Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.
thx, i hope you can help me solving this problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem

I was just sitting on the couch, and the screen on my phone came on by itself. Not to the lock screen or anything, but the screen looks like its on its dimmest setting (barely on at all) and the search button at the bottom is very dimly lit up. Happened twice in the past 20 minutes...anyone else? I'm going to reboot and see what's up.
Are you using a third party sms app? There's a usually a setting that wakes the phone when a text is received.
I've used Handcent without any problems so far. But to be clear, this 'waking up' of the screen is NOT like when you press the button to turn on your phone. When I noticed the problem the screen was so dim that if you're not in a darkened room you probably wouldn't even notice, it's very faint and the only other thing that was lit up was the 'search' button and it too was very dim. At first I thought it was just the reflection of the tv across my phone screen thats how dim the screen was, but it was definitely on and no buttons being pushed would completely wake it up until I pushed the power button to turn on the screen completely like normal. Weird....but after a reboot I didn't see it do it again. I'm wondering if others might not be having this issue and not even have noticed, thus poor battery life for some people?
This happened to me once before. A rebooted fixed the issue for me too.

Have you used one of the temp roots. I had the same problem when I used one of them and when I restarted the phone it seemed to clear up the issue. I have noticed that powering of the screen while its in 3D mode can cause weird issues too sometimes.
Strange. No this is a stock device I haven't tried the temp root yet. Since the reboot I've been watching it closely and it seems to be fine. I suppose this thread should have been posted in with the one already discussing bugs, but I wasn't sure. Thanks for your kind replies!
I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.
Hi everyone !
I'm new here (and not a native english speaker, so apologies in advance for any grammar mistakes)
Before making this thread, I looked for info here, but I'm not sure for what to search.
I'll try to explain my problem here.
I bought a Galaxy SIII from my provider 3 weeks ago and everything looked fine, till last week.
Some times to time, with no apparent reason or cause, while my phone is on sleep mode, on my desk, or in my pocket, playing music, I have the following problem: when I push the on/off button to wake up my phone, my screen is turning on, taking me to the lock screen.
But, my screen brightness is very low, like set to the minimum.
And when I draw my unlocking pattern, screen goes black.
Bottom buttons are lit and my phone seems to be OK, I can feel haptic feedbacks.
But the screen is black.
If I push the on/off button again, screen stays black and bottom buttons are not lit anymore, as a usual Sleep Mode.
If I push on/off again (depending on how much I wait between 2 on/off):
- My phone awakes from Sleep and takes me again to the unlock screen, brightness still very low. And after the unlocking pattern traced, black screen again
- If I didn't wait enought after putting it into sleep mode, in this case, I don't have to redraw the unlocking pattern. I'm back to my home screen...
for 1/4 of a second, stilll with brightness at the minimum. And screen goes black.
And after a serie on onoffonoff, boom, my screen is back to full and normal brightness and everything is OK.
At the beginning, my phone did that once in a while. I thought at the time ti was after pushing the on/off button while using a CPU/RAM hungry app, my phone struggling to recover....
But now, it's totally random.
Depending on .... I don't know what, I have to do the onoffonoff thing 2, 5, 10, 50 times in a row so my phone can recover from is half comatose.
Yesterday, I could not use my phone for half an hour ...
and if someone calls me, I hear the ringtone, but screen stays black.
I can answer the call (but not knowing who's calling) by sliding on the part of the screen where the slider normally is.
Funny thing is about removing the battery. It doesn't solve my problem.
When I do so, my phone boots, I see the "Samsung Galaxy SIII" boot screen, on low brightness (whih is not normal ...)
After that, I normally have another boot screen with my provider's logo and tone. But screen goes black again (but I still here the tone)
Then I realized it started to happen when my phone proposed me a Samsung update.
I tried to reset my phone to factory settings but it didn't work, the update was still here.
For a while I thought my problem was solved, because my phone behaved normally for 3 or 4 hours, without problem.
But it came back.
I found on the internet several "almost-same-problems" without proposed solutions.
Like checking if the proximity sensor was blocked by a protective transparent plastic sheet, or a case.
I tried to to remove mine.
Didn't work.
Some people said it was linked to their phone trying to acquire a wifi network.
My wifi on or off, withiin or without the range of a wifi router didn't work ...
I tried to note things down about what I did, when, how, app launched before the problem appears.
I checked battery info (temp, voltage, etc).
No pattern emerged.
So.
Hs anyone of you enountered the same problem ?
Do you have ideas, solutions I can use ?
Or maybe a voodoo prayer ?
I could sent it back to my provider which will bounce it back to Samsung. But it will take ages (3 to 4 weeks ...) :'(
Thanks in advance !
do a factory reset, go completely stock
if that doesn't help, send it in

