Backlight problem - Tilt, TyTN II, MDA Vario III General

I'm having this problem with backlight. No matter what I do, the screen automatically dim after 10-12 seconds. I've turned off the all "Turn off screen after so many minutes" (on battery or on AC). I've changed the backlight settings and it still revert.
I've even watch the backlight setting moved back to minimum from max after that 10-12 seconds.
I can't figured out what is overriding the setting. I don't have much installed:
WM 6.1 with
HTC Home
HHC
BatteryStatus
TouchPal
Wizard_reTOUCHed_Dialer2
Any thoughts?

Settings->System->Backlight & Settings->System->Power
To control BACKLIGHT settings, i.e. Backlight Brightness, Backlight timeout, etc, go to:
Settings->System->Backlight
...and check OFF the checkbox in the "Battery power" tab...or leave it checked ON and adjust the timeout
To control SCREEN settings, i.e. when does the screen turn OFF COMPLETELY, etc, go to:
Settings->System->Power
...and check OFF or adjust the timeout for the timeout that takes the device into standby mode
note that the above two settings applets are linked to each other from within via the Menu softkey
if you have already done BOTH of the above, i've no idea why your backlight dims so quickly

You have batterystatus installed and if you go to the preferences in it you have backlight as an option adjust your settings in there.

Sweet! That was it. Thanks for the tip.

I don't have batterystatus installed. I do have pockettoolman but it uses regular power and backlight settings.
My issue is even without any reset, the backlight setting automatically resets to default 10s. I change it to 2min, but at some point it will reset itself to 10s. This is without reset or turning phone off. I don't know y it does this but its very annoying!
Any ideas? Thanks.

I am having the same problem as well here... the backlight timeout will automatically reset to 10sec everytime you switch on the phone (not soft/hard reset, just normal power on). I am using ATT Tilt with the offical WM6.1 ROM.
Tried to change the setting directly in Registry using Resco, still the same problem. The value got reset to 10 on the next power on.
Wondering if anyone got a solution to this?
(maybe it's a problem for ATT tilt only....some users posted the same problem in the official ATT forum
http://forums.wireless.att.com/cng/...thread.id=99891&view=by_date_ascending&page=8 )

I'm having similar problem with back light and also it is very annoying when screen goes black and kills wifi and gps. is there way to keep wifi and gps on when backlight goes off? thanks.

ATT Tilt Backlight Fix {Maybe}
I have to put this here
"Making registry changes incorrectly can cause system-wide problems that may require you to re-install WM6.1 to correct them. Making changes at your own risk."
=======================================================
Well here some settings to try:
HKCU\ControlPanel\BackLight
There are several settings here with the word "Timeout" in them:
Assuming External Power
===================
ACTimeout
ACTimeoutTemp
ACTimeoutTempUnchecked
Assuming In Battery
=================
BatteryTimeout
BatteryTimeoutTemp
BatteryTimeoutUnchecked
Make them all 300 for 5 minutes
Now one interesting one...
AutoSensor try changing 1 to 0
Test run....
==================
Power on/off using switch etc..
Performed soft-reset using stylus...
Display did not timeout after 10 seconds... But is did appear to power off after 5 minutes...
To soon to say how long this will last, but it definately appears to have made a difference and now seems to last longer. Something like 2 or minutes. Go figure

I was pretty happy with the new AT&T 6.1 Rom until this problem came up. The ROM is fast, the battery life with the 1.65xxx14 radio is good.
After a couple of days trying to fix it based on some solutions I found on the internet, I have given up.
No matter what I did, it always came back even with just having exchange push mail and total commander installed only.
Reverted back to WM 6.0 just because of this problem that was very annoying...
Now I am having a problem flashing a different hard spl instead of the 3.56 on my phone for WM 6.0.
Anyway, so, has the problem come back yet?
Thx
Oz

Still no solution to this problem? I'm a little afraid to try registry hack but am getting desperate.
I also now notice volume resetting issues...volume will change on its own accord to different settings...

The registry tweak fixed problem.
Only changed the first batterytimeout to 96 (2 min).
It now timeouts after 2min and survives a soft reset.
Thank you!

Back light issues Mobile 6.1
I have the TILT with 6.1 installed.... My backlight with default to 10 seconds also.. alog with that when I Turn the phone ff using the power button, if I sit there and watch it the backlight will come on with a black screen. Just backlight for no ryme or reason... I also have the issue of the screen brightness going full bright on me. All of these issues have really taken a toll on my battery life. Any thoughts from anyone...

