Last night, I went to use my night clock app with my new LG v20. On my Note 7, the screen was totally 100% black except for the numbers.
On the v20, the entire screen was stil lit - faint, but clearly still lit up in a light light grey.
Is this just how an LCD screen works, or is there something I have to do in order to get the rest of the screen to go off.
(Note, this includes the 2nd screen which was also lit - and I had the brightness at 0%).

BTW, this may need to be a separate thread - on my phone I notice that the auto-brightness tends to be too dark. Any way I can adjust it to be brighter when in auto mode, or should I just go to manual ?

Try turning off second screen and see what your results are.. Second screen has a seperate black light that slightly bleeds out to the rest of the screen. It was horrible on the V10 but much improved on the 20..

The night clock app has the option to turn off the notification, which also turns off the 2nd screen.
...oops. It did, until I followed your suggestion in the other thread about the more setting to enable time/date when in full screen or notification bar hidden. I'll have to get into the habit of turning *off* the more setting at night.
(Either way, doesn't help with the slight gray background color. I can probably just get used to it as long as I'm not damaging the screen by having it slightly on all night. I need to google if LCD screens have burn in problems I guess.)

Maybe I should just start pm'ing you all my questions

Use comfort view on low or medium. Will help lower the ~9000K color temp some and help blacks a hair. Faint glow is typical on LCDs. Higher quality LCDs and higher quality led's can help. Lg skimped here. Sucks they didn't even give us color modes to pick from. The colors are waaay off. But using comfort view dims the blue pixels and helps considerably.

That's just how LCD works, they need CCFL or LED back light to lit up the screen, it's not possible for it to be completely black while turned on. With AMOLED the individual pixels can turn off itself which is why the black are blacker on them. OLED screens also have very high refresh rates which eliminates flickering, this is good for people who are concerned with eyes health.
Lcd doesn't get burn in, but it can get ghost image retention. It was f***ing horrible by the end of my V10 usage.. Never had the problem on the G2 3 or 4. Just the V10, even after factory resetting.

Had the same issue my V10, that is my biggest V20 concern. . My v10 was not even a year old.
I get the engineering and cost reasoning, but not sure I like the lcd screens.

Hi
not sure if anyone else has noticed this but it seems that the call end button, the button to view the dial pad and the button to view speaker options are burned into my screen!!! viewing in most apps it is not noticable but if you open internet explorer and go to a new page without loading a website the images of the buttons and very visiable in a brownish color I have had my focus since it was released in the US, I have also checked my wifes focus and it also has this burned into her screen.. Has anyone else noticed this?
Yes, I have the call tile, message tile, and the little circle/arrow burned into my screen. As you said, it's only visible on light colored screens, but it is visible. Unfortunately, unlike the temporary burn-in on new plasma tvs, this burn-in will not go away.
If you want to see something really bad, go up to the at&t store and check out the Focus that's on display. The Focus at my local at&t store looks horrible. I can't imagine anyone wanting to buy that phone if they saw that display model...
edit: by the way I love your weather app, I have had a few problems with it over the time i've used it, and you have always been fantastic with your support. Thanks!
Are you using blue tiles? I heard Blue OLEDs burn out faster than other colors and changed my tiles to green.
I have been using the brown almost exclusively; occasionally I'll go with blue, green, or lime, but the brown just looks the best to me.

thanks for the comment. on to your screen you have the actuall tiles burned into your screen? wow i only have the call end and function buttons burned i think its related to having my display on bright i took it off the automatic.
It's actually not the tile, it's the icon inside the tile that is burned in, but it's only visible on white screens. It's still quite annoying. As soon as the hd7s is out I'm going to compare screens, if the slcd is close to the samoled then i'm jumping ship I think...
and yeah my screen is on bright (not automatic) also. I think my problem is that I have the time out set to 5 minutes, and I never locked it myself

Based on HTC's latest track record with the Desire HD and Inspire 4G, make sure you analyze the viewing angle of the HD7-S. HTC has said it will have a Super LCD but, according to an answer they gave to a customer complaining it wasn't true S-LCD tech, the display will likely be what HTC is calling "Super" LCD...meaning it is their name for the super-sized display...and having nothing to do with true S-LCD tech.
If the viewing angle isn't as good as the iPhone 4 or Focus...or other SAMOLED/AMOLED equipped devices...then it isn't the higher-tech display but just an ordinary non-TFT LCD.
Super AMOLED is a great screen. But the pixel life span is still way short. The Blue pixels are the shortest. The old stats are 2000 to 4000 hours. New information point it around 10000 to 14000 hours. But Samsung didn't release any spec on this.
You should always keep the screen dim and keep it on as short as possible. Reportedly use a red theme will not only preserve blue pixels but also prolong battery life.
No burn in here. I have the phone set to turn off screen within 30 seconds, and have always used Lime colour tiles since it matches the Xbox Live tile.
Just a follow up on this issue, and possible a "what not to do" post. The burn in on my screen is getting worse. On a white screen, I can now see the phone icon, message icon, small circle/arrow, the word calender, and my google mail icon. I have the screen set to time out after 30 seconds, and I have the brightness set to high (not auto).
Anyone else seeing this?
I could have swore that on my first Nexus device (RMAed due to bad speaker), I could turn the brightness all the way down and use the tablet on the lowest setting.
On my new Nexus (no issues so far), if I turn the brightness dial all the way down, the backlight totally shuts off, causing the screen to be impossible to be seen.
I'm not RMAing this one because it's perfect otherwise, it's just very weird behavior
I got the brightness on mine all the way down & the screen isn't off.

