Lockscreen Flicker - Android Software Development

I have a pretty annoying thing with my lockscreen.
Whenever I lock or unlock the screen flickers. Something like screen brightness goes to max and after that to min.
I tried WidgetLocker and I have the same issue.
Using i7500 with latest GAOSP 2.2.1.
Any ideas/sugestions would be appreciated. Thank you !

Do you have the auto-adjusting screen brightness option selected?

Don't know what that is but I have auto-brightness ON.
It doesn't make any difference with auto-brightness ON or OFF.

Any ideas?

Auto brightness only brightens, never dims

I noticed that the brightness only brightens but never dims back in automatic brightness display setting. I can reproduce this easy with turning the lamp on my desk on and off. It only goes back to the lower brightness if turning the screen off and on again.
Noticed this too but seems to only occur when I use a widget to toggle between Auto and 100%.
If I leave the setting in Auto from within settings then it seems to work. Brightness widgets seem to break the auto functionality.
Hmm, I don't use a brightness widget. The light of the softbuttons go on if I cover the light sensor, but the screens stays in high brightness.

Must be an all around bug then. If you turn the Atrix off and back on then the auto brightness functionality is restored.

This must be an Android thing. My Atrix does the same thing, as did the Nexus One I had before. I've had several (high end) Nokia's that dimmed/brightened perfectly. After 5 seconds, they would brighten (or dim) accordingly. I was hoping Motorola was better at making phones than HTC (the KING of bad battery life). We ALL lose here. Our precious battery life is being drained by the poor execution of a simple function.
This is a stock android thing (problem). Custom ROMs can allow it to dim and change brightness smoothly rather than in discrete steps (Cyanogen).
That's what I thought. I found this free app called "esdimmer". It supposed to be for Galaxy phones, but it's somewhat working on my Atrix. Does this function work any better in Gingerbread?

Well it's good to hear that it's a stock android problem and not the actual phone. I did find a way to get around this problem but it's very limited. You can get the screen to dim by first putting the phone into standby and then press the standby button once again (which gets you into the lock screen). You'll notice that the screen then dims (if coming from a well lit area/room to a darker one).

Screen dims when it shouldn't

I have set my S4 up so that it runs at 100% display illumination when charging. No autobrightness.
What is bothering me know is that the screen dims to about 50% very quickly after I stop touching the display and jumps up to 100% while I touch it.
Toggling smart stay doesn't change anything. Smart stay on doesn't help even when I look at the display (though it should just prevent it from going off .. not from dimming if I understand correctly.
I would like to display to stay at 100% when charging .. or at least set dimming to "after 15 secs" or so.
What needs to be done?

I was reading about that and i found something about the chipset SnapDragon has an inside feature to adjust the screen brightness independently of the software (firmware on this case). Maybe you are watching that effect..

There is a small tool that fixes it: "Caffeine" .. obviously
Intelliscreen also does the trick .. and there is a timeout you can set (not sure if it messes up the timeout for regular use when not charging though).

Is not the solution because caffeine prevents from time up screen brightness but it doesn't prevent from cpu feature. Even if the screen is always wake up and the autobrightness is off, the brightness will be changed because the chipset.

Could this be related to heat? With the screen on and charging + what ever other task you have the S4 doing it may be the S600 is governing the screen to reduce heat... just a theory like.
I'm having the same problem too.
If i unlock the phone the screens dims to about minimum brightness.
I can touch the brightness bar to make it brighter and it stays that way for as long as i don't lock the phone
If i lock the phone and unlock it again the screen dims again?
Tried all different settings bur nothing helps...
Very annoying....
Yesterday i bought and installed lightflow to control my led indicator.
Just a minute ago i removed the app and voila! No more screen dimming!
Damn, really love that app but rather no led control than having my screen dimmed to the lowest possible brightness.

Alliance rom screen dimming issue

Running the Alliance rom, clean install on stock slot. No other major issues that I can think of. I've got it set to maximum brightness, not on auto dimmer. When the screen dims after 30 seconds or so, when its about to turn off due to inactivity, half the time when I tap the screen, it recovers to full brightness. The other half the time, it gets a little brighter than the dim mode, but not much. It stays way dimmer than the full brightness setting that I keep it on. I have to pull the notification bar down, slide the dimmer down, and back up to maximum, and I'm good to go until the next time it does it. Which could be in 30 seconds when it dims again.
Anybody else having this issue?

I have the same thing happening. Personally I have been too lazy about it to check through settings to see if I've done something. I'll check on it and see if I can find a fix.
*Update*
I've checked through all my settings and can find nothing that might cause it. I don't have Auto Brightness set, nor do I have Auto Adjust Screen Tone turned on. I saw nothing in the Alliance Settings either. I believe it is a system setting that is probably buried in code somewhere (far beyond my knowledge).
**Update** I reported the bug in the Alliance Forum.
I tend to agree. I've looked through settings, etc. just as you have, to no avail. I'm nearly certain it's done it since install, so I don't think it's something that I've changed. But I could be wrong. I've also tried it with auto adjust turned on, does the same thing. Auto adjusts to a dimmer setting sometimes

Screen keeps dimming

I had to switch out my s7e and my 2nd unit keeps dimming the screen when in low light. I have brightness at max and auto brightness turned off. Are there any fixes for this? Does anyone know if the Base (sp) rom fixes this?
Test if your device does this: set screen to max brightness and turn auto brightness off. turn your screen off. Turn off the light in your room. Turn screen on and unlock screen. It should be a bit dimmer. Now turn screen off, turn the rooms light back on, and turn the phone back on. It should now be brighter. Does your phone do this?
Bump
Mine does it too and while this issue has been documented on different forums I have yet to see a real season or fix. Found posts about it also happening on the S6. It is irritating as I thought that auto brightness turned off should completely prevent this. You can trigger changes by covering/uncovering the proximity sensors at the front top of the phone with your fingers.

Slow wake-up

Hello friends,
I have noticed that when Adaptative brightness is on, my phone take a few more seconds to wake-up from its screen off, sleeping state.
There is really a noticeable difference than when Adaptative brightness is not enabled. I'm wondering if anyone else had noticed this, and if there any way to fix it.
Regards.
Thanks this was exactly my problem with Android N final release. As soon as I turned off adaptive brightness my screen wakes up right away. Did you ever find a fix?
