After I install almost any rom, the screen no longer turns off normally. Theres always a little flash before the display shuts off. At first I thought it was linked to the crt animation, however even when I disable crt and disable the animations from the developers settings, the flash always stays. I believe there was a rom that i installed that didnt have this problem, and im pretty sure that one didnt have a crt animation setting. But I can't really find that rom or any rom without crt animation anymore to test with.
Theres a link to a video where I try to show this. Its hard to actually capture since its all very fast, and Im not too good with cameras. But you could still see it.
The first time is turning it on and off with the default rom that came with the phone -- Display turns off normally, no flash before turning off.
The second is with CM10.2 right after installation -- There is a flash before the screen shuts off, but its hard to see with the crt animation.
The third is also with CM10.2 with crt and animations off -- There is still a flash before the screen turns off (seen best in the 2nd to last instance)
The flash mostly comes from the upper right corner area if that helps.
Its hard to see on video because of the changing in lighting from turning the phone on and off, but its very noticable in person.
How can i fix this, or is this a condition on all phones?
Edit: You can see it a lot better in this video after i turned it off and on with a black background

first i thought it was launcher pro's fault, but after changing launcher and rom release i'm pretty sure it's something else i haven't tracked down yet.
just after a reboot phone works as usual: screen lock runs after 30 seconds or by clicking the power button
after a while (days or even hours sometimes), the screen lock does not kick-in anymore: the screen just turns off and when you press the power button the phone is already unlocked.
i noticed that when the phone is in this "lock-bug" mode the notification led constantly shows a faint red light (you can barely notice it in the dark because it's really faint).
tested with:
launcher pro
go launcher
factory rom 2.21
blurless 2.34
I used to have the faint red light on after flashing a new rom.
It disapeared after I changed display setting to not automatic brightness.
It seems that the faint red light is the light sensor.
But I know nothing about your screen lock problem.
I have run into the same thing. I have not yet noticed the light, but I've had the screen lock stop working on my phone twice (I bought 3 phones 5 days ago for work). Like you, a simple reboot fixed the problem. I also tried toggling screen lock in the settings, and setting up a lock code, to see if the screen lock would start up. Both of my times, the first I noticed the issue was when I received a phone call and didn't have to swipe to answer, but that could have just been coincidence.
It isn't really a big deal for me or the employees, but it is a nuisance.
Happened to me as well, twice. First time it was just annoying that I had to reboot, second time it drained the s**t out of my battery in three hours.
So it's a bug allright.

same here.. it just stops working.. any fixes yet?
I just installed CM7 stable version yesterday, everything goes smoothly except for the autobrightness function. Whenever I turn my screen on, the first time it always very dark, although perceivable but it's like the autobrightness is broken. Yet, when I immediately turn off the screen and turn on again, it's bright like nothing happens.

try turning off "screen off animation" it will fix it. it a known bug.
please refer to this thread Numerical explanation of the CM7 automatic backlight settings
Byrong does a really good job explaining what the auto brightness settings does in CM7.
By default CM7 auto brightness doesn't work very well, you need to configure it to your liking using the options described in that thread.
Use the status switch toggle the autobrightness!
This is the second time on 2 different roms that somehow my phone has been stuck with a black screen and when unlocked the screen stays off. Its a bit hard to explain but pressing power lets the screen to come on for just a second but then it goes off...yet on the black screen you can slide it unlocked (screen stays off) A reboot goes back to the same issue. after many button combos the screen will finally stay lit. The only way I have found to cure it is to uninstall lightflow. (Im really not sure thats what is causing it) If you dont change anything when you lock it your right back into the black screen thing..... Anyone seen this using lightflow or not??
I've had this problem to. I had it when I was using the phone on stock without lightflow, as well as using it with HD revolution and light flow. I have no idea why its doing this though?
I had this problem when I used the app "Wave Launcher". I found the most effective way to keep the screen on is to call the phone, stay in the call, and uninstall the app..

Are you running the 350 mhz idle mod or UVing? Seems like your phone isn't getting enough juice.
I emailed the dev's a few days ago. They came back with the response to uncheck "s6e8aa0 control", which I believe is disabling access to the main screen. I haven't seen the sleep of death since. He also said to look for a future update which removes this option.
Hope that this was a helpful first post!

I have the same problem today! When light flow is active the screen goes on for a second and then stays black.
Sadly I can't find "s6e8aa0 control" in the newest version. Can anyone help?
Got it working. I should use the correct settings^^
But the program is not working how I would like it :/
When you push the power button and see that your screen is inverted, then.... with the screen still on, hold your phone tight and give it a hard flick of the wrist. This has worked twice for me.
Running Calkulin's 2.6, Overstew's ICS AIO, Launcher Pro
Is this working for anyone running different setups?
can anyone verify that I wasn't drunk when I wrote this? The wife says I didn' t do anything today but get ripped. I told her I helped a lot people...just not her.
I have had the screen invert once... I just rebooted...
I have also had my entire screen go magenta for some strange reason...
The screen "appears" to be inverted... but it isnt... at least not to the phone. unlock the screen with the same manner you always would even though the visual cues are wrong. What ever lockscreen you are on, just do the same motion again. then once in the normal home screen, rotate it around a few times and it corrects itself.
I know exactly what you are saying about being inverted but still fully functional....giving a shake a shake with the snap of the wrist solved the issue without playing games.
Download Spare Parts from the market and set "Window Animations" to "Fast." Haven't had the screen inversion problem since.
i had it one time and and using adw pro all i need to do is rotate my screen and it resets the orientation
Ok, this is VERY irritating!!! I set my phone on my wireless charger before going to bed last night, woke up this morning and my phone screen has turned to Greyscale. Battery is at 100%.
1st things 1st - My phone is not in Power Saving Mode, nor is it in Ultra Power Saving Mode. Also...... I have already gone to Settings-->Accessibility-->Direct Access-->Greyscale (off).
I have tried toggling all of the above settings (I also have never ever used any power saving/greyscale mode to begin with). I have even tried switching themes, even reverting back to the default original theme that came with the S6. Nothing seems to work.
If I power off or reboot my phone, the boot screen is in color as well as my phone briefly is in color again while android is initiating the phone. After about 40 seconds, the phone turns to Greyscale again.
Has anyone else experienced this or have any other suggestions for me to try?
I am using a stock T-Mobile unrooted phone.
Ok, fixed! There is another "Greyscale" option under Accessibility for Vision, I turned Greyscale off. puzzled as to how that got switched on by itself but at least I know now.
Yes! The accessibility worked for me as well. I had to go to settings-->vision--> color adjustment. Then I had to drag colors in order from like this blue to brown to pink to purple. Thank you for suggesting vision! I was so irritated of the grayscale screen!!! I am guessing that it probably did that due to me ALWAYS going in and out of ultra battery saving mode (just my hypothesis--I might be wrong).
