Windows Mobile 6.1 ... Screen not going to sleep?

Just upgraded to Windows Mobile 6.1, and for whatever reason, if my phone is unlocked and idle, it no longer goes to "sleep." Instead of the backlight turning off like in WM6, the backlight goes full brightness and displays a white screen. Has anyone seen this before? Any workaround/fix?
Thanks!

Sounds like you got the wrong display driver for your phone. What phone and what ROM are you running ?!

I've had this problem before!
It happened when I was playing with the power management settings in the Registry. I found if I then locked my phone (e.g. long press of hang up button), the screen would time out and go completely white on full brightness.
To fix it was easy enough - just change the power management reg keys.
Once I screwed them up soo much I had to do a hard reset so watch out before playing.

Mine has been doing this also, I believe it may have something to do with the Light Config option in CeleTask. Will test more

And what should I change the power management reg keys to?
Could you give more detailed instructions, including which keys to change, and what to change them to?
Thanks!

Yes I believe so too because it only happens when I use the low light option as well.

first off try....
go into power management under settings.
1. backlight time out on battery should not be set to never.
2. backlight time out on AC could but it still will turn off after the time period you have set for the next setting.
3. Display timeout- will turn off the display off completely after the time period set here.
1 and 2 low dim the screen prior to setting on 3
turn lowlight off... it hardly ever works. lol

App to display a black screen/pseudo lock?

Since we need to have the screen turned on to keep wifi/gps etc. running, and there are a few apps that would ideally run in the background with the screen off; to save battery power (and burn in?) it would be nice to have the AMOLED screen display just a black image.
Is there any app out there that just displays a black screen and maybe ignores all but a specific input?
At the moment I just zoom into a black image in the browser, but I can't put the phone in my pocket like that.
(I tried searching for this, but it was beyond my google-fu.)

You dont have to keep the screen on to run either my gps is always on and it neva disconnects also ive spent many nights going to sleep leaving my wifi connected and its neva disconnected either

Yup. If you haven't set WiFi to switch off after 15mins, it should carry on running.
By doing what you proposed, you'll decrease battery life drastically as you'd effectively be disabling the chips sleep mode by keeping it running 100%. With that, only the screen switches off and everything else including Android keeps running. Any application holding a partial awake lock can achieve this.
Lock delay; an app to control the default screen-lock options allows this.
For instance, if you set the initial screen timeout to 2 minutes but standby/lock to 10 minutes in the settings, the screen will switch off after 2mins idling, but the rest of the phone will still be running incl. WiFi/GPS. You can enable a lock/pattern or no lock at all where you press any key including menu/trackpad and it'll come back on in the same place you left it, without any lock. If the phone idles for 10mins, it'll activate the screen lock and place the phone in the standard sleep mode. The max delay you can set the latter to is 24 hours.
I wouldn't advise avoiding the sleep mode unless required in specific circumstances. Battery loss will be drastic; I found out unintentionally when activating this option at the beginning.

Thanks th3, that should do what I want. I don't intend to leave it unattended, it's just for when don't need the screen on while an app is doing something.

Alarms with the phone turned off

I know Android has never had this function on a phone, but is there a way to make an alarm sound when the phone is off? Something like an action programmed to turn the Gnex on and make the alarm sound... If my old phones could do it, why can't this one?

Immediately thought of this, but it's not compatible with the GN: https://play.google.com/store/apps/details?id=eu.chainfire.nomoarpowah&hl=en
I've had brick phones that have that functionality.

If I under stand you...phone screen off, try tasker

Not just the screen... I mean the whole system off.

All the blackberry did when it turned the phone off is turn off all the radios and turn off the screen. and kill all apps except certain system apps. It really did not power off the phone, as if you left the blackberry in this state indefinitely it will eventually kill the battery. Its like a sleep mode. It really did not turn the system off.
For your phone you could use tasker that to create a task that turns off the screen, puts the phone in Airplane mode and kills all running apps to get the similar effect

I don't know about that. All nokia phones had the alarm go off with the phone completely off. You could even pull the battery out, put back in but not boot, and alarm went off properly.

