Illumination bar - Sony Xperia S, Acro S, Ion

How to increase the bar brightness level?
I am using kernel based on stick ROMs so when I switch on my xps the illumination bar lights up with full and high level of brightness which looks very nice.
But when phone has started the brightness level is very low as compared to level when xps was starting up.
I have used illumination bar apk to increase the intensity but didn't manage to attain that level.
Please help..or suggest.

use search next time. there's already a thread about this..
so: your xs need to be rooted, then via root explorer (or other apps) head to /system/etc then find hw_config.sh open it via text editor then find "echo 2000 > $dev/button-backlight/max_current" change it to 20000 to get max brightness for illumination bar.

i have been facing a problem like this,i have installed "OpenSEMC-mr2-alpha2"
when i control my brightness the illumination bar light remain full
but in stock ROM when i reduce my brightness the intensity of that illumination bar light will also decreases .
it is very annoying if you are doing something in night with low brightness and the illumination bar light is full.
please help

[Q] Screen Brightness

hi, i'm using HTC Desire HD with leedroid rom and kernel.
i read that to save more battery, i must turn down the screen brightness to a low level. but i want to use the auto brightness function but sometimes it isnt accurate to the environment(sorry for bad english). uhm any tweaks or mods that has customized auto brightness? thanks in advance guys
I found that the best thing to do is to do it manualy by using the brightness level app on the market which has a slider on it.
I use Tasker to set the screen brightness to levels defined by me in response to ambient light levels. Takes some experimentation to get it working right, but it's worth it.
Or then you can switch to CM7 as it has all screen adjustments built in the settings i.e automatic screen dimming level adjustments, different levels etc etc.

[Q] Decreasing screen brightness under 20 on rooted stock JB 4.1.1

Whatever program I use, I cannot lower the display brightness below 20. I did my best to search the forum as well as the web, but couldn't really find an answer to this. Sorry if I am (possibly) repeating..
I am on stock rooted JB 4.1.1.
My question:
How can I user lower brightness levels? Do I really need a modified kernel for this?
Thanks.
How did u know its 20 % ?

it is not %20. It is 20. Screen brightness level can be set as a value between 0-255.
BTW, I am not talking about stock brightness slider in the status bar. Root applications like RootDim or Tasker allows you to set brightness in terms of actual brightness level. However, values under 20 don't have any effect on decreasing brightness..

LED Notification brightness !

Hi all
I'd be interested to know if anyone else finds the led notification light on our ZL is just not bright enough, I really struggle to see it flashing when out in direct daylight especially on a sunny day. I use my ZL as a business phone and rely quite heavily on the notification led for emails and sms notifications when quickly glancing at the phone in meetings and out on site visits, on numerous occasions now I have not responded to emails and sms as quick as I would have liked due to not noticing the led flashing when out in sunlight.. I've done a bit of digging about on forums and Google but cant find any suggestions on a way to adjust the XZL led brightness, there is a mod for Xperia 2011 devices which I've tried but unfortunately this doesn't work on Sony's latest devices,I've searched the system files and build.prop but cant find any reference to the led brightness.
So with this said I would be grateful to find out if anybody knows where the led control files in the system files are located or better still a mod that can adjust the brightness.
I'm using Illumination Bar Notification from playstore. You can adjust colours and brightness, but I don't think you can make the light brighter with this app.

[Q] Xperia S led bar policy with Opensemc-U RC2

Hi,
I just installed the ROM OpenSEMC-U CM 10.1 RC2 on my Sony Xperia S and it seems to be working just fine except for one little thing :
The led bar for the buttons lights up every time I touch the screen whereas it only lit up when hitting the buttons on the offical ROMs.
I already searched the forum and some advised to look for an xposed module that would do this.
I didn't find any.
Do you have a solution ?
I you only have a few information on how it's handled in the system, I could try to build the xposed module myself but I don't know where to find the part of the system handling this functionnality.
I would have posted this in the right development forum but I don't have the rights because I juste created my accout...
Thanks.
Regards.
Up !
Does anyone have an idea ?
Thanks.
I've come across some posts about the sys files controlling the leds :
I've seen you can change the lightning behaviour by changing values affected to the virtual files /sys/class/leds/button-backlight/ ...
The problem is that there are several values I can change and I couldn't find any documentation. For example, I wonder if the file trigger cannot be set to a value for which it only lights up when the buttons are touched and not every time the screen is touched.
Regards.

If we can figure out which parameter to change, we can then write into thoses virtual files in the hw-config script file, which sets the parameters right on startup.

Colour change at min brightness.

MY issue with the stock Rom, which has been bugging me for a while is that when I reduce the brightness to the minimum, the Contrast changes, or something of the sorts, this really annoys me and I would like to disable it. Can someone help me out? I really don't want to flash a custom ROM.
I think that's normal because of AMOLED display, I also noticed it on CM14.1
This is simply the way this particular screen works, can't be fixed with software.
You can only avoid it by not reducing brightness as much. According to "Lux" the color shift starts under 4% brightness.

But why does the min brightness in mxplayer not have this issue?

Because mx player doesn't set the brightness as low as you can set it manually using the brightness slider.
Select menu - display - settings - screen - untick "brightness". Now you can set your brightness manually to even lower using the brightness slider.
Other apps seem to work similarly (for example an third party brightness widget)... Not setting it to minimum... Like they don't recognize the "real" minimum brightness - which is lower. I don't have this "issue" on my tablet. Haven't looked much into it though.
