Touch Cruise Backlight Problem

[sclhtc]

When I am on a call the backlight on my Touch Cruise turns off - I don't mind this. The problem is that when I try to turn it back on it is extremely dim (even if the backlight setting is "bright") and I need to use "Adjust backlight" to make it brighter. In sunlight this is almost impossible to do since I cannot read the screen. Even after I readjust the brightness, whenever the backlight turns off and I turn it back on, the backlight is dim again.

I have tried renaming the \HKCU\ControlPanel\Backlight\LockLevel folder to LockLevelx - this has not worked.

I have tried setting \HK:M\Drivers\Builtin\RIL\EnableFastDormantDisplay DuringCall to 0 - this has not worked.

Help please!

Do you have this problem all the time or you can see this misbehaviour just now?

I'm asking, because this could be caused by some other software you installed on your device,
which does some "things" with the backlight or some call manager like PhotoContacts etc.

[sclhtc]

This happens all the time. It does not happen after I soft reset the device until I use the phone. As soon as I use the phone the backlight turns off and is dim whenever I turn it back on.

[hujer]

- Are you running some "cooked" unofficial ROM?

- if you are using HTC Home, try to deactivate it, just choose some different homescreen schema but not HTCHome, make a soft-reset a try it.

- check HKEY_CURRENT_USER\ControlPanel\BackLight\LockLevel \LockLevel - this should have the value 0

[sclhtc]

- running standard ROM
- deactivating HTC Home doesn't help
- LockLevel is set to 0

This periodically happens on my device too. And it's really, really annoying. I found that one way to make it go back to 'normal' for a while is to change both lock levels (in locklevel and locklevelx to value 1) then back to level 0 (including the waiting and the soft resets) and then it seems to go back to normal again.

what seems to set it off for me is using the call history to dial a number, but this is sporadic.

[sclhtc]

Thank you Marissa and Hujer. Unfortunately both your suggestions have not worked.

I have had the same problem. What helped in my case is deleting locklevel and locklevelx from the registry and then soft reset. Worked for me!!

[sclhtc]

Thanks Tim B but that did not work either. If I soft reset my device OR delete locklevel & locklevelx and soft reset, then the backlight comes back on at the correct level of brightness....until I make and end my first telephone call - then the backlight only comes back on dim. By the way if I delete locklevel, it stays deleted until I make and end my first call - then it's in the registry (with value 0) again.

Exact same happens to me, using Bepe 64 rom. Real pain in the neck.

[Camstech]

This sounds very much like the same problem Trinity users have faced since that device was released. Try searching the Trinity Forums. There was a reg fix...something to do with "fast off" or similar.
The workaround there was, after the phone call, to press the power key to put the device into standby, and then when it wakes the next time the backlight is restored. Try that anyway.

[sclhtc]

No luck with this either.

[Tim B]

I now have the same problem. My earlier solution (delete locklevel and locklevelx) is not working anymore. There must be someone who knows how to solve this.
I am willing to do a hard reset but then I will have the problem again that after turning the phone on when it is locked the display is not readable.
Any good solutions??

I had to do a double reg edit, try this which is what I use:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\RIL]
"EnableFastDormantDisplayDuringCall"=dword:00000000

[HKEY_CURRENT_USER\ControlPanel\Phone]
"Sleep"=dword:00000000

Reboot!

[sclhtc]

Thanks but that didn't work either.

Just to be clear I do not mind the backlight staying on, dimming or turning off during a call but when I press "Call End", the backlight dims (which I do not want) and if the backlight turns off after a call it is dim when I turn it back on (which I also do not want).

[marisa4755]

Did anyone find a solution to this?
Have tried all the things on here, and some work for a little while, but then the problem reoccurs

[maevro]

Wow, this is so strange. Mine comes back on at the same brightness level.

You all are experiencing the same thing as Marisa?

[marisa4755]

It is an odd problem because it seems that it occurrs all of a sudden out of the blue.

One time you make/receive a call and afterwards, even if the call was only a few seconds, you terminate it and the screen either is already dim or then dims and will stay dim unless you hit a backlight changer. Even then, if you lock the phone, or the phone dims after your prescribed time, it then stays dim. The only way to temporarily fix it is to set it to the normal level and then soft reset. It will then behave properly until the next phone call.

It is very inconvenient as if it locks while this is going on, you can hardly see to unlock it.

I have trawled the internet for hours looking for solutions to this. The Kaisertweak does not work for this on this device (don't know why!) Installed Schapps but the very tweaks I need do not appear when installed on my device.

All the registry edits don't work. In fact when I go to do them, the value is already at the recommended value anyway. Renaming locklevel seems to work sometimes for a while, but then reverts back.

I think it is more a problem of undimming than dimming. It dims when I expect it to dim, but does not light up again afterwards. The Kaiser solution of pressing the power button or d-pad to do this does not work on the Orbit.

I have a fairly non scientific feeling that it's something to do with either Shell, Pontui or Co-Pilot. I have uninstalled Shell & Pontui, but it has made no difference. Makes no difference either if HTC Home is/isn't installed/running.

Another strange thing is that when it is in its dimmed state, I only have to touch the page where the backlight slider is for the light to come back up. I don't need to touch the slider at all, it's already where it should be, 3/4 of the way up.

In fact I have done the registry tweak which is supposed to stop it dimming during calls altogether, and checked to see that it 'took' and it is still happening.

Somewhere, there must be a registry key or somesuch which controls what happens after this "temporary" dimming, which says, the call is over/the device is unlocked - go back to prescribed brightness. But I can't find it.

This is a really insidious problem which drives you mad, especially when you are out and working, you don't have time for this nonsense. If all else fails in a week or so I will try a hard reset, i just don't have time right now.
Any help gratefully received.

[marisa4755]

I have just emailed O2 with this problem. Let's see when/if they reply.

[sabre3487]

I have an O2 orbit 2 and had/have this same problem.

I thought it was random but I read somewhere this and tried it and this seems to be the real cause atleast for me. Backlight is fine, then I make a call from my CALL HISTORY, after that the light is pretty much dim no matter what. If i do the registry hack and delete the key locklevel w/ soft reset also having locklevelx as well the problem goes away until I select or make another call from the call history log..

[marisa4755]

Now that you mention it, I can't remember 100% of occasions, but you are right, on at least 70% that I can remember, it was always from the call history!
You may have hit on something there. I will give this a try, never making calls directly from the call history and see if this gives me 100% non problem.

Then, after a while I will try a call from call history again and see if it goes again. Good spot!

[Tanax]

I resolved the problem by this way :

1- PHM Regedit (or any registry editor)
2- HKEY_CURRENT_USER
[____ CONTROL PANEL
[___ BACKLIGHT
[_____LOCKLEVEL
3- Change de value 0 for 100
4- Soft Reset

I hope this help to everybody... bye

[marisa4755]

Am trying it now!

Got no reply from O2, not even an acknowledgement that they had received my email. Nothing. Zilch.

[marisa4755]

so far so good.

The only other thing that seems to have changed is that the light dims immediately on locking the device, and stays dim until fully unlocked. It used to light up on the first unlock press. But this is a small price to pay as I can much more easily 'guess' where the unlock tabs are rather than try to find the backlight settings with a dim screen outdoors!

[marisa4755]

Can confirm, this tweak works!
Thank you Tanax - you have saved my sanity!

[Bodisson]

Testing...

Seems that it worked. Thx m8...

It worked only temporary... :mad:

[FlaTEriC18041983]

hi,
Other backlight related "problem": isn't there a way to make backlight adjust automatically using perhaps the front camera as a light sensor?

when I'm at home I reduce backlight to minimum, because there's no problem working like that in rooms, but when I go out, and sun is shining, I even have problems to see enough to turn backlight to max. again... this sucks a bit...

bye, eric

[Tinnitus]

Thanks a lot for the resolution to this. I was finding it a nightmare listening to voicemails because I couldn't use the keypad to navigate/delete messages as the back light was out!

[XTREEM|RAGE]

I resolved the problem by this way :

1- PHM Regedit (or any registry editor)
2- HKEY_CURRENT_USER
[____ CONTROL PANEL
[___ BACKLIGHT
[_____LOCKLEVEL
3- Change de value 0 for 100
4- Soft Reset

I hope this help to everybody... bye

I have the same prob, gonna try this!!

edit--
It seems to work, tnx!!!

EDIT2---
I think i cheered to fast, because as soon as a call has been made/recieved, the locklevel turns itself to 0 again and the backlight dimms it self.
Bah!!

btw for me its on map further
HKEY_CURRENT_USER
[____ CONTROL PANEL
[___ BACKLIGHT
[_____LOCKLEVEL
[_____LOCKLEVEL

[XTREEM|RAGE]

For everyone it works fine the fix above??!

[tommacx]

Hi I have an Orbit2 ROM 1.25.206.3 WWE ROM DATE 01/03/08

I stumbled accross this post when trying to fix a dim (non backlit) screen when locked (password or keylock) and as Marisa highlighted this as coming about after fixing the phone dmimming issue I thought I would reply.

I found a fix for the keylock dimming via google and have posted elsewhere

http://forum.xda-developers.com/showthread.php?t=384865&page=2

However before I learnt about the fix for the '10 second' problem (backlight resetting to ten second reset on resume no matter what you do - even if backlight timeout was unchecked), i tried setting HKCU\Control Panel\Backlight\Locklevel to 00000002 instead of 00000003 and this fixed the lock issues but created the problem the guys in this thread are having!!

reverting to 00000003 immediately removed the phone backlight off issues. Now that I have both locklevel and locklevelx folders the fixes seem to be permanent as they have survived 2xsoft resets. Initially the lock+backlight off issue was coming back after soft resetting. ( I know this does not make sense but it was 'fixed' without a restart after regedit!)

cheers

tom

Please feel free to remove this if it does not fit in this thread :)

[marisa4755]

That certainly seems to work, but now still my backlight doesn't dim during a phonecall, does yours? If so, after how long?

The ideal for me would be that during normal use, any touch/button brings the light on, during a phonecall the light goes off after say 5 seconds, but comes on again on any touch/button or on hangup. The light goes off after a few seconds when locked, but comes on again immediately on any touch/button.

With this solution I am very close, but the light doesn't seem to dim during calls.

[tommacx]

My backlight is set to turn off after 30 seconds and seems to do this during phone calls as well. I hadn't really looked before but I guess 30s isn't really necessary in call.

Hope you get everything sorted :)

cheers
