they are on by default over here..i haven't used android long enough to change the setting if it even has one so mine has to be default. I have my brightness set to auto but im pretty sure that was default also.

me neither :/
Mine also automatically lights up when I hit the power button. I have not done the OTA.
That's SO weird. After reading the title of this thread, a few seconds later, my lights stopped coming on, too.
Turned it off, pulled the battery, and now it works fine.
ya mine just randomly started working with no reboot ahah..how weird..now to get my ota >/ still havent got it yet
I just came in here to find this thread (how do you search in the XDA app??) because I am using my phone in the dark for the first time (hotel, trying not to wake my girlfriend) and my buttons weren't lighting up.
I did a quick Google search and found they won't light up if you turn the screen on when the phone is plugged in, and this is apparently by design.
For some reason mine never work in the morning in the dark (when I actually need them to), but they always work during the day. I figure there is just some bug with the light detector.
For those having issues with the lights not turning on, are you plugged into a USB cable? Mine do not turn in when a USB cable is plugged in, but they do otherwise.
Mine never turn on at all. They haven't since I got the phone. At first I thought it was by design then I realized how stupid that would be and looked it up. Sure enough here is the thread with people having the same problem...I'm on hold with HTC as we speak...
Capacitive Touch Buttons won't Illuminate
I found this thread in a Google Search and wanted to bump it:
I just picked up my white EVO today. I just noticed my capacitive touch buttons don't light up, though they do function. This makes the phone impossible to use in the dark. I was going to ask if this was a setting I was missing, but after reading this thread it seems like a small bug. Have anyone found out what the status is on a fix? thanks!
Ok guys I discovered that the button lights have a light sensor, this sensor is located under the earpiece speaker on the left side looking at the phone. If you have it plugged in you can cover the sensor up with your thumb and the lights will turn on. The lights also will not come if you are outside or in a well lit room. I hope this helps, and still dont know what to tell the OP as his happened in the dark.
Ever since as long as I can remember, my phones brightness will dim to a brightness so dark you just can't see it. Even if you manually set the brightness, once you lock and wake the screen, it's fine then suddenly switches to dark.
I've used multiple ROMs and they all do it. Is it a device issue, or could it be a kernel issue? I've not screwed with kernels so I don't know if it could be it. If it's a device issue, I'll be getting a replacement ASAP.
Any help is appreciated!
Now that I'm able to Google, I realize it's a common problem with the S4.

The only time I had the screen go dim like you describe is I remember once following a phone call. It goes dark when you put the handset to your ear like it's supposed to, and lights back up when I pull it away from my head. I was stepping out of a truck into the broad daylight when I tried to hang up my phone, I couldn't see the screen very well. The other party ended the call, and my screen timed out while I was squinting at it. I pushed the home button and it lit right back up nice.
You got something going on, and if you tried all those different roms, say... can you nandroid back to stock? Did you try that?
I'd try everything I could on the outside chance of repair instead of replacement. If you get a replacement you might be stuck with that MF3 where you cannot install a custom recovery.

Mf3? Is that something new with the S4s to prevent custom ROMs?
It does not go pitch black. It goes very dim every time I wake the device. If you Google S4 screen dimming it's a wide problem.
Once you wake it, it's fine for 2 seconds and dims quite dark. It is not screen timeout/sleep/etc since I can still see the screen.

I'm on MDJ and don't get any auto dimming of any sorts. Auto brightness is off, brightness controls about 1/3 brightness (indoors), but Power Saving mode is on with all three options on.
My S4 is MDL. I found out the problem (More than likely) was the Paranoid Android ROM. I was on ver. 3.69 and since switched to CM 10.2 Nightlies, latest as of today, and no screen dimming. I will install my usual apps and use it as normal and if it happens, it's probably an app. However, the only apps I use are ones such as SwiftKey, LightFlow, ASTRO, Chrome, and Dashclock.
I'm on stock MDL. It has only been occurring since I upgraded from MDB 3 days ago, and is a huge PITA because brightness controls are unresponsive during this time - I go into settings to adjust brightness since I have removed all the brightness controls from the notification panel as they've always worked just fine, and turn off auto brightness, scale it all the way to max, and it is still dim as crap.... Only fix I've seen is to reboot, which is obviously not ideal in most situations when I need to wake the device! I'm using STOCK kernel, STOCK ODEXED ROM as well, nothing crazy should be going on to screw with brightness settings being unresponsive either!

Do you by chance use Light Flow?
I solved the problem. I had "lcd_backlight" control flipped on in the settings of Light Flow. It fixed it. To tell if it's an app problem, just factory reset and try, once you boot up, to lock and wake the device to see if it happens. If it doesn't, it's an app problem more than likely, or even a general setting. Troubleshoot for the win!

I do use Light Flow, but I don't have either one of the LCD Backlight controls enabled, never have and never will, so I don't know how that could be affecting my phone at all.... That's a good start for some, but not for me, unfortunately! Good catch though

I had this issue before on my Galaxy S3. I ended up replacing the front glass because of a dead pixel. Come to find out I had a sensor issue and that was causing my brightness auto going to whatever level it wanted.
Perhaps you're experiencing that too. Haven't heard or read of any sensor issues yet with the S4 but you could be the lucky winner!
Great phone but, it appears to be a bug with the screen dimming.
Regarding settings, I have everything turned off. Adapt display is off. Auto-brightness is off. Auto-adjust screen tone is off also.
I know Samsung displays dim if the phone overheats but my phone will auto-dim even if the phone is cool.
What I've found out is that the phone will only dim "permanently" when the screen is about to shut off.
For example: Set the screen shut off to 30 seconds and around the 28 second mark, the screen will dim for a couple of seconds before it shuts off. This is where the auto-dimming will "permanently" kick in. When the screen dims at the 28 second mark for a second, i'll touch the screen so it doesn't shut off. But by this time, the screen has dimmed already and won't go back to the regular brightness. I have to lock and unlock the phone for the dimmed screen to go away.
This scenario has happened every single time. Extremely annoying.
Anyone else experience this?

