Hey all so recently my galaxy s2 whites don't have the vibe/brightness they had before. Using the internet or gmail for example is where i am noticing the problem. Things I did before I started noticing this issue was clear ram/do a backup using cwm and let my friend use the phone. Any ideas what might cause this? and yes i have brightness set to 100%
Which ROM are you using? If you are on a stock ROM go to Display settings and there will be a Background Effect option, changing this may help you. Might sound stupid but check your brightness while you are in the Display settings. Also, I'm not sure on this but I think there is a specific brightness setting in the browser options make sure you have a look around there too.

Thanks for the quick reply. I am on the stock rom with brightness maxed/background effect on standard browser brightness is also 100%.
The white text/app icons in the homescreen/application drawer have the bright whites i want but when i actually go into an app they aren't as bright as before.
Hmm update when I have the internet browser open and click the search bar to type in an address the screen gets really bright as it was before but when i close the search window that brings up the keypad it goes back to the previous dim white/colors. pressing the menu button in an internet browser also has the same effect
I think I fixed it there was an option in display called auto adjust screen power that was checked. Does clearing the ram reset all settings back to factory settings or something?
For some reason I see the brightness changes automatically in certain apps.
The auto brightness is off and set to full.
The brightness dims in the following screens:
1. Open original browser it dims , if entering web address it is back to full. Chrome does not encounter same problem
2. Original samsung mail app (not GMAIL) dims. If writing a new mail (reply/forward) it goes back up.
The brightness in the browser settings is set to full (not auto).
I tried to find an answer on the web but could not find. It drives me crazy!!!
Must say that I have the phone for 3 months and it started only a few days ago.
the only thing I can remember is that I was on WIFI and it started to update apps but how can I know what was changed and [email protected]#$ed my brightness control?
I assume that you're using a stock (or stock-based) ROM. Try to enter settings and deactivate the power saving mode if it's enabled. Then reboot - just to be sure - and look if the issue is gone.
Can't think of anything else at the moment...
Hope it helps
In stock browser disable auto brightness setting.

I can't believe I missed it. I've tried brightness in stock browser, tried battery saving from brightness menu.
I just didn't notice the toggle of battery saving in the main menu.
Thanks...
Hah, nice to hear that youe problem has been solved
Hi Everyone,
This is my first post. Please pardon me if I am starting this thread at a wrong place.
I was trying earlier to find a solution for brightness change problem in ubuntu touch OS, but by going through the forum i couldn't find any way without restarting the phone.
Restarting the phone to change brightness, really ?
It's not very practical by the way.
I just figured out that I can change the brightness of the screen in Ubuntu touch OS without having to restart it.
1) Start the adb root
2) echo "100" > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/brightness
The value 100 mentioned above is just for example. The range of that value is from 0-255. 0 is completely screen off, while 255 is brightest.
Since, I have only tested this on my NEO V, just eager to know if it works for other devices as well.
People who have slightest of fear that they might be doing soemthing dangerous, should not try this on their phones.
Please let us know.
Eagerly waiting for your response
Note : Nobody takes the responsibility if you damage your phone by any means. It is always your resposbilty.
On yesterday's build, I could change it using the brightness bar in the battery menu of staus bar
Reboot is only fir make your change avaitable for the system

Brightness option
Hi,
I verified for my NEO V. I don't have any brightness option.
I would assume that brightness is not available in the system bar other that nexus devices or officially released devices in ubuntu site.
I want to reduce the minimal brightness from 20 to 10. Now I use the app YAAB, but can this easier?
I set in build.prop ro.lcd_min_brightness=10 and find this in /sys/class/backlight/panel/brightness correctly, but see no effect

Do you not have a brightness adjustment in your rom settings?

Sorry, I gave too few info: I wonna stay on TW-base and there's only the slider, which doesn't make lower brightness than 20 (with the edits, I mentioned).
CM-, AOKP-roms offer manual adjustment and with that I got lower brightness.
I use this app when I'm reading something at night:
https://play.google.com/store/apps/details?id=pt.bbarao.nightmode
You may invert color to turn whites into black and reduce screen consumption, w/o installing or tweaking anything
I use black themes and I can adjust brightness lower than 20 by an app. My question is&was: how can I simply adjust it by system-value?

