that although I flashed kdz, download mode still said rooted. So I was prepared that the service center will not recognise my warranty. But they did. They repaired it in 4-5 days. Was surprised how fast it went. After I picked the phone up, they said it is a known problem and it was not the first time, they did this repair.
[G2 General] Formhault:
What recovery were you using? Normal TWRP or dr87's modded TWRP?
[G2 General] :
You say your phone wasn't hot when this happened. Your phone can still be hot internally and you not be aware. This is a heat issue. You may have not felt it but it is.
[G2 General] ales100i:
There was no modded recovery then yet. I was on Phil's recovery.

This thing is so very weird to me. I am flashing roms since 2008, and was at one time a crack flasher. So I flashed probably more than 1000 roms on 10 different devices. And I never had a single problem. Even more, I never read in any threads on all those devices, that a rom could damage the display. This has no logic whatsoever. First time in my Android life, I am afraid to root my phone. I am sure that if I bring the device for repair again, they will not be so friendly. So I am waiting for something to happen here in this thread. That is why I try giving as much feedback as possible. My fingers are itching and I want to try 4.4.4. rom, but as said, I'm afraid now.
[G2 General] Formhault:
The heat buildup is probably what killed the connections, hence causing the lines. PhilZ and normal TWRP don't have thermal throttling, like dr87's TWRP.

I know, right?! I've had 10 Android devices so far (this G2 would be the 11th) and I never had any problems with them. At least not problems that emerged from rooting, flashing or something like that.

I know there's one guy who got his display filled with lines when he was just wandering about in stock recovery (so everything stock, nothing modified), but still...

I don't think you've got anything else to be afraid of. They replaced the display, they admitted it was a fault on their end, so you got a problem-free display now.

I'm thinking of selling this device NOW, while the display is band-less... :(
[G2 General] wulsic:
I don't know or somebody did it before but i just tweeted a message to LG regarding to the LG G2 screen and i will start a discussion about the Rev and like that why it is like that and what it means according to them. So i will wait till tomorrow and if i get a response back i will share it.

Cause the default Emailsendingto LG requires Full name adress phone number so no...
[G2 General] ales100i:
What does band-less mean? I really like the device. It is the best one I owned. But I love flashing as well, it is the best part of Android. So I may also sell it and buy something flash friendlier. [emoji4]
[G2 General] Formhault:
Band-less, as in without bands. You know, the black bands (lines)...

I don't have anything else to buy. The Note 3 sucks (it's just AMOLED that sucks, actually), the G3 is too expensive right now, and what else is there left for me to buy... I'd have bought the Nexus 5 if it had better battery life.

I guess I'll just have to pray I don't get black lines... :eek:
[G2 General] :
This device is flash friendly enough. If your scared to flash your device then obviously flashing isn't for you. That's the perks of flashing. This kind of stuff happens. Other devices have issues with flashing you can't be afraid.
[G2 General] wulsic:
Yeah i also think AmoLed sucks also because of the colors i dont likebut also because of the screen burns in. I also had it by the S2 you could see the SMS application and keyboard by my phone if you had a white wallpaper.

G3 is expensive and yh you can try the g3 mini lol.

I also have to pray that i don't get black lines or just change my mind for buying a device but i like the LG UI so much and its not the whole time the same development as on Nexus5 Only aosp like roms. I just have to wait for the message from LG and i will inform everybody when i get a message regarding to that and if they have fixed it and what they did for it like placing somethingbetween idk. Maybe we need to see also a dissassemble video from the beginning when the G2 got shipped and a late dissassemblevideo on youtube.
[G2 General] ales100i:
Yes you are probably right. I am just paranoid I guess, since it is first time I had problems. I will give in to temptation probably sooner than later and be back on flashing train. I just wish we could come to the bottom of this. I was pushing the LG guys at repair center to tell me, what actually caused this. And they did not want to say. They just said: faulty screen. And in the end we will maybe discover that actually this was the case: Bad quality of some screens.
[G2 General] :
Flash the new Mahdi you won't be disappointed. It's the best.
[G2 General] didhiy:
It freezes in cloudyfa g3, was displayed correctly in stock

I think you misunderstood i think he means after flashing a stock ROM not after flashing from a stock rom to a ASOP im on latest carbon 01/06 802 and on dr87 fixed roatation bare in mind the rotation doesnt work im scared to do anything! I want to flash back to stock and play it safe

Anyone got any advice to people already running these roms should i not update baseband shoudl i go back to stock? or should i just leave it as it is? people are saying they have just rebooted and got the screen thing :/
[G2 General] Giocarro:
^ this. Also, there are no reports of black lines on stock-based ROMs, so it doesn't look like faulty hardware is the case here.
[G2 General] Compass Linux:
There is, regrettably. And if I understood that post correctly, the person went from Stock -> Stock KitKat OTA.

Compass.
[G2 General] Compass Linux:
Since we don't know what is triggering this issue, I won't recommend doing this or that. Post #56 claims his OTA from Sprint gave him the black lines.

I'd leave it alone for now until we have more information.

Compass.
[G2 General] DrugsBunny:
maybe it has to do with the new KK baseband everyone is flashing?
[G2 General] Compass Linux:
It could be, but Post #56 doesn't mention if he was on pure stock or not. Since it wasn't mentioned any custom flashing, I'm assuming (and taking the risk of being wrong, of course) that Sprint's OTA from JellyBean to KitKat triggered this issue.

