LCD dark patches - LG Optimus Black

When my phone battery gets low on my OB I start to get random dark patches up my screen if I'm on full brightness and using the phone for long periods of time. It's almost like some LED's start to power off in the LCD. This can be fixed with a quick lock/sleep then unlock/wake of my phone. Does anyone else have this problem?

Lol think you burned off some of your LCDs.But seriously i think you should send it to LG service centre cause its probably a hardwarevproblem.All the best!
My main agenda is to help, not gain thanks.

does it do that when charging?
have you modified your voltage?

Nope, it's still on the original LG GB rom, I'm going to wait until ICS comes out (if it ever does) to see how good it is before I install custom roms on my OB. I dropped my OB from a very short height one day (out of my pocket while I was standing up from sitting on the ground) and it bounced off the concrete, it now has a small dent in the plastic on one of the sides, do you think the service center will care about this cause I don't want to be charged $55 just for them to send it back and not do anything about the problem.

I dont think so...if you dont want to pay, you can ask them to see what they can do and if it costs something ask them to notify you
If the one working takes your warranty card/paper without saying anything it means you dont have to pay

LCD Displays generally have this behaviour if one uses the same images for hours together, But i have never experienced this with my phone, Try using phone @ 40% brightness which is more than enough at all times, It will save ur battery consumption as well.

Screenshot or it didn't happen!!
Lol
But i never heard about this before.
Might have something to do with the auto brightness setting. Does this also happen when you set the brightness manually?

It doesn't show up in screenshots but here is a photo of the phone with the dark patch, it's very obvious when you look at it in real life just doesn't show up in pictures too well.

The screenshot thing wasn't serious tho, hardware trouble can't be captured that way .
But this is definitely not software related.
Maybe unplugging and reconnecting the display connector helps, if not this is probably a fault in how the phone controls your display. You'll probably have this problem with every rom you try. If that's the case, put a stock rom on it and get it repaired.
It hasn't anything to do with having the same image on for a long time because the dark spots appear random on your screen. Might be a backlight problem.

A possible problem

Hello guys I never noticed it but for some time I noticed something strange on the screen of my galaxy S. Putting it in landscape in the upper left corner i see the notification bar as if it's printed on the screen. I don't post any screen because in these you can't see what you see on the screen phone and that's what worries me
Sorry for my english
Thanks

Screen burn in. Get launcherpro or a new launcher that can turn off notification bar

Yes but the problem persists. Is it a display problem then? How can i fix it?

Well since the picture is already burned in to your screen, the only way to fix it is to change the display. If you haven't opened the phone etc. then you can just take it to a service centre. I'm quite sure that burn in is covered under the warranty, so you won't have to pay anything.
You could first try to take the battery out for a couple of hours and see if it helps.
If that doesn't work, you can try to somehow put a bright white on the whole screen on the phone and keep it about an hour.
If none of those solutions work, just take it to a service centre.

Well yes, you've had the problem once so you could have it again. But warranties are there to ensure that you have a product that functions as expected. If Samsung are willing replace the item at no charge under warranty then it's obvious this is not the expected behaviour. Based on that logic not only is it your right to get a replacement, Samsung aren't really expecting it to happen again, otherwise burn in would be expected behaviour and not covered under warranty. Anyway my point, although so far, poorly made, is that it's not expected to happen again. Well that and so few other people have the same problem, it's extremely unlikely that it will happen again.

Exactly. Burn in is probably quite rare, especially in LED and LCD screens. I was actually surprised when I read your post. Old CRT screens used to get burn in quite often if one screen was left on for a long time. But since SGS has an AMOLED screen, the chances of a burn in happening again any time soon is quite slim.
You can try one of them burn in repair videos that just keep flashing colours that they use to unstuck pixels on lcd screens. You can get the video from youtube or anyplace you can and set media player to loop for a few hours. It might fix burn in.

Actually that wouldn't work, since the screen is AMOLED. There isn't any crystals that get stuck in one position. In LCD screens the pixels are tiny crystals that move in a way that a color is reflected to the screen. Sometimes these crystals get stuck in one position and so they show one color constantly. AMOLED screens have tiny LEDs that provide the colors to the screen. These can't get stuck, but they do wear out or burn out which leads to the colors not being produced correctly, and for that reason it'll look like a picture is stuck on the screen. That's something you probably can't do anything about.
Ok i'll see what to do.
Thanks to all!

