As we all know(or should know if you read around the forums) that there is an issue with "sod". Now these sods are not the same as the sod i was familiar with before 4.2. Before 4.2, the device(s) were for all intensive purposes not alive. Sure you could connect to adb, but the device was "dead" until you pulled the battery and rebooted. But with these 4.2 "sods", the device is alive, with the exception of the screen not being able to turn on. Phone calls and messages still come in. notification sounds still play, and you can use the volume buttons to raise/lower the volume. But you still have to pull the battery and reboot for the screen to come back on. Running logcats via adb doesnt seem to show anything related. Well, ive found a way to reproduce these 4.2.X "sods" while the device is awake with the screen on. I can reproduce it at will, and have had other users confirm this. What i do is this.. I go into the main settings, display, then brightness. Turn off automatic brightness if its on. Now adjust the brightness, up, then down, then up(back and forth, but take your finger off the slider when you go up then down). now press ok to set the brightness. Go back into the brightness setting and repeat. Eventually(sometimes seconds, sometimes minutes) the screen goes completely black, like its off, but the device is completely awake. same as these 4.2 sods, phone calls and messages come in, notifications sound, etc. Only difference is the device screen is on when it goes black instead of it being off. The symptoms are the same. This behavior leads me to believe that it most likely isnt a kernel issue like many believe. I believe that its related to some coding that controls the screen. As we know, every rom/kernel has shown this behavior, even stock and unrooted(some more, some less). Personally, i had 3 of these sods last month(trinity kernel/rasbean rom), but i know that some users have them many times a day unfortunately. What could it mean that i can replicate this behavior on an awake device? Any more thoughts about this?
maybe someone using another kernel/rom can try to reproduce this?
I haven't tried your method yet. I'll and post my results here. I was able to replicate it using another program (check the links below)
But reading your post, I'm sure now that SOD has to do with autobrightness or brightness control (knowing that, maybe it is easy to solve?)

whre I answered to that phenomen. I was on RBJ + franco r348 that time
I can't reproduce (force) it now with RBJ + franco r360, I tried about 100 times.
Just wanted to post my results, maybe it's too early to tell as r360 is too young.
Why does this not happen on N4, N7 and N10
+ never had an SoD in this wee k (Running anarkia's stable berserk releases, only on 511 & 515 / Jellybro )

Maybe because OMAP is abandoned at 3.0.

Sometimes I have my screen say go off but I will click the lock button The screen don't come on but it is still responding. Meaning I can still unlock the device as vibration tells me if I click the ring or not. So this is all down to the SOD? WoW. Learn something new everyday. I am on Xenon-HD 11-12-12 but also had it on stock too. With me though to fix this it just required to to press the power button a few time then the screen returned. Honestly I don't find it annoying at all UNLESS I need to say make a call to my local emergency services. (999 in UK). That is the only time. My nexus S does the same too with the screen but only after I had the NAND chip replaced by Samsung. Hope you guys can find something and my bit of info helps a little.

if your device wakes, even after a few presses, its not sod.

we cannot pull out the battery and fix the SoD on those devices so how could we fix that on N4 & N7 ?

pressing and holding the power button for 10-20 seconds will force reboot those devices.
A battery pull isn't necessary; you can shut down the phone with a little practice (depending on your lockscreen).
1. Press the power button (or wait) to lock the phone
2. Press the power button again and unlock
3. [optional] Press the home button (center of screen near bottom edge)
4. Press and hold the power button until a short vibration is felt.
5. Touch the Power Off button (center of the screen just below a horizontal line from the midpoint of the volume rocker). This puts you in the Power Off confirmation dialog.
6. Touch the screen in the approximate location of the "OK" button. I start at the middle on the right side and work my way down. Soon I get the long vibration telling me the phone has powered off. This is the hardest to master since feedback isn't immediate; the long vibration happens several seconds after I successfully hit the OK button.
7. If nothing happens, press the power button to re-lock and start again.
8. Practice when the phone is functioning normally, and you'll be prepared for your next SOD.
My observations (bone stock GSM phone):
This happened once in a pitch-black room. The screen does not go perfectly dark, but it is extremely dim and uniformly grey. I could not make out any details, so the contrast is completely gone.
SOD happens all the time playing Ingress, or other apps where the screen is active for a long time. It seems to happen most often when the display partly dims before going to sleep. My phone is set to sleep at 30 seconds, and the "pre-dim" happens at about 25 seconds. That's usually where I get my SODs.
SOD happens to me less often with auto-brightness set to OFF. It's extremely rare in normal use (but happened just now as I replied to a text!)

wouldnt it be easier to just pull the battery? thank you for your observations btw.
simms22, I actually think it is a kernel issue. I only experience SOD problems when i use a custom kernel. Also yesterday I flashed stock 4.2.1 and tried for 10 min to replicate SOD using your method - I could not. Today I tried again - nothing.

