My G4 screen is transparent? - G4 Q&A, Help & Troubleshooting

Hey there..
So I'm an owner of the G4 for less than a year.. I had a problem with him which was that he got into a boot loop.. I've sent him to get fixed but he came back with another problem... When I scroll down the task manager or open apps with dark theme, my screen shows pinkish parts and transparent icons.. Can any of you help me to fix it?

Your screen is having an image retention issue. Its HW related and goes away only by changing the whole LCD unit.

Yes. Its HW failure. You can google lg g4 screen retention and you're not the only one.
My phone just came from service and they changed the whole display unit and frame.

Oh ok.. And I have another problem since my phone came back from the lab.. The phone charges really really really slow.. Before it used to charge from 0 to 100 in 1 and a half hours when I dont touch it.. Now it takes from 20 to 100 like 3-4 hours.. Untouched.. I dont touch the phone while it charges... So what should I do with it? send it to get fixed..? again? I'm really frustirated.. I bought this phone like 8-10 months ago.. and since the first day I'm having problems with it.. Really disapointed..

Check with os monitor or something similar that is your logd keeping your phone awake (preventing deep sleep mode).
And check your charger as well.

please help. white screen problem!

hey all i am currently having a problem with me htc s621.
when my phone is on it randomly turns to a white screen after a 2 day period or so. and after a while of turning off phone/taking out battery/taking out sim card and doing this a lot it goes back to normal. im getting pretty mad and was wondering if i need to get my phone replaced or what.
any advice is helpfull. and the phone is not updated to 6.1 or anything like that. btw it all started to happen after i dropped my phone one time. i am not sure if that helps or not.
thanks in advance

The phone may be damaged. Is it a stock phone or has it be flashed with a rom?
it is purely stock no upgrades at all. today it did something new, it was white then 20 min later wen back to normal without me turning it off or anything. should i bring it in into warintee or anything i can do to help it?
I have seen simular situations before. It is possible that when you dropped it, the ribbon cable connecting the LCD to the board became dislodged and is only making a partial connection. Or the LCD is just plain broken and needs to be replaced. You can get a new LCD on ebay for around $30 USD and do it yourself or take it to a repair shop and have then look at it for you.
i believe i will take it into the store tommorow. get a professional statement and opinion to see what i should do. thanks alot guys

I recall reading some time back concering the cause of the white screen had something to do with the backlight time, try making some adjustments with the backlight. Also do a serious search for that old thread dealing with this problem..............!
You would probably need a new screen and the best option would be to replace it yourself because you could find a cheap one off ebay and then just youtube and you could find on how to install the new screen.

[Q] Screen problems

My screen randomly freezes, with Android still running in the background. It also has multicolored "snow" static-like crap on the screen instead of an image half of the time, especially when unlocking the screen. Happens when the kernel hasn't even finished booting as well. I also get visual artifacts appearing on screen, which would be expected if my GPU was OC'd, but it's not. Tried stock, didn't help, so I know it's a hardware problem.
I suspect it might be the slider ribbon, or the screen itself, but I want to know what it most likely is before trying to order parts and spending the money. If it's being caused by the GPU, I'm just gonna pick up a new part-time job and buy a new phone altogether..
Any ideas?
Same problem, same suspicions. I'm taking mine apart and will advise.
Got it back together... no change. Might just be the GPU.
Sometimes while the screen is glitching, moving the slider gets it to work. I'm thinking the ribbon cable in the slider might be damaged on the inside.
I'm gonna try replacing it since the part is $11 on Ebay.

It's not the kernel. I've tried every gsm kernel available, wiped the boot partition with fastboot, wiped everything, installed stock. Doesn't make any difference. 100% a hardware problem.

I'm wondering if the actual flex cable itself. Since I just derped and sat on my phone and broke the digitizer, I'm just gonna get the whole screen assembly (Since it's only about 5$ cheaper). It could be a while though. I can't order it till next tuesday.
I used to have similar problems on my g2 until I replaced the flex cable. But then again, the image seems to freeze and occasionally glitch, so I'm wondering if there's a faulty solder connection somewhere since shaking/beating/banging on the phone seems to also fix it sometimes.
I managed to dig up four old threads where multiple people had the exact same problems as me, replaced the flex cable, then had zero issues afterwards.
I was just reading them an hour ago. 100% sure the cable is the problem for my phone.
Now it's just a waiting game, first waiting until I have some cash, then waiting for the e-cheque to clear, then the shipment.. I'm gonna have to wait at least a month unless somebody goes and ships one to my door instantly.. Which obviously ain't gonna happen as I'm not a developer and just someone who helps ppl with their phones.
I'm gonna save up and buy a new phone, then give this one to my 11 year old niece after it's repaired. By the time I have enough cash for one of those new HTC models, the cable should be here.

Well if you do it before me, please let me know!! And I'll be sure to report back! I'll order the screen assembly next tuesday.

