For some reason my device has suddenly started switching to the minimum backlight setting whenever it's switched on. If I go to the backlight settings and then adjust the slider it will stay at the selected brightness until it switches off. When it switches back on again it's at minimum brightness and I can hardly see the screen!
This started happening after I installed and then removed PocketZenPhone.
I don't really want to hard-reset the device unless I absolutely have to - does anyone know what registry key sets the default switch-on brightness?
Thanks,
I dont have the solution but I have had the same problem intermittently. Can be really aggravating in the dark because it can be hard to get to the proper screen to increase the backlight. Hasnt happened in a while. Have not been able to figure out what triggers it. Have not installed PocketZenPHone. Curious if anyone has an explanation.
yah, i've noticed this to, sometimes i'll hit the power button to take it off standby and the backlight would be off. first couple of times it scared the hell out of me cuz i thought the screen had broke or burnt out.
also i noticed the version of spb pocket plus i'm using (3.04 build 4195) doesnt adjust the backlight brightness.
Now that you mention it. the SPB Pocket plus backlight does not work for me either. Strange...
Well I think I've managed to "fix" this by setting the following;
Backlight Settings:
On battery power, turn off backlight if device is not used for [5 min]
Turn on backlight when a button is pressed or the screen is tapped
Power Settings
On battery power: Turn off device if not used for [3 minutes]
I think the key thing here is to have the device auto-switch-off BEFORE the backlight timer kicks in. Since setting the above three settings I have not had the same problem again.
Ill give it a try as well.
Hmm...maybe someone can help me. One day, my backlight timer settings when the PDA's not plugged in reset to 10 seconds (in the registry it has it as 7 seconds). I'll go in and change it to 2 minutes (the original setting I had it at), but the minute I turn it off, it resets back again to the 10 seconds setting. I even tried going into the registry and changing it, and it resets it back to 10 seconds. I suspect it may have something to do with an entry in the "scheduled tasks" but it looks like a complete mess. Is there some kind of scheduled tasks cleanup utility?
Thanks,

hello i have the same problem using phothet with WM6
Thanks

I had the same problem often about 15 months ago - it happened often each day.
I posted herw but had no joy with a solution - but then found one on Modoco (i was looking about March/April 2006).
Even with that - it has still done if perhaps five or six times since - and basically makes the phone unusuable if it happens somewhere or time with poor light.
My KJam backlight keeps changing by itself to dark
Suddenly my KJam backlight always turns to low without me doing so, then I have to change it to high, barely can see what I’m doing as it is almost black. This is kept happening especially after I installed Pocketweather. I reinstalled the Rom, it worked fine then suddenly it is back again when I switch the screen off, or automatically it is switched off, the backlight slider I find it at the lowest end.
Why thus is happening, it’s driving me crazy, please help me
so I put the dimming to be after 30 seconds, which works.
however I put it to shutdown the scree after one minutes, however it stays on forever, unless I physically press the hang up key, the screen will be on all the time.
the other question I have.
2- When I search on google, and press on one of the results in opera it takes me to the definition page, rather than the actual result that I wanted
3- is there a fix for LED notification, I installed the cab to fix that, but it didnt make a difference.
4- the pink spot at the middle, I searched around but didnt see any real solution
can anyone help please
regards
While I can't offer any help, I can feel your pain! I too am experiencing this f**ing event! I placed in my pocket before boarding for a 6 hour flight yesterday and found it still powered on when the flight had ended. I had just enough power to make and receive a call! Great.
I've double/triple checked my settings after this same thing happened to me previously! WTF!
edved.
i had the same problem what you need to do is to change the screen light setting in the settings menu

