How to turn off the button lights?

Does anyone know of an app or a setting to control the touch button lights at the bottom of the screen?
i tried searching for a solution but found none.
I like reading off of the kindle app at night and with 22% brightness and white text on a black background, the result is a perfect experience -- except for the four blinding leds every time I turn the page...
This might also be helpful for those with issues during streaming video (i.e. Netflix).
I apologize in advance if this has been dealt with/is in the wrong place.

That is a very good question and I have the same problem while reading on my phone. I'm going to try and do some research to see if I can come up with a solution.
Try this. I don't know if it works or not yet

lol!! thats great.

Bump for a good question

the light buttons are bright as fkc at night. +1 good question.. probably saves battery too if someone can dev this app.

Install BLN control and check Activate Notifications. The lights will only stay on for a few seconds after you touch the screen/buttons.

Thanks for trying guys. I want to completely disable those bad boys. I know where they are. Don't need a searchlight!

Well you can't disable them. Not even the stock roms let you do that, the best bet is for them to only blink, which is they turn on when you're using them.

Some black tape works lol

Would the touchscreen still work with black/electrical tape? That makes me wonder, but I am lazy and have none on hand to test out.

Dim Softkey brightness? Is it possible?

Is it just me or are the softkeys really bright on the s2?
Well, ive gone on google and tried to find the answer, but seems like there is not a way to possibly reduce the brightness of the softkeys itself.
However, before i give up (i find those softkeys useful, but hard to use at night as its too bright, and turning off the function is difficult to use) I was wondering if its possible without rooting, by using a 3rd party app.
Thanks

That's an interesting idea. The brightness issue made me turn off that light all together (running CM9). I found the light so distracting when using my phone to read a book or something in a dark room at night...
I hope someone chimes in with an idea.
.

Seriously doubt its possible without root.... with root, the only ones i can find just turn them off.. havent seen anything that just dims.

Would definitely say impossible without root, as you need to edit system files to alter hardware functions. I don't believe there is a variable anywhere to edit that though, because I've only ever seen their functions to be off and on with all the phones I've used that have had them. Just my 2 cents, but I'm sure a skilled dev could give you a better opinion.

Darn alright thanks for your posts!
Hopefully a dev could give his $0.02, as i would believe it would make the softkeys more usable throughout the day and night.

i think over time you get use to it. i turned my keys off and i have no problem navigating.

That's true. But I think to me its that little add on that makes everything nicer. However, just my opinion though.

Use the app screen filter. It will allow you to dim the buttons. Not sure if root is needed or not tho.

Didn't work for me either, however, I like the the function of the app for screen brightness.

What rom are you guys on? I'm on AOKP B40 and screen filter worked perfectly. Much easier to dim than with Lux, and back light for keys turned off and on perfectly.

I'm not sure exactly how these specific leds work, but I know with store bought leds, you can use what's called multiplexing which makes them flash faster than your eye can see, but slow enough that it seems as if they are dimmer...not sure if there is a way to lower the speed or if you can even make them flash at all (constantly)
You could also maybe look for a night mode from a third party app to change settings at a certain time

That said.. I wonder if its safe to have a an app to lower voltage/amps to these leds.

[Q] disable soft key lights?

I know my phone. We are very intimate. I know just where to touch her. I don't need the keys blinding me. Can I disable them, permanently? I never want to see these light up again!

If you really want to disable them permanently, it's a one-line change in the kernel. You basically don't tell it where the light switch is .
Which ROM are you using?

Code:
gpio_direction_output(_3_GPIO_TOUCH_EN, onoff);
Well damn, looks like that might not only have turned off the backlight, but also the ability to use the button. Black electrician's tape is probably an easier solution if that was your goal.
Somehow I think you still want to be able to use the buttons though.

Isn't there another line of code that tells how bright the keys can be? Is it possible to set that at 0?

Also could you upload the kernel where the back light keys don't turn on and don't work? I think it would be useful for people who want to use the ice cream sandwich soft keys

I'm not trying to hinder development, but in my opinion I would rather them spend their time on stuff that is less cosmetic... that stuff can come later because there are more important issues they are working on. I'm sure it will one day get fixed...

