Galaxy S6 :: How To Turn Off Or Adjust Capacitive (hardware) Button Lights On Phone

Apr 12, 2015

I have a Verizon Samsung Galaxy S6 Edge, but I believe that these instructions should work on the S6 as well. On the Note 4, there was an option to adjust the Capacitive buttons lights - always on, always off, 1.5, and 6 seconds. On the S6, this option was removed from some variants (I believe that the AT&T version still has this option). If your phone doesn't have this option, then you can change the capacitive button light settings through ADB.

1. If you haven't done so, you will need to set up SDK on the PC/Mac first: Installing the Android SDK for Windows, Mac and Linux: A tutorial | Android Central

2. Enable Developer options by going into settings-about phone,and press on the Build Number 7 times.

3. Plug in the phone into the computer. Wait until the phone is recognized in the File Explorer (in Windows 8 on the Metro Screen, type "File Explorer", and select it). It should say Samsung-SM-G925V (or similar) in File Exporer

3. Go to Settings-Developer options, and enable USB debugging. A pop up menu will prompt you if you want the computer access, so select "Yes".

4. Go to the Command Prompt(in Windows 8 on the metro screen, tpye "command prompt", and select it) and type "ADB devices". You should see a device connected.

5. On the Command Line, Type "adb shell settings put system button_key_light 0" to disable capacitive lights.

The options are:

"adb shell settings put system button_key_light 0" -> always disable the capacitive button lights
"adb shell settings put system button_key_light -1" -> always enable the capacitive button lights
"adb shell settings put system button_key_light 1500" -> always disable the capacitive button lights after 1.5 seconds
"adb shell settings put system button_key_light 6000" -> always disable the capacitive button lights after 6.0 seconds
"adb shell settings get system button_key_light" -> get the current setting (standard: 1500, ie. 1.5 seconds)

Motorola Droid 3 :: Capacitive Button Back-light?

Aug 3, 2011

From day one the D3, i received on july 8th after placing a phone order, seemed to have really dim button backlight. Well after a couple weeks i went into a VZW store to purchase an extended battery and noticed that the D3 they have out on display has very bright buttons. I've been very busy at work so i finally got around to seeking some tech support and thy are sending me a CLNR to replace mine. I wished i had sought out tech support a couple weeks ago so i would be getting a new phone and not one someone else returned.

Motorola Razr :: Wake Up Display Via Capacitive Button?

Jan 31, 2012

To use it one must press the power button,operation that almost all the time requires the use of both hands,and then swipe ur finger to unlock the screen.And u have to do it tens or maybe hundreds of times daily.Or having the phone in a car holder;that holder needs to be awful sturdy so u can just press with one finger the pwr but I couldn't pull it off. I need to grab the phone with my big finger and then using the index finger tri to find the little pwr button.I have to admit that I'm a big fan of physical buttons(I still weep after my Nokia 9300i) but also the solution provided by Galaxy S II with its physical home button sounds ok to me.I think that giving the user an option to keep or not the home button active would be a nice feature on the RAZR.

Motorola Droid Bionic :: Soft Button Lights Not Always On?

Feb 26, 2012

I've had my Bionic about a week. The 4 soft buttons along the bottom of the screen (is there a common term for these?) are not always lit up. They all light up or they all don't, it's not just one of them. They're lit when I wake up the display, they'll go off after a while, sometimes just stay off briefly, other times stay off for a while. Is there any protocol for when the lights should be on or off? Is this a defect I should be concerned about?

Galaxy S6 :: Capacitive Buttons Not Lighting Up

Apr 27, 2015

For some reason, my capacitive buttons next to the home button aren't lighting up. Did Samsung do away with this? Since I'm used to the way they work, I know where to push the button to go back or to open recently opened apps but I'd like to have them lit if I could.

Galaxy S6 :: Capacitive Buttons Light

Nov 29, 2015

I don't know if I post this in the right section. I just wanted to let others know that I've found a way to disable the light from capacitive buttons even if the phone is not in Power Saving Mode, and ofc without any third party software.You dial *#0*# and you go to the bottom and press "Black". Now, if you hold the power button you can chose to restart the phone and the backlight will stay off. If you press volume up key after you pressed "Black" it will just exit.At first I was thinking I broke my phone. Then I realise how it works.

