Backlight turns off after 10sec

Here is my trouble:
When I change the backlight timeout to 30sec in the GUI under the Backlight, Battery Power tab, it resets back to the 10sec default after power cycling the 8525.
I do have an HKEY_CURRENT_USER/ControlPanel/Backlight/BatteryTimeout that changes from 7 (Value Data) to 30, when I change the GUI as mentioned above. However it doesn't stick, and changes back after a power cycle.
Any ideas?
Thanks,

Registry changes aren't realtime. If you're resetting the device too soon, the change won't take.
Wait a few minutes after making the change before you power down or reset or try to change it again.

I've changed the setting in the GUI & in the registry in the morning, and at around 14hrs later, reset it, and it still changes back to the 10sec default.
Any other idea's?
Thanks,
Steve

This problem has been discussed many times on several fora. One such thread is:

Are there any other updates/solutions to this backlight resetting problem? Mine started doing it after a hard reset and it's driving me nuts. I've changed the same registry settings as suggested above, but no effect.
I don't want to hard reset again as it was a major pain to get things going on my 8525 again and I really don't want to uninstall a bunch of programs (I have a ton on mine).
If worse comes to worse, I'll wait for the official AT&T WM6 update to come out next month, but I'd like to see if there's any other solution for now.
Thanks!

I think I found something. The backlight timeout stays set until I lock the phone using the today plugin. As soon as I do that, the 10sec timeout is reactivated.
I'm running VP3Gs V3

I've gone for the easy option, given that I don't fancy either uninstalling applications 1 by 1 until I find the culprit or having to hard reset and rebuild the device all over again.
That option is to disable the backlight turn-off setting and manually do it myself after using the device.

It appears that you are right. The "device lock" today plug in does not appear to re-enable the black light turn-off setting if it is off. If it is on, it does change it to 10sec through. Good to know.

Screensaver that powers off screen but leaves device running?

Hi,
I've searched for several hours now in these forums and on Google, with no success.
I need an app that leaves the device switched on, but powers off the screen.
In settings/power I can dim the screen, but there is no setting to dim it completely or just switch it off.
I've found screensavers that can show a blank screen, but the screen is still actually powered up, just showing a black image presumably.
I've found apps that can switch off the screen. But you have to manually click on them to switch off the screen.
Does anyone know of a screensaver that after a set interval will leave the device running, but power off the screen please?
Suspend is no good, the device must be up and running apps.
Thanks for your help.

What apps are you trying to "keep running"? The only thing that might be an issue when the screen goes into it's normal sleep mode is that audio will stop outputting, and wifi connections will suspend, but there's cabs available here to easily get around both of those (and keep them going even when the screen shuts off).

Well, it's actually to solve another long-running problem that has made me almost lose the will to live....
Alarms don't go off reliably on my TP2.
Sometimes, randomly, the alarm doesn't go off until I press the power button to wake it up. The the alarm instantly goes off. So, if I set an alarm for 6am, sometimes the phone wakes up and the alarm sounds, sometimes not. And if I switch the phone on manually sometime later, at 6:15 say, the 6am alarm sounds then.
It will work fine for a few days, then fail.
It happened on WM6.1 and still continues after upgrading to WM6.5.
I have spent countless hours googling and searching XDA-Dev. I have tried probably ten different alarm apps, with no luck. I have hard-reset various times. I have tried various recommended registry tweaks. I've tried checking the notification queue regularly for any errors. I've tried so many different suggestions, for example, never pressing the power button to turn the phone off, only ever let it hibernate automatically. Warm-resetting it each day. And the list goes on.
So, I'm experimenting with just leaving the phone on forever. But turning the screen off at night to save power / not shorten the life of the screen hardware.
Which leads me to the question about screensavers which actually power off the screen automatically after a set delay. Just like a normal screensaver on a PC.
It's hard to easily convey the frustration I have for the TP2. An excellent phone. But a phone which I can't trust to do the simplest thing: to wake me up in the morning?
It'll end up in the bin at some point very soon now.....