Ok. I'll try your suggestion, but please tell me what the screen light setting should be?
Thanks.
just go to the backlight settings, tap ok and it seems to be fixed..
(but offcourse check if is set to turn off after a minute or whatever your needs are)
I experienced this yesterday.. just like in normal windows, some functions just stop working with no particulair reason.. I don't really worry about it.. probably fixed in the next rom.. same sometimes happens with the screen lock, sometimes it's gone.. also after reboot, althought I find it more convient that way, it can be fixed by locking the device manually.. this does proof we can disable the device lock somewhere, I really don't need it in the case I use, the power button is enough..
good tip to always push the power button before putting the device away.. saves a lot of battery too then to wait for the minute before it powers of by itself.. the large screen is the battery's biggest consumer.. this way you also don't have to trust the automatic power off.
problem is pushing the power is not enough.
because if there were any even that woke the phone up, it will never shut down the screen unless you saw it, and do it manually

no the automatic power down is seperate from the screen lock, but for some reason they connected it with the automatic power down and left the options to choose out.
hey i downloaded extended control power widget. and when i pressed the brightness button. the screen went black and touch doesnt seem to respond (tried tapping the same place to bring it back...)
the phone is still awake as i can hear lock sounds and such. but i cant get brightness back up at all.
is there a way to fix this? i would assume adb or something
or possibly a script i could load on reboot into android?
Try holding your phone under a very bright light and play a little with the angle. You should see your widgets. This fixed it for me

thanks, that worked. it at first seemed as though the touch wasnt responding.
but it seems i accidentally moved the widget in my frustration LOL so i was hitting a blank spot.
I know this is probably a basic question, but everytime i switch the tablet on now or switch the screen back on once it's gone off, and once i've slid the unlock button up, i keep getting this search history page immediately after... I've been through every damn Google setting i can see/think of and yet everytime it switch the screen off and back on, there it is again. Please help as it's driving me insane. It just used to unlock as usual and display the wallpaper and icons on the home screen, i don't know what's been changed..
Doesn't matter... I've sorted it..
Hi Guys,
got my S8 about 6 days ago. it's been working flawlessly and i've been really enjoying it.
Yesterday i took it out of my pocket and the screen wont turn on. it's completely black. i can hear it unlocking, i can even answer phone calls on it and talk, but again, can't see anything. I've tried hard resetting the phone (volume down & power button), it completely reboots, which you can hear the tune of it starting, but nothing. I've tried plugging it into the charger, still nothing.
I'm new to the samsung party, so i did some research naturally and found this was a common problem on the previous generations. Most cases were solved by removing the battery and reinstalling. however with this model, i can't do that. I've taken the phone back to at&t to get an exchange, and because i "preordered it," i need to go through customer service, which they are telling me i need to send the phone back, and because i do not have the original shipping box, i need to pay a 15% restocking fee to return the phone. THEN, they will take up to 5-7 days to send me a new phone. As you can tell, i'm a bit frustrated.
Any suggestions?

Tried it, nothing. I can feel the phone giving haptic feed back and clicking as i click the virtual home button too. I held it for upwards of 30 seconds.

darn. my brothers did that, and that is how he got it to power down. then it powered up normally
have you tried:
Vol up, bixby and power for recovery
Vol down, Bixby and power for download mode

I tried all of that, however, i can't see the screen. So I'm not sure where i stand when i enter those modes. When the phone reboots normally, i have to enter my code manually the first time, which i can do, just by memory of the button placement on the screen, but as i said, can't see anything. I'm willing to try anything. At this point i'm just letting the phone sit idle and let the battery die, hopefully that will do something.
You have a month free of Samsung Premium - sign up for it, call samsung and they'll take care of it

