Purely speculations, just like this thread.

WE all use the same recoveries in AOSP or stock, so how can heat affect the recovery of one and not the other?

You listed everything that could have gone wrong with the screen, what is there left to figured out?

Lets put some statistics into this to make this more legit.

25% commit fault

25% AOSP fault

25% recoveries fault

25% panel fault

I've own phones that get way hotter than this on a DAILY basis, my G2 gets hot sometimes, but never encountered it getting that hot when I'm backup/wiping/flashing times and times again. We have DEVS that flash and reflash test roms thousands of times, dont you think their phones would be the first to go?

I think this is simply manufacture defect and it took a while for the defect to show itself. We can sit here and think of why it is happening, but the end of the day everything that have been thrown out in this thread have been non effective. What is next? only affects people that put it in their pocket? Only affects people living close to the equator?

Yeah I was flashing 2-3 ROMS a day till I found that I liked Beanstalk the best, guess I'll keep rolling the dice lol better than when I was on my Rezound as a flash addict ;)

This thread might seem pointless because we haven't come to a conclusion yet, but we'll never get there without this exchange of information. It isn't guaranteed that we'll have a definitive answer, of course, but that won't stop us from trying.

Although the number of devices with this problem is low, I hope LG has taken notice so this doesn't happen to the G3 and future devices.

[G2 General] easyguy:
The harm is not in the thread, but in the misinformations. So much so that in the early beginning some were pointing fingers at a certain rom and the dev behinds it, load and behold almost every rom experienced the problem now. Now in every rom thread people are running around scare ****less to flash. Even now there are new guesses, now its the recoveries. Sometimes being proactive is keeping quiet until something concrete is discovered, does no good scarying uninformed people.

If opinions are like assholes, we both have a lot of them.

Your intention was good in creating this thread. We all knows LG gave us crappy lcd screens because of the randoms white lines i believe most of us have encountered. but instead of blaming LG, some have turned inward to blame each other.
[G2 General] bps119:
Accusations were flying before the thread was started. People always want something to blame. Only thing that matters now is that people are getting together to see if we can keep from having this happen to others. If we figure it out, great. If we don't, at least we tried.
[G2 General] fordmanck:
It's pointless if you haven't had it happen to you.
[G2 General] butler360:
Part of the reason we know that now is because of this thread...
[G2 General] easyguy:
All good points.

I still dont see a solution to this as this is becoming clearer as a manufacture defect. I've had two lcd tvs developed some sort of lines without any upgrades or tempering so i do know that these things are fragile and stuff like that do happen.

Also the devs might get tired of getting asked if their roms will produce lines, which in turn makes the devs annoyed and end support for our phone.

Are we trying to fix something that is not broken?

Ill end this convo at that.
[G2 General] randy6644:
as what I have observed, Chinese users dont seem to have this problem. they do flash roms,more like cloudyfas than others. and some flash aosp build however. they have other issues as screen shaking instead of black lines.
[G2 General] maxniper:
Sorry for the nood question, i'm new to LG G2 D802, my screen is screen shaking some times and some times the screen not responding, i turn the creen off then turn on and is ok again, should i be care about it and go to the store for change to a new one? i ask that because i have only this week more taht i can force the store to have a new one.
[G2 General] lacus:
couldnt agree more, i have said that the blame is on LG in this thread long ago
[G2 General] randy6644:
yes, you should! its only the beginning, its been proved that its a hardware issue. they fixed it only when they got a new screen replaced.
[G2 General] randy6644:
I gave you the reply but forgot to quote it.I dont know if you would see it without the quotation, so I am doing it again.
[G2 General] NisseGurra:
Its NOT an hardware fault, its the SW that kills our screens...

[G2 General] Compass Linux:
Judging from the numbers, only a few people have been affected.

If you're one of the unlucky ones like me, I hope you have at least 12 months warranty! :fingers-crossed:

Compass.
[G2 General] :
Guys, its science, point fingers and eliminate, pure science with not much definitive data :)

Because the amount increased on certain roms, it points to possible software causes/triggers. Because its only a few if its purely software that means its rare. However it does seem hardware has some possible weakness/susceptible. Like dr said all devices are different :)

Who cares, hope his recoveries prevent the issue to ever surface again :)
[G2 General] randy6644:
yet
[G2 General] :
Lol, same here, at least not permanent ones, knock on wood
[G2 General] :
I don't think it will. With All the flashing I done it should have happened.
[G2 General] Bugox:
So why dont you just leave? There are some people with the black lines who try to find out why. Please let them spend their time how they want.