Odd lock screen issue/glitch (white line across screen)

Just noticed an odd glitch on my Nexus7. When I press the lock screen button I notice a 1px heigh white line that varies in length, but normally about half the width of the screen and can be seen about half and inch up from the very button of the screen.. The line is visible approx 9 time out of 10 when locking the screen.
Has anybody else noticed this? I'm currently undecided if I should return due to a slight screen flicker in gmaps but if this is a real fault I guess this will help me make my mind up.
Does it show then go away with in a few of milliseconds? Mine does that very rarely
Sent from my Nexus 7 using xda premium
Yes that's it... To be honest I wouldn't normally see it as I rarely lock the screen manually, but I did this morning and noticed it. Think I may just leave it then.
I think I have a different issue from you guys and was wondering if you ever experienced this. Occasionally I get a vertical white line across the screen for a couple millisecond after I wake the device from sleep into the lockscreen.
I get the exact same thing on mine. I thought I was imagining it at first as it happens so fast. I would be interested to find out what it is.

Do you get a vertical white line or horizontal?
I'm glad I'm not the only one.. Mine is only horizontal and stays the exact distance up from the bottom of the screen each time. I'm guessing its not a major problem and I'm quite happy to live with it. Just hope I haven't stumbled upon another Nexus7 issue.

Restarts When Keyboard Closes Hard

Just got a droid 3 from Asurion to replace the D2G I cracked this weekend, and I don't want to sound like a whiner, but I'm not too impressed with it. Not liking the unlock button placement/it's hard to push (lawl), and the keyboard isn't as good (except for the number row that's nice), stock is kind of sluggish, and the screen seems kind of pixely and fuzzy in some places. But the biggest issue that I just found is that if i shut the keyboard at any speed slightly above average, the phone restarts completely. Does anyone else have this issue? Could it just be because it's most likely a refurb? Sorry for the complaints haha I'm just a bit disappointed but i'm sure the phone has its good qualities
Sometimes this happens to me as well, but not always. I think its the battery, when you shake the phone you can fell the battery moving + restart

If it is the battery what you can do is take a piece of scotch tape and roll it end to end and stick it between the battery door and battery. As far as the lag wait until CM9/10 is done.

At one point I tried a third party extended battery I found on Amazon and it caused this exact problem (and also restarts at other times). The fit of the battery was kind of loose and when shaken or handled just so, it would restart. Is it a refurbished phone? Refurb or not - check to see if it is a Motorola battery in it. If it is the battery being loose causing it, I'ed request another replacement. You shouldn't have to mess with a phone they just sent you to make it work.

thanks everyone, and yeah i think it's a refurb, sometime it shuts off randomly too. but it is strange because even if i shake the phone it doesn't shut off, only when i close the keyboard too quickly (which is any speed except slow and cautious), so i dont think its the battery being dislodged but who knows. it's def the right battery, but i think i might call asurion because i cant really deal with random power downs

[Q] Overheating?

I just got a replacement HTC One today (due to a power button issue). Within 5-10 minutes of use my One will hit about 110 degrees, sometimes up to 115. I use a task manager and I never had this problem with the first One I had. Any idea what could be causing this/what could prevent it?
If it didn't happen with the first phone, you should return that second phone.

So what was wrong with the first phone? The power button wasn't sitting flush? That's what happens when you return phones for stupid problems. So now you end up with a worst phone then before.

This.... which is why the tiny gap on the top I can live with.. Dont want to risk the chance of getting one with a dead pixel or something.
As for the over heating.. My phone gets a little warm but unless the blinking overheating led doesn't come up for no reason I wouldn't worry about it.

Mine too gets warm under stress use, like games and streaming video. I'm not measuring the temp because I don't care enough. I can feel it get warm is all.
Now that you mention it though, my volume buttons have been giving me a dirty look ever since I bought it... I think I'll return it. Screw HTC and their crap!! I'm getting an s4!!