Happy Ending! Cheers

Damn, I got the exact same behavior on my S8+ today! sitting in the couch watching Hockey and I got all excited after the Caps crushed Penguins tried to send a text to a friend but the screen won't turn on? Tried everything above but screen is black..SUCKS!
I just got the same thing ..tried everything ..however the download did work ..and a blue screen came up and asked if i wanted to download so i pressed yes ...so we will see what happens
A friend and I both had this happen within a week of buying the phone. What it turned out to be in both our cases is the screen was on the very lowest brightness setting. We did not set this. Somehow it happened spontaneously. Go to the darkest place you can find and you should be able to return your screen to a normal brightness. I have a feeling this is going to be a recurrent problem with a software fix in the future.
I had a similar issue. I set the power saving option and it looked like the screen turned black. Only after going to a dark room could I tell it was on. It was a new level of dark I never seen even if you consider setting the brightness to its lowest setting.
same here,
during typing screen freesh and black out.
as death as a door knop. nothing worked none of the mentioned options by Samsung relieved me from a black and dead screen.
its now being collected for repair,
lets wait and see
Same here also.
After 7 days of using it I picked it up to check for notifications just to see the black screen.
Never let it fall or anything.
Unfortunately I will not get a replacement from my dealer but a repair. Let's see if we get a BSOD-gate ****storm with this.
Another BSOD here.
Less than 7 days of normal use, screen seems to be deade. I have haptic and sound feedback. Even the alarms are ringing all day long and I can't turn them off.
Now I'm waiting for the vendor to collect it since I requested a return due to defect.
I FINALLY understand what is going on with Samsung Black Screen of Death-- how it happens and what to do.
First off the bat -- IT'S A DESIGN FLAW IN PHONE! Here is what occurs to induce the Black Screen.
1.) As you lift the phone to your ear, the top of your ear touches the screen. The screen "understands" this to be your finger drawing down the "notifications" bar.
2.) If your ear comes off of the screen, when you place the surface back to hear, the screen "understands" this to be a 2nd time pulling down on the screen.
3.) At this time, your screen brightness "slider bar" is sitting smack dab in the middle of the screen. This 'slider bar' controls the brightness, from very bright to the screen turned off. Slide to the left, screen gets dim. Slide to the right, screen gets brighter.
4.) If your ear next touches the screen, it is almost always on the left side of the screen - no matter whether you are left or right-handed. The Samsung S8 + interprets this 3rd contact to the screen as you "instructing" the phone to turn the screen intensity to "off".
5.) You now have the "Black Screen of Death".
You can simulate this with just using your finger on the screen. Pull down the notifications bar ONCE. Then do it a SECOND TIME. You will now see the screen intensity "slider bar" before your eyes. It is the one with the half sun / half moon icon on the left side of the bar. If you move the little blue bar with your finger, going right to left, you will see the screen go dark.
These are the exact same movements your ear traces on the screen as you use your phone to answer a call or to talk on the phone. 3 accidental touches and the screen is BLACK and you don't understand how it happened.
This is a design flaw in the software. Samsung needs to change how the sllder bar controls screen intensity.
If you go into a very dark place, there will still remain a very faint glow from the screen. All you have to do is 2 finger swipes down, then with your finger push the slide bar back to the right- and VOILA -- you can see the screen again.
Hope this helps everyone until Samsung fixes the problem.

Doesn't the S8 have a proximity sensor like the iPhone to determine that the phone is being held up against someones ear?
I FOUND A RECOVERY FROM THIS!!
I just got the Black Screen of Death for the first time after owning the phone for 2 weeks - pretty alarming when the phone is unresponsive, you can't reboot with the power button, and you can't pull the battery. (Coming from an S5, this is my first phone with a non-removable battery). Even though I knew my phone was fully charged, I tried plugging it in, and didn't even get the red LED. Not good.
After a little Googling, the solution I found that worked for me was: Press and hold Down Volume + Power at the same time for 7 seconds.
This brings you to a screen with some options, the first being to reboot like normal.
Volume toggles up and down between the options, but be sure not to choose option 2, which is a factory reset!
The Bixby button selects, so I just clicked on option 1, and I was back in business.
This apparently does a "simulated battery disconnect". Assuming it was some sort of firmware crash, this should bring you back to life. It did for me. There are other suggestions on the page if it doesn't work, but I was back to life after step 1. Hope it helps...
