Hi,
Received my brilliant brilliant kaiser today. Every penny worth an upgrade from trinity apart from a slight brick feeling.
I was wondering if someone knows how to keep QWERTY keyboard lights on all the time while you are using the keyboard. At the moment they stay on for few seconds when keyboard is opened, but turns off later and don't turn on even on pressing keys unless you close and open the keyboard. It would be helpful to type in dark if backlight on keyboard keys stay on as long as keyboard is open.
thanks
heh i use the low tech way, i put my finger over the light sensor
I am wondering the same thing. There is an option for "Automatic keyboard auto sensor" for the backlight under "Settings....Buttons....Backlight" but haven't been able to get it to work. Where is the light sensor? I could possibly go high tech and put tape over it!
Update:
In the Registry, navigate to:
HKEY_CURRENT_USER...Control Panel....Backlight....QKeyLedTimeout
and change the default value from 10(seconds) to something high eg. 180 (3 minutes).
This will keep the backlight on for the specified amount of time.

so say you only need the keyboard for 1 min, when you slide it shut does it stay lit for the other 2 min or go off when closed?
One last update....the above registry mod actually will keep the phone button backlights on for the specified time as well as the keyboard backlight. So, this could be a bonus for some. Still haven't found the light sensor on this device I am guessing it is on the keyboard on the left side (tiny hole), but I still haven't been able to activate it. Anybody else had any luck?

It will go off as soon as you close the keyboard

Unticking this option actually fixes the issue... If you DON'T enable the auto-sensor, the light will come back on instantly on every new key press (any key..).
Stretching up the time-out with earlier suggested reg-mod is a nice added bonus...
The sensor is slightly left from the Q-key. A little black dot.
Strange,
I put my finger on top of it, and it did not light the keyboard

Yeah.. my light sensor is iffy... Maybe it is just a bug.. I can be in a totally dark room and they key backlight will not turn on. If i disable the auto sensor the backlight, of course, works as normal.
i think i will have to leave it disabled..
Auto Sensor on p4550
Hello,
I have a kaiser and my auto sensor is not work.
Anyone have auto sensor (for light keyboard) work on his kaiser ?
Thanks.

@++++
That is exactly the same problem as I am having. I can't seem to get the keyboard to light up in complete darkness. My other devices never had this problem. The backlight would come on in darkness. Any suggestions?

Most of the time it works for me.. The easiest fix it to simply disable the light sensor. It works just like any other PPC then. If it is misbehaving a reboot will fix it for a while. I haven't actually had any problems for a bit now. I wonder if it has anything to do with the lock password bug? I did disable my lock password and haven't had any problems since.. might just be a coincidence. Wouldn't hurt to try that too just to see.
I need help with identifying the problem why my proximity sensor isnt working. This gets annoying because my phone turns the screen off when making a call and you can turn it back on since it thinks something is all the time in front of it. Is it maybe dust? On which side is the sensor located? Is there any software update for a proximity sensor?
If I type in *#*#0588#*#* that runs the proximity sensor test. The screeen goes green, vibrates and stays on 1 all the time( doesnt flick between 1 and 0 if I i move it). What can I do?
I've got a problem with mine aswell. It is always 0 in the test (it can't sense if i put anything over it).
It use to work but suddenly sort of died. I'm not sure what the problem is too but I would like a fix if anyone can come up with one
Funny thing though, my proximity sensor worked fine for 1 call this afternoon, but failed again soon after. :/
Looks like this is one big riddle for the samsung galaxy users. :/
I made a discovery.. If i shone a bright light on my sensor and held it really close to it (like 0.5-1cm away) then the proximity sensor would react and say something is covering it. Only works with a bright light though :/
How bright is that light? May I ask you what are the other 3 values of your sensors?

hmm it was the flash from my digital camera. I think any decent light would work. Try a torch, if that doesn't work try something a bit brighter.
As for the values, which 3 values do u mean?? sorry
Light, magnetic, accelerometer.
Which rom do you have?
ciksas said:

oh, the values for accelerometer work fine, the xyz values react as they should when i move the phone.
Light sensor goes as high as 15000 lux when I shine the light on it.
Magnet sensor: 2 and the xyz change and react as they should. same with Azimuth Pitch and Roll.
As for the rom, I'm on darky's 10.1 Extreme Edition
As I thought my light sensor is also faulty. It goes only from 0-22lux
My solution

I don't know if this helps, I had a similar problem.. After i made a call my screen would not auto turn back on for me to disconnect the call.
It may have been coincidence, but after i disconnected "Increase volume in pocket", everything started working properly again.

Sorry, I should had given this information. This happened on a S4 (I9505) android version 4.2.2.
I don't know if this particular phone has the same menus has mine, but its how i solved my problem.
Having this issue too.
Nothing mentioned so far has worked for me.
Galaxy S4 SCH-I545 on VZW running 4.2.2.
Unfortunately I don't know when it started so I can't pinpoint any apps as possible triggers. However I have tried out all sorts of apps status bar apps, active notifications apps, launchers (Apex is my current now)
We just picked up a used Droid for the dev department to play with. The backlight comes on during boot up but goes off as soon as it gets into the OS. Settings appear to be normal (full brightness). Any ideas?
hard reset didn't help. The backlight goes off at the exact moment the buzzer announces the os startup. (if that makes sense)
try using other roms..
Working on rooting and loading a rom right now. I took the phone home with me and discovered the backlight isn't out just very dim. It will change slightly when I move the brightness slider around.
OK, it's now running Steel Droid with the same issue. I have a bright screen in recovery and during boot and a very dim one once booted.
try to un-check the automatic brightness, and set it to full brightness...
if that doesnt work... might be a hardware related problem...
Did that already. Seems like an odd hardware issue. I have full backlight in recovery and during boot.
Here is a video of the issue http://www.youtube.com/watch?v=RxHqN_lycG8
Stupid question: do you have auto-brightness active? If so, maybe your light sensor could be broken.

Auto-brightness is unchecked and the brightness is set to max. There is a very slight change to the brightness when I adjust the slider back and forth.
BTW. It is currently running CM7 with the same issue.
Hello! I have strange problems with backlight
1) back light is turned off -- i can't see anything on the screen with the day light. Changing the brightness in Settings/Display don't help.
2) but, after power off+power on, backlight is OK for 10 seconds, and turns off right after that.
I find the guy with the same problem,but on droid 2 -- youtube.com/watch?v=RxHqN_lycG8
Btw, in "AP Fastboot" mode ("M" key+PowerOn), backlight is don't turn of.
I try some ROMs, they all don't work for me. Only "kexec CM10" ROM have one difference: if I turn the phone off and on, the backlight is turning on for the 1/2 of second, I can see the lock screen, and after that it is turned off...
What can it be? How can I fix it? Any ideas will be very appreciated! I very like my Droid3,and want it back

You'll have to try to turn the brightness up manually. It may be a broken light sensor. If you get in the right light you might be able to see the background and be able to turn it up.

In the dark room, I can see everything on the screen. Unfortunately, brightness in Settings/display does not affect the backlight on my device.
I set the brightness to the maximum, but it still too dark
Is it possible that the problem is in flexible cable?
I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.
i used the app both light senor and proximity sensor are working fine
any other tips that i can try

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!
Tip: use a led flashlight to see what's on the display
Ps. Stock m7

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.
Is the display not broken?

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?
