Hi everyone,
I have a Nook Color running CM7.1 off sd card. It was working nicely for 3 months, however, there's something weird happened to me today.
Normally, I use the app "Brightness Level" to change the screen brightness and it worked fine. But it doesn't work anymore. What's worse, apps like the Kindle and the Nook reader, which have the ability to change the brightness, can't change the brightness anymore. The only way that I can change the brightness is go to setting-display-brightness.
But I notice if I use brightness level to change the brightness, it will take effect after waking up the screen the next time.
I have reflash the rom and also tried to fix the permission using rom manager, but no luck.
I will appreciate any help that you guys offer.
Thanks
Richard

Hey guys I'm having some concerns about my xperia play and so i want to know if i should be worried...
My screen flickers. ( Not on/off) but between shades. It's hard to explain but it drops between levels of brightness, but here's the deal i turn auto brightness off and it still flickers. Now i have noticed that the screen will dim ( flicker shades) with the orientation of the phone. Idk.
Also when I'm downloading the games thru xperia app it takes forever, i have high speed internet and I'm connected via WiFi but should i be expecting A 150MB download to take up to 45 minutes. Seems kinda slow to me.
Thanks in advance guys.
By Tue screen flickering if u mean the auto brightness increasing and decreasing immensely at times its normal since u cant turn off the auto brightness in our phone....
About the games..most of the games took 15-20 mins or less for me on an 8 mpbs connection

Is there some kind of other brightness settings, i turned auto brightness off. And I'm still getting fluctuations in the shade of color.
if you have root you can disable this, but it is only temporary as somewhere in the system it re-enables this.
create a gscript with su ability
start script below
echo "0" > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/enable
end script above
do not include the start and end parts
lasts around an hour, stops the flicker in bad light situations

It wont turn off even if you untick it, its an anoying bug, hopefully custom roms/kernels will solve this, dont worry about the downloads, even with high speed internet, keep in mind most of the developers are small companies and cant afford expensive hosting, even the gameloft servers are slow imo

You can NOT turn auto brightness off on the Play, it is hard wired right into the os, even if you used an app or widget saying it if off it is NOT! there is nothing you can do until SE fix it or some members here mod the os,
All the Play's do exactly what your describing, lots of topic here and elsewhere about it, everybody moans about it!
And regarding downloads, things from the market download fast for me, very fast, but other stuff from other places can be very slow, gameloft for example, takes hours! just depends on the servers your downloading from.
Hey thanks guys for the information. When i get to a desktop I'll hit the thanks button for all of you. I think my WiFi was acting up last night, i was playing some zombies and downloading torrents at the same time.lol. anyways thanks guys again.

Actually you can disable it, its just not permanent please see my previous post
To be honest with you I like the auto brightness. I think is super responsive which other phones it seems like it takes forever to kick in which is why I normally shut it off

I think it works great too, but it is nice to have this little gscript ready for times when the autobrightness goes wacky and the screen flickers
My backlight keeps adjusting itself. Even with auto brightness off.
I don't really want to call it flicker, because it doesn't seem like flickering. It's more like pulsing slightly brighter and then slightly dimmer. It's most noticeable on light colored backgrounds, like the browser or the play store. As I said, I have auto brightness turned off, so I would think that there'd be absolutely no change in brightness when bringing up a bright window.
Any ideas on what can be done to fix this? I am rooted, but I have not installed any custom roms. I'm running stock 4.2.1.
Thanks
Its a well known bug with jellybean

Any fix? If necessary, I'm willing to load a custom ROM and/or Kernel. I just haven't gotten around to it yet.

If you're rooted there is a solution here....
http://forum.xda-developers.com/showthread.php?t=1815414
The essence of which is as follows...
Run this command using terminal emulator (https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en)...
To Disable SmartDimmer ...(to prevent 'flicker').
Code:
su
echo "0" > /sys/devices/tegradc.0/smartdimmer/enable
You can set this up as a script to be executed at boot using ScriptManager (https://play.google.com/store/apps/details?id=os.tools.scriptmanager).
Set it as ROOT and BOOT... you won't need the 'su' command in the script, as ScriptManager will already be granted su permissions.
This has totally eradicated the screen brightness fluctuations (not as pithy as 'flicker' but I think a more accurate description) for me .
Rgrds,
Ged.
Thanks so much! I did this and the flickering went away. I even undid it to make sure. When I shut it off, the flickering returned. Turn it on, flickering gone. I even checked at different brightness, and no flickering. Originally I thought this was just another defective unit. After spending a bit of time looking around the web, turns out it is a common problem. I am glad that there's a simple solution, at least for us rooted folks.
And I agree that flicker isn't exactly right. To me, flicker is more random. This is more of a rhythmic pulsing of the backlight, between brighter and dimmer. And I can readily reproduce it by shutting down chrome and going back in.
Good afternoon I have a question regarding my nexus 4.
It is realized that the stock times the brightness of the screen is lower, as if on automatic but it is not always leave at 100% brightness ... I have to reset the machine back to normal ... Even moving in brightness, auto etc putting it happens when it does not work, seems to be without action, does anyone know if it can be a problem? I have installed Go launcher EX not know if it's some setting or a problem that I hope will help me.
It's like that.

Hi guys, we all know after experiencing some time on custom roms we once in while return back to the stock rom because of better stability. The one thing that has been continuously annoying me in the stock rom from the day first is that it's minimum brightness is not that minimum compared to other phones. It still is way too bright to be used in dark.
I used RR rom few days back and it had that nifty color option which i used to reduce the brightness.
Is there a way to do the same in stock rom. I am not talking about blue filter or other such programs. They are all screen filters and instead of saving the battery they drain it more. I am talking about the LCD brightness.
Thanks

I use display brightness https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&hl=en that does an overlay (which some apps don't like). You can set the brightness to -90% I think. It does have ad permissions and does want internet access but I just add it to my firewall to block those permissions.
I often have to be very persistent in training the phone for brightness in the auto mode. Especially in the evening, when the brightness slider is to the left of the middle. I set the desired brightness, but it is not fixed. You have to do it 10 times or more, and after a minute the brightness again lives its own life. Has anyone come across this on customs ROMs? Everything was great on stock.

Maybe you don't know auto-brightness can be trained due to users preferences. At least it works on stock.
Or don't you use auto-brightness at all?
I am accustomed to auto-brightness at any time of a day and I like to use it. I don't want to change it mannualy after each changes of circumstances.
However on the custom ROM the process isn't so easy. I just have doubts if it will be successful at all.

There is nothing special to say more here. Just in the auto-brightness mode, the user sets the slider to the desired level at any time. This is repeated a certain number of times and after that the phone remembers the new settings and, depending on this, the new auto-brightness algorithm works. The learning process for brightness is endless. You can adjust it anytime to your preference. In any case, it worked fine on stock and the phone memorized new settings very quickly.

oh! its a cool thing. Thanks
I tried A11, A12, A13 ROMs, and after that I'm on A10 stock again. I think that's the best way for me to keep my nerve sells. Now the autobrigness doesn't even need additional training.
