Why, hello there!
With the Cali sun rendering my Droid almost impossible to browse I come to XDA to seek advice on possible solutions to make the ability to see the screen even marginally better! (Bar a anti-glare shield) Heard there are some possible tweaks on brightening the screen beyond it's apparent '100%' brightness but am curious if this is just positive thinking?
I have been hunting on forums for tips and tricks but to no feasible avail and, 'go in the shade' falls short of answering my question!
So is there any new developments on this or is it not possible to brighten the screen to browse on a sunny day?
Much appreciated!

Are you rooted? If so go to the Market and download Adjbrightness app, it is free and lets you turn the screen display brightness to its Max or any other preset or custom brightness you like. You can also turn off the backlight on the touch keys. If you aren't rooted try auto setting in the display options or try an on screen widget such as the power bar widget that is stock loaded on the Droid1. Long press the homescreen, choose widget, powerbar. Hope this helped.
Thank you for Your reply!
I don't think I worded my question properly.. I meant brightening the screen beyond using an app that can adjust the brightness (I have mine set to 100% in the sun and 0% at night!)
I was hoping there was a further tweak to get the screen even brighter to browse when the sun is glarong down...if that is even possible?
Thank you so much!
.......Ohh and yes I'm rooted (LithiumMod)

Is there a way to lower the brightness beyond the default minimal setting? I've noticed that even on the lowest setting, I can still use the thing like a flashlight.

Too bright? Haven't heard that one. Mainly complaints about not bright enough in the sunlight and such.
I'm no programmer or anything, but as far as I know the android system has a brightness value of 0-100%, and the user (or apps) can change the value to anywhere in between. There might be a hack to undervolt the screen, but as far as I know one doesn't exist.
I'm guessing he has an AMOLED... in which case, I understand. The screen is bloody bright, even on the lowest setting.
My only idea would be to install one of the CM roms that lets you use the surface flinger mod to change your display to a monochrome red.
download 'screen filter' or 'total screen control' from the market. they allow you to apply a dark layer dim your phones screen to however much you want. hope this helps
Only time I really notice mine is too bright is reading if I use white on black, so I use a grey on black.. Fixed.
Although yeah, if i poke into the market first thing in the morning or such, it's pretty bright.
Problem with the screen overlays with surface flinger and such is you have to manually enable/disable them. It would be nice if the screen would go lower in some cases.
It's a great app that dims the screen and make it easier for the eyes, but I found one major bug today. While the filter is on, you wouldn't be able to install any apk's. The button is there, but you can't click it, you can only cancel. Basically it feels like your touchscreen has a dead spot right on the button.
Anyways I was panicking thinking my nexus 7 went crazy, and I uninstalled a lot of apps just to find the culprit. So this is just hoping no one else panic like I did. I also already emailed the developer.
1. It was discussed before, use search.
2. Stop using that crappy app and use https://play.google.com/store/apps/details?id=mobi.omegacentauri.ScreenDim.Full for reading.

Um, I use that app, but it doesn't dim it lower than the system does. I just use it to quickly adjust the brightness instead of going into the settings.
EDIT: Yeah, I'm an idiot. That's not the same app I use. Just looks very, very similar. None the less, I tried the free version and it did not get noticeably dimmer.
I'm using the app '2x battery' which also has a screen filter feature, no problems in use, also seeing as I paid up for it it allows to filter by colours, so have set it to fade in a purply filter which basically reduces the green tinge my screen has, took some fiddling to get nice result but got double whammy of screen a little dimmer for indoor use and better colour balance, no lag or Faff so far.
Free version just allows a standard dimmer fine for most scenarios

Well I think screen filter is simple and it e works very well. I'm going to continue to use it, just have to turn it off if I'm installing apk's
I use 'Night Mode'

I am using screen filter with Sony bravia engine and it all works great. screen filter still gets blurry at lower dimness though.
Try Root dim or Voodoo display filter. Both are great for the purpose.