You obviously dont have the same goal so just leave. Thx

Screen replacement

I got black lines previously and got the screen replaced so will i get the same problem again?
[G2 General] technotika:
Just happened over here folks, I flashed EOS the revival D802 nightly dated 17062014 (coming from same ROM dated about 06062014) - merky LG logo on boot then the black lines 1 cm thick on the right hand side. Tried (before reading this thread) nandroid restores, tot's, dkz's & firmware touch u/g - same. So el kaput. Cant complain, knew the risks, just didn't think it would happen to me lol. Had a feeling it was bad news when I could just make out the lines in download mode.
[G2 General] :
first off I am not going to leave. I am here to help figure out whats the cause, and secondly no need for a response from you like that. This is a public forum.
[G2 General] Compass Linux:
If you're still under warranty send it for repair after returning it fully to stock.

As far as I know, there haven't been any reports of screen replacements having the same problem. If it does happen to you, I'd suggest sending it back again for repair. Where I live the repair service itself has its own warranty.

[G2 General] easyguy:
Dont you think if its software that is triggering it, more people should have the issue? The rom you are talking about is PA, but as I calculated that rom is the most popular rom, of course the amount is going to be higher than any other rom.

Dr also said it was certain commits and said he didn't include any of those, which turns out to not being a commits issue, because his rom was being affected too. Even some of the stock roms were affected.

I think its the LCD screen themselves, it took time for it to rear its ugly head.

I hope you guys can come up with something, but I'm not holding my breath.

That is a healthy discussion, if someone disagrees with you, kick them out? :laugh:

Prove to me that it's a software issue. Prove to me that he is wrong.

My prediction, this thread will get a sprinkle of people having the screen issue, but will slowly fade away as time goes on and nothing have been figured out yet.

I hope that you guys figured it out as we all have an G2 in here. :highfive:
[G2 General] velveteen71:
I had the black lines appear last Friday. They are 4 very thin lines on the extreme right-hand of the display.

Just now, I have a new line, about 2 cm to the left of the group of 4. I hope I don't keep getting more and more lines. Seems to indicate that it's getting worse.
[G2 General] :
Its possible and plausible the number game applies, more flash rom x so more cases to be likely there. Considering we don't have factual proof its hard to prove anything.

We cannot ignore though that certain likely causes for these malfunctions is heat, and most likely point of it occurring is during unprotected recovery. It does make the case for a protected recovery more sincere. Especially since other recoveries exist with the heat protection. For short and longterm damage risk mitigation.

Dr is making these. So dont worry Its something haha
[G2 General] easyguy:
Why not send it in? what rom were you using when that happened? When did you purchased it and did you noticed your phone getting hot a lot? Usually with LCD lines issues, the lines will progress with more lines, if you had an LCD TV go bad on you, you would notice the same thing.

Sometimes TV issues can be fixed with changing the processing chip/board, sometimes its the panel. Hence another reason why I think it is hardware.
[G2 General] velveteen71:
No warranty: I traded my Nexus 5 for it. I'm running PA. The lines occurred after installing RC1, using the OTA update. I did notice that it seemed to be hotter than normal.

Guess I'll have to call a fixit shop and check their pricing.
[G2 General] easyguy:
It is possible, but very unlikely, I've had other phones before samsung, LG, HTC and those phones used to cook my hands/fingers when they heat up. You would think that those phones would have developed those lines a long time ago but they never did.

My LG never get that hot.

would a phone ever get that hot during recovery? ok I've backup, flash, wiped, reflash because I flashed something wrong, flash other kernels, never noticed it getting that hot where I think it can do damage to the phone.

I'm a very pessimistic person as you can tell, this is in no way shape or form that I dont want you guys to succeed in finding the cause of all this.
[G2 General] :
Even stock seems to be missing recovery heat mitigation. Sure its weak hardware it cant deal with it :) makes one wonder why certain recoveries exist with those heat failsaves. Hardware only failure, I just dont believe it.
[G2 General] easyguy:
You are still under warranty. unless the phone was stolen by the previous owner it is still under the 1 year of it debuting. Just tell them you got it as a gift and dont have a receipt.
[G2 General] Compass Linux:
It was posted in this thread one place where it costs almost USD$80 (glass screen + panel) for the D800 AT&T version (forgot about that). You might find a better price if you search the internet.

