Stop the backlight turning off (during a call)

Holding the power button down turns off the phone - As everyone knows.
Pressing it just turns the backlight off. Is there a way to keep the backlight on pernamently? Especially during a call. When the light turns off I can't touch the keypad or write notes then, I want it to be pernamently on during a call and even when not used (Obviously unless i press the power button that turns the backlight off).
Thanks all for reading and hope you can help.

first off check ur setting and make sure proximity sensor is off and there is also a program on freewarepocketpc.net that keeps backlight on, o and btw are u the Terrum from tfc and the specialists, i still play tfc and ive talk 2 terrum before on the specialists.

-maybe this prpgram will help you:INCALL SCREEN TWEAK .
-This app will turn your screen off while you are talking and turn it on while you are looking at it (for example, to write a note or whatever).
-It works using the light sensor.
-Hope you like it!

The one and only. Add me on steam if you want to talk. (Considering my signature is related to you knowing me, it's obvious i'm the Terrum you're talking about I made up the name and i'm the unique Terrum)

Thanks for that. It's helped alot. Is there anything a HTC can't do Lol.

screen off button is partial sleep?

When I hit the power button to blank the screen, it definately turns off the GPS and appears to turn off a couple of other things as well.
Can anyone corroborate that pressing the power button to blank the sceen is doing a lot more than just blanking the screen?

I know you can have things set that way. Such as wifi turning off with the screen.

Is there a way to turn off the screen without turning off the GPS?

If you have, for example, Google Maps open and want to check your location, it can be a pain to wait for the GPS to re-initialize when you turn the screen back on. It would also be useful when using Position Test or GPS Test to not have to keep the screen on while you're using it. It feels like a crapshoot every time the GPS turns on whether it will function properly.
Does the GPS turn off with the screen when Navigation is running, as well?

I don't know what I have set differently but I've had the gps shouting out directions with the screen off. I kind of like it, less distracting. Now as far as reliability ... It sent me completely in the wrong direction once and couldn't find satellites another time when I was completely lost.

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.

Lost LED backlight for home/menu/back/search buttons

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

Dimming and screen shut off when on call

Can't for some reason find an option anywhere on the phone to stop this from happening. Every time I'm on a call after about 10 seconds the screen will dim and a few seconds later goes to black. Can tap on screen 2x to wake it up again but I don't want this to ever happen. Not connected to full device shut down that I have turned up to 5 mins so has nothing to do with that setting. Can anyone assist and help me stop this form happening all the time? Many thanks!

Go to Settings/ Accessibility/ Screen reader/ Under Voice Assistant tap settings then scroll down to Quick Menu, tap it, then look for Dark Screen toggle. Click this setting off.. Let me know if that works for you.

Thank you! I turned it off. Next time I'm on a call I'll see if it did the trick and post back.

Not sure then because that was the only thing I could find.. Maybe it's a setting that we don't have control over.. I do know that the screen is supposed to shut off when it's close to your face and the reason being is so that your face isn't pressing on stuff and making the phone do things you don't want it to be doing.. My moms face sure does seem to disable a lot of stuff like fast charging and even turning the screen brightness so low that she thought it was broken haha..

HA. No, phone is on a desk, not near my face. But yeah most phones nowadays do that. Thanks for trying tho.
Anyone else with any thoughts?

Tried replicating the problem on my end. I called someone, enabled speakerphone and put the phone on the table.
The screen indeed turned dim after 10 seconds and turned black afterwards. It bypassed my screen timeout setting which is 5 minutes. The phone app is in the foreground. Double tapping the screen wakes it up.
I minimized the phone app; the homescreen is now in the foreground. It adhered to the 5 minutes screen timeout setting.
I guess the temporary workaround is that after you answer the call, exit out of the phone app.

Hi. I had the same problem and found the solution using third party application: Screen On Call from Google Playstore: https://play.google.com/store/apps/details?id=com.vorlan.screenoncall.free
It is compatible with Samsung dialer. On the top later you have small button to prevent screen going dark or to disable it. Proximity sensor is working without problem when you hold the phone to the ear.

Yaaawhoooooooo!!! This totally works. I have been an Android user for years and could find an answer for this nowhere. Users, be sure to turn on "Appear on top".
Thank you. Life changing.
