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

This is something I've had pretty much since day one from what I can remember. Basically, sometimes the screen won't come on but the buttons light up. I press the power button again to 'lock' the screen, give the screen a hardish smack and then press power as normal to wake the screen and it comes on fine.
Is this SD card related or something else?
No suggestions??
I had it a while ago, where the SetCPU was set on smartass and minimum frequency to 128 MHz. Sometimes it did not turn on. Other than that, no idea.
Don't use SetCPU or anything like that, does it when stock as well...got a new SD card on order so will give that a go
hi, as described, it happens to me... annoying a resolve this with spare parts by enabling "animation windows" from off to all
hope this help
i have the same problem...i can't even reboot when it happens, have to take the battery out
I fixed this by rebooting or flashing the rom again.

Good Morning all...
I've been running different builds of Android on my Kaiser since around October of 2010 and have yet to run into this one.
After initial boot and the screen blanks after 1 minute (what I have it set to do), if I try and press power (or "end"), the phone wakes to a blank screen.
I have not run into this problem on my spare phone yet but my assumptions are that the OpenGL driver is not being set correctly after wake-up. If I keep the screen on, everything is fine. Once the phone sleeps, it won't wake up. It does react as if the screen works because the phone will vibrate after holding power or end for a second or two. I can even get the phone to shut down, remembering where to press to shut it down, all with a blank screen.
Thoughts, theories, etc.?
Mods, please delete this thread. I have just about given up on any hope of a decent kernel for these phones.
Thank you.
This is doing my head in! I have the very same issue noted in this thread http://forum.xda-developers.com/showthread.php?t=901998.
A lot of the times I press the power button to wake the device it will show the unlock slider for a very brief second then the screen goes black (not off, it is on but black). Other times, when I press the power button to wake the screen will turn on and off a second after that. This leads to a very frustrating series of button presses until I can actually unlock the phone.
I tried setting the screen timeout delay to immediate as suggested in the other thread but that did nothing.
FWIW SetCPU will lock the processor between 125 and 245MHz when the screen is off, using a scaling of Powersave.
Any help?
Set the minimum frequency to 245MHz.
I have experienced severeal problems getting out of standby when having 128MHz as minimum. Plus, You don't really save anything on going to 128MHz.
That pretty much did it. Thanks.

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.

it does. just not as often/widespread as with the gnex. ive seen enough reported with the n7 and n4(i havent read any reports with the n10 though).

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