Sometimes a little distraction is nice. Trust me, after you've been staring at VCO divider tables for a while, something simple like "Can you just turn off this light?" is a good way to improve productivity. I'm back in the tables again this morning, but this gives me something interesting and rewarding to do during the roughly hour and a half a full build takes.

no one here is asking the main devs for this fix anymore....its already been said several times they dont know....sooo maybe other people in here can try to figure out a fix.
So have a nice day.
Also its not just so "cosmetic" as you think.....the people that are on ics based roms would truely appreciate this fix due to the amount of battery life gained if those damn lights didnt stay on.

I would like to know which line this is as well. I dont need extra keys in beam. I want just the hard keys

I do agree that it would be nice. Think about it the only time the lights are on is if the screen is on, if the screen is on, chances are you are touching the screen unless you are watching a movie... there are a few roms out that don't have this problem like the beam port... Maybe compare roms and kernels? There is bound to be a solution. I hope you find your answer and sorry i wasn't trying to blast anyone.

Its all good....i watch alt of movies while sitting at the back gates waiting for the parks to empty out at Disney so i can go to work and the those lights are quite annoying in the dark watching movies lol

GOOD NEWS EVERYONE! Theres an app called screen filter on the market that does the trick by turning off the softkeys umtil you actually click them details are on my capacitive buttons thread.

Its kinda old news...but it does work but its just more steps for getting what you want......when it could all be avoided

Awesome app, must try! Gravity Screen Off

https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenofffree
This app uses your phone's motion, gravity, and proximity sensors to automatically turn on and off your screen so that you don't have to press any keys (software or hardware).
For instance, when I put my S4 inside my pocket or holster it to my belt clip, the screen turns off automatically. When I take the phone out, the screen turns on automatically as well.
I've tried a few apps similar to this before but this one just works very well and consistently.
I already installed it on my mom's and wifey's S2s and they love it too~! Just wanted to share the goodness~

Wow it is pretty impressive! Thanks for sharing. .

No problem. I figured there must be others who will find this kind of app convenient to have around. I just love not having to press the home or power button every time I want to turn the screen on.

Any hit on battery performance?

The author of the app said to expect a hit about 5%. I've been using it for 2 days now and I haven't noticed any difference so far. But then, I'm running on the ktoonsez kernel with -50mV, all-around.

Freekin love this app

Thanks for the heads up op! works like a charm, now I've got to get used to not pressing my power key on wake

Sweet app....I noticed I had to lower the sensitivity while my phone was in my mount while driving. The screen kept coming on.

Nice catch. Love this app.

This is exactly what I was looking for!! Thanks for the find!

The only time the screen turns off on me when I don't want it to is when I text and I accidentally rest one of my fingers over the proximity sensor by mistake. Otherwise, it's been good. I wish there was a time-delay option for proximity sensor to turn off the screen so an accidental finger covering up the proximity sensor doesn't turn off the screen right away.

I see. It's an extra step but you could pull down the notification menu and pause the app before gaming then turn it back on afterwards. My mom tells me that sometimes when she's watching Netflix, the screen turns off on her. I told her not to cover up the sensor but she just disabled the app.

According to GSam battery monitor, Gravity Screen Off is responsible for only 0.2% battery drain. I haven't noticed any extra drain because of this app.

[falsified] See Your Pulse on Lockscreen

Ok, so I do not know if anyone have noticed this already, but you might find this interesting.
When you pass your finger over the Lockscreen without actually touching it the phone draws a ripple effect along the path of your finger,
Here's what I found; if you hold your finger steady close enough over the screen without touching all the way, you can see your pulse!!
The way I see it is, unlike the s4's lockscreen where you have a dot following you while you hover, the note's lockscreen draws a circular ripple below your finger that changes in area as you get closer. So, if you don't change the distance between your finger and the screen, the only thing that is changing the capacitance between your finger and the screen is actually your own pulse fluctuating the electrostatic energy in your finger.
If you've read so far I hope I haven't wasted your time. I just wanted to share

Was skeptical but yep seems to work not sure my pulse is that fast though
Sent from my SM-N9005 using Tapatalk 4

Can a app be built arround this ? It's pretty cool

It's NOT your pulse. It's just an effect.
Try hovering your S Pen over the screen = same thing.
