Controlling the LEDs

I've been looking for how to control the LEDs on our blade for quite some time now, and, since I didn't find anything, I decided to try myself and succeeded.
Heres the How-to:
1. Install the Android SDK(Or just ADB)
2. Run "adb shell"
3. Run any of these commands:
Activate Backlight-leds(White): echo 255 > /sys/class/leds/button-backlight/brightness
Deactivate(White) echo 0 > /sys/class/leds/button-backlight/brightness
Activate Red leds: echo 255 > /sys/class/leds/red/brightness
Deactivate echo 0 > /sys/class/leds/red/brightness
Blink: echo 1 > /sys/class/leds/red/blink
echo 0 > /sys/class/leds/red/blink
Activate Green leds: echo 255 > /sys/class/leds/green/brightness
Deactivate echo 0 > /sys/class/leds/green/brightness
Blink: echo 1 > /sys/class/leds/red/blink
echo 0 > /sys/class/leds/red/blink
Just a little tip: If you want to control the green or red led, you have to "deactivate"(Turn off brightness) of the White ones..

yellow is red + green.

Hmm, that makes sense, for some reason i can't get it working, the red led just keeps overriding the green
Edit: The only thing I'm able to make thus far is Orange with Red: 100; Green: 255;

is it possible to run this commands inside an android app or shell script without adb?

typically yes. you have to invoke the "sh" command when using an app so that it can also port root permissions to superuser to grant. i am working on that for my thunderbolt. my attempt will be to set the LED to full brightness (beyond the 128 setting that the system allows) and get the LED to stay on for more than the 1 second that it does. YES i am aware that setting my LED to beyond the default max can of all things shorten the life of it. i really dont care about that. i have insurance on my phone anyhow. so if i break it, i pay the copay and presto! new phone.
anyhow, back to the topic at hand...
so, i will get to programming that shell command pretty soon, once i figure out how to integrate and build apps to android... lol. i know how it works in theory, and know linux commands, but its another thing entirely to build something and have it work.

Hello all, need a help solving a problem. I want to switch the back -led on and off. i can access the sys/class/leds/button-backlight and can change the brightness of the variable to "170", the thing is the variable's value is changin, but the LED is not glowing! ,i tried "1" and it has the same response. Lemme post a screenshot indicating my situation here!

[FIX][CM12] LMK Fixer and ADJ

I make my own script for LMK (low memory killer) and adj.
Init.d doesn't work on CM12 so the unique way to make it automatically at boot is with an paid app.
"Boot Shell + Pro Version" (no spoiler)
1. Download Boot Shell and buy Pro version (you also can "buy" it on Aptoide , but highly recommended support the developer is the correct way)
2. Open it , in lateral menu and select "New script" and put it a name. (Ex: LMK)
3. Copy and paste it:
Code:
chmod 644 /sys/module/lowmemorykiller/parameters/adj
echo '0,58,117,176,529,1000' > /sys/module/lowmemorykiller/parameters/adj
chmod 644 /sys/module/lowmemorykiller/parameters/minfree
echo '12288,15360,18432,21504,24576,30720' > /sys/module/lowmemorykiller/parameters/minfree
4. In app settings select "Execute script at boot"
5. Restart and enjoy best RAM management

Does Music apps run better on background? My only problem with CM12 was that Google Music closed A LOT while on background.

Yes is for that , better ram management

Hi,
I don't want to sound rude but am I supposed to get partial credits for this?

I forgot it , sorry @BlueFlame4

How many apps can you run in the background now? Do you also have Facebook app inbetween them? Wasn't there an app called Kernel Audiator which does the same thing?

XT1033 CM12 Nightly. Upon screen off this script undoes itself... No clue why

Odd, it works on the weekly build and on the Asia retail soak...

good job
This script does the work. Thank you man @Lans98. I really needed multitasking which is absent in current cm.
Well I have a query
can i just place the script in init.d folder to make it work?