Seems like software problem, do you use custom roms? kernels? maybe any app that could control ur screen? try to do hard reset.

Yes, same here. It happens alot. Not every single time, but alot of the times.
Try this...
Hi
As the other user said it might be the software bug.
Please try this app. Disable your auto brightness and install this software https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite
This lite version is free. Try this. If everything works, you may consider the paid version to support the dev guy...
Hello all,
Sometimes when I am on web page or simply surfing facebook and my Note 3 dimms after 15 seconds as set, when I touch the screen, brightness will go lower as it has been set..Than I wait untill it dimms again, touch the screen and it goes to set level.. It happens either when on autobrightness (i am not moving phones position) or when all features controlling screen brightness are off (screen mode auto adapt, automatic tone adjustment, auto brightness, power saving options etc..) No third party app controlling brightness is installed.
Anyone can help?
It didnt disappear after hard reset..
Basically, once again - when screen dimms, sometimes after I touch it, it doesnt go back to the brightness I set manually, but stays dimmer..
Then, after 15 seconds (interval I have set for dimming) it goes slighty dimmer, than I touch the screen, and it goes back to the brightness it should be
Thanks
Maybe your Device ist to hot?
the Software dimm the Display to prevent for overheating.
Gesendet von meinem SM-N9005 mit Tapatalk
I thought also that, but hard reset, no other extra apps installed, and It happens when I am browsing the I-net or chatting on Facebook for example..
It doesnt feel hot at all.. I have plastic case on it, thats all..
Hi, it feels like it has something to do with auto adjust screen tone.
For me it looks like, that even if its switched off, it is working when the screen dimms and i navigate to settings and click on it, screen goes back to brightness where it was immediately...strange..
Maybe some stock app is always using it? Hmmm
Do you have the problem from beginning or after long time surfing?
Try it in cold condition.
My Note reduces the brightness if it's really warm on top of backside, not really hot!
If you charging it at the same time, the overheating comes faster.
Surfing the web is a intensiv work for the CPU

Hi,
I have this phone for little over 2 years. For over 1 week now I'm experiencing my phone not being able to wake up when I use the power button/home button. Whenever I push the button, the screen flashes for like 1s blue color, you can also see that the notification panel is blacked out and part of it green and it doesn't wake up. Sometimes it doesn't even flash. It used to take about 10 tries to wake it up but today I couldn't wake it up. I performed soft reset, I couldn't see the booting animation at all but it rebooted, buttons lit up and I was able to get in. It's like the phone is working fine in the background but the screen doesn't light up. I can turn down/up the volume, take a screenshot, get into settings, open apps, write a message but the screen is black. Even my alarm went off this morning but I couldn't dismiss it.
I downloaded an Always On Display app. Although I don't actually see the screensaver when it's locked, it's still on and it's easy to get in beacuse of it.
It all started with the screen flickering on minimum brightness. In February this year I had the screen replaced for the same issue but this time it's worse because of the blacked out screen.
Any ideas what it could be? Faulty display again?
Thank you

It's over to have this phone for little over 2 years now you should have to change
TIP:
Flash a new stock rom of your phone from sammobile via ODIN.

That would be great, but I'm not a person that buys new phone every 2 years. I was thinking about it though .
When it comes to flashing. Do you think that would help? I don't want to end up with a black screen unable to set the phone up again. Cause overall it's working great .
Hi, i have the same problem, i'm from Belgium, and I have blinking screen problem and wake up screen problem :s
is it a software issue (nougat???)
before the big update (marshmallow i dont have any problem)
i'm on firmware A510FXXS7CRJ6_A510FLUX7CRJ1_A510FXXU7CRJ6_HOME.tar.md5
Turn screen brightness up abit to stop the blinking of screen. It's an issue of the screen hardware itself at low brightness after wear and tear. As for the hanging issue, maybe it has to do with your AOD app? Try uninstalling the AOD app OR flashing a stock Rom OR custom rom OR factory reset and use your phone at a higher brightness that the screen does not blink and see whether it still persists.

Thanks, because of my past experience with the same problem earlier this year I know about that "solution". Unfortunately, it makes the battery die faster as expected. Which is sad because I used it mainly on low brightness. So it's really not a solution at all.
I got rid of the AOD app because I found out that the phone lights up on 2nd try. AOD didn't work at all. I have to wake it up, put it to sleep and wake it up again which is always successful and the screen lights up. The screen flashes white about 3 times in a row now otherwise it works.
I haven't flashed it yet although I wanted to. But I will see what can I do. Thank you though!
I'm having the exact same issue using LineageOS.
It's already been 2 years, but since this thread is one of the first results on Google, I'll gladly add a solution.
Exact same problem for me, went through two screen repairs under warranty, and it would always come back a year later. No difference between Samsung OS and LineageOS, though I haven't tried rooting it.
Found on Ifixit: this issue is related to the AMOLED screen technology used by Samsung (among others). You can look it up, apparently there is a bad (?) voltage management in low brightness which worsen with time.
I could fix it with the "OLED Saver" application on Play Store. It works around this voltage management and allows you to reduce the brightness without the green flickering.
I still got white flashes after the installation, but not anymore the day after. I could even disable this application without the issue coming back.
I don't know what kind of magic cleanup this app performed, but it really is a (screen) life saver.
