[MOD] Lower Captive Button Brightness levels to Stop Bleeding

jul644 · Feb 9, 2012

This is best done after you flash a ROM as you might lose some settings.
(I noticed my wall paper changed and i had to sign back into Google account)
---This framework-res.apk file is different for every ROM---

In order to lower button brightness levels You have to change values in framework-res.apk/res/values/arrays.xml and here is how (read whole post first )

These are stock HTC AMAZE values:

Code:

<integer-array name="config_autoBrightnessButtonBacklightValues">
        <item>255</item>
        <item>255</item>
        <item>255</item>
        <item>255</item>
        <item>-1</item>
        <item>0</item>
        <item>0</item>
        <item>0</item>
        <item>0</item>
        <item>0</item>
    </integer-array>

These are values should reduce the problem significantly

Code:

<integer-array name="config_autoBrightnessButtonBacklightValues">
        <item>190</item>
        <item>190</item>
        <item>190</item>
        <item>190</item>
        <item>-1</item>
        <item>0</item>
        <item>0</item>
        <item>0</item>
        <item>0</item>
        <item>0</item>
    </integer-array>

These brightness levels are corresponding to the amount of light that light sensor is getting - the lowest value is while in the low light the highest when for example your phone is in direct sunlight. Brightness values are defined by numbers 1 is the lowest possible setting and 255 is the maximum brightness that can be set.

As You can see I was pretty aggressive with lowering these values and yet the buttons are still bright in every situation. You can set them a little bit higher or lower in order to suit your preferences.

Here is a guide on how to perform this mod on any framework-res.apk using apk manager (thanks for the guide goes to desean):

1. Download APK manager and unpack somewhere

2. Grab framework-res.apk from your phone under \system\framework\ (e.g. adb pull) and place it in the "place-apk-here-for-modding" folder

3. Run Script.bat and select option 9

4. Once done, go to projects\framework-res.apk\res\values\arrays.xml and edit your values as per first post.

5. Once edited, compile the apk using option 11

6. Qn: Is this a system apk. Ans: y

7. Qn: Aside from the signatures, would .... least. Ans: y

8. Prompt: In the apk manager folder u'll find a keep folder..... done then press enter on this script. Press any key to continue . . . You have to go to "keep" folder and delete resources.arsc because arrays.xml have been changed. After this You can press any key in apk manager window.

9. Once done, input 22 in apk manager and select "unsignedframework-res.apk" by entering the number that stands for it. After selecting it You should see in apk main window in the top right corner "Current-App: unsignedframework-res.apk".

10. Now press 5 to zipalign apk. You will find your completed, zipaligned apk under place-apk-here-for-modding\unsignedframework-res.apk.

11.Rename it back to framework-res.apk and adb push the file back to your phone

To send it back to your phone

Code:
Prerequisites have...

The file you are pushing must be placed in the platform-tools folder of adb so if you are pushing file "framework-res.apk" this needs to be downloaded/copy and pasted in C:\android-sdk-windows\platform-tools

1: go to run and type cmd (or just open your command prompt)

2: cd C:\android-sdk-windows\platform-tools

3: adb remount

4: adb devices *if everything is set up right this should output a serial number*

5: adb push FFFFFFF.FFF /#####/###### *i hope my notes help here you need to put the file name in for the F(s) and in the pound signs you put the destination on the devices:

Code:

adb push framework-res.apk /system/framework

7. adb reboot this is how you finish

You have to copy the file to your phone with ADB or you will get a boot loop and have to re install your ROM.

If you have problems with apk manager showing java error (like it did) this post helped me fix that

Tried that. Will not work on a custom ROM because of init-d.

updated the original post, i dont have my amaze any more but these values should be low enough to fix the bleed but still see them!

Post back on your experience guys and if different levels work better

also if some one can do a before and after shot that would be wicked

im surprised not many have, i know leedroid has this under tweeks.
this is also great as you can edit the auto brightness levels, by lowering them you hardly notice a difference but you wont destroy your battery.

I just have this script run on boot

#!/system/bin/sh

echo 0 > /sys/class/leds/button-backlight/brightness
chmod 444 /sys/class/leds/button-backlight/brightness

In my case it disables them completely but you can replace the 0 with a value that suits you best and that will be your maximum brightness and it's much less invasive of a change to your device

thats very nice could i put that in the first thread? (do you just type that into cmd after a su command?

you would run it as an init.d script if your rom supports it, or there is scripter on the market which you can just create a new script and copy and paste it into it.

that or if your going to copy and paste it into a command prompt just remove the #!/system/bin/sh line.

keep in mind why I run this on boot is because it doesnt survive a reboot so it must be reapplied as such unless the rom you run has the number premodified before flashing (i assume, just a guess not a developer by any means)

I learned this trick way back with my EVO 4g and subsequent 3D I now ditched sprint and am on Tmo. I take no credit for it so share and share alike

XmentalX - I just created a g-script with that command and it works like a charm. thanks

Glad I could help that drove me nuts when I first got mine which is why I opt just to disable them muscle memory takes care of pressing the right ones in the dark

are you using adb to send the file back to your phone?

rubyman94 · Feb 10, 2012

Is there any way to do it on a non rooted amaze?