Did you find a solution?
I have the same problem. If I turn down to minimum brightness (10% or less) my screen goes black. The only way I can see what's on the screen is if I shine a light, and then I can barely make out what the screen says. I assume this is an easy software fix. Also, if auto-brightness is on and I'm in a dark environment the screen will occasionally dip to the lowest setting and turn off.
I'm on my second device also. My first one had bad screen lift, flickering and occasionally screen glitches with black lines flickering through the screen. This one had no noticeable screen lift out of the box, but I'm reserving my judgement, as the device I just returned was fine for the first few hours and then got worse as I used it more.
I have both devices side by side, since Google mailed me the new one first. Comparing the two, I notice the old one's screen is slightly brighter, maybe about 10% or so, but definitely noticeable. Also my new one has a little bit of bleeding on the left side; not terrible as some pictures I've seen, but definitely there.
Update: The screen flickering returned, so I just requested a second replacement. This is actually ridiculous.
I got my S4 last week and it's great. This one doesn't have any lag, or at least not anything that concerns me. However, it does have screen issues, especially with the light adjustment. Sometimes the screen will randomly go full brightness for a second and then go back to normal, I notice this when accessing messaging sometimes. I know it also does this for Instagram, but it is suppose to do that.
Now, sometimes it seems like it does a colorshift. the screen will appear less blue and more yellow. It did this when I was accessing the facebook messenger app once and maybe another one. I might be making this up, but it just seems like the color changes ever so slightly. Also, once in a blue moon when it is adjusting screen brightness, all these vertical black lines appear for a microsecond on certain parts of the screen, it seems like an even distribution of lines. Reminds me of something old game boys might do.
I am very happy with the phone though, and I don't want to switch it if I don't have too. However, if another version might not have these issues, I want to switch ASAP, I only have a week left to swap for a new one. After that, my 14 days are up and they said they would only give me refurbs. :[
Do it.
I'm stuck with a defective screen 16GB because the 32GB did not come in on launch day which was my last day to return.
My only option at this point is to get another 16GB that's refurbished from warranty.
The irony in all this is that I manage the kiosk where I purchased the phone on my personal account.
My employees' phones and demo don't have the same screen issues I have.

I will check out the settings. The events that this glitches happen are rare, but it has only been a week and they have happened numerous times. The auto lighting adjustment sucks, times when it should be bright it's not. Plus the black line stuff that happens sometimes. If all of them experience this I dont want to trade in for another one. I don't want to risk trading my working phone for one that won't work so well.

I would swap it if I were you.. I came from the HTC one because of repeated problems and switched to the s4... I've only had it a few days now but have only experienced some lag (fixed by tweaking settings) and the auto brightness is a little slow to adjust sometimes (I've always though this about all my Samsung devices).. But no color changing or bars appearing.. Just my 2 cents..
Sent from my SAMSUNG-SGH-I337 using xda app-developers app
that is partially due to the type of color meter and ambient light sensor type (should be a 40-something segment black and white unless my info on the sensor specs are off. i believe apple has designed a proprietary multisegment rgb meter for theirs). b/w meters get lumens correct, but not perceived brightness (human eye is not the same as a sensor).
the color changing issue you are having may be due to the display mode being set on auto (start, settings, display mode) and under lighting that the sensor cannot correctly meter for (fluorescent lights flicker at the same hertz as your AC current, and are actually pretty dim and WAY off for color balance, so that SHOULD throw the sensors off continuously, which would lead to auto brightness hunting and inaccurate selection of the 'correct' color mode).
try turning auto brightness off and color mode to professional photo or movie (i use move as its very flat and closer to real colors). there ought to be a way to trick the ambient brightness sensor to sample and average at a faster rate, and ramp up/down more smoothly, but i cant code for android otherwise i would have been working on one.
i work in tv/film industry on the sensor/lighting side btw. if the issue goes away, turn on auto brightness and check it out under NON FLUORESCENT lighting. if its gone, it was probably the display mode changing along with auto brightness.

