On my Galaxy Tab the 4 function keys (Menu, home, back, and search) only light up when i lock the screen and then wake it up. But as soon as I slide to unlock the screen the 4 function lights go off. The only other condition when the keys light up is when I touch the keys, they do a quick flicker. During night time, i am unable to see the buttons to press unless i randomly smash around to locate them. Is this normal behavior, or are they supposed to always be turned on when low light light is present, and the screen is active? Is anyone else having, or able to recreate this problem?
My tab is rooted via Z4root, and I have replaced my WPA supplicant file. This tab is the Verizon version.
Mine doing the same thing... exactly... vzw tab too
z4root, koush method -> ext4, cwm
pre root or after root?

Had this same problem with a VZW tab. Returned it for a new one and the new one worked fine except that my icons would disappear on reboot. Returned it for an ATT tab and it works great.
Did a Factory Reset, and now it works fine.
Dark Function Keys -- SOLVED
I was able to replicate this problem and this is what I found.
The Galaxy Tab has 7 choices for Screen Time out:
15 seconds
30 seconds
1 min
2 min
10 min
30 min
1 hour
I was using a program called quick profile, which is awesome, but it has settings for screen timeout that don't match. When i told the screen to never timeout via quick profiles, it would instantly break the function lights. If i turned it back to something like 10 mins, the light came on again.
I wonder if there are any other apps out there which cause invalid settings.

For some reason my device has suddenly started switching to the minimum backlight setting whenever it's switched on. If I go to the backlight settings and then adjust the slider it will stay at the selected brightness until it switches off. When it switches back on again it's at minimum brightness and I can hardly see the screen!
This started happening after I installed and then removed PocketZenPhone.
I don't really want to hard-reset the device unless I absolutely have to - does anyone know what registry key sets the default switch-on brightness?
Thanks,
I dont have the solution but I have had the same problem intermittently. Can be really aggravating in the dark because it can be hard to get to the proper screen to increase the backlight. Hasnt happened in a while. Have not been able to figure out what triggers it. Have not installed PocketZenPHone. Curious if anyone has an explanation.
yah, i've noticed this to, sometimes i'll hit the power button to take it off standby and the backlight would be off. first couple of times it scared the hell out of me cuz i thought the screen had broke or burnt out.
also i noticed the version of spb pocket plus i'm using (3.04 build 4195) doesnt adjust the backlight brightness.
Now that you mention it. the SPB Pocket plus backlight does not work for me either. Strange...
Well I think I've managed to "fix" this by setting the following;
Backlight Settings:
On battery power, turn off backlight if device is not used for [5 min]
Turn on backlight when a button is pressed or the screen is tapped
Power Settings
On battery power: Turn off device if not used for [3 minutes]
I think the key thing here is to have the device auto-switch-off BEFORE the backlight timer kicks in. Since setting the above three settings I have not had the same problem again.
Ill give it a try as well.
Hmm...maybe someone can help me. One day, my backlight timer settings when the PDA's not plugged in reset to 10 seconds (in the registry it has it as 7 seconds). I'll go in and change it to 2 minutes (the original setting I had it at), but the minute I turn it off, it resets back again to the 10 seconds setting. I even tried going into the registry and changing it, and it resets it back to 10 seconds. I suspect it may have something to do with an entry in the "scheduled tasks" but it looks like a complete mess. Is there some kind of scheduled tasks cleanup utility?
Thanks,

hello i have the same problem using phothet with WM6
Thanks

I had the same problem often about 15 months ago - it happened often each day.
I posted herw but had no joy with a solution - but then found one on Modoco (i was looking about March/April 2006).
Even with that - it has still done if perhaps five or six times since - and basically makes the phone unusuable if it happens somewhere or time with poor light.
My KJam backlight keeps changing by itself to dark
Suddenly my KJam backlight always turns to low without me doing so, then I have to change it to high, barely can see what I’m doing as it is almost black. This is kept happening especially after I installed Pocketweather. I reinstalled the Rom, it worked fine then suddenly it is back again when I switch the screen off, or automatically it is switched off, the backlight slider I find it at the lowest end.
Why thus is happening, it’s driving me crazy, please help me
I have a HTC Magic from Orange (PL), unmodified, without root access, Android 1.5 out-of-box. Recently, I've noticed annoying issue on my phone. If I don't press "end call" red button to turn screen off, it will be on forever - the phone is on the desk for 15 minutes, I'm not touching it, and the backlight is still on, with my Android desktop (not lock-screen) on the screen. It's look like there is no timeout to turning backlight and screen off, although this was working some time ago. I've tried to change settings like timeout value in minutes, WiFi sleep mode etc. but without success. It is so annoying that I have to remember now to press red button after using a phone. Anyone can help me?
P.S.: I don't have aFile or Dark Keys installed.
You may have noticed the discomfort for to turn off the screen with the little side button.
The screen can be activated with the home button but it can not be turned off !!
are there also a widget x turned off ?
I tried the various forums but have not found anything.
Someone knows something, there is a solution?
Thanks