Working 100% for me now. Cm12 nightlies. Xt1033. Thanks

Why is showing an error when I select "execute and show output"? Then I suppose it does not execute fine at boot :S

Disable swipe-up lockscreen?

How do i disable the swipe-up lockscreen? I don't see anything in settings to disable it.

You want to got rid of this lock screen?
Using Activity Launcher:
1. Install Activity Launcher from Google Play or APKPure
2. Open Activity Launcher
3. Scroll down, select Settings and find the activity Settings$ScreenLockSuggestionActivity
4. If in lock screen settings, select None
Or if didn't find, try another way:
Disable via ADB:
1. Enable ADB in developer options
2. Connection your Fire tablet to your PC
3. Enter this command
Code:
adb shell
settings put secure lockscreen_disabled 1
4. Reboot
Code:
adb reboot
Or you want to watch a full tutorial on YouTube:

Disabling it via adb didn't work for me on Fire HD 10 2019.
Setting Keyguard to off in Tasker works for about a day. Running the task on device boot, you may need to wait a few seconds, and then running it every few hours should keep it off.

That did the trick, tried the adb thing before but it didn't work.

activity launcher helped me to get rid of the lockscreen. Unfortunately, I tried the ADB command before, this did not work and either disabled the activity entry. So i had to revert the ADB command with value 0. But anyway, thx a lot for the hlp here in the forum.

For what it's worth, this is a copy & paste which is my solution for non-rooted devices:
I use the Gravity Screen app on a non-rooted Fire HD10 (2019) which uses motion to unlock/ wake up the device which you can get here.
I have the app set up to "Turn Screen ON by Motion" and under it's "Special Settings", I have "Disable Lock Screen" checked:

}

What worked for me on my 8th gen HD 8 was:
Step 1: Disable screen unlock in the official system settings:
Step 2: Run this:
Code:
adb shell locksettings set-disabled true
I got some error messages from locksettings once when I was trying this. If that happens to you, try this more elaborate version:
Code:
adb shell
settings put global LOCKSCREEN_AD_ENABLED 0
settings put secure lockscreen.disabled 1
locksettings clear
locksettings set-disabled true
exit
Interestingly, after a reboot LOCKSCREEN_AD_ENABLED goes back to 1 and lockscreen.disabled goes back to 0, but the lockscreen stays disabled.

[TIP] How to Enable 2 Button Navigation on the OnePlus 8 (no root)

Presumably this also works on the OnePlus 8 Pro. Here's hoping it also works on Oxygen OS 11.
If you search under Apps and Notifications, you may notice that the OnePlus 8 still has a hidden "2 Button Navigation" App installed. That's because it's still capable of using it, even though there's no option to do so in Settings. You can enable and disable it using adb commands.
You must enable Developer options to access adb commands (Tap build number in About Phone until it tells you that you are a developer. Go to Developer options and enable "USB debugging").
If you are on Windows, download the minimal adb fastboot zip here, then extract it to its own folder and click cmd-here.exe to use adb commands.
Plug your phone into your computer. Type "adb devices". Make sure only one device appears (your phone should be the only android device plugged in . If your device appears, check your phone to see if its asking permission to use debugging over usb, then grant it.
The following command will enable the 2 Button Navigation Bar:
adb shell cmd overlay enable com.android.internal.systemui.navbar.twobutton
To disable the 2 Button Navigation Bar:
adb shell cmd overlay disable com.android.internal.systemui.navbar.twobutton
It's as simple as that. :good:
Swiping up from the Home button brings up Recents, and tapping the Home button goes Home, like it should.
If you are using a third party launcher, you may have to swipe up and hold to get Recents to appear while you are on your Homescreen or App drawer.

If Oxygen OS 11 still has this hidden app, then these commands should still work after updating. I would also disable 2 Button Navigation before upgrading to Oxygen OS 11 from 10, just in case. You can enable it afterwards as long as it still exists.

Does it work for Realme/color OS too