That's what I did.
I tried by going into the Parameters menu, and reseting.
I tried by booting my phone with Vol+ / Home / Power buttons to access a console mode and do a wipe data/reset.
The problem is that my phone got an update like one week ago from a 4.?.? to 4.1.2.
And even with a reset, my phone reboot with the 4.1.2 version, which seems to cause this problem.
Or maybe not, but I can't be sure.
As I said, after a factory reset I did yesterday, everything went well for 3 or 4 hours and the problem reappeared.
send it to the service
Hi everyone
I've been having some odd issues start occurring around a month ago on my Galaxy S6 Edge 64GB (G925W8):
1. Auto brightness turned on - Screen flickers between low and high backlight very quickly, mainly when outdoors.
2. Home button stopped working completely for 8 days (fingerprint scanner on the button still worked) but temporarily came back last night but is now again unresponsive to presses.
3. Power button intermittently works, 75% of the time I connect to charger it will start to work again for a short time.
Any ideas why these issues would have started occurring and are there any fixes? The only thing I can think of is that I flashed 6.0.1 (6.0.1 EastLink on to 5.1.1 Rogers) on to the phone but I've re-flashed with no luck.
Cheers
1. its the outdoor mode that makes your screen flicker. turn it on manually and try to change brightness, it will be the same

You're right, when I change the brightness on the slider, the screen doesn't change at all. This is the same even if I'm indoors.
Any ideas how to disable outdoor mode? I cannot find a setting for it anywhere.
Turns out the home button was "worn out" when I took it in for repair for a phone around a year old!
Unfortunately, a broken home button also means the screen and sensors need to be replaced too but luckily I managed to get the repair done for free by Samsung.

I purchased my S21 about 5 weeks ago and I am not sure if I have been experiencing this issue since I bought it but in the last week, I have noticed this issue. When my phone is locked, the AOD will either show for a few seconds to a minute or just won't show. I've ensured it is set to always show, power-saving not set to turn it off, no Bixby routines and any updates are installed for phone/AOD. I've even factory reset my phone and removed the case and screen protector and the issues are still persisting. Does anyone else experience this issue?
Disable all power management... it screws up all kinds of things.
Does AOD show if you tap the screen?
I have disabled all power management that I am aware of and still experiencing issues. I've set it to show on tap and while it worked the first time, subsequent taps do not show the AOD
Video demonstrating AOD tap to show issue
Sounds like a firmware glitch or the flash was corrupted.
Double check all AOD and screen lock settings.
Try turning AOD always on.
Try disabling screen lock... a lock out is the last thing you want anyway.
Play with it... Android's wuv attention.
The case or screen protector won't do this more than likely.

I normally use AOD always on, I'd tried the tap on the option to test. Going to try flashing it today to see if that helps despite the factory reset not helping.
So I've flashed the stock firmware back onto my device and the issues are still persisting. I've contacted support through the Samsung Members app and it's been escalated to the Research and Development team and am just waiting to hear back.
Did you update any Samsung apps after the reload before testing it? Go with the factory app loads.
Try disabling the lock screen... they tend to end up locking out the intended user anyway, sooner or latter.
If no one else is having this issue it very well maybe a hardware issue.
Did you ever wonder what happens when one or two micro transistor junctions out of the millions in a phone fail? Yes, well...
Unfortunately I can't recall if Samsung apps updated before I tested. I've already factory reset a few times so I'd rather avoid that for now. I've noticed the issues occur when using auto-brightness on AOD in lower light settings. When I say lower light, I mean in my study during the day which I never experienced issues with on my S20 FE. I've sent a report to Samsung Members and am waiting on them to come back to me.

Did you ever get this fixed. I have the exact same issue on my s20 ultra
Edit: Nevermind just fixed it after 3 days troubleshooting. Oddly it was the the disable AOD while in power saving mode that needed to be disabled even though I don't use power saving mode. Samsung never seem to amaze me with these dumb persistent bugs.
Glad to see you solved the issue. I'd already confirmed this setting was off for me. It's still happening. Looks like it's something to do with the level of light detection as the issue only happens when I have auto brightness set for the AOD. The problem is it's not even that dark when it's happening and never occurred with my S20 FE.