I found that for some reason (probably Battery Status?) my backlight would always revert to 7-seconds when on battery. Every time I changed it via the control panel applet I could then go and see the value in the registry getting changed to 7. If I manually changed the value in the registry it would always revert to 7 after a short while.
I found that removing the 'BatteryTimeout' entry from the registry (HKCU\ControlPanel\BackLight) and not touching the Backlight control panel applet (or changing Battery Status) prevents it being automatically updated to 7-seconds and applies the default of 30-seconds.
I am not sure if this will work for you as there seem to be variable results, however for me this works perfectly. I have all my defaults set in my custom ROM so I never need to change Battery Status or open the Backlight applet and the default 30-seconds for the backlight is set.

Just to confirm I have just extracted the 'backlight.dll' file from the update posted on HTC's website and cooked it into a ROM, replacing the original 'backlight.dll' and it does indeed solve the problem.
I have played around with the backlight control panel applet and opened and closed Battery Status and the delay remains at what is configured - 30-seconds in my case.

Scratch what I said in my previous post. With this updated .dll file the behaviour of the backlight is worse. I have done some testing today with the updated 'backlight.dll' file cooked into a ROM and it's painful. No matter what I try the registry values 'ACTimeout', 'BatterTimeout' & 'timeoutsaved' are ALWAYS reverted to a value of 8 once the keylock has been applied. In my case either by Battery Status (keylock on resume) or pressing the today screen icon. This results in the backlight dimming after 8-seconds when on either battery or AC, the only way to resolve is to either go to the backlight control panel applet or edit the registry directly. Hit the keylock though and your back at square one
I have now re-cooked my ROM and replaced the 'backlight.dll' for the previous one and the behaviour returns to normal. So my advice is don't install this patch or cook it into your custom ROM.

Thanks so much for this post. I have been trying for days to get my back light to stay on and nothing worked. As it turned out I was only doing the setting in the backlight tab, not the in the power tab.

Finally!
Click Here for the .cab that fixed my unit. I got it off the ATT forum.
NOTE to all... Even this fix did not solve my problem until I checked the boxes to time the backlight. I like the backlight feature on all the time. If I don't want to see the screen, I turn it off.

Screen Lock and Backlight

Is there a hack to not have the backlight automatically dim out when screen locking the phone? Any help appreciated on this. Thanks.
Yeah, use search. There's a quick & dirty fix that helps until HTC wakes up. It's in this thread somewhere.
Thanks,
I did search quite a bit. The fix I found was to diable the screen shutting off during a phone call. I haven't been able to find the fix for the backlight dimming out when screen locking the device.
Search
Hmmmm... Sorry you missed it. I went back a couple of pages and found ur answer; there are two:
1) Easiest remains to switch off-on your TyTN II after call. Ur back to normal then.
2) Option is a small app, written by Magxs that wakes the baby up after disconnect. See more here: link.
Hope this is of use.
edit: by the way, this only seems to happen to password protected systems. That is an option - switch off the PW. Lot of us can't due to corporate (exchange or goodlink) security pollicy.
Thanks Nukenine, however, this is not the issue I am questioning. Regarding the issue that you are speaking about, the following is the fix:
Modifying the DWORD stored in:
Code:
\HKLM\Drivers\BuiltIn\RIL\EnableFastDormantDisplayDuringCall
from "1" to "0" will leave the screen on and will fall back to the backlight/power settings
My question is when I key lock my device (the action that we can have on our today screen which says "Device Locked" or "Device Unlocked"), the screen automatically dims out. And when I tap on the screen, it stays dim, it does NOT become bright again. So, I am asking if anyone knows the registry hack on this issue. I hope I clarified what I am trying to find. Thanks again.
Sorry for misunderstanding.
It is a very easy fix.
HKCU\ControlPanel\BackLight\LockLevel\
Change LockLevel to something other than 0. I use 4. The number indicates now many notches you have the slider moved up in the back light control panel.