My phone is in an Incipio case, and it's more of a pain to separate the case, especially if I'm in my car or out hiking or whatever. I've gotten pretty good at doing it blind. Also, years of running Windows have made me anal about doing orderly shutdowns. :laugh:
Forgot to add earlier: I was unable to replicate with the technique described in the OP. But as long as someone can get this to happen on demand, it ought to be solvable.
Edit: although I got the SOD in normal usage a few minutes after trying the technique in the OP. Maybe the display SODs on some specific number of brightness changes? That would explain it happening more often with autobrightness, also.

Just hold down the power button for several seconds. Continue to hold down the power button until the screen blinks off and the boot logo appears.
We are flooding here.. lets discusse this other place and leave the devs alone here
i dont know how replicate this 4.2 SOD, but there is a simple way to avoid it, put all animations inside developers option to 1.0
it doesnt happen anymore to me, stock rom and kernel (i have automatic brightess on if this can matter)
if i put all animations to off or to 0.5, when the screen time out and became black, sometimes it doesnt wake anymore..4.2 sod

When I was running the first few nightlies of CM10.1 it still did the "sod" on me. By default the animation settings are at 1.0. Not sure if it's different on stock.
I've had several sod's daily for last few day's and today finally flashed RBJ from the beginning plus dax's modified kernel and now i'm in watching phase. So far so good.
I have time without any sod... Maybe because I'm trying not to use auto brightness or because of the lastest versions of Francos kernel... Stock ROM

Hi, i have just got a new xda orbit and noticed that when the backlight goes off after a set period (30 secs), it seems to be still lit but only very slighty, so at night you still see the today screen etc. But if i press the power button then the display goes off. Is this correct ?
The reason im asking as i have been using an xda mini s for over a year and when the backlight times out the display is not visible at all in the dark. You have to press the power button to see the screen again.
Hope this makes sense
Yes, that is fine. The dim backlight will go out in time too.
MaskedMarauder is 100% right. It will go out eventually.
Ok thanks guys for the quick reply, just obsevered it last night and noticed it was different.
Thanks again...
I've tried posting about this before, but it never gets answered - i've got a mda III, and that dims to brightness 1 (from within the registry), but will never go out - regardless of what rom i've tried.
I've also noticed that i can force set it to 0 in the registry, but thats the overall screen brightness. None of the other reg keys (putting bkl1:, etc in the various power keys) seem to work.
Any one got any ideas or utils to sort this? I'd try to code this as there are some code samples which allow you to force this, but i've not got VS
Like you i've tried all the registry edits i can think off to no avail. I too have a wizard and find this irritating - plus backllight stays on when media player on etc.. No difference with wm6 so i guess it maybe a hardware issue. I use a small app to turn off display when apps are running and i want the display off.
I use backlight time of 30 secs and power of 1 minute - so overall similar to my wizards backlight time of 1 minute.
why not..
why not just pres the I/O button on the side to turn off the backlight when u don't want it on? obviosuly a bit of a hassle, but if u get into the habit of doing it, no problems
Because that puts the device into standby and turns everything else off too (except the phone etc.) So if your listening to music your plunged into silence.
I had an XDA2i (Alpine) previous to my Orbit and I actually prefer the dimmed screen.
A brief press on the 1/0 power button WILL make the device go into standby.... BUT...
press and HOLD the power button for LONGER than 2-3 seconds and it toggles the backlight on and off, whilst STILL keeping the device on!
hope this helps

While your screen is off. There is a process running in the background. It could be anything.
It's when you get alike, a call or text, and your screen comes on, and stays on, even if you have screen-on time set to go off after x amount of minutes
oh yea i def have this sometimes.

