I installed a battery booster app from the market, and it had an option to dim the screen, it was on 11%, well i tried to adjust it, and i guess i went way to far and it turned my screen black, i cant see nothing.
im on the Darkstone build.
is there a way to either delete that app or what, i know the phone works as i feel the vibration from me sliding it to unlock from home screen.

The LCD still light up but very dim, so try going into a dark room and wake up the phone. Then you will be able to see the contain on your phone.

Like i said it is BLANK. seriously blank. its not dim or nothing.
Is there a way to restore the brightness on here, because i cant see anything im doin on it.
what you can try to do is, grab a friends phone and try to immitate the same touches on both devices, the best way to do it is by unlocking it, pressing the menu key, click on the corner to make sure u go to the settings, scroll all the way up and find your way to "display" tipically the 4th (or 5th in my case because i have cyanogen mod) and brightness (should be the one at the top) and just try to drag ur finger from left to right to increse it (as it should over pass any 3rd party app) and see if it works, but..... keep in mind these things dependeding on what phone you use to guide you....
screen size
DPI scale
sense??? or not! as settings are different
and other things, also..... when you unlock it make sure its on the home screen
i also believe if you go outside you can see the screen a little bit under the sun, but not completely sure
hope this helps, oh and by the way, if you have a build based on sense go to a sprint store and use an EVO lol, or if u have stock froyo grab a nexus one from a friend and use that (but like i said before, keep in mund the screen size)
yea thats what i was tryin to do. no luck.
I had this problem twice and rejoice, I have a solution!
Simply download "DroidExplorer" for windows.
Boot your phone in android.
Once booted (when your screen turns black), plug in USB, and launch DroidExplorer.
In DroidExplorer, look for the "Screencast" icon (little android icon).
Run that, you will see your screen. Reset brightness to a normal level.
You are saved

When this happens, try shining a bright light on the screen, make sure the device is woken up (i.e. press a hard button) and view your screen from different angles. Even if the backlight is completely off, the LCD display is still active and the graphics elements just about visible.
With this method, you should be able to make enough of your screen to navigate to the brightness settings.
Screencast in Droid Explorer (for your PC) is also a good last measure.
Most apps that control brightness has this problem on HD2, so be careful about going too low in all of them. In Tasker, for example, 30 is the lowest setting that works.
Even the standard screen dimming that occurs a few seconds before screen timeout is not calibrated correctly. In all Android builds/kernels I have tried, the backlight is turned off when it should be just dimmed. Cyanogen(mod) has a setting for the dim level, but the maximum you can use is 26, which still turns off the backlight.
Curiously, sometimes (very seldom) after waking my phone up from standby, the backlight is in a much dimmer state than usual. When sliding the standard brightness from min to max, the actual brightness range varies from barely visible (but still on) to the regular dimmest level. So the device *can* support incredibly dim levels, but I've have found no way of getting into this state predictably. It has happened only 3-4 times over the past 2 months. A reboot fixes it, but I've also gotten out of this state after a locking/unlocking cycle.
So there seems to be several layers to the backlight brightness:
- the actual hardware (which supports much lower brightnesses than we're usually allowed access to)
- the Android API (which probably is the layer turning backlight off below 30, and which occasionally is fooled into using a much dimmer range than usual)
- whatever app providing the GUI (usually showing a range of 0-100% or 0-255).
Does anyone know if there's a reason for the threshold? Is it somehow risky for the LCD display hardware to be very dim?
have android desire build on my hd2 and it works great...if i put my phone in standby for a few seconds it comes back on just fine but if its in standby for a few minutes only the keys light up and i have to pull the battery..i was reading some posts and thought i saw something about deleting the data.img....was wondering if this was the solution to the problem or something else..
If you have a black screen and the button lights are on, you can stick it under a bright light and turn it on. It should come on after that. If that's the case then turn off automatic brightness and see if that corrects the issue.
auto brightness wasnt on when i went to go change it...i flipped to it just to see if it would do it but it does the same thing..if in standby for too long,the buttons light up and the screen lights up black but thats it.

hmmm..... have you tried deleting your Android folder and installing another build?
Iam having the exact same problem.
Screen stays Black. Lightens up but nothing comes on...sometimes its fine.
but sometimes it just stays black untill i pull out the battery
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!
so im trying to figure out whats wrong any suggestions would help ill add pics in the pics i add thats all i get as far as what state the phone is in black screen just a vibrate when i turn on the phone and a few lights thats it. OK the pics won't upload but like I said when I start up phone it vibrates and notification light fades in and out like its starting up now that little blue light stays blinking so I know its on and the soft keys are responsive just a black screen nothing else works
Have you tried to get it into recovery mode?
no it doesnt work screen completly black all i get still is the little blue light on the top left that blinks and soft keys lights up thats it cant do anything else

I would still go through with trying to get it into recovery mode even though you say screen is off.
so i tryed to pull battery and tryed recovery mode no sign of any lights at all on screen screen stays dark all phone shows is soft key lights and the little light blue light that blinks on the top when phone is on and every time i go to touch the phone it vibrates as well

If not try connecting to a pc and run kies to see if it reboots that way.
If it is rooted try to reflash thru odin.
i dont know if the phone is rooted or not like i said i cant see anything to determine that can i be having a lcd digitizer issue?? i tryed running with kies and it doesnt connect my pc picks up the phone though not a problem i can go into the files on the phone but there isnt much inside the phone eithier
How long have you had the phone under 2 years still under warranty.
i didnt buy the phone nor do i know who did so i wouldnt know and in addition the screen is cracked so i dont know if they would even cover that by any chance do you know where i may get a cheap lcd digitizer ?

That was my point..
It must be broken or the digitizer connections must be loose..
You said it..its broken
Check ebay or somewhere..you'll find plenty..

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.