Sorry to resurrect this...
Sorry to resurrect this out of the blue, but I am also having a similar problem.
I have not rooted my R800at, but noticed first that the screen would sometimes stretch or skew into an absurdly distorted shape, only to snap back to normal after unlocking the screen.
Then, a few days ago, I also started to get this colorized snow pattern on my screen. I was wondering if you managed to fix your phone by ordering the cable? Also, not to sound too much like a pathetic n00b, is there a .doc somewhere (Or PDF) showing how to disassemble the phone to replace the cable, if that indeed fixed the problem?
I am going to see if AT&T will warranty the phone (Less than a year old, more than 30 days, not more than 90) but I am unsure if it is going to cost me an arm and a leg to do so.

The phone comes with a one-year manufacturer warranty. Since you aren't rooted or unlocked, send it in for repair. If you open up the phone to fix the cable yourself you'll end voiding the warranty permanently. If something else breaks later down the road that's harder to fix, you're gonna need it.

hey everyone well after reach tru this thread i think my flex cable is the problem as well
a while back when i unlock the fone the screen just use to be all jumpy (but i dont think dat was related to the flec cable problem cuz after changing wallpaper it stopped)
but like ah few weeks after i changed my rom, if i didn't slide out my gampad my phone wouldn't unlock, sometimes when i turn it off(the phone vibrates as usual but the screen nevr comes on) and then now like its completely gone i'm getting nothing from the screen anymore
so i'm guessing its the flex cable
and i think thats the reason for my front camera to stop wrking as well
FIX!

[Q] Screen flickering (CRT like)

Hi,
EDIT
Resolved it (kinda), I shut the "Economy mode" and the screen stop the flickering....
---
I'm creating a new thread for this problem got an answer there telling me it's my phone, but I would like to know if somebody else notice this.
It's like on good old CRT. Got a Note I (got stolen) bought a Note 2 and I can see a flickering, like if the display had a 60Hz refresh rate, never notice such a thing with the Note I.
It's more noticeable on white screens. And when you are using peripheral vision, by pointing your eyes like 10 centimeters from the side of the device, the flickering must be more visible
The effect looks like this http://www.youtube.com/watch?v=M3jHOwE8MqA not mine but can give an idea of the problem.
Thanks

Never notice it with my Note I, it seems that it's partly due to AMOLED technology, but as I did not notice it on my Note I...
Maybe it varies form device to device...

Don't feed the troll
Ok, so if you do not own this device the Note 2, and do not want the device, why chime in and post/comments...
My scraan is flickering too. Feels like old CRT TV. When brightness not at 100% level I can observe this problem. Looks like samsung using PWM to control brightness. I think this is terrible. And I hope this can be fixed by software (adjust brightness by gamma correction etc)
mine also sometimes flickering on the lock screen in the near clock area for about 0,5-1 sec. but no need to worry, i guess its a hidden samsung note 2 feature...
So there are no solutions to fix screen flickering? Maybe we can overclock screen somehow? Maybe alternative brightness control?
The screen flicker mus be due to a bad batch of screens. Mine had the screen flickering too. and even with economy mode shut down and brightness is set to less then 100%. if you rapidly move the phone you can see that you see several screens instead of a blurry moving screen. this way you know it flickers. so for example if you move your phone up and down very rapidly instead of seeing a blurry view of the screen you will see several edges of the screen simultaniously. this tells you its flickering. While just looking at the screen you wont actually see the flickering but its somehow disturbing.
The way i know that your screen is defect is because due to a rescent replacement of my screen on my note 2 the flickering is totally gone now.
But keep in mind that my battery usages with screen on has increased. so i think samsung changed the power management for these new screens so that they wont flicker anymore. but they consume more power now. first i used the screen 6,5 hours and had a standby of 24 hours. now i have 6 hours screen on time with 24 hours standby. so its a bit of a change though. I just tested it 1 time. so it could also be i used the phone in another way when getting only 6 hours.
But just to let you guys know the flickering can be fixed.

Green hue on all blacks appeared?

The screen on my note 3 suddenly showed a green hue color. I took some screen shots to show but after I pressed the power button(standby) to turn screen off then back on again the green hue disappeared?
So thinking the pictures would still prove the issue, no I was wrong the screen captures I took with the green hue are also fine . Not sure whats going on...Perhaps it is hardware related hence why it does not show in the captures. Basically all the blacks had a green hue to them / in fact were green .
Today is the 14th day for me to return or exchange the device at t mobile. Please advise. I did install some dark wallpaper apps but deleted them yesterday, was using normal stock wallpapers. I am not rooted.
Do you think it is hardware related? I believe if it was software related then the screen captures ( which I took when screen went green) would also show the green hue.
Had the same problem here but mine had a pink hue.Try to reset the colors. Just type *#0*# on your phone dialer and use the 3 colors for 5 minutes each, it will reset the pixels.

It went away when I pressed it on standby and back again.
What gets me concerned is that when I took a screen shot when it was green it didn't show on the picture after it remedied itself.

So have the problem gotten worse since then?
I have seen it now and then. Often happened when I was on the phone and closed and opened the lid.
Happened now that I opened the lid after attaching it to the charger.
Should I expect it to get worse, and therefore return it for a new one or will it be a rare bug now and then?
Reading mode enabled?