This thread I'm only taking about the specific app named "screen filter" though, just so people won't get confused. It works great btw, the screen can get as dim as you want.

The app you want to use is Custom Auto Brightness by Dmitry Matuzko. It lets you set brightness levels based on your light sensor and has the option to use screen brightnesses lower than the programmed limit without using overlays. Obviously you won't be able to go lower than the hardwares limit, but in most cases the manufacturer sets the software limit much higher than the hardware limit.
Onibabar UpdateUpdate
Thanks for posting this thread! I don't even use a "screen filtering" app BUT I was having the same issue were my INSTALL BUTTON was no longer working, and because of this thread I now knew at what sort of 3rd party apps to start looking at. At first I thought it was the ROM I was on, then I thought it was only on 4.2.2 ROMs since it happened on more then one of my setups, and finally, I thought it was a Mod I always use, that gives my phone inverted apps. In the end though, it turned out to be the latest update to the Onibabar app from the Play Store. Its a app that places a battery bar on your screen and the latest update allows it to be positioned going down on either the right or left side of the screen, in addition to the top or bottom. So whenever its set to go on the left or right side, it disables the INSTALL BUTTON when attempting to install an app from a file explorer...

I have use the search button to see how i can lower screen brightness on galaxy note.
i found everywhere mentioning screen filter, it is not i don't like screen filter, but when i take screenshot it will be tinted gray.
so i decide to go to a more elegant way like what atrix 4g user did.
http://forum.xda-developers.com/showthread.php?t=1245332
i tried with my note, i cant find sys/bus/i2c/drivers/lm3532, i decided to check folder with the nearest name, but i can't find it.
so i decided to download linux, mind you i have no idea how to use linux.
i downloaded samsung ics opensource update 4, inside i can't find leds-lm3532.c,leds-lm3532.h,board-mot-lights.c.
so futhur dig found leds-lm3530c, the file structure is different with leds-lm3532.c, but i think it works the same.
any good suggestion from experts?

I decided to check what AdjBrightness do.
it is modifying the following files
/sys/class/leds/lcd-backlight/brightness
/sys/class/leds/amber/blink
/sys/class/leds/amber/brightness
/sys/class/leds/green/blink
/sys/class/leds/green/brightness
all return errors in note.
further investigation leads to Rootdim:

/sys/class/leds/leds-sec/mmc1::/brightness
/sys/class/leds/leds-sec/mmc2::/trigger
/sys/class/leds/leds-sec/mmc2::/brightness
here all the triggers return error.
next thing i check /sys/class/
i see backlight/panel in it.
i also see lcd, leds and lightsensor.
have no idea, keep digging.

Found s6*aa*.c files inside driver folder.
There will be some info about 5.3inch screen.

From 0,1 to 30 is 0
Conclusion minimum brightness for galaxy note is 1(more than 30)
Keep digging.

the whole thing means samsung have tried other lcd before hd super amoled 5.3 inch?
keep digging for the brightness

End of research, the brightness for amoled devices only have 24 levels.
lower than that you will need to adjust contrast for better battery consumption.
if you use filter it wont decrease battery consumption, and it will affect your screenshot images clarity.

So, what's the verdict? Are we stuck with "too bright in the dark" screens on our Note's?

For that purpose a screen filter works just fine for me.
Frankly it's not doing it for me, it looks like I'm looking through a grey plastic bag.

So what is conclusion bro?
We can't use brightness below the SYSTEM-MINIMUM?
I also want more battery by reducing brightness to below 10.
AND yes you did well.
Good research.
Hi, I love my Xperia T but there is one thing that bothers me. I noticed that every xperia T has that automatic screen dimming when viewing darker media on your screen. For example, when i turn on facebook app, before the actual app opens there is dark grey screen. During that sequence screen gets darker, and when white facebook page pops up you can actually see screen adjusting its brightness to higher "normal" level. That really bothers me especially when gaming. On dark sequences screen gets really dark, and than it takes second or two to adjust normal brightness when brighter sequences appear. You can actually see brightness going down when darker images are displayed, and then back up again when brighter images appear.
So I'm not talking about dimming when overheating or flickering (that second is fixed by jellybean update as I noticed), or etc. And before you ask me I if turned on autobrightness in display settings, it has nothing to do with that.
My question is, is there a way to turn this off because it is really annoying?