Hey Jason,
Thanks for the info. However, when I change the number to 4 (I even tried 9), and then I screen lock my device, my original Backlight setting (set to turn off in 30 Seconds) changes to 10 seconds. When I unlock it, go to the backlight settings, change it back to 30 seconds and then lock it, it changes automatically back to 10 seconds. So the hack works, but it gets rid of the backlight settings and changes them to the ones mentioned above.
The more serious issue is when I soft reset the device. It seems that the number I entered into the registry path goes back to the default "0" automatically. I tried this three times and it always goes back to the "0" default, rendering the hack useless.
Any advice?
Thanks again.
Jason, any advice on the above? Is it possible it is because of the registry editor I am using (Resco Registry)?
Sorry it took so ling, been busy.
That is odd.. I guess i hadn't rebooted in some time.. Mine goes back to 0 as well. It doesn't have anything to do with your registry editor. Something is changing it back on boot. Probably one of the HTC services or something. So there may be no good fix for this.. Other than someone writing a program that will change it back after start up.
I don't have my back light ever set to go off after a time.. It seems pointless to me.. Just have the device power off after a time. Saves more power than just dimming the back light.
anyway.. i have not seen the issues you describe with that but i don't have it set that way.

Thanks Jason, I appreciate the reply and feedback.
This is bugging me too. I hope we find a solution for it soon. Is there a place in registry where startup programs can be defined? If yes, is there a silent tool we can use to import a reg file in the background at startup?

Registry Comparisons Before/After Exchange Sync

Friends,
I am using Rottohammer's Rom 6.1 and am very pleased with this product. I have done some serious searching to fix my error and I keep hitting dead ends.
This is about the issue with the backlight turning off at ten seconds. I have performed a hard reset, no problems with backlight. Enter my exchange settings and sync, the problem with the backlight starts and turns off.
Deffinitely driving me to my grave!
Anyways, I was thinking about comparing the registry before/after synch to exchange. See what has changed and maybe I might find the answer and solve this nightmare of a problem.
Is there a program out there that compares the two registry's and lists the changes? I have looked in the registry itself, found the backlight registry key, made changes and value's do not hold. I give up!
The only work around I have noticed is to change the settings in the backlight, energy to increase the time-out. However, after a soft reboot it reverts back to the ten second backlight time out.
Please advise if someone has the fix for this or a registry comparison app.
Thank You,
Tvos

[SOLVED] Backlight doesn't turn off when using TomTom...?

TomTom v7.450
Diamond ROM v1.37.405.1 WWE
Can anyone else confirm that their backlight never turns off whilst using TomTom, regardless of what setting/timeout they've got on the device's Power config page? Whether I'm using it on battery or mains the result is the same - backlight remains on continuously. If I shut TomTom down I then see normal behaviour and the light turns off after the set time.
Interestingly, if I install the very same TomTom CAB on my M600/Prophet it behaves correctly i.e. the backlight turns off after a time. The device remains continuously on, regardless of setting, but then that's what I'd hope for anyway as TomTom is no use if the device is not active.
Given the above, has anyone got any ideas as to why this might be the case, and what I might be able to do to solve it? I really want the backlight to dim as it will save a considerable amount of battery should I be using TomTom on battery... and it would automatically turn it back on when it comes to advised turns etc.
Incidentally, the backlight does dim/brighten in response to changes in the ambient light level so that's at least something - however I tried removing this setting in case that was the problem but it wasn't.

I also use TOM TOM on my Diamond..and I think that is normal that the backlight is on when using the navigato..also if you use the Stand Alone navigator the back ligt stays on!
I can't see the use of the navigator with the device in standby..you should buy a car charger so your battery recharge during the utilization of navigator

I have a question, can this problem co-exist with the problem of backlight turning off too fast when making a call, or do these two problems cancel each other ?

this is a feature (and a good one) and not a bug. i bet you don't want that when driving, right before a big intersection yr screen go off....
for example,the igo (that's what i am using) give you the option to go by the device or all time on.

If it was a feature I would expect it to manifest itself when installed on both the Diamond and the Prophet (given the common application) - the fact it doesn't suggests to me it is a 'quirk' (not necessarilly a bug) with the way it works on the Diamond. As mentioned, the backlight used to come back on when being advised of any directions etc and would remain until well clear of a junction so if it is a feature it's an unnecessary one!
Sometimes it is not convenient for me to use external power - when riding on my bike for example. And in such circumstances the high ambient light level used to be plenty sufficient for me to see the screen on the Prophet without the backlight being on - this is obviously great for conserving battery power as the light ranks as one of the highest power consumers.
I might see if the TomTom menu is still customisable and, if so, include the 'Backlight Preferences' icon that was present in versions of Navigator prior to v6.

