Does anybody know if backlight is LED or CCF? I am planing on leaving Streak's screen permanently ON (low brightness) overnight as an alarm clock, and that would eventually kill CCF lamp, but should be OK for LED.
Thanks!
Hey up. the clock app in 2.2 has a brightness button that seems to turn the backlight off, and its a pretty nice screen too. should be ok.
You have to leave the screen on to use it as an alarm clock?
Yes
Yes, I would prefer to see the time when I wake up (sometimes) in the middle of the night. LEDs have practically unlimited life, usually 50-100K hours, but cold cathode fluorescent lamps loose brightness with time.
I'm sure no modern phone uses a cold cathode.

Why does it randomly stop working? Or, right before the screen shuts off, insted of dimming, it brightens? I can be in total darkness and if i close an app, it goes to 100%.
I experience that as well. It's quite annoying.

I've found that it simply doesn't work
The auto brightness sucks. When it's in a completely dark room, its too bright. When it's in direct sunlight, it's not as bright as it COULD be. Annoying.
I wish we had the brightness notification slider like the vibrant but till that comes out I have been using the power control widget works fine for me.

Part of this may have to do with "Power Saving Mode" under Sounds & Display..
It says it analyzes the image on the screen and adjusts the backlight to save power.
I've noticed when I'm on a screen that's majority white pixels, the display will dim regardless of the light in the room.

I agree with that theory.
I've noticed that my Fascinate's screen dims before going dark. Is there any way to disable this behavior? I use keep phone overnight in a desk dock, running the app 'Bedside' to display an extremely dim clock. The phone's automatic 'dimming' actually seems to brighten black portion of the screen a tiny amount.
I've messed around with the display settings, but thusfar had no success. Does anyone know of a workaround?
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).
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.
The always on display screen is just way too dark and I'm outside in the sunlight. I can't read it at all. Everything else is fine, normal phone screen brightness is just right. Is there a way to adjust brightness of the AOD display at all?

I just recently turned mine off because of this. If I leave my phone face down it is too dark when I pull it up to see the time etc. If I left it screen up it would be at a very high brightness. It just adjusts to the situation slowly.
Thanks....I actually didn't see any response from the AOD to get brighter in sunlight...maybe I didn't wait long enough, but I waited a lot longer than I thought I should need to. Are you sure the AOD screen has any reaction at all to ambient lighting?
Yes it does effect it if it's on. Just put a finger over the sensor and it will dim
