Lost LED backlight for home/menu/back/search buttons - Thunderbolt General

Running cm7 and having problems with the soft key LED backlight. Sometimes they are on, sometimes they are not. Sometimes when i turn on the phone they are on, after I unlock they turn off after a few seconds. Nothing I do can turn them back on after they turn off but they will turn back on randomly. Is this common? Is this a warranty issue?

Has anyone else had this issue?

I've had that problem on all AOSP roms. Though luckily CM7 has an option to fix it. I believe it's under CyanogenMod settings and backlight settings. I don't quite remember. I'll have to check and let you know exactly.
Go to CM settings and then to Display. Select automatic backlight, scroll down and check use custom. You're going to go into edit other levels and in the right column you'll see buttons. The default is 30 and if you change the value higher you'll increase the button backlight and they'll stop randomly coming on.

That worked perfectly! I never would have thought to even look there. Thanks a

Does it do this in complete darkness? A lot of roms (or maybe it's kernel settings, or both) use the light sensor to turn off the soft key lights when it's bright enough to see them but when you're in poor or no light, they stay on. It should save you battery and I actually like it.
Think the first rom I used was gingeritis and it had this feature and thought my soft key lights were burning out.
If you already know this or if it was happening in darkness, then ignore my post. Maybe some dust got in your sensor?

It was dark enough that I couldn't read the writing on the soft keys so of figured something was up but I figured it out. Thanks

You need to get NoSleep!! or NoSleep_Raphael.cab (something like that). Diamond Tweek and Advanced Configuration can also help you turn off Fast Sleep.
Even with one of these installed, sometimes the Fuze confounds me and shuts the screen off during a long call.
But it has nothing to do with the brightness level that you select in Power settings.
Also check this thread http://forum.xda-developers.com/showthread.php?t=446306, and all of the Raphael forums.

Backlight for buttons

Is there a way to keep backlight on for the buttons at bottom?

KTLO does NOT work on the Infused despite what others say. It might work for a few minutes after initial install but then it gets all messed up. Try using it for an extended period.

I sure wish there was. The current design is stupid. I have an open offer of $50 for a DEV who would make an app that will function in Froyo and GB on the Infuse to do just that. If anyone is interested let me know.
Maybe they can reverse engineer "Keep the light On?" I was in touch with the DEV of KTLO and since he doesn't have a Infuse he said he can't do it. He also confirmed that KTLO is not compatible with the Infuse. I have it installed and sometimes it works for a few minutes then eventually it doesn't.
at least i am not the only one who think design is awful....why would the backlight turn off after like 5secs of not touching the screen? ugh
Agree!
Agree! the button lights tune off too fast.
I can't access the button in dark place. really stupid design.
I tryed the "Keep button lights on",, not work on Infuse.

Ok, my mistake. The "Keep button lights on" works fine on Infuse.
We must use it as desktop widget, then we can turn on/off the button
lights via touch the desktop icon.
Good luck!

You'll find that after using it for a little while it will cease to function. It is not compatible with the Infuse. Sometimes it will keep the lights on, sometimes it works in reverse, sometimes it keeps the lights OFF. It does not work properly (even with the widget). If you use the widget each time you want the lights on it will sometimes work until they go off. It's supposed to leave the lights on anytime the screen is on without further intervention. It doesn't. The widget is only supposed to enable or disable it.
In some (this XDA Premium app being one of them), but not all apps, I've noticed that the lights will come back on by touching the screen.

I try this app few days, I think it's work, the logic is:
1.Install:
Install it, put on desktop, turn on, remove it from desktop
2.Work:
The button lights will not automatic turn on while screen on.
but, once you touch any button, the button's back light will keep on
until the LCD off.
not perfect, but not too bad.
Would likely need kernel support - the current behavior doesn't bother me so it's a pretty low priority.
There's also the fact that messing around in the driver for the bottom buttons is a great way to create an unstable device. (As evidenced by the pain and suffering of those testing BLN implementations.)

BLN is mucking around with a lot more than just turning on the backlight. It's dealing with system notifications for various events. I'm obviously not a developer/programmer in any sense of the word but just "turning on the lights" when you enter the room should be a LOT less intrusive then making them react differently to each different shirt color of the person walking in. There is already an app that works on most other Galaxy S devices so I would guess it's something that shouldn't be terribly hard just to turn on the lights when you walk into the room and turn them off when you leave.
Again .... I don't pretend to know what is involved, just "guessing."

