The keyboard backlight and the backlight of the capacitive buttons is controlled by the light sensor on the phone. It my living room at the moment. The system can't decide whether the backlight should be on or off. It's really ****ing annoying. It turns on then off again about three times per sentence so far!
Why can't it just be ON when the screen is on and OFF when the screen is off? I don't even have automatic brightness on. The tiny amount of power wasted when your in bright light would be worth it.
I've also seen the keyboard backlight stay off at times when it was quite dim where I was; times when I really could have used it!
I don't understand how this sort of crappy behavior gets through HTC quality assurance testing. Don't they use the phones before just shipping them out?
EDIT: Oh, hey! Problem solved. I put a small piece of black electrical tape over the god damn light sensor. >.<

Lol @ tape. But I cant really say anything about the hk light because I dont use it alot but, there was an app that was for rooted g1 that could controll the backlight of the keyboard. Maybe when the g2 is rooted we will have some better settings or an on off controller

I have that same issue (my touch buttons) go crazy when I use the device, they act like the notification light, and I noticed that about the keyboard too...
The phone has a **** light sensor overall... I can be in a dark room and the phone would be bright as shyt, conversely if I'm near a bright light, the screen doesn't get bright enough.
Hopefully these problems won't exist on my replacement unit.
It's not the sensor, it's the software. Nexus One had all the same problems until CyanogenMod fixed 'em. Boom, working auto setting, working backlight on capacitive buttons.
Stock 2.2.1 AFAIK still has the same issues.
The backlight on my keyboard stopped working the 5th day I had the phone. The light sensor does suck. I was on a call outside and the screen kept coming on. My cheek kept activating buttons on the screen while on a call. Not good. I'm 12 days into my 30 day remorse period. I'm not sure if I'm sending this one back for a replacement or just calling it a day altogether...
30 or 20 days

How did you get 30 days remorse? I was told it's 20 days when buying directly from tmobile website.
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.
Hello, I think my HD2 have screen bleeding. When i'm outdoor, I have hard time to see anything on display & there is a three white bright dots on display. Can I fix this problem or I need to replace display and digitizer ?
display is quite bad in outdoor bright sunlight so that maybe normal, white dots sound like maybe dead pixels.
Try posting some images of it if you can.
Also look at backlight setting for brightness & see if adjustment seems to work correctly as maybe have issue with LCD backlight !
Like you already are thinking, LCD is needed but some images would be good to confirm this & I would not re-use the current digitizer unless recently replaced & removed without any damage.
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.

There is a setting in accessibility that called color adjusment mess with that and see if that helps it

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.
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.)

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.