interesting! didn't know that...doesn't bother the on\off of the screen while navigating in town (lots of instructions)? not sure i'll want all this flickering
Solved it!
In fairness, it seems that it is a TomTom quirk.
Specifically, the application has always (since I've been using it from v5) had a built-in setting for when to turn the backlight the backlight off (or, more accurately, when to allow the device to turn it off in accordance with your time setting) - the options being: 'Always', 'When on a walking route', 'When not charging' or 'Never'. The default being 'Never'.
However, since v6 the button to change this setting disappeared from the menus however given it is possible to customise the TomTom menus and, even better, to include icons from previous versions of TomTom (assuming the feature is still supported internally) I did the following to turn my backlight setting to 'When not charging'...
- Create a file \TomTom\SDKRegistry\TomTom.mnu in the root of the device
- Inside this file put the following:
Code:
MENUBLOCK|BLOCK_MAIN|BTM_DONE|
MENUPAGE|TASK_PAGE1|Main Menu|
MENUITEM|TASK_EXIT_APP|
MENUITEM|TASK_SET_BACKLIGHT|
MENUITEM|TASK_PAGE1|
- Now run TomTom and click the main screen - up will come a menu with two items in it - Exit and Backlight Preferences, the latter will allow you to configure exactly how you want the backlight to behave.
- Quit TomTom and delete the TomTom.mnu file - this will revert you back to the stock menus, but with the backlight setting (permanently) set.
Of course, this process can be used to configure your menus exactly how you want them however I don't know the keys for all the icons - only for those when I last dabbled in v5 - maybe if I can find some time I'll find the others (I haven't Google for them so perhaps these are now common knowledge) such as the MapShare functions that only came in v7.
The reason it the backlight worked as I wanted when installing the cab on my Prophet was because it still had my menu configs from v5 installed on it... d'oh!
I could be alone in wanting to be able to choose how the backlight is managed, but just in case there's someone with the same desire hopefully this'll be some use to you. It does of course beg the obvious question - why did TomTom remove this customisable feature?!
Cheers,
Mathew
youupy! drinks on you!
congrats and yes, i knew from the beginning that i can help you. dhaaaahh. lol!
Interesting, previous versions of tomtom allowed you to adjust the backlight settings within the application.
cant find it in TT7 though

On the contrary; they've handled it handle it very well.
Say you've got your backlight timeout set to 30 seconds then after this amount of time with no activity (direction instructions etc) it will turn the backlight off - you can still see the map outline in ambient light and, most importantly, can easily see the distance indicator to the next direction.
A few seconds prior to the next instruction the light will reilluminate, a few seconds later it will give the direction advice/distance etc and then once you're through the junction it will turn the light off again after 30 seconds.
Of course, when following a rapid series of instructions in, say, a built-up area then the backlight will stay on continuously - each instruction essentially resets the timer. It's only when out on the 'open road' with no isntructions for miles that you'd see the effect.
All said and done, when I've got access to external power I keep the backlight on constantly (that's where the 'Extinguish only when not charging' option comes in) but when I'm running on batteries I need all the power-saving I can get, not least given the limit battery capacity in the Diamond!

As mentioned they dropped the icon in v6 yet still supported the functionality internally - it's just that with no icon you can't change the setting hence the temporary icon-insertion method discussed above.

Phone screen timeout

on standard tytn II, my phone screen used to timeout a few seconds after finishing a call but now stays on i have recently loaded schaps adv config tool, but have been through the settings and cannot see anything relating to this, maybe a side effect of another setting. anyone happen to know what setting affects this action, reg setting maybe?

[SOLVED] Problem with backlight dimming

When I soft-reset my TD2, leave it be for a while so that backlight dims and then press a HW button or tap the display, backlight comes up back again. However, if the device enters standby the "resume backlight on user activity" function stops working properly for some reason. (I am not sure for how long TD2 has to be left alone - maybe 30 minutes, 1 hour?) Specifically, if the backlight dims and I go to Settings > System > Power > Advanced tab and uncheck "Dim screen after X s", the screen will light up, but if I check this checkbox again, the screen will dim even though I just interacted with the phone and the screen should therefore remain lit up. The only other way to get a fully lit screen (at least until it dims again due to user inactivity) is to lock the phone and unlock it back.
I should also add that this happens with the official stock WM6.5 ROM.
Is there anything in phone settings I should enable or disable, or is there any registry key I should set to some specific value for this feature to work properly again?
Thanks for any help.

Hakim,
thanks for the suggestion, however, in the meantime I learned that the issue is caused by the WM auto-lock feature (it is a bug that nobody cared to fix :-/ ). I was not able to find any useful work-around so I decided to install an application called LockDevice (it should be here somewhere on XDA Devs) which works very well and seems to be relatively light-weight.
Anyway, thanks again for your response.