Touching ANYTHING in the backlight code of that driver can do weird stuff... Lots of potential for race conditions.

[Q] soft key backlight (key light)

Hello,
This is my first post, i'm facing a curious issue with the backlight of soft key not lighting anymore (the lights are on only on 4ext recovery) since i installed endy or PVT runny ROM. now i'm on Fallout and i would like to know if there is a specific parameter in the system that i may enable to bring back the lights.
Cheers
The specific parameter is called "darkness"
They do light up when is complete dark around you..
really ?
Dude, even in complete darkness (of the soul also ) they don't. is there a way to tune that stuff ?
That's strange. I'm on Fallout and my keys are lit even though it's quite bright. Do your keys light up at all on any ROM?

i can't findout
Well, they do lit on when i use apps like "screen filter" or when i'm on 4ext recovery touch, but they don't elsewhere, strange isn't it ?
rgds
Try covering the sensors and see if the light comes on. They're next to the HTC sign.

even in absolute darkness with my fingers on the sensor, no backlight on soft keys.
i'm sure there is a place where i can hit some parameters but i don't know where. if no one knows i'm gonna mount all partitions next weekend and find my way out of darkness. till then i'm back to black
Im facing this strange problem now with BlindICE 9.1.1. I used ParanoidAndroid 1.1.2 with auto backlight and it was like you said, if the backlight gets weaker the lights on the soft buttons light up.
Now with BlindICE and manual backlight, if i slide the backlight from low to high, the softkeys flicker... don't know if tis because of this specific rom, or another error.
gimme the light, tonight allright
Well well, no further steps to findout where the settings are done for auto-backlight.
I gueess Lowveld (big ping btw, and thanks for the great roms) know something about those settings, i remember some controls (rcmix i guess) where you can ajust the sensivity of the backlight and their brightness too.
Looking forword for some paths to follow
cheers guys

the exact same thing is happening with me, I'm running cm10 released on 16th nov by nk111 , on my desire s ..unlocked with htcdev..cwm recovery (touch version)..but the issue is as soon as the screen is turned of the backlight of the soft keys is again turned off.. which is quite annoying
one more thing i just found out is that , when i set my brightness to auto..the backlight on those buttons works just fine.. but i ussually do not keep it on auto..
did you find a fix for that?? please let me know also :angel:

Full of Problems

Ok, so i opened my phone yesterday only and i am already so frustrated with it that i might even sell it. Anyhow, i have the following problems:
1) The screen turns off automatically after 20seconds, even when i am keeping the phone my hand.
2) the 4 touch keys at the bottom do not light up 95% of the time. They randomly light up sometimes, then they turn off automatically.
What is this? How to solve these issues?

1. Screen will turn off in the specified screen timeout, if you want to increase it go to Settings\Display Settings\Screen Timeout
2.Touch capacitive button lights are controlled by proximity sensor which is placed in top right, when sensor detects low light it turns on the backlit of capacitive buttons.

Ok take a deep breath and calm down a bit. Increase the screen time out in display settings.. it does not matter if you keep it in your hand or keep it on the table, if you dont use it, the screen will be turned off, to save the battery and the display itself of course.
And the lights on the capacitive screen, they act according to the lighting in the room, you have sensors beside the earpiece. It takes care of the display brightness and as well as the capacitive button lighting. When they are not lit up, try covering the are around the earpiece with your hand the capacitive keys will light up.
And remember the thumb rule search before posting, google it or search in the forums.

Use a firewall like we use on our windows pc to avoid certain programs accessing internet. Best free app on google play is droidwall.

Not sure if there is a better way (maybe someone else will chime in), but when that happened to me on an old phone, I just swiped blind to turn brightness back up... ie boot up, wait for a while, hit the power button to wake up, swipe away your lockscreen as you normally would if you could see it, swipe down twice to pull down quick settings, and slide or tap about 1/3 of the way down from the top of the screen to pull the brightness slider. It's all still there, just at 0% brightness.
Or, you could try either a really bright light or a pitch black room and see if adaptive brightness kicks in enough.

Thanks for the reply. I tried everything nothing seems too work out.
Anyway I'm lucky that I had a nandroid backup saved in my PC. Just restored it. It working fine now.
Thanks :laugh:
