You mean the yellow tint on the bottom part of the display? Yeah, that's because the phone ships to you in less than a week after it's been manufactured. Look it up on Google. Letting it dry or using a UV light on it for a few minutes does the trick.

If you are talking about the chance of getting an unit which has a LCD display that got parts where the whites are yellowish... Yeah, my girlfriend just got her Galaxy S4 Mini's display replaced today and guess what, it's yellow-tinted in the top side. SO IS MY (second) G2 - although it's bareable, I'll probably take it in for repair later down the road.

I thought LCD is perfect. Looks like it can be just as crappy as AMOLED :)
[G2 General] biert87:
So I returned my g2 with black lines to the Telekom shop next to me on Saturday, yesterday I got a "like new" unit as a replacement. Flashed it right away and works fine for now
[G2 General] Formhault:
Of course it works fine :silly:.

Glad you got a replacement.
[G2 General] DerDave:
So I have read through the last five pages and it was mainly "me-too" posts and discussion about wether or not it is normal for phones to have broken hardware.

I'd to know, if any ROM maintainers are working on the problem or if there are already some solutions ideas how to get around the problem.

Thanks in advance!
[G2 General] Formhault:
You certainly didn't read enough. At least not up to the parts where we talked about heat being the main culprit and how that can be avoided by using dr87's TWRP mod (which has thermal throttling) and a good kernel (which also has thermal throttling), so that the CPU doesn't go spewing in flames damaging all the components around it (and the screen / connectors, implicitly).

So, long story short : use dr87's TWRP mod and flash a custom ROM and a good kernel (Render Kernel or Vanir's DorimanX Port for AOSP ROMs || DorimanX for LG ROMs). That should keep you safe.

But... keep in mind... we don't know for sure if the heat is what causes this issue. Or to what extent. For all we know, it could be a little heat for some devices, and very much heat for other devices... or no heat at all for some (there's been reports from people who didn't really got their G2's too hot).
[G2 General] DerDave:
Thanks very much for this helpful answer. Sorry I didn't read back long enough.

I'm just getting a little worried because my G2 gets extremely hot, especially while surfing with chrome and charging at the same time (what I'm not doing anymore). But even without charging it doesn't feel healthy.

I'm running the latest official Omni nightlies. The maintainer is just porting the 4.4 sources and also putting a lot of effort in the heat problem.

I just wanted to see if other ROM maintainers are also working on that.
[G2 General] Formhault:
Mine gets hot when it's charging up and I'm using it at the same time, too. But not every time. Looks like there's some sort of... thing that kicks in SOME TIMES so that the phone doesn't charge up very fast while it's being used; but other times, damn, it's fast charging off of the charger while I'm using it and it gets so hot... Not sure what that's all about.

Anyway, the CPU starts to throttle down on the frequency when the temperature reaches 80 Celsius. When it reaches 80 Celsius, you'll feel it on your fingers... and if it exceeds that, you can stop worrying about your phone and start worrying about touching the top side of the glass :silly:.

Well, your best bet is to ask in the ROM(s) thread(s) and see if there's thermal throttling implemented. If it's not in the ROM, it sure is in the kernel. If it's in both, it's even better. Mahdi ROM has that for sure - because dr87 (the maintainer of Mahdi ROM for the G2) is very aware of this... screen issue.
[G2 General] DerDave:
I assume in the Stock ROMs fast charging stopps and gets replaced by "normal charging" when the phone is in use to prevent said overheating. If my theory is right, Omni definitely doesn't behave like that, because it ALWAYS gets hot when charging and using it at the same time.

Yes the heat throttles the CPU. In my case sometimes so much, that opening a keyboard app takes up to 5 seconds and every scrolling stutters like hell.

Unfortunately I can't post in the ROM threads, because I don't have enough posts, which automatically means, that I'm a spamming noob, who obviously has no idea what he's talking about. :p

Anyway thanks for your help and for the hint with Mahdi ROM. I will give that a shot, before my screen burns out.
[G2 General] Formhault:
Well, I've tried custom ROMs (and kernels) that were mostly stock, and the behavior was the same. During gameplay, I plug in the charger, and 5 minutes later I realize it's charging very fast. I repeat the procedure some time later, and it's charging slower. So it's really random, I guess.... bugged firmware... I dunno...

If you've got warranty, relax. Scorch your phone as much as you want :silly:
[G2 General] GoJo ^^:
Is it possible to damage an LCD with software code, LCD being turned off..?

Actually I received somekind of blackmail about this and since I really don't believe I caused damage, I'm am starting to wonder..
[G2 General] dadme:
Maybe it's a good idea to do downgrade to version 4.2.2. Less heat means less likely to damage anything, filters the motherboard. My son suffers phone screen, but oscillatory phenomenon occurs after 2-3 minutes out of standby, so chances are to be produced by temperature too high. 4.2.2 require less CPU obviously, and times were better battery. The only problem that remains at downgrade that double tap won't work becouse touch firmware is already upgraded.
[G2 General] Formhault:
I doubt it is software related :)
[G2 General] abs2k:
it's possible to suffer other black lines after the first ones? i have the problem in my g2 and i don't have warranty.... and the replacement comes in 1 month... damn. sorry for my poor english. i have just one black line. and i don't want more.

:crying:
[G2 General] GoJo ^^:
Regarding my issue, i found this page : http://phonedoctors.com/i-changed-my-iphone-screen-and-now-i-see-something-like-this/ this part "A white halo around your screen: This is caused by a flaw in the soldering of the initial screen. These are difficult to pickup prior to installation as the halo normally shows up a few days after use"
[G2 General] Formhault:
People have reported that they had X ammount of lines, and when they pressed down on the bottom part of the LCD (where the LG logo is), more lines showed up, temporarily. Also, some claimed they had more (temporary) lines during gameplay (intense heat).

I'd say wait for the entire screen to go bonkers and THEN pay for a new display unit. Unless that one line is bothering you so much / you got plenty of cash :D. I mean one line isn't so bad...

---------- Post added at 10:32 AM ---------- Previous post was at 10:28 AM ----------

I guess that is it, then. It's strange, though, how the halo (it looked more like light bleed, but not quite) didn't seem to be permanent.

I had this white halo issue on my previous G2 - which I sold. I now have another G2 which doesn't have the white halo issue. But my previous G2... some times, I would even get it out of my pocket (not having used it for a while) and the halo would be very obvious. Other times, I would game on it for hours, and the halo wouldn't show up.

I noticed it was more likely to show up when the phone was charging. Even so... for two days in a row, when I wanted to show it to other people, it DIDN'T show up (while charging). :eek: :eek:

Luckily, my new G2 doesn't have it. It does, however, have inconsistent color reproduction (whites) across the display, so I will still have to take it in for warranty. Hope not any time soon though...
[G2 General] abs2k:
Thanks! I wait :cool:
[G2 General] GoJo ^^:
In fact first I have a halo, then it expend rapidly, after a while black turns to Grey..

[G2 General] GoJo ^^:
Sorry bu that's too late. Now when i turn screen on, it takes seconds before the **** starts and it's HUGE compared to before. Looks like it's dying for real now. Notice that i didn't drop it a single time since issue started. So it takes quite long for things to start truly showing..
[G2 General] reaper61616:
Today I'll send my D802 to LGE Center for warranty repair. Will see what happend.

Hope they will fix my phone. ;)

BTW. What they will do? Change LCD? Change board? Replace unit? Or sent me back phone with problem and tell warranty is void? Someone with this issue sent G2 for repair?

I go back to stock yesterday. Hope they will not figure out what was happend with device.:D
[G2 General] Formhault:
Regardless... video record the issue so the world can see how much LG has f***ed up :).

---------- Post added at 10:10 AM ---------- Previous post was at 10:06 AM ----------

Many have brought their G2's in for screen-related repairs. LG didn't turn their back on them. They'll fix your phone ;) probably by replacing the screen or whatever it is that was causing the issue you were having (not sure what that is, by the way).
[G2 General] reaper61616:
I recive mail from LGE service center today...

THEY WILL REPAIR MY DEVICE. :laugh::laugh::laugh:
[G2 General] Formhault:
Of course they will. I didn't doubt at any moment :p

Anyway, glad that you're happy :good:
[G2 General] NxtGenCowboy:
I just had my G2 replaced again. Rebooted cause it locked up and the lines appeared. It def happens during the boot process. When the screen goes crazy for a few seconds. Happened both times on CarbonRom which shouldn't really matter but who knows. It seems to be happening so random. VZW/LG knows it is an issue...When I was on the phone they kept stating they would just keep replacing it til they can't anymore.
[G2 General] Formhault:
Locked up? What do you mean? Froze?

Of course. They have plenty units in stock, lol.

You could file a complaint at the Customer Protection (if you have such an organization there). Show them how many replacements you got => model line clearly f***ed up => you want your money back. Of course... after more than 3 replacements.
[G2 General] divine1250:
Ok. I have had this phone and had zero problems flash any rom until i flashed aosp. flashed optimus g3 rom and cloudy g3 rom with zero problems. I got sort of lucky because the lines i have are nothing like what i have seen on this thread. i can even hide them by using dark wallpaper. My phone was never too hot to cause over-heat damage!!! All i did was flash AICP 5.0 KK 4.4.4 r2!!!! As soon as the phone booted the screen weirdness started. I got scared but let it boot completely until i was taken to set up(No lines yet). After set up i reboot phone and was greeted with a few lines on the right hand side. So rebooted to recovery and flashed my stock back up and still had lines but knock on didnt work anymore(Getting Scared Now).went back to recovery and flashed cloudy g3 rom and still had lines but knock on now works again.So im staying on cloudy g3 until someone figures this out.doesnt sound hardware related to me. Any thoughts?
[G2 General] drivenby:
Were the lines present in recovery?
[G2 General] divine1250:
yes

I'm sorry to tell you but I'm almost 99% sure it's hardware :/

There is no fix, because the damage is done at the hardware level.

You can alleviate the problem with the app mentioned before (I can't remember its name right now) or using a specific wallpaper.

The definitive fix is to replace the screen panel. No software can repair our damaged screens, unfortunately.

Don't know if it's been mentioned yet but there are screen replacements selling on eBay for less than $50 now. If you have no warranty that is less than the deductible on most insurance plans and not very hard to do your self.
[G2 General] mdeevee:
Well that's exactly the choice I have to make... insurance claim or self fix. Think I'll go the insurance route because I'm sure I'll screw up any self fix! I'm almost oblivious to the lines at this point.

Hello everybody here, let me explain my very weird screen issue. First I have an LG G2 D800 from AT&T Unlocked I bought it at Amazon on December. This began like a month ago. I was using my device normally and it freezes the screen, for example if i was playing music It freezes like a screenshot but if a pressed any button i could change the next song. This was getting more often but now my phone doesn't turn on the screen. i try to power off it shows me the LG logo after bootanimation. But Screen does not response it tries to wake up but it can i see hoe the black screen get illuminated but it only shows black. I flashed the stock 4.2.2 with download mode.
[G2 General] Compass Linux:
It seems like a hardware problem (I think I've seen screenshots in this very same thread just like yours), but can you tell us a few things first:

1. Which version of android are you using?

2. Is it rooted?

3. Do you have custom recovery? If so, which one?

4. Are you using a Custom/AOSP/etc ROM?

5. Can you get into the stock recovery (if that's what you have) or download mode?

Compass.
[G2 General] 1ceb0x:
One thing that you can do to make this issue to not appear for you - do not reboot when your phone is very hot.

I have used a ROM with broken thermal protection (i won't give the name - it is fixed now anyway) and used my phone in Saturday morning (browsing etc), phone got hot, rebooted itself, in LG logo the screen started to turn in weird ass colors, the LG logo disappeared then it rebooted itself with 15-20 black lines on the right side.

I will be at my second panel change and it seems that the guy from the service is already tired - this makes me think that a lot of people went back with their phones. Also, the stock was empty but he mentioned that they already ordered them back a few weeks ago (which also makes my hypothesis more credible).

Anyway - good thing is, it is not something AOSP related, or custom roms. It is just the poor design of the phone. What to expect when they cramped together a big battery + thin bezels. The heat has nowhere to go, thus the damages are most likely to happen when your phone is hot. Be also careful with rogue apps that are keeping your phone hot for big period of times.

Cheers!
[G2 General] JABS_2109:
Hi Compass,! yeah I posted it, but i need an answer hehe. Well I had optimusG3 rom port since 1.0 and then I upgraded it to 1.3.1. My screen was freezing itself but like a screenshot by example if i was in music player it freezes there, but if if pressed HOME it went there but, with the music screen freeze.

It was rooted I dont remember which recovery i had. If i get download mode is with the LG LOGO.

It's very weird, dont you think?

Last I did, was flashing 4.2.2 stock att rom with TOT file, I mean with LG Flashtool.

But if it is not screen and is not software, what else could be?

I didnt drop it.
[G2 General] Compass Linux:
If you went back to stock by flashing a TOT and the problem persists, I'd say you have a serious hardware issue. If you're still under warranty, go back to stock TOT and send it in. If not under warranty, see how much it will cost to fix.

The problem is either software or hardware related, nothing else.You can't go back to stock more than flashing a TOT, and since that didn't fix, it's probably a hardware problem.

Unroot/return to stock for return to Asurion?

Does anyone think it matters when it's an insurance replacement? The last time I had to unroot and return to stock seemed like a real PIA. Thanks for any advice.
[G2 General] Formhault:
I don't really know, but since this is an insurance we are talking about, it shouldn't matter, I guess. I mean you are paying for the insurance, so...

Go back to stock, though. Just to be on the safe side...

my screen started showing this burnt yellowish tint...can anybody tell me what it is? Is there a solution or do i have to change the lcd? It does not interfere with any dark colour and shows up only on the lighter colour? I hope you understand what i m trying to say..
[G2 General] breakfastdude:
I seem to have some kind of halo effect on my screen, it's like there's this bright 1cm-wide strip that kinda follows the borders of the screen, and it tapers off to normal colors towards the center of the screen. It's especially prominent on colors that aren't too bright or too dark (facebook loading screen when it first starts, for example). And it's super noticeable on CWM. Can't really picture it right now, as it comes and goes (I guess it is indeed kinda related to the phone's temperature). Thoughts? Is this a sign that my LCD's degrading, too?

EDIT: attached a link to the image
[G2 General] Formhault:
Upload image to dump.no please.

---------- Post added at 08:06 AM ---------- Previous post was at 08:03 AM ----------

Same here :)

The top half of the screen displays a yellowish white, while the bottom part displays a blueish white (in comparison). Most noticeable on white backgrounds.

Can't be fixed... Unless the LCD is replaced.
[G2 General] breakfastdude:
Oops, that didn't work. My bad. Here's the updated image link.
[G2 General] Formhault:
[/QUOTE]

Oh yeah ! My previous (first - sold after 3 weeks) G2 had that. This one (second) doesn't have those... borders. They're more noticeable on darker gray backgrounds. Such as... Battery Monitor Widget / STweaks / anything that has that AOSP gray gradient... or, if you open a white page and pull down the notification bar :silly:.