Compass.
[G2 General] DREWHAMM974:
Stock OTA. I had used tot to go back completely stock to get the OTA. Only thing changed is I was rooted. Took OTA and first boot right side of screen had multiple black lines. At the time it had not been mentioned so I thought it was just hardware and then it started happening to multiple people in the past couple days.
[G2 General] bps119:
Shouldn't be the baseband as mine occurred in February before I'd ever run that baseband. It also happened to two others about that same time, and at least one other before that even.
[G2 General] MRobbo80:
Think I will stay only on stock based roms for the time being had my fair share of playing with aosp cm aokp based roms, I like me g2 to much don't want to %/÷× my screen.
[G2 General] Compass Linux:
Flashing a TOT doesn't replace all the partitions. I wish there was an easy way to do it so we could test it.

And thanks for clarifying.

Compass.
[G2 General] DREWHAMM974:
True but had went from stock based ROM to tot. So no AOSP on that device before the issue.
[G2 General] Jank4AU:
Has anyone tried using the LG Tool to go totally back to stock? I mean that should totally wipe everything and make it just like when it came off the assembly line, right?
[G2 General] JRJ442:
I doubt that would fix it. A hosed display is a hosed display. If you have black lines even in recovery, that's a serious issue. I don't see how any amount of restoring would fix that.
[G2 General] Jank4AU:
Just to say we've exhausted all options for a fix of the broken ones....
[G2 General] JackpotClavin:
I don't have the issue, but took interest in the issue. It could be due to faulty hardware, but I wonder if this commit is related to the overheating: https://github.com/AOSPA-legacy/and...mmit/a1cc5645b5557780e30d28c38b3ec6b056b5e754

The earliest post I could find related to the black line banding was from January 3rd, 2014. That git commit was authored December 14th, and was the only one I could find that could be tied to overheating. I can't find the original git branch that that commit came from though.
[G2 General] JRJ442:
Here's dr87's take on it. This post was linked earlier in the thread by [MENTION=5461670]bachera[/MENTION] but I'm gonna repost the content for everyone to see and maybe get some opinions on it. Especially [MENTION=3727492]JackpotClavin[/MENTION]. What do you think about this?

I have not changed the kernel (anything besides small gov fixes, etc) since beta and this has never been reported on my kernel before. I do not use screen commits. Which rom did you come from, whats the md5 of the patch you are using? JDI panel or not?

Edit: My best understanding of the black line issue is that is created by kernels that have changed parts of the screen that shouldn't be changed. Refresh rates, Certain Vsync code, basically anything that effects the display (a lot of these commits are available in the new CAF repos and can be easily pulled into a kernel) Once the clocks are changed on the display, some seem to be persistent and can cause immediate or delayed damage to the screen. If these lines are 100% permanent is unknown, I've heard about them going away by flashing certain kernels or updating the screen firmware with dialer code on stock roms. I have also heard of the lines appearing when switching off the kernel that had changed the display setting. I do not mess with any of these commits and never will.
[G2 General] fordmanck:
Subscribing. I funked mine up today on AICP.
[G2 General] arifqur:
From all the posts that I have read, it seems that only the lgd display panel is affected and not the jdi one.

Can anyone with a jdi panel who has had this issue come forward and clarify this theory.
[G2 General] Formhault:
I know what you mean. That's the reason why I no longer want an AMOLED device... at least not until AMOLED is burn-ins-free (which may never happen).

What? No... You know, there's a reason why I'm staying away from AMOLEDs. While AMOLED burn-in and colour inhomogeneity is still better than having black lines (or is it? it used to drive me nuts), knowing the G2 has this issue, it'll be hard for me to consider the G3 next year (it sure looks like the most awesome thing ever).

You really think LG will tell you? They'll most probably say something like "it's the display, get an upgrade". Same happened with Samsung, when they admitted they f***ed up with the N7000 - black crush, if you know. All they said was "problem fixed in newer models"... like... f*** you, customer, you ain't getting the kernel update with calibration fix.
[G2 General] Compass Linux:
Yes, flashing the proper TOT for your version will return your phone to pure stock, ready for warranty.

[G2 General] DarkmanXTC:
I assume its the normal twrp, i let flashify download it for me. i normally stay away from the hacked recoveries unless a rom says you need this specific one.
[G2 General] Skizzy034:
I love my G2. Its my favorite smartphone released yet. I have had a few Note 3's and none of them had burn in. Not once. Also, the colors looked fine. The screen was vibrant. You simply can't compare the faults of an older phone like the S2 to something new like the Note 3. It's like the people who won't use Android because of an experience they had on 2.0. Be objective.
[G2 General] Formhault:
I had 5 Galaxy S4s. One 10 months old, 4 brand new (replaced by warranty). 3 of the 4 brand new ones had screens uglier than the 10 months old one. Your Note(s) definetly had issues (maybe not as bad as any other S4 out there). Your eyes just aren't trained and/or obsessed like mine, that's all :p.

I thought that with the S5, things will be different... Go in any Samsung showroom and look at multiple S5 phones. What will you see? Burn-ins and inconsistency all over the screens...
[G2 General] wulsic:
Yeah thats true And i still didnt get a message back from LG Webcare... They just ignore me and answer to all the other questions. The NL LG really sucks. But im sure i will buy the G2 and just hope i dont get black lines.

EDIT: After i replied again to them about that they must stop ignorng me then they reacted and they were talkingthat they are doing it on order... But they said

It is not known as a common problem to us. And that i can just buy the G2 I replied once again. And on my Ignore message they said See Earlier message! with a ! very nice help.