Forget the above if under warranty. :)

[G2 General] easyguy:
Just taking the screen off and having to glue? the screen back on I think is a nightmare for me. Hope I dont have to do that....
[G2 General] Compass Linux:
Not something I'd do either.

If not under warranty, I'd ask the repair store how much the component + labour would cost. If the component would be too much over the USD$80 then I'd buy from the internet and only pay for the labour.

Compass.
[G2 General] :
Then hope its not hardware cause ;)
[G2 General] velveteen71:
I just called LG Canada. I explained that I don't have the receipt...said it was a gift. They said they can't help me unless I have the receipt. Otherwise, will have to pay out of pocket.

[G2 General] Compass Linux:
If you cannot get your hands on a copy of the receipt, I have another idea, albeit risky.

Search ebay or the likes for a broken LG G2 (same model as yours) that doesn't have a issue with the screen/panel. Then put it in yours if possible.

^^^ Guys, is it possible that he can replace the screen + panel that way? ^^^

[G2 General] DREWHAMM974:
You are all thinking that replacing a screen is a almost impossible task only the most qualified professional can do and that assumption can't be further from the truth. A couple screws, prying the back cover of with a guitar pick, pushing the screen out /pulling with a auction cup after heating with hair dryer after disconnecting a couple connector threads. Reverse the procedure to put it back on. Most come with adhesive already on the back of the panel that you remove a piece of plastic from like a screen protector to place it back in place.

If you can use a screwdriver, pop a couple plastic clips worth a plastic pry tool / guitar pick, use a hair dryer, and stick a sticker on something you can do it. There are videos on YouTube showing the exact procedure as well.

Tell them its their damn fault for putting a phone out with a manufacturer defect and to escalate the issue to a manager if you have to. Or call back, eventually someone will give in. Tell them this phone comes with a 1 year warranty and it has not been a year since the phone been out. Tell them to stand by their product, tell them, who the hell keeps a receipt for over 8 months? Tell them anything that can get you a repaired. Once I got 3 Asus laptop repaired without getting asked for a receipt. Or you can tell them you bought from such and such and you lost the receipt. Try all that before you go the self replacement route.

Have never replace a screen so my imagination got the best of me. Did not know they come with self adhesives.

@ all Users with the black lines problem. Have you use a flip cover or other cover? I have use a flip cover. The cover could also provide a heat trouble.

I have a TPU cover from http://dx.com/

My device wasn't hot when the black lines appeared but I believe that my G2 was almost bust, so I don't think the cover was important in my case.

Its not the covers/cases. I have a case and I put my phone in my pants 8hrs+ a day. You guys never had phones where they heat up all the time? Am I the only one? lol

They built phones knowing that will heat up, they built phones to survive at a certain degree. They dont just release a phone without putting through physical tests.

I can understand if our phone is known to have heat issues, but out of all the roms threads and issues threads, heat isn't even in the top 10 issues with our phone.
[G2 General] bps119:
I wonder if anyone with the issue who hasn't already sent the device back could open it up and play around with the connectors to see if the lines go away.

You can obviously read so explain me one thing, why dont you?
[G2 General] mrdunn:
Could you kindly word it in a nicer way? Thank you.
[G2 General] erto90:
Ok but is not ok to be rude,because, for my personal way of thinking, you are in the wrong road

And my answer was focused on that, on what you were able to reply

I think it is not related to flash rom or what..

If can happens also at reboot, on sotck rom, the issue must be searched there

Is obvious that flashing a rom means a reboot or more, triggering the thing..

I'm not able to read and understand logcats, but a simple reboot log can give us lot of infos.. Maybe is something related to cpu freq or something similar. Can be also some sort of hardware checking, a protection... Everything

As stated, i'm not able to do anything with my knowledge, but i'm sure the solution is on the reboot method and not in the flash process

And again,post pics of who has been affected by this thing, because is simple to write, the world is full of haters

Everyone own a camera or another phone, somyou are pleased to start to post the pic of damaged screen

And again, why the only appears on right side? Always on right.. Said this, can be an other hardware (located on right side of display, ie left if saw by back) fail, insted of the screen itself?

Maybe that hardware burn something related to the screen and the lines appears..