Free: lockenabler
Paid: screen off
Lock Enabler is good & free
can put it on home screen as widget.
only thing is that it need to count down at least 3 seconds to turn off screen.
Don't know if you guys are having the same issue with Lock Enabler, but after awhile it seems that it changes the system screen timeout to 3 seconds (or whatever you set it to).
It was good, however, with this bug I had to uninstall it.

I had the same problem. Very irritating. That's why I bought screen off.
Hi there. I'm currently having an issue with my S7 edge where the lock screen won't turn off after some time. The screen does turn off when I'm using the phone normally from the main screen after some time passes but it's just the lock screen I have issues with.
Whenever I charge my phone or just hit the power button once to see notifications on the lock screen, it'll just stay like that until the same time the main screen timeout configured time passes (5 minutes) and this is getting annoying and somewhat draining a little bit more of my battery. Previously it was working fine and the lock screen would turn off after around 10 seconds or so.
Has anyone faced any similar issues with their phones? I haven't tried a factory reset yet but I'd want that to be a last resort.
Clear Background apps.
It happens when you left some games or apps by pressing home button but it keeps running. Hope they will fix this soon.
Have you tried pressing that little button on the right side of the phone? That usually helps.
Yeah...I already tried that with no luck. Even tried uninstalling some recent apps in case one of them was cause but it didn't work either. Any other suggestions?
The issue isn't with turning the phone screen off by pressing the power button, it's the lock screen itself not turning off after a few seconds when it usually does.
I'm having the same problem, had good lock installed thought that may have been the problem but after uninstalling that I'm still having the same problem with samsungs oem lock screen. I too would like an answer or fix for this. also to note, in developer options the stay awake is off and no apps running in the background.
I am having this problem now also. The screen will lock, but the display stays on but dimmed. I can tap the screen and it will get bright. Now I must click the side button every time I set my phone down or the screen will drain the battery.
I'm facing exactly the same issue. When the screen is locked, it stays on for the same time confirmed to when its unlocked. For example, 1 minute, instead of 10-15 seconds.
Any workaround discovered for this?
Did anyone find a solution to this problem?
I thought that I might've been the only one! This problem only appeared on my phone after the Nougat update, and it's extremely annoying as I rely on notifications waking the screen for my main messaging app.

Hello, I am having the same issue in my Redmi note 11 pro plus Phone. In my case The screen will lock but display stays on with dimmed light. Usually it is not visible during day, but in dark room its visible. And it stays the same way whole night. And battery is fully drained and phone is turned off. Is there a solution for this??
So my mxpe lockscreen wasnt timing out at all, using latest google phone wakes up the device leaving lockscreen opened and if plugging in the turbopower waking the lockscreen it would stay opened. I found this solution to work.

Ok. So recently I used "power saving" mode. I took it off immediately after I didn't need it any longer. For some reason, the Android system on my phone didn't register that, so my phone lock screen kept time-outing after 3-seconds (kinda annoying when trying to use Samsung Pay).
Anyways, do what I did: simply go to Settings>System>Battery>Power Saving Mode>On
Then just turn it back off. Kinda like cycling it, but only once. This time around, my Edge seemed to pick it up, and register it. My timeout screen is now longer than those annoying 3-seconds.

I guess it didnt fix it. The sleep when in active is set for screen and lock screen. This sux. I have sleep set @30min so my lockscreen will stay alive for 30min.
Found a real solution that works. Found here.

Some stated to goto developer options/running services and kill one by one each service and power off the screen and back on till timeout works on screen well I did this and found that Material Notification Shader kept the timeout screen from timing out so I disabled the app and I have a timeout on the screen after I power on the screen and/or plug in the power cord.