Can you read my last sentence before question, please? It has apsolutely nothing to do with that. "Adopt to light conditions" means adopt to light conditions in your sourrounding, not in your screen light conditions.

All i thought it differs to auto brightness thats why i ask it sir. Sorry for the question then
You dont have to apologise. So, the problem is that when you watch darker images, or videos, or just any darker screen on your display, contrast and brightness goes down. And when you switch to brighter screen you can actually see, with your naked eye, brightnes going up. I see that Sony intentionally put that feature, but it is very, very stupid one. There is no point in making dark images even darker with even less contrast. I assume they wanted to achieve better black levels that way, or I don't know, but it is very stupid way of doing black levels more black. And, of course, there is no setting in settings menu tu turn this nonsense off, nice one Sony!

This similar annoying ass feature is there in my Spectre laptop. This was supposed to be a battery saving feature and I haven't yet found a way to turn it off. Maybe it's also a way to get higher black levels.
This is the Bravia Engine. Just unselect Settings -> Display -> Mobile Bravia Engine

Dude, this is definitely not a battery saving mode. There is no need for batery saving mode when displaying dark screen, and the problem occurs when displaying dark images or any other dark media, app or non-app. every single time.

OMG... Mobile bravia engine has apsolutely nothing to do with with that, because bravia engine works only in phones stock apps for viewing videos and pictures, and the effect is not even similiar to screen dimming. It brings more saturated colors and that is all.
Same problem is posted here: http://communities.sonyericsson.com/thread/61560?start=0&tstart=0 and Sony replied "I'm sorry that it has taken so long but I have done some testing now using a later software and I'm not able to replicate the issue that you guys report so I assume it's fixed." It is more than obvious that they like to close their eyes on every single problem that occurs. Thank you Sony for your gorgeous support to your beloved customers. I cant be more sarcastic, of course.

It's not my way, it's the way it is. If one understands what mobile bravia engine is, one could never offered it as a solution to a problem that has nothing to do with it. I'm terribly sorry if I ofended you, and I apologize for my attitude. I'm not mad at you, or anybody else here, I just don't see why would one write something just to be written. I know my T-Rex wery well, and I know there is no "normal" way to turn this dimming crap off, so I posted my question here, and expected that someone of the experts would offer some kind of solution to that. And I got things like "turn automatic brightness off", or "turn mobile bravia engine off" even though I previously mentioned that i tried all that stuff. People are "trying" to "help" me here, and they didn't even read what I've written. I'm really not one of guys that would post a question here just to be posted, I searched the crap out of the internet, and I found apsolutely nothing helpfull. That's why I decided to open this thread, to hear what experts have to say.

Thank you guys very much! Changed values, and rebooting my phone...everything is fine now, no more stupid dimming. However...I noticed that color adjusment is still visible when changing from dark screen to colorfull bright one. So the dimming is now definitely gone, but that color adjusment is still visible, like it changes contrast a bit, from worse to better, it is clearly visible. Any ideas about that?
I'm uploading a video I recorded with my webcam to get you a closer look. I'll post a link once it's uploaded.
Video will be live here in a couple of minutes: http://youtu.be/fHozO8zGZ1Y
After I managed to turn off DLS, that auto-contrast thing still remains. If you look closely, you'll se that the blue facebook stripe (and everything else) slightly changes its color/contrast when returning from the gray screen. But DLS was much bigger pain in the ass and I'm very pleased with the result od turning it off.