Galaxy S6 :: Capacitive Buttons Not Working

May 24, 2015

I have the Verizon variant of the Galaxy S6

A few different times now the capacitive buttons stopped working. They don't light up, they don't work, and there is no haptic feedback from them. It always happens after a restart, but not the first restart.

I have tried factory reset and that didn't work. I had to flash my phone using Verizon's repair assistant to fix the problem.

The second time it happened I thought it was due to installing that Galaxy Lights app everyone is talking about. I booted into safe mode, uninstalled the app and restarted. Once I did it worked for a few more days before it happened again.

A few minutes ago it happened again. This time I haven't installed that app or any other apps that would affect the buttons. I am rooted with Ping Pong but I haven't done anything other than remove a few bloatware items and use Titanium Backup.

BB Torch :: Front Panel Bottom Button Lights Staying On

Feb 25, 2012

I'm having an issue with my new Torch 9810 where the 4 front control keys remain illuminated after the touch screen dims out (phone answer key, blackberry key, return key, end call key). The only way to fix it temporarily is doing a battery pull but after about an hour it happens again. Really drains the battery down fast. I've gone as far as deleting all the installed apps, checked for updates etc but still ongoing. Phone is only 2 months old. Please help. ThxTorch 9810O.S 7.0 bundle 1328 (v7.0.0.254)Rogers wireless

Galaxy S5 :: How To Turn Off Multitask And Back Button

Jun 21, 2014

I have recently switched to from the iphone 4s to the new Samsung Galaxy S5. Everything about the phone is great except the annoying multitasking and back button that i keep accidentally "touch" when playing games, watching full screen vids, etc. Is there a way to make the side "buttons" less sensitive or move it to the home button like the iphone? This way, I can hold the phone with both hands and not accidentally stop what i'm doing by literally/barely grazing those two corners.

Galaxy S6 Edge :: Duplicate Backlight Reflections Of Capacitive Keys

May 6, 2015

I got an S6 Edge Gold phone last week and noticed a weird duplication of backlight reflections of the capacitive keys.

There is an original light, and then there are two more reflections which is very weird. I can tell they are reflections because as I tilt the phone those two reflections change angles while the original light stays in its spot.

The issue is also with the notification color lights. When ever it blinks I see two reflections (one above and one below). So it looks like a grain of rice instead of a small circle.

Please see the image below for a better understanding:

My inspection of the device tells me that theres something wrong when the different layers of glasses were stacked. I have looked at some other Edge phones and they don't have this issue.

I have also seen that when very bright light shines in all angles and when the phone is tilted (with screen turned off) and observed carefully I see diagonal lines on the entire screen with a space of about 5mm each. It is very hard to see them, and when I turn the screen on I can't see any flaw.

Lumia 1520 :: Why Phone Capacitive Buttons Flickering

Jan 5, 2015

Recently the back, and start buttons on my 1520 have not been turning on, or flickering. The search button has not shown any signs of the issue. The buttons still work, and have no functionality issues.

It started randomly, and I notice if I press on certain parts of the phone, the lights may go on or off. They may also go on or off of their own accord.

I had dropped my phone a few days prior, but there was no visible damage, and the issue was delayed.

I'm assuming this is a hardware issue and I would need to replace it in order to fix it, but are there other possibilities?

Galaxy S6 :: Power Button Not Working Can't Turn Back On

Oct 30, 2015

It appears that the power button on my Galaxy S6 isn't working anymore. I have faulted this with samsung and they have asked me to send it to them for repair. Today, I was going to back up my phone but my battery went flat before I could do this and now I cant get the phone back on!! Some have suggested holding down the volume up button then plugging in the usb lead while connected to a computer, it didn't work. I have also tried the volume down button and the home button at the same time while plugged in via usb, this didn't work either. how I can get into recovery mode without using the power button, I really need to get the phone back on, the battery is sealed in.