Hi,
I bought mine in October 4th 2013, has occurred twice so far. Taking screen shots does not show it. I am thinking it is a software glitch.

If you are doing a screen shot, it is reading the state from the device and saving it. So later if you look at that screen shot and it looks okay it most likely is not software. If you look at the screen shot while the unit is displaying the green look and it looks right, then you most likely have a software issue.
Sounds like a hardware issue or perhaps some weird mode being set by software. I still think it is hardware though.

I perhaps hoped that you had answered my question when I first posted as this occurrence first happened on the 14th day of my purchase, so I had a choice to return to T Mobile store for swap out. Either way, only occurred twice so far, so I am not worrying too much about it. Shelf life for phone for me is approx 12 months max, so all is good thus far. Pressing the standby button afaik cleared it up at the times it occured.
I too have had this happen twice now and months in between. Happened after mj5 update could that be a cause

Doubt it, as mine is stock N900T that has no updates as of yet.
The first time I rebooted and it went away. The second time it was only like that for a few seconds and cleared up on its own. I'm on the at&t version

Mines does this once every few days apart, if I just turn off the screen and turn it back on it goes away. I also took screen shoots but they show fine in the gallery. I only seen it once on my wife's note.
I have exactly the same problem, the green hue appear, and turning off the screen or dial *#0*# and select one of the color to test the screen can clear that away. it happens once per one or two weeks for me. I'm worried that may be a hardware issues and that is a symptom before the device fail. Does any of you have this happened then your phone became not working ?
btw, It's seems happens after I changed to a magnetic flip case ,not sure if that's related, will try not using that case and see if that will gone away. Are you guys having this problem also using a case with magnetic flip ?

That burn in is really bad. It's got to be a problem with your screen, and not common to all G4s or we'd be seeing others complaining by now.
I've seen phones that bad in stores, but their screens are on all the time. How much screen time have you had with Opera running?
Good thing the provider is replacing it!

hmm not that long troug. if i use opera a while not it disappears almost completely.
use it agian 2 minutes. its bck
and restarting my phone does not help.
removing opera does also not help.
if i got my new phone no opera anymore.
I just can't believe that's from Opera alone. There had to be a problem with the LCD in your phone.
I understand if you don't want to risk it by using Opera anymore but I don't think it'll happen with your new phone.

Lcd on mobile phones normally never get burnins, it's an amoled thingy (samsung phones) and it's an important reason I wont get a note 4 but a G4, so I really hope it was a single defective screen.
Did you try one of the screen retention fix app?
Did you try a factory reset? Call me crazy but it's not normal that a screen burnin doesn't affect white pixels, and it shouldn't do a green stuff, it could be a crazy bug

That's not "backlight leak" or "light bleed" as it's generally called. It's a bad LCD panel.
FYI This is how light bleed on the G4 can look like (It's mine).
I have a new device. So it's solved. But I see more people getting problems with the screen.
That's more likely to be just image retention and not an actual burn in.
Burn in = actual damage since the material gets burnt out than the rest of the other materials in the screen.
Image Retention = the liquid crystals on the LCD haven't fully returned to their original state for the meantime only.
A burn in commonly happens on crt, plasma, oled screens. For the reason that these technologies "burn" a specific material on their screen to produce output. LCD screens like IPS are very less likely to have burn ins but image retention is always possible but not permanent.

So is image retention common, because I've never had this problem until I got the G4 which is my first flagship: every other phone I've had was a budget and never had a problem like this.
I've never had image retention or burn in on any of my LCD phones but have had it on all my OLED/AMOLED phones.

LG used this "Quantum Display" of theirs (A modified type of IPS LCD) which had a different arrangement of pixels and whatnots which would have likely been the reason why image retention was much more common on theirs than other manufacturers' IPS displays, but in return.. the color gamut of their display actually expanded in range and also provided less energy consumption.
Same here LG G4 "screen burnes" all the time!!! - previous screens stay faded over current screens, just like on my old plasma TV... WTF???
I don't know what is screenburn but sometimes I see vertical narrow black stripes popping for a second in the same place, any thoughts what this can be? Is that a faulty display or some software bug, anyone had this issue?
What did other people who had this issue?
Now I'm also having it. Own the phone since ~11month. I recognized it 2 weeks ago, researching the problem. Before I though it would be a graphic error.
Have the plan to write LG about my issue. But have rooted the phone the official way. I must lookt at the LG root condition, I think this is still covered by waranty even with root because of HW issue not caused by root.
BR
I had a image retention issues on my screen (few months ago came from service for bootlooping) AND I have bootloader officially unlocked. And they still changed my display. But I live in Finland EU and we have this mandatory 2 years warranty regardless of rooting the device. Only if they can proof that rooting caused the device to broke then its not covered by this mandatory manufacturer independant warranty.
But image retention or bootlooping aint such a case and they replaced my MB and now my screen.
It just shows how **** the G4 is in case of build quality, I have experienced screenburn and I'm after a bootloop issue as well, so glad my OnePlus 3 is coming at Monday. G4 has a great development and thats why I love it I wouldn't buy ever again.