It drove me nuts. Which is why I got rid of that device and got another one, with warranty. Albeit... 16GB :(

Seek warranty replacement. I dunno what else to say... there's nothing else you can do about it.
[G2 General] nedooo:
After I saw this, I will avoid G2. I'm sorry for all folks that had (having) this issue.

LG manufactures top ips panels for others, but uses crappy for it's own devices. Strange?!?!

[MENTION=4129455]Formhault[/MENTION] I think that I am going to get the nexus5 because of this issue also... Yes I know I still didn't decided :rolleyes:
[G2 General] Formhault:
Lel... By the time you'll buy the N5, it would not be worth buying anymore :silly:
[G2 General] 1ceb0x:
I am thinking to do the same but G2 is overall the better device imo. And N5 has its own screen issues though not as bad as these ones... Search their threads and you'll see a lot of people complaining about dead pixels, yellow tints, touch screen failures etc..
[G2 General] wulsic:
Lol that's true :silly: Its just a though decision for me since I want a good phone which will last for an long time but by the time I would made the decision the phone would probably dropped like 20 euro :eek:

I mean like the nexus 5 also got problems that's true but not things like vertical lines on the display even if it's rare. and with 1 crack on the digitizer/glass on the G2 can stopresponding
[G2 General] 1ceb0x:
wait for n6. not too much left to go :)
[G2 General] wulsic:
Yeah I want to wait but that's too expensive for meh :silly: I just have enough for the g2/N5
[G2 General] Formhault:
How much is a 32GB G2 there? With warranty and all that...

If it's under 350 EUR, get it already. You can't possibly expect to buy a BMW at the price of a Renault.
[G2 General] 1ceb0x:
Should not be that expensive IMO. A few extra bucks on top of G2 and you should be able to cover an N6.
[G2 General] Formhault:
Lel

This ain't the US. It will cost a **** load anywhere else except there.
[G2 General] 1ceb0x:
it will not cost same as a g2 of 32 gb. it will be less than that. so yeah, from my position now, if i sell my g2, i will be able to buy an n6 with a bit of effort.
[G2 General] Formhault:
So... Less than 400 EUR? You sure about that?

It will probably be 349 EUR in Europe, like it has always been. Because, you know, $349 = 349 EUR... 1 EUR isn't even 1.6 USD. No. They know better. ****ing bastards.

But... Even so, that price would be for the Play Store enabled countries. Which exclude my country (and probably [MENTION=5403922]wulsic[/MENTION]'s, too). So, 500 freaking EUR it is :).
[G2 General] wulsic:
[MENTION=4129455]Formhault[/MENTION] yes Playstore is being an douche like 400$ there Europe 400 Euro, when I saw that I also thought wth that can't be right. I don't have a job since I am still 14 and it's not worth it to work if you see that there are only Hour jobs with small anmount of pocket money you earn and the government will also remove that from the money you get so it's useless then.

I only have a max of 250 euro although I want to pay 200 Euro only ;/ So I can only choose between Nexus5 16GB and LG G2 16GB.
[G2 General] 1ceb0x:
go for the new moto x at that budget. sell g2 and buy moto x.
[G2 General] wulsic:
Thanks for theTip but that won't be possible :silly: Here in the netherlands it will go on sale in october for 549 euro

I thought you're ~20 :p. You know, back when I was your age, I was happy to rock the Motorola V360 with a Monster Pack on it :D. Anyway... times have changed.

I'd say get the G2. The N5 is not worth it, especially if it is priced similarly to the G2... I mean I have the 16GB variant and it's fine. I can plug in one of the two microSD cards I got laying around via a USB OTG cable and use them whenever I feel like watching a >2GB movie or something. At least I'm covered by warranty for 20 more months :D.

Can you afford to get a 16GB G2 with warranty right now?

Yes, the OTG function is pretty awesome.

Keyboard works, mouse works, USB drives work. It works best with the OTG USB powered cable though, so you don't drain the phones battery (when possible).