I thought it was the issue where the phone doesn't like to wake from a lock state. I know when i was running CM7.0 rc1 and the screen would lock and turn off, when I hit the power key, the screen wouldn't come back on. I usually had to press the power button then tap the screen to get it to turn on. Sometimes i had to just fight with the power button a few times to get anything to show. It was quite annoying. Might have been a kernal issue, not really sure as I updated to CM7.1 and a new kernal all at once.

It could be, or maybe we're both right
I have recently encountered a problem with my hox, where, if I press the power button, the screen doesn't awake. It's a little weird, because the back home app switcher buttons do light up if it is dark enough around me and, after pushing them a few times, the volume buttons respond as well.
I haven't fully tested it, but it seems like when I wait like a minute or so, maybe more, the screen does finally wake up. I have also held the power button several times to restart it while it was like this and then the screen doesn't light up until the sim unlock screen pops up.
I have yet to factory reset the phone etc., but I was wondering if anyone else had run into this problem. I have looked around the internet, but was unsure what to search for.

Are u using sweep to wake?, that sometimes causes this problem
Sent from my HTC One X using Tapatalk 2
Nope, I do not have sweep to wake.
Well, after a while of being okay, the issue is showing up again. If I press the power button it does wake the phone somehow (back, home, tasks lights light up, volume can be altered), but the screen wont come on. And when it's one of those rare moments that it does turn on the UI flies everywhere, making it literary uncontrolable, until at some point the screen just turns itself off.
I am not running any custom things, everything is stock. I tried a factory reset without erasing the SD storage. I also have just sent an email to HTC, but it being weekend and all I still have to wait a day or two.
Any other things I could try?

Hi, I was wondering what did you do regarding the lockscreen problem. I'm having exactly the same problem here. I've already done a factory reset but it did not solve the issue. From time to time I'm not able to unlock the phone.
Please HELP!!!
It sometimes happens to me, recently after clearing the clock and weather apps and widgets. I don't know what it is.
In Android 4.1--pretty much every iteration of it, including CM10--when I hit my power button to sleep the phone, the phone would go to sleep immediately. In 4.2 and beyond, there is a half-second delay when I push the power button and when the screen actually turns off.
This issue is present in 4.2 stock, 4.2.1 stock, 4.2.2 stock, 4.3 stock and every single version and nightly of both CM10.1 and CM10.2 that I've flashed. Disabling the CRT animation or changing the animation scale does not fix the issue; the device still hangs for a half second or so before turning off the screen.
This persists no matter what I do. The usual suggestions do not work; the problem persists. It's going to drive me nuts eventually, because I keep thinking it didn't take, mashing the power button a second time, only to turn my screen back on again.

Hello.
Add the "go to sleep" control on the notification drawer's power widget (Settings->Interface->Notification Drawer) and try it. If works, problem solved. If not, we can discar hardware (power button) issue.
I've never encountered the issue in everyday use. It has happened to me a handful of times, but only when the phone is heavily bogged down. Never under normal use. I assume you would know if your phone was being bogged down though?

I just did a reboot of my tab and it got stuck at what I call "Black Sceen Crash".
Looks like being switched off - but isn't.
It does react on screen touches with a very brief vibration.
And it gets a litte warm.
Does not react on long pressing power button - so no reboot, no download mode, whatsoever.
Guess I have to let it run out of battery - which might take couple of days with screen off. We'll see.
Any idea what to do or what could have caused that behavior? Any similar experience?
Before trying to reboot there was no mobile connection, and I wanted to reboot to get it reconnected. Otherwise no problem.
I am running stock Samsung ROM, rooted, Skyhigh Kernel, OC/UV.

Yeah, I also discovered long pressing power button alone does not force-reset the device. I managed to reset it though by press-hold Power + Home + Either Vol Up/Down. Give that a try.
I can't remember whether it was the Vol Up or Down, try one then the other if it didn't work first time. Good luck.
After a while (30 min probably) it did not any more react on screen touches and was cold. Off maybe? Still no reaction on long pressed Power Button. Tried Volume Down+Home+Power Button - and fortunately it revived the tablet. Strange. Thanks for the hint!
I face the Black screen of death and the device (T805) was not responding to any reboot, recovery or download mode actions, sent it back to Samsung support and they claim an internal piece of HW need to be replaced, I refused that and asked for refund or new device... After a week I got a replacement device...