Thanks for the suggestion, good tip
I'm running the recent SlimKat (OmniRom-based) now. But I don't get brightness lower than 20 by settings, too, even if I set in build.prop ro.lcd_min_brightness=5 and in brightness-settings 0lux /0%. Strange...
I found this xposed module, 'screen filter', works great!
Hello, I use this application called screen filter, hope you serve https://play.google.com/store/apps/details?id=com.haxor
@bruno.filter: I use it, too. Slim and easy. @Joker87: I avoid xposed atm, because almost every discussion with dev's about any bug begins with 'if you use it, sorry...'
Change the minimum brightness level from usual 10 to 1. It doesn't modify the autobrightness level map so automatic brightness won't be lowered (though it can be easily adjusted on CM11).
This is so far exactly the same as GravityBox offers (modifying 'config_screenBrightnessSettingMinimum').
But Minimum Brightness offers one unique feature - it also modifies the lower brightness levels in MX Player (free/paid). Because no matter whatever you use manual or auto brightness, MX Player always uses minimum brightness of 0.05 (12/255, 19/255, 27/255, 36/255...). To actually lower the brightness, you would have to turn off brightness control in MX Player or use one of many 'overlay filter brightness app'.
So Minimum Brightness module retains the same quadratic function for brightness levels but includes lower values (1/255, 4/255, 9/255, 16/255, 25/255...).
Minimum Brightness uses value 1/255 which might not be suitable for every display (meaning LCD) but it suits perfectly my Super AMOLED screens (Galaxy S5 / Galaxy Tab S 8.4) and watching videos at night is still enjoyable.
There are many excellent auto brightness apps (Lux, Darker etc) that can use overlay filters to lower brightness even more so it's up to everyone to try and decide.
This module has been merged into new module http://forum.xda-developers.com/xposed/modules/mod-xposed-tweaks-cm-t3279109. Please check that module for any future updates.
Hello! Thanks for the mod, I will test
Works very nice on Xperia Z2, however minimum brightness is absolute darkness Could you please add an option to define minimum brightness value?

The situation is the same on my Xperia SP. When I set the brightness to miniumum the screen is totally black, also when the backlight decreases after 10 seconds screen gets black.
Hi! Tried min brightness but when screen is set to the lowest level, I get a white screen after locking the phone.
Sent from my DIAMOND D1 using XDA Free mobile app
Really great tweak!! I'm noobie in Android enviroment with my new Elephone P3000S and the lowest screen brightness is to high for me so your tweak is very usefull.
I also have the issue that the lowest brightness level sets the screen completly black and I have been scared for 1 hour truing to solve a completely black, touching all buttons but the phone didn't "wake up". Finally, pressing power buttom + volumen up + home soft key it has worked :angel:
So it would be very important to prevent black screen by allowing the user to set the minimun level.
Thanks!
Hey, I know making GUI is a pain in the ass so can you please make alternative version with minimum brightness set to 2? That will satisfy most of people complaining here. Your app is currently the only dimmer working on lollipop.

I will have a new device soon so that could make me change my mind about lowest value and UI.
@Dri0m
In the first post you can find archive containing multiple versions of module with different low values.
How to disable this module...?
I installed this module last night, enabled it in Xposed Framework, but did nothing with it. Then this afternoon I opened the Settings menu, went to Display, and before I could do anything else I received a phone call. As I terminated the call, the screen flashed, the phone rebooted--and after restarting it is completely, or almost completely blank. If I repeatedly tap the power button I get a fraction-of-a-second glimpse of the SIM PIN screen at normal brightness. This leads me to the suspicion that, by some weird combination of bad luck and an accidental touch of a finger after terminating the phone call, that the Minimum Brightness somehow got set--although why the phone then rebooted I don't know.
Anyway, by luck and good judgement I finally managed to enter the correct SIM PIN and then the phone unlock PIN. However, I can do nothing else. The screen is still blank, and as the phone is currently unlocked I don't want to touch the power button. Before sending the phone back to the manufacturer or anything drastic like that, I would like to try disabling the Xposed Framework. Whilst trying to find something useful in Windows Explorer I found Xposed-Disabler-Recovery.zip in the Internal storage\Android\data\de.robv.android.xposed.installer\files folder on my phone. I assume that this should be what I need. However, as I cannot see anything on the screen I would need to know the exact buttons to press, in which order and how many times etc, in order to enter the Recovery menu and do what is needed. According to the phone manufacturer the OS is unmodified Android 4.4.2., although strangely they will not even tell me which keys to press to enter the Recovery menu (long story, the upshot is, they flat out refuse to help apart from suggesting returning the phone).
Note that I only suspect it is the Minimum Brightness module that is causing the problem, however the problem did not exist before yesterday (when I installed the module), and as I was about to do something with the brightness when the phone rebooted itself, it seems too much of a coincidence to be anything else. If I cannot disable the module/framework, the only other thing I can think of is a factory reset--but again I would need to know exactly which buttons to press, in which order etc. Unfortunately at the moment USB debugging is not enabled, and again without the screen I cannot access it to turn it on.
Any help or suggestions hugely appreciated.

@Papalazzzaru
Xposed now sports a safemode which allows you to disable Xposed during bootloops. To disable Xposed, you'll have to repeatedly tap one of the hardware buttons (Power, Volume, or Home) on your device during startup.
During boot, your device will vibrate twice when it detects the first key press. You'll then have five seconds to press that same button four more times, with each keystroke producing a short single vibration. After ending with a long vibration, your device will disable and prevent most of Xposed's actions, allowing you to easily troubleshoot problematic modules.
Sorted
Outstanding, thanks.

The MX Player part still works. I don't know about the lowest value of brightness in general but at least with CM12 & Samsung the brightness goes to the hardware minimum by default.
Thanks, this is exactly what I want.
Could you make it for LP ?
I want my phone be absolute zero brightness for driving navigation.
Tested it on CM12.1 Nightly on the Nexus 6. It works here, but on 0 the screen is a bit purple. However, I guess this is the screen's fault

Yes it works
This module seems to be working well on the Moto X Pure Edition (Motorola xt1095) running Lollipop 5.1. It's an AMOLED screen, and I personally find the minimum brightness on 5.1 too bright, so this has helped solve that.