Just my 2 cents
[G2 General] Compass Linux:
Check the developers post in the OP. :good:

Compass.
[G2 General] erto90:
I read all and some are inconsistent..

When Dr said that can be because of 4.2 bootloader on 4.4 firmware or what is, has forgot that autoprime had the problem running stock rom with stock recovery.. So. Or was a auto fail case not related to what you think is the cause, or the culprit is an other thing..

Again, for what I understood seems that newer phone are more safe, maybe due to a better revision. But how we can check that? So far all your reply are only read here and there without reading what users say and think, there is nothing definitive, only theories

Of course thanks to all involved but I think only LG know the truth. At least, for now..

Would be nice to know if the problem can happens again after the return from assistance.. This would clarify lot of things..

[G2 General] turbo8687:
I havent had any permanent damage so far, but I'm worried every time I reboot it.

Using TWRP 2.7 on D803, with lgd panel, tried a clean flash from may 15th PA beta5 to may 20th. flashed 4.4.2 mini modular GApps. After flashing, phone rebooted, showing lg logo as usual. Then it sort of faded and had a greenish streaked up and down the screen, same width as the logo. I used the buttons to reset instantly and then it stayed at the PA boot animation, but no screen problem this time. Went back to may 15th build.

Phone was unstable, lagging and freezing frequently, so I wanted to do another clean flash. Cleared everything, reflashed the may 15th beta 5 and same gapps, on first reboot, same problem with streak, but there was a white horizontal line at the top and the logo seemed shifted. Rebooted, it was fine again.

Needed to reflash gapps, so just flashed it I'm TWRP and after the reboot, the screen appeared exactly as it has on first boot, then its fine after.

No permanent damage, id like to try a safer rom, or go back to stock, but I read that it can happen after leaving PA, so I guess I just have to keep it how it is. Each reboot is so stressful though, never sure what'll happen.
[G2 General] ephumuris:
I think I may have been the first person to report this issue a few months ago. I had to get a replacement. I think I was on a stock based rom can't remember now. It was fine until I flashed a new kernel and then this lines appeared. Couldn't get rid of them. I assumed it was because I flashed an AOSP based kernel when I was using a stock based ROM. Really need to dig up my post.
[G2 General] lazer77:
FWIW (probably nothing), I had been on PA prior, never having this issue. Never took any OTAs for ROM or GApps. Always updated myself through TWRP. When I first flashed PA, I flashed the partitions provided by houstonn along with the KK baseband from Cloudyfa. Have since moved on to Mahdi, still no issues currently.

[G2 General] crackerjack9249:
Now something I've noticed similar most the Roms having the issues have you flash the official kk modem. Meaning it's unmodified and probably wasn't meant for AOSP. Could that be the issue some code in the modern not working with aosp [MENTION=4852479]houstonn[/MENTION] . I was just noticing the rooms without issues seem to use their own modded versions of the modem.

Also I'm personally not having the issue just trying to help

I now have this issue im on sprint g2 and exactly what bps119 said is what happend to me on carbon rom after the kk source update.
[G2 General] willbs94:
What I don't understand is that the issue was stated somewhere that it has to do with what type of screen you had. Jdi or lgd. This makes sense to me. If the kernel is made for lgd then it will work fine for the devices that have that type of screen. In my case, I have the D800 that uses a lgd. I was seeing that the D802(in some cases has the jdi) as well as the Verizon/Sprint models. I'm not fully sure if this is correct.

I want to know that if the people with the borked screens have the jdi panel. I'll post the link with credit for the app when I find it.

[G2 General] willbs94:
Well the panel isn't it. I'm really annoyed as to wtf is happening. I think it may be the power issue. Maybe at some point in boot after flashing. Too much power or not enough. I have no idea. Only time I have seen actual lines like shown are from overheated GPU or dropped phones. Seen it plenty of times on computer LCD. Well I hope someone figures it out.
[G2 General] WolfmanJack:
Has anyone thought to pull a screen from one of these phones running a black lined screen and swap it into a stock G2? That would tell you instantly whether or not this is a permanent problem or not. I understand some people are going to say that flashing back to stock solves this without the screen swap but lets think about that. I had issues arise that were solved by simply re flashing. Took the same steps, using the same file with the same sums and the issue disappears... Some stuff dirty flashes without a hiccup other stuff doesn't. To me then relying on that as a basis is still got a little to many variables in it for me.