The thing is, I paid for a phone in full working order. Regardless of if the defects are minor, they are still defects. I just want what I paid for.
Are we talking 115F? ...Or 115C.
Cause I'm inclined to believe its the former, and, if so, that's within a range I would consider normal.
If it's 115C, I'm surprised the phone is still on. Water would boil if put on the chip. The battery likely would have exploded by now.
Typically, you want to quote electronics temperatures in C.
115F isn't abnormal especially if you're pushing the CPU (heavy GPS or gaming), especially if you're referencing the battery temperature.
Generally you want to avoid anything above 50C, and that's not above 50C.
If it battery temp then it likely to be a bit high considering it sandwiched in between the LCD and the cpu board

Plus, I've decided that the all aluminum case helps dissapate heate from the board and therefore feels warmer than an equivalent plastic (read Galaxy S4 ) phone.

Nexus 4 screen issue ( Not a troubleshooting topic)

Hi everyone, i would like to share a experience i've had with both of my nexus 4 ordered from the google play with you other n4 possessors.
This is not a troubleshooting topic it's just a kind of survey i'm doing.
I've received my nexus 4 in december, and i noticed there was something going on with the display, some horizontal lines stayed on the screen while i was swiping the homescreen or changing image/scrolling webpages. Then after a while i noticed there was a dark horizontal line on the left side of the screen.This line doesn't appear on white images, it can be seen more on grey or dark backgrounds, e.g. put the 4th default wallpaper and scroll all the way to the left and you should be able to see it. Also, this line became more and more marked on the screen depending on the temperature of the battery, e.g. while charging or playing heavy games or flash player. I called google play ordered a replacement and i got it the day after, turn it on, install all my apps, and the line was STILL there, also on the new device.
My question is, am I so unlucky that i've received 2 faulted devices from google or everyone has this problem? can anyone please check?
P.s. put brightness to the maximum when checking.
where is this line appearing i cant understand

On the left of the screen, horizontal dark line, it can be seen better on a gray or dark image, such as the wallpaper i suggested
The line actually appears when I'm swiping away recent apps..hadn't noticed until now. It could probably be fixed with switching roms though. I'm on JD's perfect android right now. This is my 3rd nexus device, no problems on it, 303k.

Thanks for checking justin, can you also check it again when the battery gets warmer? like just play a heavy 3d game or charge the phone. it should be more marked, sometimes i can even see it over my power control widget :crying:
Yeah my line is different I believe, I put the phone to charge and put on grand theft auto. Nothing really appeared.

Are you sure you don't mean vertical line? on the left side.
If so then yes mine has it.
I can't see any line on my display
oh god guys i meant Vertical..meangreenie is right.. sorry everyone, i mean vertical line on the left of the screen!
I've got 2 vertical lines on both sides of the screen (left and right) and they're not that much visible but they're always there. IT just looks as if those sides were a little bit dimmer than the rest of the screen.
I have same problem on my n4,there's grey line on left screen which more visible when the device getting heat..is it possible to disappear by itself after few time?or should i claim my warranty?thx before and sorry for my bad english
Guys I'm having the same issue. Should I claim my warranty? Or any solution to make it disappear? For me this is a very costly phone and I don't wanna take any risks. I can see the line in most apps even in chrome while typing in address bar the window greys out. At that time its perfectly visible. Its jus 1 month old n now I'm **** scared

Guys please help
I'm glad I caught this thread. I bought a refurbished Nokia wireless charging plate. I didn't have the good sense to check XDA first, and sure enough the thing has compatibility issues. I thought I'd just leave it on the plate overnight to settle in as some people have suggested, and after about an hour my screen was violently flashing on and off with pronounced vertical lines over the screen (discoloration, not a line of pixels). After a while the lines mostly faded, but I can still see them just as described in this thread when I pull down the notification tray or open any app with a grey background (like the gallery).
I just got an RMA today. I'm wondering whether we've all experienced power issues or if I just didn't notice the lines until I was looking for them.

I'm not so sure that this is even a problem that an RMA is going to fix. Like I said, I only noticed it when I was looking for it. Might just be a charactaristic of a batch of panels, more like a light leak than damage.
However, if it is damage there is no way you're fixing it without an RMA. It's clearly not a software level issue.
I thought I was the only one. Mine has it but I barely notice it anymore.

hi... User from my local forum had same problem with You, 1 vertical grey line on left side of screen.. it only appear when screen start getting heat and temporary disappear after long idle.. but he said after 2-3 months that line disappear permanently by it self... maybe it is some kind of glue...?
Been using my nexus 4 for a month and noticed this just a few hours ago. Scared the **** out of me and still am. But just to confirm, this is common on our phone....right?