It powered it off enough that I had a phone at 4% for an entire long weekend (ie killed it to the point it wouldn't power on to use anymore, and had forgot charger at work on the Friday) and it still got me up on Tuesday (and Monday :/). I didn't even actually realize the GN didn't do that as I normally plug mine in over night and leave it on.

You said you put the battery in and the Alarm goes off. Just because you did not push the power button does not mean the phones internal clock is still on pulling a small charge to keep the time, and produce a alarm event at a certain time.
Think of a desktop PC. Newer motherboards can actually turn on/off desktops at certain times even with it being completely off. Why? Because it has a small battery running the internal BIOS that can produce power events from an off state
Blackberry/Nokia probably implement this in different ways, but the fact remains their is something that stays on even when the phone is "off"
That's why as soon as you put the battery in for a blackberry the phone boots and takes forever to boot at that. But when you just turn it off with the power button and then turn it on, its back up running in seconds. The device is designed to always be on...even when it seems to be off.

[Q] night time alarm clock

Hi All,
I want to use my Nexus as a night-time bedside alarm clock.
So, I know that I can use the stock clock app, and tap it to make it go dim, but after a few minutes, the screen saver kicks in and the display switches off.
The only way to get it back on is to press the power button.
Is there a way to leave the clock app running on screen all through the night?
Do I have to purchase an actual dock for this?
Or does the phone need to be charging for this to work?
Cheers.

I think a long press on the blank space (turning the background black...not dim) will work?

Hmm, I see that makes a difference (totally black screen, clock in blue), but the screen still switches off after the normal time...

Developers options, stay awake while charging.

Night Mode for Always on Display

Can anyone tell me if there is a built-in "night mode" on the 2XL? Coming from an S7 Edge there was an option in the settings that at a preset time the always on display would switch to a very minimal display that was only across one edge of the screen, it made for a nice alarm clock without being too bright overnight, then at a preset time it would revert to its normal settings of a large clock, displaying notifications, calendar etc.
I know I could use something like Alarm Clock Plus, but am trying to avoid having to install an app if there is built in functionality to do the same thing.
Thanks.

no

Short and sweet. Thanks. There are definitely a couple things Google could learn from Samsung on just small things like that though.

yep. but in the dark the ambient display is not bright so dont be afraid of burning your eyes.

The closest thing I have to what you are asking is using Tasker to turn off AOD when DND is enabled.
I have a profile to enable DND overnight, which in turn disables AOD.

That's not a bad idea, I paid for Tasker long ago (run it on my Nexus 7 in the car) so it would just be a case of setting it up on the Pixel.

There is a clock screensaver for when phone is plugged. I don't use always on display but want to be able to see clock without touching phone. You can adjust tue brightness of it via nightmode switch. Under display - screensaver h clock ...

In case you were wanting to actually implement this, I double checked how I did it, and it's with the paid plugin "AutoTools".

I turn the AOD on when I'm connected to BT in my car since it's on a mount and also off at 10pm. If the task runs when your screen is off you do need to turn your screen on for it to take effect. So I check if my screen is off. If it is I have it turn on and off briefly.
trigger always on using tasker auto tools
New Task
Plugin -> Autotools -> Secure Settings
Configure
Custom Setting
Setting Type = "Secure"
Name = "doze_always_on"
Input Type = "Int"
Value = "0" OFF/ "1" ON

I've done some testing and I can't tell if it even works...not sure if a reboot is required or what each time...maybe someone else can add to this.
The below article might be fine for a stock Rom, but doesn't seem to work on Nitrogen with a kernel/magisk.
You need to have ambient brightness turned on though, otherwise, the default values are used and these overrides don't work.

If you hit the battery saver before you go to bed that will deactivate always on.
Turn battery saver off in the morning and always on will be back on.
Should solve your problem!

Or just flip the screen over. That deactivates it as well.