I had no idea the S4 had these options. I guess I am used to my Atrix which didnt do much. I went in and adjusted the settings. The auto screen brightness never really did a good job, I feel that it is way too dim in situations where it should be brighter. I will text your advice the next week and see what happens. If I still get issues, I will return it as I have one week left of my 14 days. Thank you very much for the excellent advice!

no problem; the auto brightness on the GS4 is only slightly better than the Atrix 4G (had one too), and same as the GS3. The color mode thing (which is awesome; closer to real life colors versus waaaay oversaturated screens on most phones. also check power saving settings.

Well, I have not seen those black lines since I turned off auto brightness and turned off the screen automatically doing it's own color adjustments. I will turn these back on to see if I can duplicate the issue. I do feel that I have more lag now, but I could just be paranoid.
OK, when I am using my Facebook Messenger App, sometimes these black lines appear horizontally across the screen on low brightness. However, sometimes they dont. I dont want to call them black lines, but maybe I should say they are ghostly tv lines that are barely noticeable. Ideas?
Could someone explain the defective screen issue?, mine looks great...
The phone works great most of the time and is totally useable, the only issue is that sometimes it does these weird things as I have explained. Tomorrow is the 14 day mark, so I am having a hard time deciding if I should switch for another one just in case, or assume all of this is normal and hope the phone lasts me 2 years.

Could possibly be a GPU issue. Have you had any problems playing heavy duty 3d games?
Sent from my GT-N7100
No problems playing the Iron Man 3 game, everything seems fine.
It seems like any time the keyboard is pulled up, the screen shifts color to something more yellow. all of the keys go from a nice grey to a off grey yellow tint color. During this transition, I can literally see the screen transition as weird lines appear for a fraction of a second, like switching channels on an old TV. I tried recording this on my DSLR 1080P camera but it could not pick up the color change visibly. I might try again. It does this on Google Chrome, Facebook Messenger, Snap Chat even. sometimes it color shifts even when the keyboard is not involved. I have the auto adjustments on the screen off and the color set to Standard Mode.
The ATT store said I am a day out of my 14 day limit and there is nothing they can do. They said I have to talk to warranty and see if they will be nice enough to send me a new one. I dont want a refurb, last time that happened, I went through 4 of them. I talked to ATT support and they said they would extend my 14 days another 3 days but the ATT store said I was out of luck for an exchange for a new phone.
So no one elses screen color shifts to yellow when the keyboard pops up? Mine does this now all the time, mainly in low light. It might do it in all light situations but in sunlight I prolly just can't see it. It's incredibly annoying because the screen itself wacks out every time it does it.
Hi 2 All,
I have galaxy s4 installed offical 4.4.2, when i open setting or task manager in very dark place, i saw abnormal brightness in background.
i thinks it should be black as it is amoled.
is it normal or serious?
is it sign of screen burn?

Open a completely black image. Download a solid black JPG from google as your test. Do the same thing with a completely white image.
Look at those images in full screen mode.
If there is burn in (which CAN happen on an LED screen, though it's actually pixel fading rather than burn in) you should be able to notice it with this test.
If you see fading in the white image, or general non-uniformity in the brightness, it's a sign of fading. (burn in)
If you see a ghost image in the black image, then something is wrong. It means the screen is lighting up when it shouldn't be.
You should not be able to see a residual image on a black screen like you used to with an old CRT computer monitor. The burn is doesn't work that way. What happens is the pixels lose some of their brightness over time. It's subtle, and if the screen is fading uniformly you probably won't notice. But when 1 spot isn't fading, you notice it quickly. This is most commonly seen with the status bar. If it's always black and the area right beneath it is always colored, then the black status bar wont' fade and the rest of the screen will.

Thanks Sir,
actually it was lcd problem
So mine turns pink/reddish when setting the lowest brightness setting (ambient display on) - you have to be in a pitch black or very dark room.
When its off, it still does it but its not that bad.
EDIT: If yours does turn pink, will you RMA?
Mine does this as well. I rarely ever see the brightness go that low so it doesn't bother me that much. However what does bother me, is at 50% brightness unless i am looking at the screen dead center the screen has a redish, bluish, or greenish hue on it. Was very yellow the first day I had it, but the yellowish hue is gone.
I have adaptive on. Last night I set my brightness all of the way down. For the first time I saw a slight pink hue. Increasing the brightness fixed this. I am not sure if turning off ambient would have fixed it. If I see it again I'll try turning it off.
I thought was a known feature of amoled. I'm guessing they will all do it at low brightness.
Mine actually got worse. When I first noticed it, it was acceptable. Now its almost reddish already. Some people say its actually a feature of AMOLED. However, when I tried it on a different AMOLED Screen, Note 3 and 4 - i didnt see it.
No, I tried with adaptive brightness on and off and can find no color changes except maybe a slight blue hue when tilting the device and then almost rainbow effect at close to 180 degrees. Guess I got a good screen.