A suggestion
Hi,
In my opinion there must be an application, change or customisation that is leading you to those problems. My suggestion is, to perform a sync towards any computer or server to keep your contacts, then, hard reset and keep the phone with the factory defaults for a while. Then, test the phone's alarms and if all is okay, add one by one your applications and changes, testing the alarms in between. Please do that on the official ROM (whatever 6.5 or 6.1) but official one. You will flash if needed later on.
I know it will be a pain, but you will find the problem.
I am using a TP2 with stock WM6.5 ROM. I have not had yet any issue with the alarms. However, I remember to have had those kind of problems before with WM 5.0 and 6.1. There were always related to freeware applications, customisations, no official ROMs, registry hacks and restored backups done from older builds upon upgrade. The alarm bug in old WM version was also known, but I have not experienced it on newer versions.
There can be some issues with the notification database by times, but as said above, it is almost every time due to customisations.
I am not saying that we should keep our phones without applications, third party software, cooked ROMs, customisation etc. But the goal is to find out what is the reason, and believe me. It is the best if not only way.
If you post the list of applications and hacks that you have in your phone, I can try to see if there is any I could identify like guilty one, based on my own experience.
Complementary, I recommend you to install and use these two applications in attachment. They have worked for me on WM5, 6, 6.1 and 6.5 so far. They are freeware and therefore you can use them without problems.
Good luck!

Thanks for taking the time to reply. All very good advice. I'll have a go when I've got some free time again. In the meantime, has anyone come across a screensaver that actually powers off the screen please?
Thanks again.

do you turn your ringer to silent or vibrate when you go to bed? if so,
go to start/settings/clocks&alarms/more and make sure that the "sound alarms box" is checked. this will make sure that even if your phone ringers/alerts are off, your alarm will ring. also, if you charge your phone while you sleep, go to the backlight settings and uncheck the "turn screen off on ac power" box. if you cant sleep with the phone light on, set it to max dim on ac power and flip it over. i always had this issue when i had the tmobile wing.

S2U2 on this forum.

try g alarm.it worked perfect for me with tilt

I have similar Issues with my TP2;
I notice that it is more to do with HIBERNATING than screen off.
My TP2 has go to the point where allowing it to go to hibernation means Screen of Death.
Overnight I charge it and do not let the screen go off and it seems ok (so far).
Guess I will have to Hard reset and test my freeware.
Cheers

I had the exact same problem. When the phone goes to sleep, it is ASLEEP. I didn't use the alarm too much but the phone would never notify me when SMS arrived. I'd hit the power switch to check, and bam, three messages arrive at once, some from hours ago. Immensely frustrating, but the problem went away when I installed Energy rom.

[Q]Cannot lock screen automatically

My nexus4 cannot automatically lock the screen anymore, The setting is that it should turn off the screen after 1 minutes, but the screen just keep on light all the time, the only way is pressing the power button manually.
The ROM version is 4.2.1. Do anyone have the some issue? How to resolve it? Thanks a lot.

Mine locks after a given time. Try rebooting and report if it changed something maybe... Or try changing the screen off time (for ex. try 15 seconds).

Change given time does not work , after reboot it is OK, The question is it will not lock automatically after a few time use.
Really strange....

Is your phone rooted?

No, after deleted some apps, it works OK in the last two days. May have some relationship with the apps.
I will keep watching...

[Solved] Screen won´t turn off - only dim down

Anyone else having a bug where the screen does'nt turn off after the designated time out is reached? I have set mine to 15 seconds but it only dims down after 7 seconds and remains dimmed forever and ever.
Only way to get phone to work normally is to restart it. But the bug keeps coming back every day, sometimes serveral times a day.
Now I have to turn off screen manually by pressing the powerbutton.
Update Solution:
I actually had locked(in recents) Edge browser into the memory so it always would be available lightning fast. I just unlocked and closed it from recents app, and now the screen shuts off normally. Apparantly there was probably a hidden ads-page active somewhere keeping the screen from shutting off properly.

Not much, only the Force all apps to be resize:able.
The screen awake while charging is off. USB-debbuging also.

I have encountered this bug occasionally, a few times this happened some web page was open (No video was playing) not sure if this was the case with you sometimes some ads or something on the web page can keep the browser active. I did not think much of it nor explored it much but will keep an eye out if it reoccurs.

Turn off Developer options for now.
Does it happen in Safe Mode?
Make sure a 3rd party app isn't the cause.
Clear system cache on the boot menu.

Big Thanks! I actually had locked Edge browser, Telegram and File Manager+ into the memory so they would never be killed off. I just unlocked and removed them all, and now the screen shuts off normally. What a relief [emoji846]!
Using Adguard adblock and Edge content blocker so it might have been a hidden ad of sorts keeping phone screen active.

Glad it worked, I suggest copy paste above text, what you observed the reason was for this to happen and what you did to fix it and add that information to the first post. Trust me it will help many.
